Extrusion die belongs to one kind of molding die, except that his way of discharging material is to realize the elephant through the action of extrusion. It is widely used in aluminum profile structure, and also used in plastic parts. In the front end of extruder, it is used to make pipes, or profiles. In short, a mold is a tool used to form an object, and this tool has a variety of parts, and different molds are composed of different parts. It is mainly through the physical state of the molded material changes to achieve the shape of the object processing.

Extrusion mold can be described by a metaphor: the bottom of the pump gouge on a ruler-shaped hole, the air outlet blocked, pumping the piston, the cylinder filled with yellow mud, inserted into the piston suspension "pumping", you can get an extrusion of the "triangle". This pump is the extrusion mold. In fact, extrusion molds and this is almost the same, high strength, with powder metallurgy tungsten carbide as the "base plate", with a hydraulic press "pumping".

Industrial production for injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping, stretching and other methods to get the required products of a variety of molds and tools.

Extrusion mold application range

Extrusion mold simple classification

According to the different materials molded, the mold can be divided into metal molds and non-metallic molds. Metal molds are divided into: casting molds (non-ferrous metal die casting, steel casting), and forging molds; non-metallic molds are also divided into: plastic molds and inorganic non-metallic molds. According to the different materials of the mold itself, the mold can be divided into: sand mold, metal mold, vacuum mold, paraffin mold and so on. Among them, with the rapid development of polymer plastics, plastic molds and people's lives are closely related. Plastic molds can be generally divided into: injection molding molds, extrusion molds, gas-assisted molding molds and so on.
