The Classification Of Plastic Mold

Plastic mold is that used for the molding tool, this tool is composed of various parts. Plastic mold press molding method different, basically can be divided for injection mold, plastic compression mold, extrusion mold, blow mold, plastic mold and high foaming polystyrene molding.

1. Plastic injection mold

Plastic injection mold is mainly thermoplastic plastic products used in the production of one of the most common mold. Plastic injection mold corresponding processing equipment for plastic injection moulding machine. Plastic injection machine first in bottom heating barrel is melted by heating, and then in the injection machine screw or plunger drive below, the injection machine nozzle and mold's gating system into the mold cavity, plastic cooling hardening shaping, demoulding to obtain the products.

2. Plastic compression mold

Plastic mold includes compression molding and injection molding mold type structure of two kinds of. They are mainly used for molding thermosetting plastic in a mold, the corresponding equipment is pressure molding machine. Compression molding method according to the characteristics of plastic, the mold is heated to molding temperature, and then measuring the pressure plastic powder into the mold cavity and a feed chamber, closed mold, plastic in high temperature, high pressure is softened by viscous flow, after a certain period of time is solidified and shaped into a desired article shape.

3. Plastic extrusion mold

Plastic extrusion mold is used to produce continuous shape plastic products forming a mold, also called extrusion die, widely used in pipe, bar, sheet, film, filament, wire and cable coating layer, profile processing. The corresponding production equipment of plastic extrusion machines, the principle is in the heating and solid plastic extruder screw rotation under pressurized conditions melt, plasticizing, through the particular shape of the die and die shapes made of cross section and the same continuous plastic products.

4. Plastic blow mold

Plastic blow mold is used for molding plastic container type hollow products mould. Blow molded form according to the process principle mainly in extrusion blow molding, injection molding form. According to the process principle mainly in extrusion blow molding machine, injection blow molding, injection stretch blow molding, multilayer hollow blow molding, sheet blow molding. Hollow plastic products blow molding the corresponding equipment are often referred to as the plastic blow molding machine. Blow molding is only suitable for the hot varieties of plastic products production.

5. Plastic mold

Plastic mold plastic plates, sheets to molding materials some relatively simple plastic products mould. Plastic mold is to use the principle of vacuum bloom method or compressing air molding method which is fixed on concave or convex die plastic plates, sheets, in a heated and softened case of deformation and affixed to the mold cavity by the desired molded product.

6. High-foamed polystyrene mold

High foaming polystyrene mold is the application of expandable polystyrene raw materials to forming various needed shapes of foam packing material in a mold. Its principle is expandable polystyrene in the mold can into the steam forming, including simple manual operation tool and hydraulic pressure machine type foam mould two types.
