A short RFQ for vacuum laminating equipment can still produce quotes that cannot be compared. Suppliers fill the gaps with their own assumptions, so one quotation covers a roll-to-roll line for large LCD glass and the next covers a small lab chamber, and the purchase team only discovers the mismatch after weeks of email. The fix is not a longer document. It is an RFQ that closes the questions a laminating supplier would otherwise answer for you.
Start with the product, not the machine
The first block of questions defines what enters the machine. State the substrate — glass, flexible OLED, film or a soft-to-hard combination — together with the size range and thickness. Panel size drives chamber volume, roller width and handling, which is why the same supplier will quote very differently for a 5–15 inch touch glass and a large LCD. Provide drawings or a sample part with tolerances for the fitting error you need to hold, and say explicitly whether the surface is flat, curved or 3D. Curved-surface work needs dedicated arc mechanisms and a different alignment approach, so leaving that detail out of the RFQ is one of the most expensive omissions.
Fix the process requirements in writing
Next, list the process conditions the machine has to create: the working vacuum level, working temperature, press pressure and cycle time per piece. These are the figures the supplier sizes pumps, heaters and platens against. If you already have a target yield, or a known defect such as alignment bubbles, say so; the alignment method, recipe handling and vacuum profile are designed around that defect rather than around an average machine. The same applies to automation level. Semi-automatic roller bonding and a fully automatic bonding assembly line are different projects, with different footprint, utility and staffing assumptions, and an RFQ that does not name one will receive both.
Ask how alignment is inspected and corrected
Ask each supplier to answer the same alignment questions: what vision system is used, what alignment accuracy it achieves on your part geometry, and what happens when a part falls outside that window. CCD alignment and a UVW platform are common answers, but the behaviour on out-of-tolerance parts is what determines whether your line absorbs scrap or stops. Record the supplier's answers in one table. A quotation that describes only the hardware cannot be compared with one that specifies correction logic, and the cheapest bidder often looks cheapest only because that question went unanswered.
Cover what a machine quotation usually leaves out
The commercial section should ask for more than a price. Request footprint and utility requirements — power, compressed air, vacuum, gases — so you can check them against your factory before you order. Ask what is included in the machine price and what is carried separately: consumables, tooling, spares, on-site installation and commissioning. Then ask for the acceptance terms in the supplier's own words, including the test used to prove uptime and cycle time, and who pays when those figures are missed. Training, documentation language and response time for support matter as much on a process machine as on the initial discount.
What a supplier needs from you
A precise RFQ shortens the exchange on both sides. Suppliers receiving drawings, target process conditions and required output can quote in one pass, and you receive comparable numbers instead of three different interpretations of the same sentence. If the requirement is not yet that clear, say that in the RFQ and ask for a design review before the quotation.
PowerDe builds semiconductor process equipment, including a vacuum laminating machine range for LCD, OLED and film bonding, plus automatic laminating machine configurations for large displays. Send your drawings, target vacuum, temperature and cycle time, and the team will confirm which configuration matches the process before quoting.
Note: vacuum and temperature figures, fitting accuracy and cycle time differ by model and are set for the part you submit, so treat any number quoted in this article's checklist as a target you must specify, not a machine specification.
