Why non-standard projects need a different review checklist
A standard machine has a datasheet, a known footprint and a delivery date. A non-standard automation project has none of these at the start. The equipment is designed around your product, your takt time and your floor layout, which is exactly why so many projects stall after the contract is signed: the buyer and the builder agreed on a machine name, not on a working definition.
Before capacity is scaled — one line becomes several, or a prototype becomes production — the following items should be reviewed and written down. They decide whether the project repeats cleanly or is engineered again from scratch.
1. A written process definition, not a product name
Start with the operation the machine must perform, stated in measurable terms: what goes in, what comes out, what has to be removed, bonded, coated, aligned or cleaned, and what "done" looks like. A request such as "we need a cleaning machine" or "we need a laminating machine" can describe two completely different projects.
Write down the workpiece variants that exist today and the ones you expect in the next few years. Scaling usually means new variants, and a machine specified for one part geometry will not absorb another without rework.
2. The physical constraints of your site
Non-standard equipment has to live where you work. Review door widths, ceiling height, floor loading, aisle geometry, and whether the process happens indoors or outdoors. PowerDe's driving-style steam cleaning machines are described for indoor garages and narrow outdoor parking spaces, while the hand-pushed units are moved by an operator. Those are different site profiles, and the choice is fixed by the building, not by preference.
Also confirm the utilities you can actually supply at the position: voltage available on the line, water inlet and drainage, compressed air, and for process equipment the environment control required — nitrogen chambers, glove boxes and vacuum supply all change the layout and the cost.
3. Specification values you can verify on delivery
Ask for a specification sheet whose numbers can be measured in front of you. For a cleaning machine this means steam temperature, vapor pressure, heating power, tank capacity and machine dimensions. For bonding or coating equipment it means alignment accuracy, working temperature, vacuum level, press pressure and cycle time. PowerDe's Fixed Steam Cleaning Machine PowerDe HW02 detail page publishes values of this kind, including a 6 kW heating power, 160°C steam temperature and 0.8 MPa vapor pressure.
Two cautions matter at this stage. First, if the product title and the parameter block on a supplier page disagree, resolve it in writing before order placement. Second, request the parameters that are missing, not only the ones printed: for many models, running time, hose and wand lengths, weight and accessory contents are not published, and these drive day-to-day usability.
4. Your real production rhythm
Scaling is a capacity question, so review the cycle as it actually runs: takt time, changeover time between products, the number of operators the station needs, and how the equipment is fed and unloaded. A machine that meets the cycle time but requires a long changeover will not scale across multiple product families.
Ask what the supplier measured during the prototype or trial, and on which material and part size. Where a supplier quotes uptime or cycle time, confirm the test condition behind it before it becomes your acceptance criterion.
5. Protection functions and safety review
Non-standard equipment is operated by people who did not design it. Review which protective functions are built in and how they are demonstrated at handover. PowerDe's cleaning machines list leakage, short-circuit, high-temperature, high-voltage and water-shortage protection across their pages, and the fixed units run on 220 V mains while mobile units run on battery. Which protection exists on which model should be confirmed per model rather than assumed from a series name.
6. Cleanability and maintenance access
An automation cell accumulates grease, cutting fluid, dust and process residue, and it has to be cleaned without disassembly. Review what can be reached, whether the machine tolerates steam or wash-down, and which parts are consumables. This is where production-line cleaning is planned in rather than improvised: industrial steam cleaning equipment and dry-steam methods remove oil and grease with far less water than a hose, which matters inside a plant with electrical equipment and floors that must stay usable.
7. Documentation and change control
A project that scales is one whose design is repeatable. Before scaling, require the drawing set and revision history, the bill of materials with brand and model for purchased components, the PLC and vision program with a backup, the wiring diagrams, and the assembly and adjustment notes. If the second unit is built from an engineer's memory, the first unit's cost is paid twice.
Agree who raises change requests, who prices them, and what happens to the price of unit two, three and four once unit one is accepted. Change control is where non-standard projects lose their margin.
8. Acceptance criteria agreed before build starts
Write the acceptance test as a document both sides sign: the sample parts, the number of consecutive cycles, the measured values that pass, the visual and functional criteria, and the treatment of any item that fails. For cleaning tasks this includes the soil being removed and the surface it is on — engine compartments, machine tool housings or production-line frames each need a different method and nozzle set-up.
9. Supplier capability and the engineering path
Scaling is an engineering workload, not a purchase order. Review whether the supplier has an in-house team that carries the design through production, and whether they support the step before the machine: prototyping, testing and development. Non-standard automation equipment work and integrated engineering team services matter most when your product is still changing. Shenzhen PowerDe Automation Precision Equipment also lists product development, hardware testing and manufacturing automation as services, which is how a concept reaches a buildable machine.
Ask how many engineers are assigned to your project, who owns the mechanical, electrical and software content, and what the response is when the line stops.
10. Spares, service and the cost of standing still
Review the consumable list, the lead time for wear parts, and whether purchased components are standard items available locally or single-source imports. Confirm the service route: remote support, on-site attendance, and the guaranteed response window. A second machine doubles the maintenance load, so the spare-part plan is settled before the second order is placed.
A short review list to take into the meeting
- Process defined in measurable terms, including future part variants
- Site constraints: access, floor, utilities, indoor or outdoor use
- Verifiable specification values, and every missing parameter requested in writing
- Takt time, changeover and operator count measured on your side
- Protection functions confirmed per model, with the safety review documented
- Cleaning and maintenance access planned into the cell
- Documentation set and change-control rules agreed
- Acceptance test signed before build starts
- Engineering ownership and capability for repeat units
- Spares, lead times and response window agreed
Send the definition, not the machine name
If you are preparing a scaling decision, send the process definition, the workpiece data, the site constraints and the parameters you need verified, and ask the supplier to confirm each one for the specific model. That single document moves the discussion from a catalogue to a design, and it is what makes the second, third and fourth machine cheaper than the first.
You can review equipment options in the PowerDe product catalogue or describe your process through the contact page.
