DTYThe vacuum-forming pull, in one box
A vacuum-forming machine is the compact cousin of thermoforming: heat a sheet, drop it over a mould in the forming box, and pull the trapped air out so atmospheric pressure presses the plastic onto the tool. The whole job is a single, quick evacuation of a fixed box volume to a deep vacuum. Because the box is small and sealed, you do not need huge flow — you need enough displacement to pull it down before the sheet cools, and a deep ultimate vacuum so corners and undercuts form cleanly. A dry oil-free pump handles this without oil changes and keeps the shop clean; an oil-sealed pump earns its place when a very deep, glass-sharp ultimate is the priority.
For prototyping shops, signage makers and small production forming, Yash YBDVP dry pumps give an oil-free deep vacuum with a single service point and no oil disposal. Where the tool needs the last few millibars of ultimate, the ACME oil-sealed pumps step in. Both are ISO 9001:2015 and quoted in 24 hours, sized on box volume and cycle time.

Dry Vacuum Pump (Only Vacuum)
Full range →Oil-free deep vacuum for the forming box — pulls the sheet on undercuts cleanly with no oil to change on the shop floor.
High Vacuum Pump
Full range →Oil-sealed rotary vane for the deepest ultimate vacuum — glass-sharp detail where the tool demands it.
SZESizing note
Match displacement to box volume divided by target pull-down time, then confirm the pump's ultimate vacuum clears your deepest detail. A small vacuum reservoir smooths repeated cycles on a manual machine.
Indicative only — final selection depends on your exact duty point, altitude and air temperature. Send the numbers and an engineer confirms the model.
FAQVacuum Pump for Vacuum Forming Machine — FAQs
- How much vacuum does a small vacuum forming machine need?
- A deep vacuum around −850 mbar or better forms most sheet cleanly. The flow is modest because the forming box is a small sealed volume — you are sizing on how fast you pull that box down, not on continuous throughput. A YBDVP 60 or 100 suits most desktop-to-workshop machines.
- Can I use a dry pump instead of an oil-sealed one for vacuum forming?
- Yes. A dry YBDVP pump reaches the vacuum most forming needs, runs oil-free and has nothing to service beyond the intake filter — ideal for a clean shop. Keep the oil-sealed ACME option only if you form very fine detail that needs the deepest possible ultimate vacuum.
