The difference of VACUUM & PRESSURE FORMING

Jun 29, 2019

Thermoforming can use one of two processes, Vacuum Forming or Pressure Forming. Each has its own advantages, and the following will help you decide which process might be right for you.

VACUUM FORMING

DESCRIPTION:
A sheet of plastic material is heated to pliability, then pressed against a 3D mold by vacuuming out the air between the sheet, and the mold.
KEY ADVANTAGES:
1 Cost-Effective
2 Quicker Tooling
3 Ability To Form Very Large Parts

PERFECT FOR:
1 Sharper Details
2 Allows for Undercuts
3 Tighter Tolerances
4 Allows for Molded-In Texture

OFTEN USED TO CREATE:
1 Point-of-Purchase Displays
2 Automotive Aftermarket - Interior/Exterior
3 Recreational Vehicles
4 Pool and Spa
5 Equipment Enclosures, Bezels, Housings and Covers
6 Dunnage Material Handling Trays & Pallets
7 Fitness Equipment

PRESSURE FORMING

DESCRIPTION: 
A sheet of plastic material is heated to pliability, then pressed against a 3D mold by vacuuming out the air between the sheet and the mold, and applying air pressure above the plastic sheet.
KEY ADVANTAGES: 
1 Cost-Effective
2 Quicker Tooling
3 Ability To Form Very Large Parts
PERFECT FOR:
1 Complex Shapes
2 Pieces With Vents or Louvers
3 Projects With Tighter Tolerances
OFTEN USED TO CREATE: 
1 Medical Equipment
2 Office Equipment
3 Vented Equipment Enclosures
4 Control Pads
5 Scientific Instruments
6 Detailed Components
7 Control Panels
8 Multi-Part Assemblies
