Dispensing glue is the usual diving port, side glue is the large nozzle, such as the bell mouth, etc. Unlike dispensing, generally no further processing is required. Large nozzles need to be manually separated from the product. There are three-plate mold and two-plate mold for dispensing. The large nozzle is generally a two-plate simple mold.
Injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex shapes. Specifically, the heat-melted material is injected into the mold cavity under high pressure, and after cooling and solidification, a molded product is obtained.
