There are often many types of compression molding machines on the market, for example: Polymer / PTFE Bushing Press Automatic Molding Machine, Polymer / PTFE flange press Automatic molding machine, polymer / PTFE poetry automatic molding machine, semi-automatic molding machine and so on.

Shaping is widely used in the following areas:

Electrical: insulator, switch box, housing for electrical equipment, insulation tools, switchboard, etc.

Automobile: lampshade, front and rear bumpers, battery bracket, soundproof motor board, etc.

Railroad: vehicle window frames, toilet components, seats, tabletops, siding and car roof, etc.

Construction: water tank, bath products, door panels, cleaning tank, building template, etc.

Bathroom: bathtub, integrated bathroom equipment, integrated sink, etc.

And other areas of industry and agriculture.

Molding technology is a process of introducing quantitative molding materials (powder, granular or fibrous plastic) into the metal mold and molding products under the action of temperature and pressure. During the molding process, heat and pressure are required to melt (or plasticize) the molding material, fill the mold cavity with flow, and solidify the resin. The principle is that the process of pressurizing, molding and heating depends on the closing of the heated mold.

Molding machine Technology is the oldest molding method in plastics processing technology. Due to its long history, the molding technology is quite mature, currently the processing of thermosetting plastics and some thermoplastics (fluoroplastics, uhmwpe, polyimide, etc.) is still the most widespread and the main position of the molding process. Molded thermosetting plastic, which is introduced into the cavity of the thermosetting plastic under the action of heat, is first changed from solid to melting, melt flow under pressure with the shape of the cavity and the cavity has increased the resin molecular weight with increasing crosslinking reaction, when the degree of hardening increases, the increases Molding material viscosity gradually increases and solidifies, eventually becoming release products. Thermoplastic plastic mold printing, in the previous phase of the situation and thermosetting plastic the same, but since there is no crosslinking reaction, the mold must be cooled in the flow of the full cavity in order to turn its molten plastic into a solid constant strength can be demodulated into products. Since the compression mold for thermoplastic plastic molds has to be alternately heated and cooled, the production cycle is long, so that thermoplastic products generally choose the injection molding process more economically, only in the mold a larger layer of plastic products or molded part difficult to use due to the flow of the thermoplastic plastic injection molding process.

In the molding material filled with the mold cavity flow process, not only the resin flow but also the reinforcing material to be flowed belong to the high pressure molding, so that the compression molding process is higher than other process methods. Therefore, it needs not only the hydraulic press that can control the pressure, but also the high strength, high precision and high temperature resistant metal nozzle.
