​
Here's an overview of the thin gauge thermoforming process:
Process Steps:
1. Material Selection:
- Thin gauge thermoforming typically involves using thermoplastic sheets with a thickness ranging from 0.2 to 2.0mm.
- Common materials include polystyrene, polyethylene, polypropylene, PET, PETG and special antistatic or dissipative materials.
2. Sheet Heating:
- The selected thermoplastic sheet is heated until it becomes pliable. The heating can be done using various methods, such as infrared heaters or hot air convection.
3. Clamping:
- The heated sheet is clamped into a frame or mold using a vacuum or mechanical method to ensure it maintains the desired shape during the forming process.
4. Forming:
- The heated and clamped sheet is then forced into or onto a mold by vacuum pressure or through mechanical means. The mold imparts the desired shape to the material.
5. Cooling:
- After forming, the material needs to be cooled quickly to solidify and maintain the formed shape. Cooling can be achieved using air or water.
​
6. Trimming:
- Excess material (flash) is trimmed away to achieve the final product. This can be done manually or using automated trimming equipment.
7. Finishing:
- Additional finishing processes, such as surface texturing, printing, or coating, may be applied depending on the desired final product.
