Specialist of SSR and Thyristor

Recommandation for Plastic Processing Industry

Kudom provides various types of solid state relay with rated voltage up to 660VAC and rated current up to 125A, which are approved by cUL/TUV/CCC. They are widely used for the precise heating control of plastic machinery.

Extruding Machinery

The extruding machinery is to extrude the molten plastic through the fixed shape of the extrusion port and cut it after cooling. SSR is used for the heating control in the extruding machinery.

Injection Molding Machine

Injection molding machine is the most widely used processing machine in plastic processing industry. The SSR is widely used in this industry for heating and motor control.

Mold Blowing Machine

The mold blowing machine plasticizes the preformed products by heating, and then enters the mold for blow molding. This method is mainly used in the production of PET bottles and BOPP bottles with high-speed and high-yield, that is, the two-step process. Kudom's voltage regulating module and SSR help in the precise temperature control.


SRA solid state relay available with short circuit protection and alarm output function.

When the short-circuit occurs, SRA can shut down the output timely to avoid the damage of product and output alarm signal; Once SRA detects fault is eliminated, it will resume to work automatically.
