What is vacuum forming?

Vacuum forming is a thermoforming process where a thermoplastic sheet is heated to a pliable forming temperature, stretched over a mold, and shaped using vacuum pressure. It is one of the most cost-effective methods for producing large plastic parts with relatively low tooling costs compared to injection molding.

What is the difference between vacuum forming and thermoforming?

Thermoforming is the broad category of plastic forming processes that use heat. Vacuum forming is a specific type of thermoforming that uses vacuum pressure to shape heated plastic sheets over a mold. Other thermoforming methods include pressure forming and twin-sheet forming.

What materials can be vacuum formed?

Common vacuum forming materials include ABS, PMMA (acrylic), Polycarbonate (PC), TPO, HDPE, Polystyrene (PS), PET, Polypropylene (PP), PVC, and PLA.

What is heavy gauge vs light gauge thermoforming?

Heavy gauge thermoforming processes cut sheets typically 2-12mm thick for structural parts. Light gauge thermoforming uses thin roll-fed film under 2mm for high-volume packaging. Machinecraft manufactures machines for both.

What industries use vacuum forming machines?

Vacuum forming machines are used across automotive, aerospace, medical, packaging, sanitary, agriculture, signage, and many more industries.

What sizes of vacuum forming machines does Machinecraft manufacture?

Machinecraft manufactures custom vacuum forming machines ranging from 1000x1200mm forming area up to 6000x2200mm (XL).

What is a closed chamber vacuum forming machine?

A closed chamber vacuum forming machine features an air-sealed forming chamber that enables pre-blow bubble formation and zero sag control. This European-concept design is standard on all Machinecraft PF1-X Series machines.

What are the AM-V and AM-P thin gauge roll-fed forming machines?

The Machinecraft AM-V (vacuum forming) and AM-P (pressure forming) are continuous roll-fed forming machines designed for thin gauge packaging, medical trays, and deep draw containers.
