The product page for this series describes it as specialized equipment for the research and development of perovskite solar cells, OLED, lithium batteries, quantum dot LEDs, and OPV. That sentence matters before any integration question is asked, because it describes a different role from the one a production line assigns. An R&D tool has to prove it can coat. A station in a line has to receive material from a supplier, hand work to the next station, take utilities from a building, and be judged by people who did not choose it. The machine does not change between those two roles. The obligations around it do.
The practical consequence is that the confirmations before integration cannot all be sent to the machine vendor. Each boundary the coater touches has a different party who can answer for it, and the usual failure mode is not that a question goes unasked but that it is asked of the wrong party, after which everyone walks away assuming someone else owns the boundary. The sections below walk each boundary and name the party that has to answer.
Read what the page actually says before you write the scope
The first confirmation is internal, and it costs nothing. The slit coating equipment page describes the process plainly: coating liquid is pressed along the gaps of a mold under a certain pressure and transferred to a moving substrate. It lists the reasons the technology is adopted, which are fast coating speed, good coating uniformity, and a wide coating window, and it lists an operating envelope: speeds set from 1 to 10 meters per minute and coating thickness from 5 to 200 micrometers.
Before asking anyone else anything, write one page that states what this station is for: which material system it will coat (the page spans five application fields; a production line runs one or two), what substrate or web it will receive, what output the line expects, and who will judge the coated result. Then test that duty statement against the published envelope. If your ink needs a drying time that a one-meter oven cannot provide at your line speed, or your web is wider than the machine's true coating width, no vendor answer will fix the mismatch later. The scope page is the document every later question is answered against. Teams that skip it end up negotiating with three vendors about a requirement nobody wrote down.
Ask the machine vendor about ink, not about the machine
The description says the liquid is pushed through the die gap "under a certain pressure," and the specification table carries a row reading "Equipment pressure: 6 kg/cm." As written, that unit cannot be parsed, because a pressure per unit of length is not a pressure, and it is not clear whether the row refers to the pump feeding the die, the air system, or something else. Ask in writing: which pressure the row describes, where it is measured, what range is available, and what it implies for ink preparation. The ink-supply questions follow from that answer: whether the ink must be degassed before the pump, what viscosity range the feed system handles, and whether temperature control at the die is included or is yours to provide.
The same conversation should fix the delivery scope: which parts of the ink path, meaning the supply pump, filters, die, cleaning fixtures, and spare seals, arrive with the machine, and which you are expected to install. Scope gaps are rarely argued about before delivery. After delivery they become change orders, and a change order written after the floor plan is frozen costs more than the same question asked before.
Ask your material supplier what the web actually arrives on
The specification table lists a 3-inch inflatable shaft as the retractable device. A core size is a physical constraint that lives in your supply chain, not in the machine: does your incoming roll material arrive on 3-inch cores? If your supplier ships on 6-inch cores, or the trial rolls from your ink supplier come on 1-inch, someone owns a re-spooling step, and that step has a cost, a contamination risk, and a person responsible for it. Ask your material supplier what cores they ship, and ask the machine vendor what the shaft actually accepts.
The coating width row reads "50-350M," which cannot be parsed as written; confirm the usable width in millimeters before you commit a web width to the line. Tension control, braking, and splice handling are not listed on the page. Ask the vendor what exists on the machine, then ask your material supplier what your web can tolerate. A one-off trial forgives a mismatch between core, width, and tension. A production line inherits every mismatch, every day, at full speed.
Ask whoever supplies the oven about your drying curve
The page lists electric heating and an oven length of "1 meter," followed by an unexplained note in parentheses ("Hui Xing"). Two things need closing here. First, if that note names a different manufacturer for the oven, then a third party exists on your acceptance: you are now managing a boundary between two vendors' equipment, and neither one alone can sign for the result. Ask in writing who supplies the oven and who supports it after delivery.
