| Plastic tray injection molding process |
| Injection molding: the process of injecting molten material into a mold to obtain a molded product by cooling and curing. First, injection molding in accordance with the following order: 1, mold 2, injection 3, holding 4, cooling 5, mold 6, take out the product Two 、 injection molding machine injection molding machine can be divided into mold and injection device. The die closing device is a die for opening and closing to perform demoulding operations, and a press cylinder is used to directly open and close the press mode of the die. The injection device is heated to melt and then into the resin mold to the rotating screw, and at this time, as shown in the figure let into the hopper of resin stuck in the front end of the screw rod, the equivalent to the required amount of resin storage after injection stroke. When the resin flows in the mold, it controls the movement speed of the screw and controls it with the pressure (holding pressure) after the resin is filled. When a certain screw position or a certain injection pressure is reached, the speed control is switched from pressure control to pressure control. Three, injection mold refers to the resin material in order to make a certain shape, and to undertake the injection of resin into the metal type although not shown in detail records, but in fact there are several empty holes, and temperature management with warm water, oil heater, etc.. The dissolved material is poured into the mold from the gate and then filled into the mold slot through the runner and runner. Next, through cooling engineering and die opening machine, the mold on the stripper bar is removed from the template to push out the forming material. Four. The molding product of injection molding is made up of the runner which flows into the melting resin, the runner and the product part. As a result of forming operations, only one product can be produced, so the efficiency is not high. A number of products can be formed at the same time by using several grooves in the runner. At this point, when the channel length of each mold slot is not the same, it can not fill the resin at the same time, and most of the mold groove size, appearance and physical properties are different, so the flow path will usually be designed to the same length. Specializing in the production of plastic pallets, plastic pallets, plastic pallets, plastic pallets, plastic pallets in Suzhou, Henan, Hefei, Inner Mongolia, Hebei, Shanghai plastic tray, plastic tray, plastic tray, Beijing Zhejiang affordable. |
