Huizhou Jin Precision Parts Co., Ltd. to explain to mold Note 1, the preparation process concise, detailed expression, processing content as numerical expression; 2, at the key and difficult process, with special emphasis on the process; 3, requires a combination of processing at craft articulate; 4, inserts sold separately processing, attention to precision machining process requirements stated; 5, after a combination of processing plastic mold structure, the need to separate inserts machined parts, when a combination of machining process to install a separate benchmark requirements; 6 Mold processing springs are the most easily damaged plastic mold supply, so to choose a long fatigue life die springs. European and American manufacturing mold spring long fatigue life, the famous brand Raymond die springs. Kim Hing Precision Parts Co., Ltd. is specialized in mold manufacturing, mold processing, electrode machining, thermal and processing of plastic molds wholesale, if necessary, please call contact information on the picture to contact us. Huizhou Jin Precision Parts Co., Ltd. to introduce you to the hollow mold is prepared by extrusion or injection, and is still in the plasticized state tubular or sheet stock material trends in the fixed mold, and immediately pass into the air, forcing billet expansion and affixed to the wall surface of the mold, and after cooling stereotypes stripping, ie, a processing method to obtain the desired hollow article. Suitable for blow molding of plastic for high-pressure polyethylene, low pressure polyethylene, hard PVC, soft PVC, polystyrene, polypropylene, and polycarbonate. Depending on the plastic mold, blow molding parison extrusion molding method is mainly divided into blow molding and injection blow molding two. Advantages of extrusion blow molding is a simple extruders and extrusion blow molded structure, the disadvantage is the parison wall thickness is inconsistent, likely to cause uneven thickness of plastic products. Advantages of injection blow molding parison wall thickness is uniform, no flash, due to the injection parison with bottom, so the bottom of the hollow article no fight and joints, is not only beautiful but also high strength. The disadvantage is that the price of the molding apparatus and the mold used more expensive, so that this molding method is used for the mass production of small hollow article, not in the use of a wide range of hollow extrusion blow molding method.
