What are the basic characteristics of mould processing

Dalian mould machining precision demand is high, a pair of mold is generally composed of concave die, punch and die set, some may be more than a split module. So the combination of upper and lower die, panel board and the combination of cavity, split between modules are require high machining accuracy. The size precision of precision mould tend to grade microns. Fractal surface is complex, some products such as automotive covering parts, aircraft parts, toys, household appliances, the shape of the surface is made up by a variety of surface, therefore, the mold cavity surface is complex. Some surface must use mathematical calculation method for processing. Small batch, the mould is not large batch production, in many cases tend to produce a pay. Process, mould processing is always used in milling, boring, drilling, reaming and tapping screw and so on a variety of processes. Repeatability and put into operation, the use of mould is a life. When the use of a pair of mold exceeded it's life-span, will replace the new mold, so the mold production is often repeated. Sometimes neither in contour machining, mold production pattern, also does not have the data, and according to the physical objects using the copying process. This requires a generic high precision, no deformation. Excellent mold material, high hardness, the main material of the mold is made of high quality alloy steel manufacturing, more especially high life of the mold, often use Crl2, CrWMn ledeburite steel manufacturing, etc. This kind of steel from the blank forging, heat treatment processing to have strict requirements. So the processing technology of more nots allow to ignore, deformation and heat treatment processing in the problem that need to be taken seriously. Many characteristics, according to the selected machine to meet the processing requirements as much as possible. Such as the function of CNC system, machine tool precision, better rigidity, better thermal stability, with functions of copying, etc.
