Four variables of scientific injection molding plastics

(Summary description)Figure 1: Four variables of plastics

Therefore, when we are judging whether an injection molding process is stable, we need to evaluate whether the four major variables of plastics are evaluated, rather than simply looking at whether the injection molding machine is stable, whether the mold is stable, and whether the material properties are stable.

Plastic temperature:

The temperature here refers to the melting temperature of the viscous flow plastic. How can the melting temperature be measured? It is impossible to read from the injection molding machine alone. How to get it please think about it. Leave a message to get the answer!

Flow rate:

That is, the flow rate of the plastic, this data can be read from the injection molding machine.

Plastic pressure:

This refers to the pressure of the plastic inside the mold, which cannot be read simply from the injection molding machine. The injection molding machine can only tell you the injection pressure, but there is a pressure loss from the barrel to the nozzle, to the runner and then to the cavity, so it needs to be calculated through experiments.

Cooling rate:

Consistency of the cooling rate can be indirectly guided by measuring the demolding temperature.

Huizheng Information: There are many factors that affect injection molding. If we want to manage and control all the elements together, it will be a very important project, and a lot of sensors need to be installed. Through correlation analysis, we can find that there are actually four variables related to the plastic molding process, namely the temperature of the plastic, the flow rate of the plastic, the cooling rate of the plastic and the pressure of the plastic. Through repeated tests, it has been shown that the quality of products with the same four plastic variables is also highly consistent.
