Once the accumulator fills, the converting section has to slow down or stop. At that point, a warranty certificate offers little practical direction.

A buyer needs a written plan for bringing the line into production, keeping it serviceable, and restoring acceptable output after a fault. Compare that plan before signing the machinery order, when the supplier can still price the work and assign responsibilities.<\/p>\n<p><strong>Quick answer:<\/strong>\u00a0Look for written warranty coverage, an escalation path with separate response and restoration milestones, a machine-specific spare parts list, qualified field support, and an acceptance plan that uses your paper and products. Ask each supplier to show how it would handle a real line stoppage at your factory, including who pays for labor, travel, and urgent freight.<\/p>\n<h1><\/h1>\n<h1><strong><b>What after-sales service should cover<\/b><\/strong><\/h1>\n<p><iframe loading=\"lazy\" title=\"Client Project Case | CJ-C-2050 Automatic Facial Tissue Production Line\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/aCilxc01cOQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<p>After-sales support spans commissioning, normal operation, breakdown response, and equipment upgrades. A new factory will often place more value on installation support and operator training. A plant upgrading a single wrapper may care more about compatibility, field service availability, and keeping its existing production schedule intact.<\/p>\n<p>Ask suppliers to quote against the same equipment boundary. A toilet roll route may include a rewinder, tail sealer, log accumulator, log saw, wrapper, bundler, and palletizer. A facial tissue route adds different interfaces around folding, stack transfer, cutting, and carton or bag infeed. Each interface can affect output, even if every machine passed a standalone trial.<\/p>\n<p>Separate the warranty remedy for a covered defect from ongoing technical support and paid maintenance. Also identify which party will coordinate troubleshooting when the line includes a third-party machine. In a mixed-supplier project, the buyer may hold that role unless an integrator is expressly assigned it. Name a person or team with authority to convene suppliers and record the next action.<\/p>\n<h1><strong><b>Read the warranty as a scope of work<\/b><\/strong><\/h1>\n<p>Warranty duration is easy to compare. The start date, covered costs, and claim procedure have more bearing on the factory\u2019s experience. Ask the supplier to identify the equipment by model or serial number and describe the remedy for a covered defect. Establish whether a repair, replacement, or return-to-base assessment is expected and who decides between those options.<\/p>\n<table>\n<tbody>\n<tr>\n<td width=\"192\"><strong>Warranty item<\/strong><\/td>\n<td width=\"474\"><strong>What to confirm in writing<\/strong><\/td>\n<\/tr>\n<tr>\n<td width=\"192\">Start and expiry<\/td>\n<td width=\"474\">Shipment, delivery, commissioning, or acceptance trigger; any outside expiry date<\/td>\n<\/tr>\n<tr>\n<td width=\"192\">Parts and modules<\/td>\n<td width=\"474\">Coverage for mechanics, electrical controls, software, and third-party equipment<\/td>\n<\/tr>\n<tr>\n<td width=\"192\">Exclusions<\/td>\n<td width=\"474\">Normal wear, consumables, site conditions, or unauthorized changes; required evidence<\/td>\n<\/tr>\n<tr>\n<td width=\"192\">Labor and logistics<\/td>\n<td width=\"474\">Who pays for diagnosis, installation, travel, freight, duties, and return shipping<\/td>\n<\/tr>\n<tr>\n<td width=\"192\">Claims and replacements<\/td>\n<td width=\"474\">Reporting channel, evidence, dispatch process, and warranty on repaired or replaced parts<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p>Start dates matter in overseas projects. If the warranty begins at shipment but the building or utilities are late, part of the period may pass before the first production run. Discuss how delays are handled and record the trigger and any time cap. If the supplier offers a different start rule for individual components, make it visible in the equipment schedule.<\/p>\n<p>Do the same for wear parts. Log saw blades, perforation components, belts, seals, and knives may have ordinary wear exclusions. Ask how the supplier distinguishes wear from premature failure caused by a manufacturing defect and what evidence it will review. Retain maintenance records, material specifications, and operating logs so a claim can be evaluated on the facts.<\/p>\n<p>For third-party drives, controllers, or packers, clarify whether you submit claims through the line supplier or directly to the component manufacturer. An entitlement to a replacement part does not settle who will identify the correct revision, install it, restore parameters, or verify that the line runs afterward. These items should appear in the service or warranty schedule.