The Basic Characteristics Of Injection Molding Mould
May 18, 2017

(1) The machining accuracy requires that the secondary mould is generally composed of concave die, convex mould and mould rack, some may be multi piece modular. So the combination of the upper and lower dies, the combination of inlay and cavity, the flattening between the modules requires high machining accuracy. (2) surface complex some products such as automotive panels, aircraft parts, toys, household appliances, the shape of the surface is composed of a variety of surfaces, so the mold cavity surface is very complex. Some surfaces must be handled in mathematical calculations. (3) Bulk small mold production is not large batches of production, in many cases often only production one pay. (4) The process of multi-injection molding process is always used in milling, boring, drilling, reaming and tapping and other processes. (5) The use of repeated production molds is a lifetime. When the use of one-pay mould exceeds its lifetime, the new mould will be replaced, so the production of mould is often repetitive. (6) Imitation machining mould production sometimes has no drawings, no data, and according to the kind of imitation processing. This requires the imitation of high precision, not deformed. (7) Excellent mould material, the main material of high hardness mould is made of high-quality alloy steel, especially the plastic mould which is highly life-span, often used in Crl2,CrWMn such as Laigang. This kind of steel from rough forging, processing to heat treatment are strict requirements. Therefore, the preparation of processing technology is more to be ignored, heat treatment deformation is also the processing of serious problems.
