OVERVIEW of Plastic Vacuum Forming |
Vacuum forming (also known as thermoforming or pressure-forming) is a way to make thin plastic products by heating a plastic sheet until it is soft, then lowering the plastic sheet over a pattern at the same time the air is withdrawn from between the plastic and the pattern. When the air is withdrawn, a vacuum is created, and the plastic sheet is pressed to the pattern by atmospheric pressure. Vacuum forming typically makes "one-sided" or "shell" type parts.
During the vacuum forming process, a sheet of heated plastic material is placed over a male or female mold. The mold then moves towards the sheet and presses against it to create a seal. Next, the application of a vacuum draws out the air between the mold and the sheet so that the plastic conforms to the mold exactly. This is accomplished through venting holes in the mold that are joined to vacuum lines. The mold also has a water cooling system integrated into it that brings the temperature of the plastic to the set temperature needed. When the curing temperature is reached and the piece is formed, air blows back into the mold and separates the new part from the mold.
Vacuum forming services produce plastic parts for various industries, such as the food, cosmetic, medical, electronics, entertainment, household products, toys, athletic equipment, appliance, automotive, office supplies and clothing industries.
