High precision die parts important processing process

High precision die parts in the work in addition to the provisions of a very high hardness and ductility, its surface properties of high precision die parts in the work of performance and life is particularly important.

This kind of performance improvement, simple rely on the improvement and promotion of the base material information is very insufficient, also is not economic development, and according to the surface solution technology, usually can get the actual effect of less effort, which is just the surface solution technology for rapid development and growth. Die polishing technology is the key component of die shell surface engineering project and the main processing technology in the whole process of die processing.

Special attention is paid to that the polishing of the shell surface is not only affected by the harm of polishing machinery and processing technology, but also by the harm of the mirror glass degree of the steel of the mold, which has not caused sufficient high attention, in other words, polishing itself by the steel of the mold. Although new solutions to improve the surface performance of precision die parts emerge in an endless flow, nitriding, nitriding and hard-base film accumulation are mainly used in the production and manufacture of high precision die parts.

Because the surface of the nitriding technology to produce high quality performance, and nitriding process with high precision mold fittings steel heat treatment process has excellent flexibility, at the same time nitriding temperature is low, does not need to fierce cooling after nitriding, the high precision mould parts deformation is small, thus high precision mold parts surface strengthening is to choose earlier nitriding technology, is also the most common use.

Mirror glass mould steel is not just component problem, more specific smelter need to use the vacuum system vacuum distillation, argon gas protection casting, vertical continuous casting machine, rolling mill, the gentle forging and a series of advanced technology, make the mirror glass mould steel with internal faults of small, high residual level of fine particles and diffuse, fine grain size of metal material, good symmetry and a series of advantages, In order to achieve polishing to mirror glass mold steel requirements. The surface solution technology of die parts is an engineering project that changes the shape, composition, organizational structure and pressure of the surface of high precision die parts according to the surface coating, surface modification material or composite solution technology, so as to obtain the required surface performance.

Nitriding processing technology has vapor nitriding, positive ion nitriding, liquid nitriding and other methods, each nitriding method, are several kinds of nitriding technology, can be integrated into different steel brand different product workpiece provisions. The form of surface solution can be divided into organic chemical method, physical method, physical method and mechanical equipment method.