<\/p>\n<h1><strong><b>Separate response time from time to restart production<\/b><\/strong><\/h1>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6470\" src=\"http:\/\/dechangyu.com\/wp-content\/uploads\/2026\/05\/IMG_6951.jpg\" alt=\"\u0645\u0639\u0631\u0636 DCY\" width=\"491\" height=\"276\" \/><\/p>\n<p>A 24-hour contact channel can be useful on a night shift. It does not by itself tell you when a qualified engineer will engage or when a line will resume production. A useful service-level agreement, or SLA, defines milestones by incident severity and gives both parties a way to measure them.<\/p>\n<table>\n<tbody>\n<tr>\n<td width=\"192\"><strong>Milestone<\/strong><\/td>\n<td width=\"474\"><strong>What the buyer should record<\/strong><\/td>\n<\/tr>\n<tr>\n<td width=\"192\">Acknowledgment<\/td>\n<td width=\"474\">Case number, time received, severity, and assigned owner<\/td>\n<\/tr>\n<tr>\n<td width=\"192\">Qualified technical engagement<\/td>\n<td width=\"474\">Time a technician able to diagnose the affected system starts work<\/td>\n<\/tr>\n<tr>\n<td width=\"192\">Diagnosis and action plan<\/td>\n<td width=\"474\">Suspected cause, evidence needed, next decision, and update interval<\/td>\n<\/tr>\n<tr>\n<td width=\"192\">Dispatch or field mobilization<\/td>\n<td width=\"474\">Part release and shipment, or technician deployment and estimated arrival<\/td>\n<\/tr>\n<tr>\n<td width=\"192\">Production restoration<\/td>\n<td width=\"474\">Time an agreed product can run within the defined quality and rate limits<\/td>\n<\/tr>\n<tr>\n<td width=\"192\">Case closure<\/td>\n<td width=\"474\">Verified remedy, remaining actions, and a report where required<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p>Define the clock. Does it start when the buyer reports the issue, when the supplier receives a complete incident record, or when business hours begin? Confirm the time zone, weekend and holiday coverage, and conditions for pausing the clock. A supplier may need data, safe access, or a buyer decision to proceed. If so, ask it to record what is outstanding and when the case resumes.<\/p>\n<p>Set severity by operational impact. A complete line stop with no approved alternative calls for a different response than a single format running below target or a request for a manual. Specify who can reclassify a case as impact changes. Ask how often the factory will receive updates while waiting for parts or a field engineer.<\/p>\n<p>Use a restart definition that reflects your business. A machine that jogs successfully has passed an initial check. A wrapper that packs a few samples may still fail at normal speed. For a critical stoppage, restoration can be defined as an agreed run on a representative SKU with acceptable counts, seal quality, reject handling, and stable transfer. Track temporary recovery separately from a permanent corrective action.<\/p>\n<h1><strong><b>Test how the supplier would handle a real incident<\/b><\/strong><\/h1>\n<p>Before placing the order, give shortlisted suppliers the same scenario. For example: on Saturday night, a toilet roll wrapper repeatedly stops, the upstream accumulator fills, and the rewinder can no longer discharge. The HMI shows several alarms from different stations. A similar pack ran successfully the previous day.<\/p>\n<p>Ask the supplier to describe who answers, who reviews the evidence, and who brings in the wrapper specialist. A plausible first step is to compare the order of events and identify whether the wrapper fault preceded the upstream stop. Review the active recipe, pack size, film lot, and recent maintenance. A downstream alarm can be a consequence rather than the cause, so a diagnosis should explain which observations support the next check.<\/p>\n<p>Then ask how the case proceeds if remote diagnosis points to a component that requires replacement. Can the supplier identify it from the machine serial number and as-built parts list? Is a compatible revision already stocked? Who can install and verify it? If the fault sits between machines, which supplier owns coordination until the interface is proven?<\/p>\n<p>The exercise should end with a restart test and a report of what changed. If the supplier proposes a temporary operating restriction, ask how long it can remain in place, who approves it, and what the permanent repair requires. This scenario tests access, parts, escalation, and return to production in one discussion. It also reveals whether a fast acknowledgment is backed by a credible recovery process.