Plastic custom moulding is the most common manufacturing process for the fabrication of large quantities of plastic parts. As an ideal method to producing high volumes plastic parts in the same shape, practical injection molding can be used to create various of plastic parts, which vary greatly in size, complexity and application. Almost every plastic item around you was manufactured by injection molding. As a reputable company in China, Zhongde supplies high precision plastic injection mold and molding, with affordable price and considerate service. The plastic injection molding making at Zhongde factory is a standard process involving a stainless steel mold. The whole molding and tooling can be divided into six stages: mold clamping, injection molding, pressure holding, cooling, mold opening, and product removal. At a certain temperature, the completely melted plastic material is stirred by a screw, injected into the mold cavity with high pressure, then cooled and solidified into the final plastic molded parts. When it comes to the type of plastic moulding, custom made plastic molds manufactured by Zhongde are for the satisfaction of every customer, with low price and reduced cost. Besides pp, pu and pvc, Zhongde also provides silicone and polyethylene plastic injection moulding businesses as well. More customized plastic molds are for sale and available at present, such as aluminum plastic injection molds. And the especially popular plastic injection molding: thermoplastic injection molding, short run injection molding, hot/cold injection molding, low volume injection molding...
