How to define the upper and lower limits of temperature in the processing of injection molded parts

With the growing demand for plastic products in the market, more and more manufacturers began to produce injection molded parts. We all know that many of the products we use in our lives are plastic products, such as toiletries, toys, and so on. Speaking of plastic products, let's talk about the plastic processing technology - injection molding processing. I don't know how much you know about injection molding processing. Now, the injection molding manufacturer will simply introduce how to define the lower limit of temperature in injection molding processing.

1. The mold filling process adopts one-dimensional heat conduction, and the corresponding cooling is also one-dimensional cooling.

2. After the high-temperature fluid enters, the specific heat capacity and the thermal conductivity of the product after molding are unchanged.

3. In the process of product forming, the abrasive tools and plastic parts are in a constant temperature field.

4. In this constant temperature field, when the center temperature is equal to the temperature of plastic during thermal deformation, the whole cooling cycle ends. This also shows that the limit point has two functions. In a word, the upper and lower limits of temperature are different according to different injection requirements, so in many cases, specific analysis is required for specific problems.