<\/p>\n<h1><strong><b>Plan critical spares around actual recovery time<\/b><\/strong><\/h1>\n<p>A useful spare parts plan begins with the installed configuration and the consequence of failure. The same sensor may be easy to replace on one line and difficult to obtain on another because of its connector, firmware, mounting, or approved revision. Ask for a serial-number-specific bill of materials and identify the parts that can stop production even when they rarely fail.<\/p>\n<h2><strong><b>Separate consumables from critical and specialist parts<\/b><\/strong><\/h2>\n<p>Regular-use stock may include blades, belts, filters, seals, or other items the maintenance schedule calls for. Critical spares may include selected sensors, drives, HMI units, or other controls when their failure would stop the route and their replacement lead time exceeds the plant\u2019s tolerance. Specialist items may include custom embossing rolls, shafts, or assemblies that require factory repair or exchange.<\/p>\n<p>For each critical item, record the installed part number and revision, quantity, stocking location, normal and urgent lead times, storage conditions, and replacement skill. If the part is configurable, record the parameter file, engineering tool, license, and version needed to put it back into service. A spare drive on a shelf still leaves a recovery problem if nobody can load the approved parameters.<\/p>\n<h2><strong><b>Compare dispatch with delivery to the plant<\/b><\/strong><\/h2>\n<p>Ask whether a lead time means time to manufacture, time to dispatch from stock, or time to arrive at the factory. For imported parts, order approval, warehouse hours, transport, customs, and final delivery can each add time. Request a named dispatch location and evidence of stock or a replenishment arrangement. Identify who arranges urgent freight and import paperwork, especially for warranty shipments.<\/p>\n<p>Review alternative sourcing and repair options as well. A standard bearing may be locally available if its specification is clear. A substituted encoder, drive, or safety device may require compatibility review and validation. Ask which alternatives the supplier can approve and what documentation it will provide.<\/p>\n<p>Treat the initial spares package as a starting inventory. Set stock levels using failure consequence, consumption, replenishment time, and the availability of a workable alternative. Update the list after the first operating months and after major modifications. Stock ownership and replenishment rules matter more than a one-time list attached to the quotation.<\/p>\n<h1><strong><b>Verify field service in the country of installation<\/b><\/strong><\/h1>\n<p>A regional sales contact and a qualified field technician perform different roles. Ask where engineers are based, which machine families they support, what languages they use, and whether they are employees or authorized partners. Confirm who can handle mechanical work, who can troubleshoot controls, and how additional expertise is brought into the case.<\/p>\n<p>For cross-border projects, separate the time to approve dispatch, the time to mobilize, and the estimated arrival date. Travel, visas, local work permissions, and site access can affect on-site availability. Discuss the options for a qualified local team to perform agreed work with OEM guidance if the original specialist cannot travel promptly.<\/p>\n<p>Request comparable customer references where available. A plant running similar equipment, paper grades, and shifts can explain how breakdowns, training, and spare parts worked in practice. Useful evidence also includes a redacted service report, sample maintenance plan, or example of a parts quotation tied to a serial number.<\/p>\n<p>Ask which costs are included in a field visit. Confirm travel and accommodation, minimum billing, weekend rates, tools, interpreters, and whether diagnosis, repair, or follow-up is charged separately. A support option that looks inexpensive can have a very different cost once mobilization and waiting time are considered.<\/p>\n<h1><strong><b>Build installation and commissioning into the service plan<\/b><\/strong><\/h1>\n<p>Commissioning goes more smoothly when the supplier and factory share the same site-readiness plan. Before shipment, confirm the layout, foundation or floor requirements, incoming power, compressed air, extraction, lifting equipment, access, and material supply. Assign who receives the crates, positions equipment, makes connections, and prepares trial materials. For a retrofit, specify the outage window and when the existing line must return to production.<\/p>\n<h2><strong><b>Agree what factory acceptance will prove<\/b><\/strong><\/h2>\n<p>Factory acceptance testing, or FAT, takes place before shipment. Use it to check the equipment scope, agreed functions, control sequences, and any interfaces that can be tested at the supplier\u2019s facility. Include representative paper grades and products where practical. Record the limits of the setup; for example, the customer\u2019s existing case packer may be unavailable, so the full handoff must be demonstrated later at site.