Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product.

Pressure forming is commonly used on parts with lots of detail.  This is because the downward pressure into the part is about 5 times higher than what you can attain with thermoforming.  This additional pressure moves the material into the more detailed areas. The part detail appears sharper than injection molding.

The sheet is heated in an oven to a high-enough temperature that it can be stretched into or onto a mold and cooled to a finished shape.Thermoformed and Pressure parts typically replace curved or shaped sheet metal parts that require excessive welding and/or finishing. It is also ideal for replacing fiberglass and wood.

CHawk Technology has the capability of vacuum forming, pressure forming and drape forming with sizes up to a full sheet (48″ x 120″) and a maximum draw of 24″ deep.
