In terms of molds, the micro injection molding of mold processing equipment is much higher than traditional injection molding. There are generally two trends in injection mold processing: one is to use mirror surface electric discharge machine tools to ensure high precision in precision mold processing, and graphite electrodes should be used for electric discharge machining, as the loss of graphite electrodes is much smaller than that of ordinary copper electrodes. Compared to general processing methods, another method is to use electrical transformation and choose electroforming techniques to ensure high accuracy. However, the disadvantage is that the processing cycle is long, and each point needs to be injection molded. There are slight damages in production that cannot be corrected, and only damaged molds can be replaced.
In molds, mold temperature is also a very important parameter for injection molding processing. Faced with 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, excessive mold temperature 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 (which can exceed the melting point of the plastic used), allowing the melt to quickly complete the cavity and preventing temperature drops during the filling process. Too fast, incomplete filling; When disassembling the mold, the temperature of the mold will decrease, keeping it slightly below the thermal deformation temperature of the plastic, and then 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 be chosen to use gating systems.
