Features
1. The PU low-pressure foaming machine is a self-developed piece of equipment from Lingxin. The raw materials are evenly mixed to ensure the raw material proportions are precise.
2. The equipment is equipped with 15-45 work positions, thus meeting requirements for simultaneous production using multiple molds.
3. The machine head uses a servo motor to drive the belt and automatically control walking. ★The machine head runs smoothly during operation, and the running speed is adjustable from 3m/min to 8m/min.
4. The equipment features automatic and manual opening and closing of the mold.
5. The mold uses an entire situation insulation system, using water as the insulation medium. The temperature is adjustable from 40℃ to 70℃.
6. The rack bottom is equipped with an automatic height adjustment function, which adjusts equipment height for convenient manual operation.
