Stamping die: divided into punching die, bending die, drawing die, compression die. Process metal plates.
Plastic mold: divided into pressing molding mold, injection molding mold, extrusion molding mold, blow molding mold, vacuum molding mold. Processing thermosetting plastic, thermoplastic plastic.
Die-casting die: Pressure casting die. Process low melting point alloys.
Forging die: Forging die. Process metal.
Powder metallurgy die: pressure forming die. Process metal powder.
Ceramic mould: pressure forming mould. Process ceramic powder.
Rubber mold: divided into pressing molding mold, injection molding mold, extrusion molding mold. Processed rubber.
Glass mold: divided into pressing mold, blow mold. Processed glass.
Casting mold: sand mold, shell mold, wax loss mold, pressure casting mold, metal mold. Work molten alloy.
2 PLATE MOLD is also called single parting surface MOLD, which is the simplest one in injection MOLD. It divides the whole MOLD into two parts: moving MOLD and fixed MOLD with the parting surface as the boundary. Part of cavity is moving mold; Part of the cavity is fixed. The main channel is in fixed mode; The shunt duct is provided on the parting surface. Open MOLD, the products and the flow channel in the dynamic model, dynamic model part with ejection system (2) three board mould or fine runner mould (3 PLATE MOLD, PIN - POINT GATE MOLD) has two MOLD parting surface is divided into three parts, more than two PLATE MOLD GATE PLATE, suitable for the occasion of the sides of the products are not allowed to have a GATE mark, the mould adopts POINT GATE, so called fine runner mould. The structure of this mold is correspondingly more complex. 3. The HOT RUNNER MANIFOLD has the help of the heating device to ensure that the plastics in the gating system will not solidify and also will not demode with the product, so it is also called MANIFOLD without flow. Advantages :1) no waste 2) can reduce injection pressure, can use multi-cavity mold 3) can shorten the molding cycle 4) improve the quality of products suitable for hot runner mold features :1) plastic melting temperature range is wide, low temperature, good fluidity; At high temperature, it has good thermal stability.2) It is sensitive to pressure and does not flow without pressure, but it can flow when pressure is applied.3) It is less than heat, easy to melt and easy to cool.4) It has good thermal conductivity, so that it can be cooled quickly in the mold. Available hot runner plastic: PE, PE, ABS, POM, PC, HIPS