<\/p>\n<p>Write down what counts as a pass. A toilet roll test may include roll width, diameter, usable length, perforation, tail closure, cut quality, and finished pack integrity. A folded tissue test may emphasize sheet count, fold alignment, stack transfer, pack orientation, and dispensing. Include planned duration, count locations, and how normal material replenishment and rejects are treated. Record what the FAT does not cover and carry those items into the site plan.<\/p>\n<h2><strong><b>Use site acceptance to verify the installed route<\/b><\/strong><\/h2>\n<p>Site acceptance testing, or SAT, confirms performance with the installed line, local utilities, operators, paper grades, and packaging materials. Define the sustained good output target for the specified product, the production period, quality limits, and permitted interventions. Count good output at the agreed boundary; running the rewinder at its nominal speed is different from making saleable wrapped packs.<\/p>\n<p>Include normal operating events such as startup, material replenishment, a representative format change, and controlled recovery after an interruption. Decide how the team will handle incomplete items, retesting, and acceptance records. Keep a named owner and due date for each open item, and distinguish what must be resolved before routine operation from what can be completed afterward.<\/p>\n<p>DCY\u2019s <a href=\"https:\/\/dechangyu.com\/ar\/%d8%ae%d8%af%d9%85%d8%a9\/implementation-support\/\"><u>implementation support<\/u><\/a>\u00a0page describes preparation before installation, trial runs, technical training, and access to specialist support. For a specific project, agree the on-site tasks, number of visits, customer responsibilities, and acceptance measures in the proposal.<\/p>\n<h1><strong><b>Check the handover documents and training<\/b><\/strong><\/h1>\n<p>Operators, maintenance technicians, and supervisors need different information. Operator training should cover normal production, product changes, replenishment, inspection, and when to escalate. Maintenance training should explain diagnostics, routine service, approved part replacement, and restoration of settings. Ask the supplier to demonstrate these tasks and give the factory team time to perform them with supervision.<\/p>\n<p>Request as-built documents in an agreed language and format. The minimum package should be tailored to the equipment, but typically includes operating and maintenance manuals, electrical and pneumatic drawings, parts lists, approved recipes or settings, and the records needed to identify installed hardware. Ask for the final revisions after commissioning and a process to keep them current after service work.<\/p>\n<p>For controls, agree what the buyer will receive for the programmable logic controller (PLC), operator interface, drives, and connected devices. There may be valid restrictions on source code or engineering access. Clarify the deliverable backup files, licenses, permissions, and the supplier\u2019s recovery obligations. Ask for a supported restoration procedure and verify who can carry it out if a controller or HMI must be replaced.<\/p>\n<p>Give each shift access to current instructions and the service contact. A common handover failure is training one person during commissioning and assuming the knowledge will transfer automatically. Use shift coverage, competency checks, and a refresher plan to preserve the training as operators and products change.<\/p>\n<h1><strong><b>Set clear rules for remote diagnosis<\/b><\/strong><\/h1>\n<p>Remote support is useful for reviewing alarm history, equipment status, recipes, and faults that can be diagnosed from available records. Other problems require physical inspection, mechanical measurement, or a qualified technician on site. A supplier should explain both the capabilities and the limits of its remote service.<\/p>\n<p>Agree how the factory authorizes a session, identifies the technician, controls access, and records changes. Give diagnostic access only to the systems needed for the case. If a settings or software change is proposed, identify what will be changed, who approves it, how the previous state can be restored, and how production will be verified afterward. Ask the plant\u2019s operational technology team to review the arrangement; <a href=\"https:\/\/csrc.nist.gov\/pubs\/sp\/800\/82\/r3\/final\" rel=\"noopener\"><u>NIST\u2019s operational technology security guide<\/u><\/a>\u00a0explains why reliability and safety matter alongside access control in industrial systems.