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.

Thermoforming with HDPE

High-Density Polyethylene (HDPE) is processed on Machinecraft thermoforming machines at forming temperatures of 140–170°C with sheet gauges ranging from 2mm – 15mm. The material's unique combination of properties makes it suitable for a wide range of industrial applications.

Machinecraft's servo-driven vacuum forming machines provide the precise temperature control, uniform heating, and programmable forming profiles required to achieve optimal results with HDPE sheets. Our machines' closed-chamber design ensures consistent part quality across production runs, while the motorized aperture and multi-zone heating systems accommodate the specific thermal characteristics of HDPE.

Industries that commonly use thermoformed HDPE components include Automotive, Construction, Agriculture, Industrial. Each industry benefits from the material's specific properties — whether that's impact resistance for automotive parts, chemical resistance for industrial enclosures, or surface quality for consumer-facing products.
