QY-5 Positive Pressure Forming Machine — Dental Thermoformer for Clear Aligners, Retainers & Mouthguards
The step that decides whether an aligner fits.
In aligner production, the forming step is where fit is won or lost. Vacuum formers pull the sheet down with suction alone; the QY-5 uses positive air pressure (2–5 bar inside the chamber) to press the material firmly against every contour of the model. That difference shows up where clinicians feel it: crisp gingival margins, consistent material thickness over the incisal edges, and aligners that seat the way the treatment plan intended.
Built for daily production, not occasional use
The QY-5 uses a rotary structure that shortens each forming cycle — load the sheet, rotate, form, demold — so one operator can work through a full day of cases without the machine becoming the bottleneck. The chamber has a transparent anti-static PC panel, so you can watch the sheet adapt in real time instead of guessing. The aluminum alloy body keeps the machine rigid and stable on the bench, cycle after cycle.
Simple enough for a clinic, capable enough for a lab
A 4.3-inch touchscreen with bilingual Chinese/English interface controls the whole cycle. There are no manual pressure valves to tune and no specialist skills required — most operators are confident after the first session. That makes the QY-5 practical for a chairside in-office aligner setup, and repeatable enough for a laboratory running volume.
Materials and applications
The QY-5 accepts 125 mm round sheets from 0.5 to 6.0 mm thick, in both soft and hard materials — covering the standard PETG/TPU aligner and retainer sheets on the market. Typical applications:
Clear aligners (all stages of a treatment plan)
Retainers (Essix-type)
Sports mouthguards
Before you order — practical points buyers ask about
Air supply is required: the QY-5 needs an external air compressor delivering at least 6 bar (working internal pressure 2–5 bar). Any standard dental compressor that meets this rating will work — ask us if you are unsure about yours, or need a compressor recommendation.
Power: dual-voltage input AC 110 V / 220 V, 50/60 Hz — no transformer needed for most countries.
Footprint: 400 x 305 x 430 mm and 19.5 kg — a true benchtop unit; one person can position it.
Sheets: standard 125 mm round blanks are widely available; we can also supply sheet material with the machine if you want a single shipment.
Support: operation guidance and technical support are provided directly by our team.

SSS
Q: What is the difference between positive pressure and vacuum forming for aligners?
A: Vacuum formers only suck the sheet downward. Positive pressure machines like the QY-5 push the sheet against the model with 2–5 bar of air pressure, producing sharper gingival margins and more consistent material thickness — which directly affects aligner fit and force delivery.
Q: Does the QY-5 need an air compressor?
A: Yes, an external compressor supplying at least 6 bar. Standard dental compressors usually meet this. Contact us if you want a compatible compressor shipped with the machine.
Q: What sheet materials and thicknesses can it form?
A: 125 mm round sheets from 0.5 to 6.0 mm, soft and hard materials — including the common PETG and TPU aligner/retainer sheets.
Q: Is it suitable for a dental clinic without a lab technician?
A: Yes. The bilingual touchscreen and rotary cycle are designed so non-technical staff can run it after a short introduction.