<\/p>\n<p>Set an alternative process when remote connectivity is unavailable or prohibited. A factory may be able to share an approved alarm export or production log and perform checks with local personnel. Define which records may be shared, how they are transferred, and how the supplier will escalate if remote evidence is insufficient. Remote assistance does not replace local authority over machine access, isolation, or restart.<\/p>\n<h1><strong><b>Prevent repeat failures and plan for obsolescence<\/b><\/strong><\/h1>\n<p>Ask for a maintenance plan organized around the actual modules and production duty. It should identify inspection and replacement intervals or condition limits, required skills, and tasks that need a scheduled outage. On a converting line, recurring checks may include paper dust management, blade and anvil condition, belts and bearings, sensor alignment, pneumatic or vacuum performance, and packaging seal components. Confirm the equipment-specific procedures with the supplier.<\/p>\n<p>Service records should help the plant distinguish one-off failures from repeated loss. Track incidents by asset, SKU, cause, and time awaiting diagnosis, parts, or field support. If a fault returns after a part is replaced, ask for a root cause review and a follow-up check under the original operating conditions. A closure record should separate what was verified from what is still suspected.<\/p>\n<p>For long-lived machinery, ask how the supplier handles discontinued controls and custom mechanical parts. An acceptable replacement may require a new drive, revised wiring, parameter conversion, or software changes. Request an upgrade path, estimate the production interruption, and confirm whether safety and production interfaces need revalidation after the change.<\/p>\n<p>Compare preventive service plans by their actual work. A scheduled inspection, parts forecasting, refresher training, and a documented performance review offer different benefits from an emergency hotline. Decide which tasks the factory can handle internally and where specialist support is worth retaining. Review the arrangement after the line has enough operating history to identify its main losses.<\/p>\n<h1><strong><b>Compare service using the cost of an interruption<\/b><\/strong><\/h1>\n<p>Downtime is most useful as a comparison when the calculation distinguishes output that can be recovered from output that is permanently lost. If a factory can make up an order on a spare shift, value the incremental recovery cost. If an order cannot be recovered, estimate lost contribution margin rather than treating the full sale price as a loss. Include direct repair, freight, restart scrap, and other incremental costs only once.<\/p>\n<h2><strong><b>A worked downtime example<\/b><\/strong><\/h2>\n<p>Assume a packaging constraint stops a line that normally produces 4,000 good packs per hour for six planned production hours. The factory can recover 75 percent of the missed packs on a later shift. The remaining 25 percent represent lost sales at USD 0.12 of contribution per pack. The figures below are illustrative and do not represent a supplier quote or performance guarantee.<\/p>\n<table>\n<tbody>\n<tr>\n<td width=\"328\"><strong>Cost or quantity<\/strong><\/td>\n<td width=\"337\"><strong>Illustrative result<\/strong><\/td>\n<\/tr>\n<tr>\n<td width=\"328\">Missed good packs during the stop<\/td>\n<td width=\"337\">4,000 \u00d7 6 = 24,000 packs<\/td>\n<\/tr>\n<tr>\n<td width=\"328\">Packs recovered on a later shift<\/td>\n<td width=\"337\">18,000 packs<\/td>\n<\/tr>\n<tr>\n<td width=\"328\">Lost contribution on unrecovered packs<\/td>\n<td width=\"337\">6,000 \u00d7 USD 0.12 = USD 720<\/td>\n<\/tr>\n<tr>\n<td width=\"328\">Incremental overtime to recover output<\/td>\n<td width=\"337\">USD 450<\/td>\n<\/tr>\n<tr>\n<td width=\"328\">Expedited freight and restart scrap<\/td>\n<td width=\"337\">USD 300 + USD 120<\/td>\n<\/tr>\n<tr>\n<td width=\"328\">Estimated incremental incident cost<\/td>\n<td width=\"337\">USD 1,590<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p>The example does not charge lost margin on the 18,000 recovered packs. It also leaves out routine costs that would have been incurred without the stop. A local spare or a faster diagnostic handoff might reduce the outage, but estimate that effect from a credible sequence of events. If most of the delay is customs clearance, a shorter acknowledgment target will have limited value by itself.<\/p>\n<p>Apply the same assumptions to each proposal. Compare coverage fees, initial stock, technician rates, and plausible recovery scenarios over a common period. If exact failure frequencies are unknown, show a range rather than a single forecast. Use the result to decide which parts, service options, and response milestones to negotiate.<\/p>\n<h1><strong><b>A buyer scorecard for comparing after-sales service<\/b><\/strong><\/h1>\n<p>Use a scorecard to make suppliers answer the same questions.

