The quality of plastic products produced by plastic processing equipment is closely related to mold temperature

Moulds in plastic processing equipment are very important for temperature control. If the mold temperature is too high for the shape and size of plastic products will have a great impact, whether curing, dimensional accuracy or production efficiency will decline. Therefore, the mold of plastic processing equipment should be in a reasonable temperature, so that the performance of all aspects of the plastic products produced will be guaranteed, and the temperature regulation is very necessary.

First, the necessity of temperature regulation

The mold temperature of plastic processing equipment has a great influence on the molding quality and molding efficiency of plastic parts. In the mold with high temperature, the fluidity of the molten glue is good, which is conducive to the filling cavity of the glue and the appearance surface of the rubber parts with high quality, but it will make the curing time of the glue become longer and easy to deform when ejecting; Different adhesives have different processing properties, and the surface requirements and structure of various adhesives are different. In order to produce glue parts that meet the quality requirements in an effective time, it requires the plastic processing equipment mold to maintain some temperature. The more stable the mold temperature is, the more consistent the requirements of the size and shape of the produced glue parts, the appearance and quality of the glue parts are.

Therefore, in addition to the factors of die manufacturing, die temperature is an important factor to control the quality of rubber parts. The control method of mold temperature should be fully considered in mold design.

Second, the principle of mold temperature control

In order to ensure that plastic processing equipment can produce plastic parts with high appearance quality requirements, stable size and small deformation in effective time, the basic principles of mold temperature control should be clearly understood when designing.

1. Different rubber materials require different mold temperatures.
2. The die with different surface quality and structure requires different die temperature，This requires plastic processing equipment in the design of temperature control system with targeted.
3. The temperature of the front mold is higher than the back mold, and the temperature difference is generally about 2~3º.
4. The front mold temperature required by the fire pattern is higher than that required by the general smooth surface. The temperature difference is generally about 40º when hot water or oil is required for the current model.
5. When the mold temperature of the actual processing equipment cannot reach the required mold temperature, the mold should be heated up. Therefore, when designing the mold, the heat brought into the mold by the glue should be fully considered to meet the mold temperature requirements.
