injection molding PA66 parts Manufacturers

the plastic processing industry is quite vigorous, with the continuous progress of material technology, the injection molding process is now more and more mature, many manufacturers have been able to master this technology to produce and process plastics. In the middle of the injection molding process, the demand is often applied to a few molds, and the quality of the mold simply affects the quality of plastic products to some extent, so for the operator, the application of the tube mold is the basic requirement. What events do you need to pay attention to in the middle of the application process of injection molds?

The characteristics of plastic injection molding are determined by the characteristics of the raw material, and there are two main points: one is the filling activity of the plastic melt during injection, and the other is the shrinkage position of the plastic in the mold cavity when it is cooled and cured. These two points determine the difference of the injection mold and the difficulty of the injection mold design. When designing injection molds, it is necessary to inquire about the characteristics of the processed plastic raw materials, so that the designed injection mold is more reasonable, and the characteristics of plastics are usefully exercised in the design process. Therefore, the questions that need to be considered in the injection mold design process are as follows.

The plastic box injection mold is composed of two sides, fixed mold and fixed mold, and the rear mold is placed on the moving template of the injection molding machine, and the fixed mold is placed on the fixed template of the injection molding machine. When injecting and molding, the back mold and the fixed mold are closed to form a pouring system and cavity, and the back mold and the fixed mold are separated when the mold is released, which is convenient for removing the plastic product.

During the continuous operation of the mold, it is easy to cause problems such as wear of parts, deterioration of lubricants, water leakage, and crushing of plastic materials during the movement process, so mold maintenance is required.

The peek material can be injection molded. PEEK is a high-temperature special engineering plastic and needs to be maintained at about 350 degrees. This requires the heating section of the injection molding machine barrel to continuously and stably provide a heating temperature above 350 degrees. The melting temperature of the peek material at high temperature is relatively high, and the viscosity in the molten state is relatively large, and the pressure required for injection molding is higher, and the wear of the screw is greater. In addition, peek injection molding requires heating, which is different from ordinary injection molding. It is recommended to find a manufacturer that specializes in peek injection molding to avoid certain technical risks.
