Vacuum Forming Machines.
Heavy gauge sheet-fed vacuum forming machines for structural parts in automotive, aerospace, medical, sanitary, and industrial applications. Custom-built from 1000×600mm to 6000×2200mm forming area, processing sheets from 2mm to 15mm thickness.
What is vacuum forming?
Vacuum forming is a thermoforming process where a heated thermoplastic sheet is stretched over a mold and shaped using vacuum pressure. It produces large structural plastic parts at 70-90% lower tooling costs than injection molding.
The process heats a thermoplastic sheet to 150-200°C using infrared heaters, then uses vacuum pressure (0.8-0.95 bar below atmospheric) to draw the softened sheet against a mold. Machinecraft's PF1-X Series adds a closed chamber with pre-blow bubble formation, achieving wall thickness uniformity within ±10% — significantly better than open-frame machines.
Vacuum forming is ideal for parts ranging from 500mm to over 6,000mm in length, with production volumes from 100 to 50,000 parts per year. Typical applications include automotive body panels, EV components, bathtubs, refrigerator liners, aircraft cabin interiors, medical equipment covers, and agricultural machinery parts.
