Process comparison
Vacuum forming vs Pressure forming
Both draw a heated sheet onto a tool. Vacuum forming uses vacuum alone; pressure forming adds compressed air on the back of the sheet to press it harder into the tool for sharper detail.
Vacuum forming vs Pressure forming — side by side
| Vacuum forming | Pressure forming | |
|---|---|---|
| Forming force | Vacuum only | Vacuum + compressed air |
| Detail / sharpness | Good | Excellent — near injection-moulded |
| Formed-in texture | Limited | Yes — crisp texture and logos |
| Tooling cost | Lowest | Slightly higher (pressure box) |
| Typical use | Trays, liners, covers | Cosmetic housings, panels, detailed parts |
Choose Vacuum forming when…
- Trays, liners and general covers
- Lowest tooling cost
- Detail requirements are moderate
Choose Pressure forming when…
- Sharp edges, fine detail and formed-in texture
- Cosmetic Class-A housings and panels
- Injection-mould look at thermoforming cost
The verdict: Vacuum forming is the economical default; pressure forming is the upgrade when a part needs crisp detail, sharp edges or formed-in texture. We run both and pick per part.
Frequently asked
When is pressure forming worth it?
When the part is cosmetic or needs sharp edges, fine features or formed-in texture — pressure forming gives an injection-moulded look at a fraction of the tooling cost.
