1. There are some commodities such as vehicle covering parts. Airport parts. Small toys. The surface of electrical products is composed of a variety of bevels, some of which must be solved by means of computing power.
2. High processing accuracy: a mold is generally made of cavity. Mold base and mold embryo composition, some may also be a patchwork control module. The composition of upper and upper die, the composition of insert and concave die, and the splicing in the middle of the control module all have high machining precision. The specification accuracy of precision mold is usually up to μm class.
3. Precision mold processing process is more: milling is always used in mold processing. Boring, drilling, reaming and tapping a variety of processes.
4. Repeatable completion and production: the application of the mold has a service life. When a mould outlives its useful life, it needs to be replaced, so the manufacture of moulds is usually repeatable.
5. Large quantity and small quantity: the production and manufacturing of molds is not a large quantity of mass production, and in many cases, only one is usually produced.
6. Copying processing: Sometimes there is no sample drawing or data information in mold production and manufacturing, and the copying processing should be carried out according to the entity. This provides high accuracy of imitation and no deformation.
7. Mold raw materials are excellent, the specific raw materials of high strength mold are mainly selected for production and manufacturing of high-quality carbon steel, especially for molds with high service life. Crl2, CrWMn and other Leytenite steel are often selected for production and manufacturing. This stainless steel sheet is calcined from wool embryo. Processing to heat treatment process are strictly managed. Therefore, the formulation of processing technology can not be ignored, heat treatment process deformation is also a difficult problem to be completed seriously in processing.
According to the above characteristics, in the use of equipment should be as far as possible to achieve the processing regulations. Such as the role of CNC machine tools, CNC lathe precision to high, better stiffness, better heat resistance, with imitation function.
