What should be paid attention to in the processing of injection molds? What is its key?

  In terms of molds, the micro injection molding of mold processing equipment is significantly higher than traditional injection molding. There are generally two trends in injection mold processing: one is to use mirror EDM machine tools to ensure high precision in precision mold processing, and EDM should use graphite electrodes because the loss of graphite electrodes is much smaller than that of ordinary copper electrodes. Compared to general processing methods, another approach is to use electrical modification and select electroplating techniques to ensure high accuracy. However, the disadvantage is that the processing cycle is long, each point needs to be injection molded, and there are slight damages during production that cannot be corrected and can only be replaced with damaged molds.

In the mold, mold temperature is also a very important parameter for injection mold processing. In the face of unique requirements, the current comparative approach is to borrow the concept of high gloss injection molding and introduce a rapid heating and cooling system. In theory, introducing injection molds at high temperatures to prevent thin-walled filling is very useful. However, excessively high mold temperatures can bring new problems such as reducing deformation and shortening, so introducing a new mold temperature control system is appropriate.

 During the processing of injection molds, the mold temperature can be advanced (exceeding the melting point of the plastic used) to allow the melt to quickly complete the cavity and prevent a temperature drop during the filling process. Too fast, incomplete filling; When disassembling the mold, the mold temperature will decrease and remain slightly below the plastic's thermal deformation temperature before opening the top. In addition, because micro injection molding is the quality of Millennium Data products. Less than 10% of the data needs to be injected into injection molded products, and there are many gating systems, so injection molds can choose to use gating systems.
