Vacuum Forming is the leading plastic Thermoforming process in which sheet plastic is heated and formed over a mold by removing air from the area between, the mold surface and the sheet. Molds can be created from aluminum, wood, or epoxy. The mold type is only dependent on the finished product design requirements. Vacuum forming is a one-sided process. The finished part will have shape and detail on one side.

APPLICATIONS
Use pressure forming when the part will be the "face" of the product expecting a long life. You can pressure form a company logo or model designation with styling lines, surface texture or other
features in a light weight and durable part. Use pressure forming when you have undercuts or rims and a greater depth of draw.
Pressure forming competes with injection molding in terms of surface detail where sharpness and crispness of styling lines and logos is important. It has much more affordable tooling with a shorter time-to-market with easier updates and modifications.
Pressure forming
produce a seamless part and create a stronger structure so you end up with a lighter, cheaper component.
