Vacuum forming plastic absorption process

Vacuum suction forming process is a hot forming process. A method for manufacturing an open shell product using a thermoplastic sheet. The plastic sheet is cut to a certain size and softened by heating. With the help of air pressure difference or mechanical pressure on both sides of the sheet, it is deformed and covered on a specific mold contour surface, cooled and shaped, and trimmed.

Vacuum suction forming this forming method relies on vacuum force to stretch and deform the plate. Vacuum force is easy to realize, master and control, so simple vacuum forming is the earliest and most widely used thermoforming method at present.