Second, treat line speed and oven length as one calculation rather than two specification rows. At the upper end of the listed 1 to 10 meters per minute, a one-meter oven gives the wet film seconds; at the lower end, about a minute. Whether your ink's drying or curing profile fits inside that window is a question the coater vendor cannot answer without your ink data, and the oven vendor cannot answer without your line speed. Request in writing:
- The oven type and the number of temperature zones.
- The temperature range and control accuracy, and how uniformity across the web is verified.
- How the drying profile is recorded during a run, and in what format you receive it.
- Whether the profile can be adjusted after acceptance, and what that affects.
Confirm the room with your own facilities people
The page gives a machine outline of 2540 x 800 x 1650 mm. An outline is not the space a machine needs. Measure the real route the machine will travel on delivery, meaning door widths, elevator dimensions, turning spaces, and floor loading, and then measure the space it needs in service: clearance to reach the die, to change the shaft, and to refill and maintain the feed path. A room that fits the outline exactly will run the machine with its access panels contested and its maintenance deferred.
The page does not list the machine's installed electrical load, compressed air demand, or exhaust requirements. Request those in writing before the layout is frozen, because utilities are the category of confirmation that becomes more expensive with time: a circuit discovered after the floor is poured is not a purchase, it is construction. Name your own electrician and facilities lead as the people who must sign off on the utility answers. The machine vendor can state what the machine needs; only your people can state what the building can give.
Confirm the signal boundary with the neighboring stations
The specification table lists a three-color warning light as the fault prompt. On a standalone machine that is enough: someone sees the light and reacts. A line changes the question. What does each color mean? Is the fault recorded, timestamped, and exportable, or does it vanish when the light goes off? Can the machine exchange start, stop, and fault signals with the equipment upstream and downstream, or does a human carry the message? Are recipes and run data recorded per web, and in what format?
The downstream side of this boundary is concrete. The perovskite production line equipment page on this site lists the substrate sizes that machine accepts; if it is your next station, its list is the boundary your coated output has to satisfy. And one decision belongs to operations rather than to any vendor: when the coater faults, who has the authority to stop the line, and what happens to the material already between the stations. Write that rule down before the first production week, because the first production week will test it under pressure.
Confirm the definition of a good film with the people downstream
The page states a product pass rate of at least 99.5%. There is no defect definition attached to that figure and no measurement method given. The description also cites good coating uniformity as a reason the technology is used, but the page does not say how uniformity is measured. These are not oversights to argue about. They are the two definitions your line will need and the page does not supply.
Before integration, sit down with the quality engineer and the operator of the next station and agree in writing on four things: what counts as a defect, which is a thickness deviation outside what downstream tolerates, a visible stripe, or a contamination event; where and how thickness and uniformity are measured, and with what instrument; who performs the measurement; and what happens to a failed web, meaning stop, mark, rework, or scrap. A pass-rate figure that two parties cannot reproduce is an argument, not an acceptance criterion. The definition that survives contact with a production line is the one the downstream station helped write.
Close each confirmation with a run, not a meeting
Written answers are the first half. The second half is one run on your own material: your ink, your web, your line speed, with the downstream station judging the output. Write the acceptance language before the run starts, meaning what a good result looks like measured the way you agreed to measure it, and include the changeover in the timing, because changeover is where a line station earns or loses its throughput. Keep fixed reference points and photographs so that a second run can be compared honestly with the first.
Send the record, not the summary, to each party named above. A summary invites reassurance; a record invites answers. If you want the questions this page cannot answer, meaning the pressure row, the width row, the oven note, the utility figures, and the signal options, put in writing, describe your material system and line layout to the PowerDe team through the contact page and ask for written answers before the layout is frozen.
None of these questions is exotic, and almost all of them can be closed within a week of writing. What makes them hard is that no single party holds all the answers. The machine is the part that arrives on a truck. The boundaries are the part you build, and they are built from answers given by several different parties, only one of whom sold you the equipment. Integration is confirmed when every boundary has a named owner, a written answer, and one run on your own material that both sides agreed how to judge before it started.
