Vacuum Forming & Thermoforming Processes
Advanced plastic manufacturing techniques that shape heated thermoplastic sheets into precise three-dimensional products using vacuum pressure and specialized tooling
Process Introduction
Vacuum forming is an advanced manufacturing process that transforms heated thermoplastic sheets into complex three-dimensional products. The process begins by placing a precisely crafted mold within a semi-automatic forming machine.
A plastic sheet is positioned above the mold and heated until it reaches optimal malleability. The machine then automatically raises the mold, allowing the softened material to conform perfectly to the mold's surface geometry.
A vacuum pump removes air between the mold and sheet, creating negative pressure that ensures complete material contact. Finally, an integrated cooling system solidifies the formed part, enabling clean release from the tooling.

Primary Forming Methods
Positive Molding (Male Mold)
The plastic sheet is drawn over a convex mold form. This method provides excellent dimensional control on the outer surface where the material contacts the mold directly.
- • Superior exterior surface finish
- • Precise outer dimensional control
- • Ideal for decorative applications
Negative Molding (Female Mold)
The plastic sheet is drawn into a concave mold cavity. This approach ensures precise interior dimensions and is preferred for functional components requiring accurate internal geometry.
- • Accurate internal dimensions
- • Better material distribution
- • Suitable for assembly components
