At present, the plastic mold in the mold industry accounted for about 30% share in the mold import and export as high as 50 to 70%. In recent years, China's rapid development of plastic mold. The application of plastic products is increasingly widespread, providing a very broad market for plastic molds.
In addition, under the impetus of high-tech drive and pillar industry application demand, China's plastic mold has formed a huge industrial chain. From the upstream raw material and auxiliary materials industries and processing and testing equipment to downstream machinery, automobiles, motorcycles, home appliances, Electronic communications, building materials and other major applications industries, the development of plastic mold vitality.
At the same time, the demand for plastic in construction, household appliances and automobiles is very high. It is estimated that only the automobile and motorcycle industry needs more than 100 billion yuan of plastic molds each year, and the color TV plastic molds also have an annual market of about 2.8 billion yuan.
We can see that the general trend of the mold market is steady upward trend in the mold market in the future, the development of plastic molds will be higher than the other molds in the mold industry will gradually increase the proportion.
Plastic mold processing technology trends.
(1) Increasingly large mold parts and high productivity parts require a multi-cavity mold, resulting in increasingly large-scale molds, large tonnage of large mold up to 100 tons, a mode of hundreds of cavities, thousands of chambers, requiring mold processing Large equipment table, increase the y-axis z-axis travel, large load-bearing, high rigidity, high consistency.
(2) mold steel mold processing high hardness, mold processing equipment requires thermal stability, high reliability.
(3) complex cavity and multi-functional composite mold, with the complexity of the shape of the workpiece, you must improve the mold design and manufacturing level, a variety of grooves, a variety of materials in a set of mold forming or assembly into a component Multi-functional composite mold, it requires a large amount of programming process, with a deep comprehensive cutting ability and high stability cavity, improve the processing difficulty.
(4) The refinement of mold processing make the processing equipment more complex and efficient more attractive. High-speed milling can be processed with high-hardness materials, smooth processing, cutting force is small, the workpiece temperature deformation and many other advantages so that mold companies pay more attention to high-speed machining.
(5) high dynamic accuracy. The static performance introduced by the machine tool manufacturers can not reflect the actual processing conditions when the three-dimensional mold surface is processed. Three-dimensional surface of the mold precision machining, but also put forward the requirements of high dynamic precision performance, high speed and high precision but also in the high rigidity of the machine tool, thermal stability, high reliability and high quality control system can be achieved.
