OEM plastics hang tag injection molding

What is plastic molding? Plastic can be made into many shapes. Injection molding is one of them. Injection molding is also known as injection molding, referred to as injection molding. It is the main molding method of thermoplastics. Because it has a wide range of applications, such as Injection Molded Parts For Toys、 newly designed environmentally friendly toy boxes, injection molding of electronic products, with a short molding cycle, high production efficiency, good production conditions, easy to mechanization and automation and other advantages, in the whole plastic molding process plays an important role. Injection molding refers to the particle or powder plastic from the injection molding machine hopper into the high temperature cylinder, heating, melting, plasticizing, so it becomes a flow of melting, and then in the injection molding machine plunger or screw under high pressure, it passes through the nozzle, flow into the mold cavity. After a period of pressure holding, cooling and setting, plastic parts of a certain shape and size can be separated from the mold cavity when the mold is opened. As a result, the time required to complete an injection cycle can range from a few seconds to tens of seconds, depending on the size and thickness of the workpiece.
