Why do injection molds need to have a trial ?

 Sunday, 29 August 2021

It is impossible to see whether plastic molds are good for injection molding.

Generally, molds will not be directly regarded as final products when they are designed, because they will have one or another defects after they are produced. However, such defects cannot be avoided before manufacturing, and it is likely that they will not be stored and processed during the manufacturing process, Therefore, it is necessary to test the mold, and then analyze, evaluate and optimize the samples produced by the test mold, so as to meet the requirements of high quality.

However, most defects of molded products are caused in the plasticization and injection molding stage, and may also be caused by improper manufacturing of plastic molds. Therefore, in order to avoid product defects caused by mold design, it is necessary to analyze mold design and process parameters when making molds.
