Applications

It is installed on the heating material tube of the injection molding machine to control the temperature of the raw material, effectively control the liquid temperature of the plastic and improve the molding quality of the product.

Installed on the hot runner system for temperature control of runners and gates to stabilize the quality of the plastic.
Temperature control on the mold temperature machine, indirectly adjusting the temperature of the mold by adjusting the temperature of the hot fluid, can improve the production efficiency of the product and reduce the generation of defective products.

Vacuum furnace equipment / vacuum melting / vacuum heat treatment

A new algorithm for PID adjustment using fuzzy rules is used to adjust the PID algorithm to eliminate the PID saturation integral phenomenon when the error is large. When the error is small, the improved PID algorithm is used for adjustment and can be automatically adjusted. Learn and memorize some of the characteristics of the controlled object to optimize the effect
