Extrusion mould process instroduction The degree of extrusion deformation is expressed by the area reduction rate before and after deformation.The ultimate deformation degree of the blank without crack in the first deformation process is called allowable deformation degree.The allowable deformation degree is higher when the blank is extruded under three-way compressive stress.In cold positive extrusion, […]
Extrusion mould A pressure machining method in which the blank placed in the die is pressurized by a punch or punch to produce a plastic flow, thereby obtaining a workpiece corresponding to the mold hole or the shape of a concave punch.During extrusion, the blank is subjected to three – way compressive stress. Smart Mold […]
Why is the entrance rounded corner designed for the extrusion mould The role of the fillet radius at the entrance of the extrusion mould hole: Prevent surface crack when low plastic alloy is extruded To reduce the non-contact deformation of the metal when it enters the working zone Reduce high temperature extrusion die inlet Angle […]
Extrusion mould classification According to the mold structure of extrusion mould can be divided into four classification,Integral mould, disassembly mould, combination mould and special mould. Here are theiy main uses: Integral mould,the mold is made from a piece of steel.Widely used for extruding aluminum alloy type, bar and tube. Disassembly mould,by several pieces assembled into […]
Extrusion mould design requirements,the following conditions should be met 1,Die working part should be high enough strength and long service life 2,The die working part can be simply and reliably fixed on the die frame 3,Easily damaged parts can be disassembled easily 4,The blank is easy to place, accurate positioning, can be used in mass […]
