Method for manufacturing of deep-drawn products from heated thermoplastic semi-finished part, involves performing complete heating of thermoplastic semi-finished part by microwave heating

摘要

The method involves performing a complete heating of a thermoplastic semi-finished part (1) by a microwave heating (6). The thermoplastic semi-finished part is preheated (4) before the complete heating. The temperature of the thermoplastic semi-finished part is partially lowered by a controlled use of a cold air nozzle after the complete heating. An independent claim is included for a thermoforming machine for manufacturing of deep-drawn products from heated thermoplastic semi-finished part.