A useful schedule identifies covered assets, warranty trigger and expiry, exclusions, agreed service hours, support channels, escalation owners, parts and travel charges, handover deliverables, and the acceptance process. For an integrated line, include a responsibility list for each transfer, control, and safety interface, with one coordinating contact for problems that span suppliers.<\/p>\n<p>Use defined terms. Write whether a time limit covers acknowledgment, engineer engagement, part dispatch, arrival, or verified restart. State which parts are committed stock and which are made to order. Specify whether commissioning and training days are included and what happens if the site or a third-party machine is unavailable during the planned visit.<\/p>\n<p>Align the attachments with the final order. A technical proposal, service brochure, distributor email, and contract may describe different scopes. Ask the supplier to reconcile the differences and identify the controlling project documents.

Share the machine scope, installation country, shift pattern, target SKUs, existing equipment, and critical production risks. If the line must keep supplying customers through a breakdown, explain what recovery time the factory can tolerate and which skills or parts are available locally. This makes it easier to agree on a support arrangement that fits the production plan.<\/p>\n<h1><strong><b>Frequently asked questions<\/b><\/strong><\/h1>\n<h2><strong><b>How long should the warranty be<\/b><\/strong><\/h2>\n<p>Compare warranty periods only after matching the start date, covered equipment, remedies, and costs. A longer period may have less value if it begins long before commissioning or covers parts without labor or freight. Ask suppliers for the proposed terms in writing and consider how they fit your installation schedule.<\/p>\n<h2><strong><b>Does round-the-clock support guarantee same-day repair<\/b><\/strong><\/h2>\n<p>No. A support channel may be available at any time, while repair depends on qualified diagnosis, stock, field access, travel, and validation.

Where a supplier cannot commit to restoration time, clarify which milestones it can commit to and what affects the rest.<\/p>\n<h2><strong><b>Which spare parts should a new tissue factory buy first<\/b><\/strong><\/h2>\n<p>Start with routine consumables and machine-specific items that can stop production and take longer to obtain than the factory can tolerate. Verify the installed revision and stocking location. For programmable parts, include the approved configuration and the tools or specialist needed to restore operation.<\/p>\n<h2><strong><b>Who should handle faults on a line with equipment from different suppliers<\/b><\/strong><\/h2>\n<p>Agree on one coordinating contact and assign each machine and interface before placing the order. The coordinator should gather evidence, bring in the relevant suppliers, and own updates. Each supplier should retain responsibility for its defined work, and a restart test should verify the affected route as a whole.<\/p>\n<h2><strong><b>Can remote support replace a commissioning engineer<\/b><\/strong><\/h2>\n<p>Some preparation, diagnostic review, and training can be done remotely. Physical installation checks, alignment, site interfaces, and certain acceptance or safety tests may need qualified people at the machine. Confirm who will perform those tasks and how they will be documented before relying on a remote-only plan.<\/p>\n<h2><strong><b>What should a factory send when opening a service ticket<\/b><\/strong><\/h2>\n<p>Provide the site and asset identification, symptom, production impact, time and time zone, alarm history, current product and settings, and any recent material or maintenance changes. Include approved photos, video, or log exports where useful. State the safe condition of the machine and name the plant contact who can coordinate access and testing.<\/p>\n<h1><strong><b>Put the recovery plan in writing before the order<\/b><\/strong><\/h1>\n<p>The most useful service proposal shows how the line will be commissioned, how a critical fault will be handled, and how the factory will confirm recovery. Before choosing a supplier, compare the written warranty, ask for parts and field service evidence, and work through a realistic stoppage. Record the agreed responsibilities in the order so production, maintenance, and the supplier have the same plan on the day the line stops.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6468\" src=\"http:\/\/dechangyu.com\/wp-content\/uploads\/2026\/05\/IMG_6939.jpg\" alt=\"\u0645\u0639\u0631\u0636 DCY\" width=\"388\" height=\"218\" \/><\/p>\n<p><strong>Discuss your project with DCY.<\/strong>\u00a0Share your equipment list, installation location, production schedule, and critical service needs through our <a href=\"https:\/\/dechangyu.com\/ar\/%d8%ae%d8%af%d9%85%d8%a9\/solution-proposal\/\"><u>solution proposal service<\/u><\/a>.
