The screw refers to a cylinder with a spiral groove cut on the outer surface or a cone cut with a spiral groove on the conical surface. It is mostly used in plastic molding equipment, such as plastic profile extruders, injection molding machines, etc. Screw and barrel are the core components of plastic molding equipment. Therefore, quenching the screw to increase its hardness has become a very important part of the heat treatment process. After comprehensive consideration of various factors, our customer chose medium frequency induction heating equipment for quenching and heat treatment of the screw.
When the medium frequency induction heating equipment is used for quenching and heat treatment of the screw, the screw moves up and down while rotating, which greatly ensures the uniformity and consistency of the temperature in each quenching area. At the same time, the faster heating speed of the equipment effectively avoids the oxidation and decarburization of the screw surface, ensuring the quality of the quenched screw.
The medium frequency induction heating equipment has high reliability and has a unique circuit design. The power module unit used constitutes the system. Even if a single power module unit is damaged, it will not cause the equipment to work interrupted, so that the reliability of the equipment operation has been substantially improved. It has complete protection devices: there are alarm indications such as overvoltage, overcurrent, overheating, and water shortage, which effectively protect the safe operation of the machine.
