The garment is a huge project which includes design, production. In the process of production, there are also various detailed parts. The most important part is the choice of material. As for the material, there are cloth and other accessories. The other accessories are always called garment accessories which are the necessary factors for the garment. The garment accessories involve hang tags, plastic seals, woven labels, printed labels, metal labels, and fabric labels etc. Woven labels are usual utilized in casual garment, which are sometimes folded in the neckband. Generally, there are some English letters or logo woven on that. The plastic seals often use injection molding. This method is let the molten plastic rapid inject to the mold by injection machine, and make it solidified to obtain a variety of plastic products. Almost all thermoplastics (except fluorine plastic) can be used this method, also be used for some thermosetting plastics molding too. Injection molding accounted about 30% of the plastic production. It can be primary molding a complex shape with precise size, and high productivity advantages. But the cost of equipment and mold is higher, so this method is mainly used for product a large quantities of plastic parts. To produce plastic seals, a injection machine is the item required. This machine has itself own working system. Injection system: the injection system is one of the most important part of the injection molding machine, generally a plunger, screw, screw pre-plastic plunger Note vertical injection molding machine. Shot three main forms. Currently, the most widely used screw type. Its role is in a loop of the plastic injection machines, can be within a predetermined time, a certain number of plastic heating plasticizing, under a certain pressure and speed, by the screw of the molten plastic is injected into the mold cavity. |
