Application

Plastic/rubber industry

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.

Electric heating furnace industry

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

Semiconductor industry

The temperature control of the electric heating cloth package is often used for the heating of the exhaust pipe valve parts of the semiconductor factory, the panel factory, or the special steel cylinder.

In the semiconductor temperature process control program, the heating system of the chamber, such as the decane process, the dichloromethane process

Ceramic / kiln / glass industry

Ceramic sintering furnace:

The heating process on the sintering furnace controls the heating rate to obtain a finished product with better quality and stability.

Electric kiln:

Temperature adjustment during kiln firing to obtain a finished product with better quality and stability.

Fiber machinery

Dyeing machine:

control the temperature during dyeing to a suitable range, which in turn reduces chromatic aberration and improves the quality of dyed products.

Fiber dryer:

The temperature during drying is controlled within a suitable range to improve the fiber product.
