Mold Classification General classification of mold: can be divided into plastic mold and non-plastic mold: (1) non-plastic mold: casting mold, forging mold, stamping mold, die-casting mold, etc. A.Casting die – faucet, cast iron platform B.Forging die — automobile body C.Stamping die – computer panel D.Die casting die – superalloy, cylinder body (2) According to the […]
New type plastic mold steel Normal 45 steel or 40Cr steel is often used to manufacture plastic molds.Plastic molds with high hardness requirements are made of steel such as CrWMn or Crl2MoV.For the plastic mould with higher working temperature, the hot die steel with high toughness can be selected.A series of new die steels are […]
Steel requirements for plastic mould Plastic mould working conditions and cold punching die is different, generally must work under the 150 ℃ to 200 ℃, except under certain pressure, and temperature effects.The same mold can have a variety of forms of failure, even on the same mold may appear multiple damage.From the failure form of […]
Failure reason of plastic mould material General mold manufacturing, including mold design, selection of materials, heat treatment, mechanical processing, commissioning and installation and other processes.According to the investigation, the main factors affecting the service life are the materials and heat treatment used in the dies.From the perspective of total quality management, the factors affecting the […]
Plastic mould material requirements Plastic mould working conditions and cold punching die is different, generally must be under 150 ° C to 200 ° C, except under certain pressure, and temperature effects.According to the different use conditions and processing methods of plastic mold, the basic performance requirements of steel for plastic mold are summarized as […]
Plastic mould structure parts 1, composition The structure of blow mold, cast mold and thermoforming mold is relatively simple. The structure of pressure mold, injection mold and transfer mold is complex, and there are many parts that constitute this kind of mold. Basic parts: (1) molding parts, including die, punch, all kinds of forming core, […]
Plastic mould design elements Mould design and manufacture are closely related to plastic processing.The success or failure of plastic processing depends largely on the mould design effect and the mould manufacturing quality, and the plastic mould design is based on the correct plastic product design. The structural elements to be considered in the design of […]
Silicone mould tips The choice of mold form and mold line is very important, one is to take the mold is convenient, two is the mold line should be selected in the overall effect of the product does not affect, three is not affected product quality, such as the waterscape series products mold line position […]
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 […]
