The Course Of Development Of China Die & Mold Industry Analysis
By the financial crisis, China’s southeast coastal enterprises, especially export-oriented enterprises affected by large manufacturing enterprises around the mold is hardly the financial crisis is relatively small, the country developed to the casting mold industry today, gone through a difficult process, until 1976, still backwardness. Since 1977, due to China’s machinery, electronics, light industry, instrumentation, transportation and other industrial sector to flourish, the number of casting molds need more and more increasingly high quality requirements, delivery time has become shorter. Therefore, the rise of China’s relevant departments attach great importance to the casting mold industry, will die as a “65” “75” plan key scientific research projects, send people abroad to study tours, the introduction of foreign advanced technology, casting mold, casting mold to develop the country standard. Through this series of measures, making casting mold industry has made significant progress, and certain technical aspects of a breakthrough. The second car plant to adopt new technologies, new materials for the Japanese Isuzu large-scale factories for producing high-quality casting molds, has won a good international reputation.
1980, Shanghai has been able to create a mold cavity 400 large-scale thermosetting plastic packaging mold, die casting demands shape and position of this error is small, the surface roughness of less than 0.1um. Subsequently, appliances large and complex plastic molding casting molds have gradually succeeded in the trial; the average life of 4 million red grinding times, these Carbide burr 0.5um progressive die has also been captured, this 6-position rotor film production Casting Mold is close to international advanced level. At the same time, it produced more than 10-bit precision progressive die work, and have a high degree of difficulty precision casting mold plastic molding, and through digesting imported technology, research-micron-level precision multi-position progressive die multi-cavity mold plastic molding. In addition, the casting mold computer-aided design (CAD) computer aided manufacturing (CAM) technology is also beginning a study, and achieved initial results. During this period, casting mold industry really has been greater development. National Casting Mold factory has reached more than 6,000 points, the number of employees by about 30 million people, producing about 80 million sets of die casting, the standard mold base more than 160,000 sets of die casting industry in China has begun to take shape.
In recent years, been the introduction of advanced manufacturing technology, advanced equipment, spare parts mapping, there is generally no longer uses the rubbing method, a model law, while the use of CMM laser scanner and other advanced measuring equipment, measurement techniques, mapping parts that are not accurate, rapid, and the measured data can be entered into the computer graphics, the establishment of various documents to show the three-dimensional model of two-dimensional graphics parts. Design, because CAD universal application, many companies factories has got the drawing board or are being cast off the drawing board, such as three-dimensional modeling software, and promotion efforts, not only to provide a guarantee for the integration of CNC programming, you can also design for assembly interference checking to ensure that Design Technology rationality. Processing, CNC machine tool widely used not only to ensure the quality of casting mold parts processing precision and high cutting speed, high feed, high-speed processing quality as the main features of processing technology, more efficient than conventional machining times even 10 times. Some on the scale, the level of casting mold factory continue to emerge, some non-technical, non-standard, poorly equipped workshops gradually been eliminated in hand, so that casting mold industry in China, there has been rapid development.
Under such circumstances, we should highlight the issue of precision casting mold out to promote the casting mold industry in China entered a new stage of development, give full play an important role in the national economy casting mold industry. With the times, so that the rapid growth of China’s national economy, accelerate the realization of the four modernizations, becoming an economic power, scientific and technological power.
