What is Vacuum Forming?

Vacuum forming is a widely used plastic processing technology. Its principle is as follows: A thermoplastic sheet is first heated to a softened state, then placed over a mold and the edges sealed. A vacuum pump is then activated to remove the air between the sheet and the mold, using atmospheric pressure to force the softened sheet to adhere tightly to the mold surface. After cooling and setting, a product conforming to the mold shape is obtained.

The core advantages of this process are low mold cost and short production cycle. It is particularly suitable for producing large-size or small-batch thin-walled products and is widely used in packaging, advertising, automotive interiors, and appliance casings.

Vacuum Forming Process

Vacuum forming, also known as thermoforming, is a widely used secondary molding technology for thermoplastics. Its core principle is to use vacuum suction to tightly adhere heated and softened plastic sheets to the surface of a mold, forming a product of a specific shape after cooling. This process is known for its low mold cost, high production efficiency, and suitability for producing large-size products. Of course, vacuum forming is an economical, efficient, and flexible plastic processing technology. When choosing this process, its advantages of low cost and large size must be weighed against its limitations of uneven wall thickness and limited detail. For large, thin-walled products with simple structures, small batch sizes, and cost sensitivity, it is an irreplaceable ideal choice.

01
Sheet Clamping
Secure the cut plastic sheet to the clamping frame, ensuring it does not shift or loosen during heating and forming.
02
Heating
Use a powerful heater (such as a ceramic infrared heater) to uniformly heat the sheet to a specific high-elasticity state, softening it and making it malleable. At this point, the sheet will become soft and droop.
03
Mold Transfer and Sealing
Move the softened sheet above the mold (male or female mold) and seal the edges of the sheet with the mold platform.
04
Vacuum Forming (Core Step)
Start the vacuum pump, and quickly remove the air between the sheet and the mold through tiny vacuum holes in the mold. Due to the pressure difference of atmospheric pressure, the sheet material is pressed tightly and rapidly onto the mold surface, perfectly replicating the mold's contour.
05
Cooling and Shaping
The formed product is forcibly cooled by air cooling or cooling water channels within the mold, causing it to re-solidify from a highly elastic state to a rigid state.
06
Demolding and Part Removal
The vacuum is released, the clamping frame is opened, and the product is removed from the mold using ejector pins or manually.
07
Subsequent Processing
The formed product is removed from the frame and excess material is trimmed using methods such as stamping or CNC milling to obtain the final product.
