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 […]
punching mold material classification A. Carbon tool steel Carbon tool steel T8A and T10A are widely used in moulds, which have the advantages of good machining performance and low price.But the hardenability and red hardness difference, heat treatment deformation, bearing capacity is low. B. Low alloy tool steel Low alloy tool steels are based on […]
Punching mould material The materials for the punching mould are steel, hard alloy, steel-bonded hard alloy, zinc-based alloy, low-melting alloy, aluminum bronze, polymer material, and the like. Most of the materials used in the manufacture of stamping dies are mainly steel. The types of commonly used mold working parts are: carbon tool steel, low alloy […]
Punching mould terminology basics 1, curling The crimping is a stamping process in which the edge of the process member is wound into a nearly closed circle. The axis of the curled circle is linear. 2, curling edge The crimping edge is a stamping process in which the upper edge of the hollow member is […]
According to the processing methods, the punching mould can be classified as follows a. Punching and cutting die: It is done by shearing. Commonly used forms include shearing die, blanking die, punching die, trimming die, whole edge die, hole punching die and punching die. b. Bending mold: It is a shape that bends the flat […]
Punching mould classification 2 According to the degree of process combination, the punching mould can be classified as follows A. Single process die in a stroke of the press, only one stamping process die is completed. B. Compound die has only one working position. In one stroke of the press, two or more stamping process […]
Punching mould classification 1 Following up the process properties, the punching mould can be classified as follows A. The blanking die creates a mold that separates the material along closed or open profiles.Such as blanking die, punching die, cutting die, cutting die, cutting die, cutting die. B. Bending die a die for obtaining a workpiece […]
Punching mould Punching mould is in cold stamping processing, the material (metal or non-metal) processed into parts (or semi-finished products) of a special process equipment, known as cold stamping die (commonly known as cold stamping die).Stamping, is at room temperature, the use of molds installed on the pressure machine to apply pressure on the material, […]
The role of die casting mould in the production process as follows (1) Determine the shape and size of the casting precision; (2) The determined gate system (especially gate position) determines the filling status of the molten metal; (3) The determined drainage system affects the filling conditions of the molten metal; (4) The strength of […]
Solution for crack of die casting The reason: 1.Shrinkage stress 2.Force a crack in the ejection or entire rim Improvement methods: 1.More rounded corners 2.Check for hot spots 3.Pressurization time change (cold chamber machine) 4.Increase or decrease closing time 5.Increase the drawing Angle 6.Increase the jacking pin 7.Check the mold for any dislocation or deformation […]
