Vacuum Forming |
|
Vacuum forming is the process of heating a sheet of plastic and using vacuum and pressure to form the part into the shape of the tool. Typically, with vacuum forming, the mold side of the part is, in most cases,
non-cosmetic so you are using the textured sheet for the aesthetics of the part. In other words, the sheet provides the cosmetics. There are multiple textures to choose from as well as colors. WPS does custom and
generic colors, which allows us to match your color scheme.
Some advantages of using the vacuum forming process over other plastic processes are cost effectiveness, shorter lead times, and reduced part weight. Therefore, vacuum forming is more conducive in allowing for more
frequency updating of our customer's designs.

Pressure Forming |
|
Pressure forming is similar to vacuum forming, however, you get the cosmetics appearance of an injection-molded part. This process uses female tools with the texture already on the tool, which allows you to have
multiple textures or smooth areas on the same part. The sheet is heated to forming temperature, the hot sheet is transferred to the forming station, the molds are brought together and pressure is applied to the
tools forcing the material against the mold surface so the texture of the tools is transferred to the final part.
This process is best suited for parts are used in the electronics, medical, healthcare, industrial and many other industries.
The major advantage of pressure forming is that you get the cosmetics from the tool. This allows the economical production of large parts with cosmetics that match those of injection-molded parts, or other
materials with a far more competitive investment in tooling costs.

Twin-Sheet Forming |
|
Synchronized forming of two sheets using matching cavity molds fuses the two halves of a part together instantaneously during the process, resulting in one product with hollow regions (such as an external panel
and interior liner with multiple recesses and complex modern styling). Foam can be injected after the process to enhance the insulation, floatation and structural properties of the finished part or component.
Some advantages of twin-sheet forming are that the parts produced are structurally sound and you can produce hollow parts without secondary bonding. The twin sheet process can produce parts similar to rotational
and blow molding.
