Introduction to tungsten steel round rod

Tungsten steel round rod introduces the standard parts of die with larger output in China and the rapid development of die manufacturing technology

At present, the standard parts of molds with large output in China are mainly mold frames, guide parts, punches, pushing rods and tubes, elastic components, etc., oil-bearing guides and inclined wedges for automobile molds, etc. These products are not only in large demand for domestic supporting, but also have a good export prospect. Die for automobile covering parts. In order to meet the sustainable development of the automobile industry, the automobile covering parts die manufactured for a large number of new models will develop rapidly, requiring the automobile covering parts die enterprises to have shorter processing cycle and higher processing accuracy.

Tungsten steel round rod large and medium-sized precision plastic mold. Large precision plastic molds mainly serve for automobile and household appliances industries, such as bumper, instrument panel, fuel tank, steering wheel molds for automobile, and large and medium-sized plastic molds for color TV, washing machine, refrigerator, air conditioning and other household appliances. From the current capacity, domestic manufacturing molds account for about 60% of the market share.

Small and medium-sized precision mold. There are many kinds of this kind of mold, and the service range is very wide. The high-speed development of information industry, manufacturing industry and mechanical and electrical industry are their biggest markets.

At present, the domestic has a large output of mold standard parts are mainly die frame, guide parts, punch, push rod and tube, elastic components, automotive mold with oil guide plate, wedge, etc. These products are not only a large number of domestic supporting needs, export prospects are also very good, in the next few years will continue to develop vigorously, foreign large mold standard parts enterprises have begun to flood China.

Mold manufacturing technology is developing rapidly

The rapid development of mold manufacturing technology has become an important part of modern manufacturing technology. The rapid development of mold manufacturing technology has become an important part of modern manufacturing technology.

The laser rapid molding technology of the mold, the precision forming technology of the mold, the ultra-precision machining technology of the mold, the dynamic simulation technology of the flow, cooling and heat transfer process using finite element method and boundary element method in the mold design, the CIMS technology of the mold, the DNM technology of the mold that has been developed and the numerical control technology of the mold, almost covers all the modern manufacturing technology.

First, high speed milling: the third generation of die making technology

High speed milling of tungsten steel round rod not only has high processing speed and good processing accuracy and surface quality, but also has low temperature rise (only 3℃ increase of workpiece) and small thermal deformation compared with traditional cutting, so it is suitable for the processing of temperature and thermal deformation sensitive materials (such as magnesium alloy). Also because of the small cutting force, can be applied to thin wall and poor rigidity parts processing; A series of advantages such as hard material (HRC60) processing can be realized by reasonable selection of cutting tools and cutting parameters.

Edm milling and "green" product technology

From the point of view of foreign electric machining machine tools, no matter in terms of performance, process index, intelligence, automation degree has reached a very high level, at present the new trend abroad is to carry on the research and development of EDM milling technology (EDM generating technology).

Three, the new generation of mold CAD/CAM software technology

At present, the mould software developed in Britain, America, Germany and other countries and some universities and research institutes in our country has the characteristics of intelligentization, integration and manufacturability evaluation of the new-generation mould CAD/CAM software.
