As China's market development pallets, plastic pallets production process technology and the specific production process to become the industry spotlight. We used pallet generally divided into two: Injection blow molding trays and trays, the following two trays to make a brief introduction: 1, blow molding tray: high molecular weight high density polyethylene blow molding mold once production. 2, injection molding tray: low-pressure high-density polyethylene by injection molding. Here molding tray production technology and processes some introduction: 1, mold: Injection molding machine can be divided into the clamping device and the injection device. Clamping device for opening and closing the mold to perform stripping operations have shown toggle mode, and the use of hydraulic cylinder direct the opening and closing of the mold direct pressure mode. The injection device is then melted by heating the resin to be injected into the mold at this time, to rotate the screw and allow the resin into the hopper stay in front of the screw, through the amount of resin equal to the stroke required for the storage and then emitted. When the resin flows in the mold, the control and the moving speed of the screw after the resin is filled with a pressure (holding pressure) control. When the screw reaches a certain location or a certain pressure from the injection velocity control is switched to pressure control. 2, injection mold: Mold is: In order to make some kind of shape resin material, and for receiving a metal injection into the resin type. The dissolved material from the gate into the mold via the flow channel and then filled into the mold cavity of runner. Then you through the cooling engineering and open molding machine mold stripper plate ejection lever, push the top of the molded product. 3, injection molding: molded by resin melt flow gate, into the cavity of the flow channel with the product part of the composition. As a forming operation can be made of a product, so efficiency is not high. If we can take advantage of a number of flow paths link the cavity, several products can be formed simultaneously. At this time, when the respective cavity is not the same flow channel length, can not also filled with a resin, and most of the cavity size, appearance, physical properties are different, so usually the same as the length of a flow channel design.
