With the demand of automobile industry for the production of complex and tortuous conveying pipes, the development of push force off-axis extrusion blow molding technology is called three-dimensional blow molding or 3D blow molding (or multi-dimensional extrusion blow molding MES in some countries). Due to the use of three-dimensional blow molding in the process of […]

For a speeding car, installed in the rear spoiler plays a very important role. In addition to the beautiful decorative effect for the car, more important is spoiler can also effectively reduce the high speed passenger cars under the buoyancy and safeguard the stability of the car, while helping to save fuel. Plastics because of its

For almost all of the extrusion molding, injection molding, blow molding and vacuum molding methods, productivity is largely determined by the efficiency of the heating and cooling of plastic. In blow molding process, the heat of melting plastic is taken away by the mold, the product is cooled and set, and the cooling time of the

Manufacturing time Injection molding process tray has been developed in China for more than 20 years, has been developed in foreign countries for forty or fifty years, relatively speaking, the production process tends to mature and stable; Injection tray in the domestic development for four or five years, has just started, so in the production technology,

One is engaged in blow molding machine plastic molding work of technical personnel and workers, must understand the plastic material. Only to understand the various types of plastic blow molding machine plastic materials，can be applied freely, Selection of raw materials before molding, Or molding process setting, feeding of molding machine, are related to the type of plastic. There are a lot

Plastic barrel hollow blow can be divided into two categories: Extrusion blow molding and injection blow molding. The main difference between the two lies in the preparation of the blank, and then the blow molding process is the same. On the basis of these two methods to carry out: Extrusion stretch blow molding (abbreviated as extrusion blow), injection stretch
