With the market demand for plastic products become more and more, also began to have more and more manufacturers began to produce injection molded parts. We all know that our lives are used in many products are plastic products, such as toiletries, toys and so on. Speaking of plastic products, we have to talk about plastic processing technology - injection molding processing, do not know how much understanding of Changzhou injection molding, the following small series on the simple to tell you about how the injection molding process is the lower limit of temperature The bar.

1, filling process to take a one-dimensional heat, the corresponding cooling is one-dimensional cooling.
2, after the high temperature fluid into the product after molding the specific heat capacity, with their own thermal conductivity are unchanged.
3, in the process of forming products, abrasive and plastic parts are in a constant temperature field.
4, in this constant temperature field, when the central temperature is equal to the temperature when the plastic deformation of the temperature, the end of the entire cooling cycle. This also shows that the limit point has two roles. In short, according to different injection requirements, the upper and lower limits of the temperature is different, so in many cases are the need for specific problems specific analysis.
