1. What exactly is covered after commissioning, and for how long
Ask the supplier to define the warranty period in calendar time and in operating hours, and to state when the clock starts — at shipment, at arrival, or at final acceptance. Those three dates can differ by months. Also ask which parts are consumables: heating elements, seals, vacuum seals, and press platens wear differently, and a warranty that quietly excludes them is narrower than it looks.
Request the response commitment in writing: how fast an engineer replies, how fast a spare part ships, and whether an on-site visit is included. For an overseas buyer, “we will send a technician” means little without a stated timeframe and a note on who pays travel.
2. How the machine is installed, commissioned, and handed over
Ask whether installation and commissioning are remote, on-site, or both, and what your team must prepare beforehand: floor space, power supply, compressed air, vacuum supply, and utility connections. A clear site-readiness list prevents a machine that sits crated for weeks.
Then ask what acceptance actually means. A good handover includes a documented run to the stated process conditions, an agreed set of trial pieces, and a written acceptance record signed by both sides. That record is what protects you if performance is disputed later.
3. Spare parts: what to stock and how fast they arrive
Ask the supplier for a recommended spare-parts list with part numbers and expected service life, split into items you should keep on site and items you can order when needed. Ask whether parts are standard items or supplier-specific, because proprietary parts with a long lead time can stop a line for weeks.
Confirm how long the supplier guarantees availability of that part. R&D equipment is often in service for many years, and a machine whose parts are discontinued after three becomes a repair problem.
4. Training and process support, not just repair support
Ask who trains your operators and technicians, how long the training lasts, and whether it covers fault diagnosis and routine maintenance rather than normal operation only. Then ask about process support: when you change membrane, gasket, or substrate, can the supplier help you re-tune temperature, pressure, cycle, and alignment settings, or is that your problem alone?
Equipment that only gets repaired and never tuned is hard to keep at yield. Ask whether remote adjustment and process consultation are part of the support package and whether they are charged.
5. Documentation and service records
Ask to see the manual language, the electrical and pneumatic drawings, the PLC or HMI documentation, and the maintenance schedule before the machine ships. Ask which drawings you own outright. If you later need a third party to service the equipment, missing documentation is what makes that impossible or expensive.
It is also worth asking how the supplier keeps its own service records for the machine. A supplier with a file on your equipment diagnoses faster than one starting from scratch.
6. Upgrades, retrofits, and future capacity
A hot press bought today for R&D may be needed for production in two years. Ask whether the platform can be upgraded — higher throughput, larger format, added alignment or handling — and roughly what a retrofit costs. Ask the same about the line around it. Our membrane electrode hot press bonding machine sits in a wider thin-film equipment range alongside vacuum hot pressing and multi-layer automatic bonding lines, which matters when you are planning a move from lab to line rather than buying one box.
7. Support from a manufacturer, not a reseller
Ask who actually builds the machine and who holds the design. Shenzhen PowerDe Automation Precision Equipment Co., Ltd. has been building automation and precision equipment in Shenzhen since 2007, with in-house research, manufacturing, and an engineering team that takes on customized configurations — Shenzhen PowerDe Automation Precision Equipment handles the design work directly rather than passing it on.
That matters for support because process questions and spare-part questions reach the people who made the drawings. If your application is unusual, ask about customization and testing before ordering; our hardware testing and engineering services exist for exactly that step.
What to put in the contract
- Warranty start date, duration, and the list of excluded consumables
- Reply time, spare-part shipping time, and on-site service terms including who pays travel
- Site-readiness requirements and a written acceptance procedure with trial-piece criteria
- Spare-parts list with part numbers, prices, lead times, and an availability guarantee period
- Training scope, process-support scope, and what is charged for it
- Ownership of drawings, documentation, and any custom tooling you paid for
If a supplier answers these questions slowly or vaguely, treat that as the answer about what support will be like after delivery. Send us your process requirements and we will state the support terms in writing before you order.
