What is the cause of shrinkage and deformation during the molding process of the hot and cold integrated mold temperature machine? Hot and cold integrated mold temperature machine is widely used in electronics, electrical appliances, die casting, daily necessities, automotive interior parts, rubber and plastic processing of equipment materials, metal die casting, machine tool constant temperature and many other industries
.

The common medium carrier has two conduction modes: water type and oil type.
The microcomputer temperature control circuit controls the heating body to effectively control the heating and constant temperature of the medium.
The temperature is fed into the mold runner, and the mold temperature is rapidly increased to improve the molding efficiency and shorten the molding time of the product.
Using the principle of heat exchange, the heater and cooler in the machine can accurately adjust the temperature of water or heat medium oil, and quickly It circulates in the mold quickly, and maintains a stable temperature during the molding time of the product, so as to improve the product quantity and molding efficiency, so as to obtain the purpose of precise temperature control to assist the normal production of other processing equipment
.

Hot and cold integrated mold temperature machine plastic has no physical properties of thermal expansion and cold contraction.
During the molding process, the product will see a little shrinkage, bubbles, silver streaks, deformation, cracks, uneven performance, defects and other undesirable phenomena, which constitute those undesirable phenomena.
The main reason is that the mold temperature is unstable before the product is unmolded and the mold temperature cannot reach the effective molding temperature of the product during the molding process
.

Engineering plastics such as PC, PA, PBT, etc.
have relatively high temperature requirements.
The heat of the injection molding machine itself cannot meet the optimal temperature necessary for the molding process, and the mold temperature control function quickly increases the mold temperature and can automatically according to the required temperature.
Adjustment, the stability of mold temperature can greatly reduce the defective rate of products Labels:
