With the rapid development of plastic industry, and the promotion and application of plastic products in aviation, aerospace, electronics, machinery, shipbuilding and automotive industries, the scope of application of injection mold is more and more extensive. Injection mold is a tool for producing plastic products; It is also a tool to endow plastic products with complete structure and precise size. Injection molding is a processing method used in the mass production of some parts with complex shapes. Specifically, it refers to the injection of heated melted plastic into the mold cavity under high pressure by an injection molding machine, and the molded products are obtained after cooling and curing.

Dalian hollow forming electric tool box is used to inject molded products into one mold and then transfer them to another mold for air blowing. It is commonly used for small hollow products! The wall thickness of the produced product is uniform, and there is no suture, waste and scrap.

In terms of protection against electric shock, the tool not only relies on basic insulation, but also includes an additional safety precautions. The method is to connect the accessible conductive parts with the protective (grounding) conductor in the installed fixed line, so that the accessible conductive parts will not become electrified in the event of basic insulation damage.

Its rated voltage exceeds 50V. In terms of protection against electric shock, the tool not only relies on basic insulation, but also provides additional safety precautions for double insulation or reinforced insulation and measures without protective grounding or depending on installation conditions. There are two types of tool shells, metal and non-metal, but the hand-held part is non-metal, and the non-metal part is marked with a "back" symbol.
