MUSI After-Sales System
many years of industry experience has taught us that after-sales quality matters as much as equipment performance. A single equipment failure can cost a customer $10,000+ per day in lost production. Therefore, rapid response and efficient resolution are at the core of our after-sales service.
MUSI has established a three-tier after-sales system: Customer Service Center + Global Service Network + Factory Technical Support — providing comprehensive support for stable line operation worldwide.

?Warranty, spare parts and service coverage questions
What does the warranty exclude, and what is the buyer responsible for?
Consumables such as seals, filters and heating elements are covered for 6 months under normal use instead of the 12-month full-machine term. Failures caused by misuse are not covered; out-of-warranty and misuse-related repairs are charged at material cost plus the engineer's travel expenses at actual cost; the technical service itself is free. The buyer is responsible for operation and daily maintenance as trained. The final terms are those written in the contract.
When does the warranty start, and how are open commissioning items handled?
The warranty runs from acceptance: 12 months for the full machine, 36 months for critical components (motors, drives, PLC) and 60 months for structural parts (steel structure, ducts, oven body). Acceptance is signed after equipment, line and capacity acceptance pass, so any open item should be listed with an owner and a re-test date before sign-off rather than left undocumented.
Which critical spare parts should we keep at our factory?
Start from the equipment parts list and your downtime risk: electrical parts (contactor, breaker, PLC module, drive, sensor), mechanical parts (chain links, bearings, seals), spray parts (gun nozzles, electrodes, powder hoses) and filters. MUSI prepares a customised parts list. Spare parts ship from the Changzhou headquarters with same-day shipping available, and customers can set up a dedicated parts stockroom at MUSI for emergencies.
How do we order a replacement part and confirm it fits our line?
Send the equipment model and serial number, the part number or a nameplate photo, and the control version where relevant. Compatibility is checked before quoting, and the quotation states whether the part is the original or an approved alternative; for critical or safety-related parts, compare specifications and confirm in writing before fitting.
What happens if our overseas line stops during a production shift?
Report it by phone or WhatsApp on +86 181 5173 1332 (24-hour emergency line) or by email to lin@coating-spray.com with the equipment model and fault description. The technical team gives a preliminary diagnosis within 2 hours; if on-site service is needed, the nearest service partner is assigned and engineers arrive at any major city within 72 hours. Each case closes with customer sign-off and a 7-day follow-up.
How do we check service coverage in our country before ordering?
MUSI has authorised service partners in Vietnam, Thailand, Indonesia, the Philippines, India, Malaysia, the UAE, Saudi Arabia, South Africa, Egypt, Mexico and Brazil. Elsewhere, support comes from the Changzhou headquarters by phone and video, with engineers dispatched for on-site work. Ask which partner or team would cover your site and write the response arrangement into the contract; a trained in-house maintenance team reduces dependence on travel.
Should we sign an annual service contract or maintain the line ourselves?
Compare your team’s skills, the preventive inspection workload, spare parts, travel and the cost of downtime. MUSI offers annual maintenance contracts with periodic preventive inspections, free maintenance training and refresher training up to twice a year, so many plants combine in-house daily maintenance with an annual inspection.
QQuestions buyers ask before ordering
quotation · price · lead time · installation · warranty
What information do you need to prepare a quotation?
Send part drawings or photos, the largest part size and weight, the material, the required output per shift, the paint or powder type and number of colours, and the available floor space, ceiling height and power or gas supply. MUSI engineers reply within 24 hours; a recommended configuration and quotation follow once your part data is complete.
How much does this equipment cost?
Budget depends on part size, throughput and the level of automation. Indicative ex-works ranges are published in our complete coating line cost guide; a configured quotation is prepared from your part data. Published indicative ex-works ranges: a complete powder coating line is roughly USD 75,000–230,000 semi-automatic, USD 200,000–600,000 for a standard automatic line and USD 600,000–2,000,000 for a high-throughput automated plant.
What is the lead time?
Standard configurations ship in 30–60 days from contract signing and down payment; custom configurations take longer. The delivery date is fixed in the contract.
Do you install and train operators overseas?
Yes. MUSI engineers carry out on-site installation and commissioning and give 3–5 days of operator and maintenance training. MUSI has delivered 800+ coating lines to customers in 36 countries.
What warranty and after-sales support are included?
12 months full-machine warranty, 36 months on critical components and up to 60 months on structural parts. International customers get 24-hour phone response and 72-hour on-site arrival; spare parts ship from the Changzhou headquarters.
Can the environmental equipment be supplied with the line?
Yes. VOC treatment (RTO, RCO, activated carbon, zeolite rotor), dust collection and paint wastewater treatment are supplied with the coating line under one contract; MUSI has equipped 50+ coating facilities whose projects all passed local environmental compliance reviews.
