Why use a gas mold temperature machine?
announcer:

The mold temperature machine is the mold temperature control machine, which is called differently in different industries. For example, it is called an oil heater in the temperature control of the PVC sheet roller, a temperature control device in the extruder equipment, a temperature control system in the rubber mixer equipment, or a temperature control machine.

 

These devices are basically rapid temperature rise first, and then heat preservation, in addition to cooling, and then heat preservation equipment. Either way, their purpose is to control the temperature, so that the molten plastic enters the mold with a stable viscosity and is evenly formed in the mold.

 

In the injection molding process, temperature is a very important influencing factor. Whether it is the molding temperature or the mold temperature, it plays a vital role for the injection molded parts. For example, too high a mold temperature will make the product prone to problems such as burrs, discoloration, and difficulty in demoulding; too low a mold temperature will make the surface defects of the product increase or not easy to fill up.

 

On the one hand, the uneven mold temperature will greatly affect the dimensional stability of the product, resulting in a high rate of defective products, and then reduce the production efficiency. On the other hand, the service life of the mold will also cause thermal cracking of expensive steel due to the impact of supercooling and overheating, which will accelerate its aging and increase production costs.

 

Therefore, in order to improve quality and reduce costs, the mold temperature machine has become an inevitable condition for the production equipment.
