What exactly does an injection molding engineer do?

1. The work scope of injection molding engineers is not only medical materials, but also various plastic products, such as medical supplies, industrial parts, daily necessities and so on. Main responsibilities: responsible for the identification of medical plastic particles; Quality control of disposable medical diagnostic products; According to the performance of polymer materials, product design, sample making and testing are carried out. Main tasks: Responsible for the injection process control of various plastic products (there are many kinds of plastic raw materials for injection, different manufacturers have different material properties, and the injection process parameters are inconsistent. Because there are many materials, the process parameters should be determined before injection, including injection temperature, injection time and injection pressure. ); Solve the process and quality problems in the injection process, prepare for some possible technical quality problems in advance, and prevent the occurrence of batch quality accidents. In the process of pressing parts, because the die is cold at the initial pressing, the dimensions of initial pressing and later pressing have changed; Due to the high temperature during pressing and poor manufacturability of some parts, deformation problems are easy to occur; Due to the precision of mold manufacturing, some parts will have some burr problems, which are easy to deform due to large shrinkage; Parts with good fluidity have large burrs after pressing, and parts with poor fluidity (with glass fiber and flame retardant) will have unsatisfactory pressing problems (parts are short of materials).
