When a component maker, equipment builder, or industrial operator reaches the point where off-the-shelf hardware no longer fits the process, the question is rarely “can we find a supplier?” It is “can we find an engineering partner who can take a functional requirement and turn it into a machine that runs on a production floor?” That distinction matters, because the partner you choose shapes your bill of materials, your qualification timeline, and how much engineering knowledge you keep in-house afterwards.
Shenzhen PowerDe Automation Precision Equipment Co., Ltd., founded in 2007, works on exactly this kind of work: automated production line solutions, non-standard automation equipment, and intelligent cleaning equipment manufacturing alongside semiconductor and thin-film process equipment. The evaluation criteria below are drawn from what a buyer can actually verify before signing, not from supplier marketing.
1. Does the partner already build in your process family?
The fastest way to misjudge a development project is to assume that “automation experience” transfers freely. A line that applies optical film to a flat glass panel and a line that removes cured grease from a machine enclosure share almost nothing: the tolerance stack, the handling of the workpiece, the cleaning steps, and the failure modes all differ.
Ask for the partner’s equipment list in your process family and check whether the models are published with real parameters. PowerDe’s catalogue, for example, publishes model-level data rather than only category names. The PowerDe HW02 steam cleaner is documented with 6 kW heating power, 160 °C steam temperature, 0.8 MPa vapour pressure, an 80 L SUS304 tank, and a 220 V supply. In the display-bonding range, published figures include a fitting error of ≤0.2 mm on membrane-electrode hot press bonding machines and CCD alignment with roller bonding on automatic laminating machines. Numbers like these are what you compare against your own process window, and a partner who will not state them is a partner who has not finished thinking about the design.
2. Is the partner a manufacturer or a broker?
For non-standard equipment, the difference between an integrator with its own fabrication and a trading intermediary shows up in change orders. When a fixture has to be re-machined after the first trial run, an in-house shop turns that around in days; a broker turns it into a purchase request and a queue.
Verify this directly: ask which machining, sheet-metal, welding, and assembly steps the partner performs themselves, and which they subcontract. Then ask who signs the acceptance criteria for the subcontracted steps. A credible partner will also let you audit a running machine in a comparable application rather than only a demo cell. PowerDe’s stated scope covers equipment R&D and manufacturing, system integration, customized configuration, and technical support under one organisation, which is the structure you want when the schedule is being defended.
3. Who is doing the engineering, and at what ratio?
A development project stalls when the supplier’s drawing office is one engineer wide and shared with after-sales firefighting. Ask for the headcount assigned to your programme by discipline: mechanical, electrical and control, software, and process. Ask how many such programmes the same team runs at once.
A high share of technical staff in the supplier’s total headcount is a useful signal for capability, but do not use a supplier’s published percentage as a contractual guarantee — ask instead for the named engineers, their previous projects in your process family, and whether they stay on the programme through commissioning. Where a supplier’s own site quotes different figures for patents or staff, treat them as marketing numbers and get the specific claims you care about confirmed in writing before they influence your decision.
4. How does the partner move from a specification to a qualified machine?
Ask the partner to walk you through a completed project end to end, and listen for the gates:
- A written input specification from you — cycle time, workpiece tolerances, utilities available at the plant, ambient conditions, and what “clean” or “aligned” means in measurable terms.
- A concept review with at least one rejected alternative and the reason it was rejected, so you can see the tradeoffs the partner made rather than only the conclusion.
- A test plan before fabrication: what is measured, with what instrument, against what limit. PowerDe lists hardware testing and product development as separate services, which is a sign that verification is scoped as its own work package instead of being folded into assembly.
- A FAT (factory acceptance test) you witness at the supplier’s works, with the pass criteria agreed before build, plus a SAT (site acceptance test) with your own material.
- A documentation set you can actually service from: electrical drawings, spare-parts list with manufacturer part numbers, control software backup, and a maintenance interval schedule.
If a partner cannot describe these gates in your terms, they are selling you a machine, not an engineering outcome.
5. Does the partner design for the safety and utility reality of your plant?
Process equipment is where protection functions decide whether a line runs at all. Published protection features are a reasonable starting point: PowerDe’s mobile cleaning machines list leakage, short-circuit, high-temperature, high-voltage and water-shortage protection, with the fixed models adding high-voltage explosion protection. Read those as design intent, then confirm what is actually fitted on the configuration you buy and which standards it is built to.
Do the same with utilities. The HW02 is specified for a 220 V supply with a tap-water inlet using a 4-point internal-tooth joint (1/2 inch); the hand-pushed HMW3 runs on a 48 V battery with a 4.5 kW PTC semiconductor heater and a 50 L clean-water tank. Those details determine whether you need a transformer, a water treatment step, compressed air, or a battery charging bay. Send your plant’s utility sheet with your enquiry and require the partner to confirm compatibility in the proposal.
6. What does the contract say about your IP and your exit?
Before any drawing is exchanged, settle four points in writing: ownership of the design files and control code produced for your project; whether the partner may reuse your product’s fixtures or process parameters for another customer; what happens if the partner’s company changes hands; and what you are entitled to receive if you later move production to a second machine or a second supplier. A partner who resists these terms is telling you something useful at a low cost.
7. Can the partner scale from one machine to a line — and back down again?
Many development projects start as a single cell and end as a line, or the reverse: a full-line budget gets cut to one station. Ask how the partner phases delivery, what in the first machine’s design is deliberately kept reusable, and what has to be redesigned if capacity doubles. Where the partner genuinely does both single machines and full lines — PowerDe lists an Industry 4.0 demonstration factory alongside standalone equipment — ask for the phasing plan rather than accepting a capability claim.
A practical shortlist check
Before the first commercial meeting, send each candidate the same three-page package: your functional specification, your utility sheet, and your acceptance criteria with measurable limits. Score the responses on four things you can see in the reply itself — whether the parameters are stated rather than described, whether the proposed test method is named, whether the assumptions are written down and flagged, and whether anyone from the design team, not only sales, attends the follow-up call. A supplier that answers that package competently will usually run the project competently too.
If your requirement sits in cleaning, automation, or a hybrid cell that has to be designed rather than configured, you can put that specification to PowerDe’s engineering team through their contact page and compare the answer against the criteria above. The winning partner is the one whose proposal you can audit — parameter by parameter, gate by gate — before you commit the tooling budget.
