We will also introduce the mechanism of vacuum forming! If you are having trouble with vacuum forming, leave it to Thermotech.
At Thermotech Co., Ltd., we perform "vacuum forming." We heat plastic sheets with a heater to soften them and then align the softened plastic sheets with the molding die. The softened plastic sheets are closely adhered to the molding die using vacuum power and cooled down. Once cooled, the stable molded products are released from the molding die using compressed air. Finally, the molded products that have been released from the molding die are cut with a die to complete the product. 【Process】 ■1. Heat the plastic sheets with a heater to soften them ■2. Align the softened plastic sheets with the molding die ■3. Adhere the softened plastic sheets to the molding die using vacuum power and cool them ■4. Release the cooled and stable molded products from the molding die using compressed air ■5. Cut the molded products released from the molding die with a die to complete the product *For more details, please refer to the PDF document or feel free to contact us.
