Due to the important role of molds in the manufacturing industry, the mold manufacturing industry has been receiving attention and attention from the developed countries of the world. In fact, the design and manufacture of molds has become an important area of ​​manufacturing. Luo Baihui, the head of the International Association of Moulds and Plastics Suppliers and the deputy secretary-general of the Shenzhen Mould Technology Association, believes that modern mold enterprises have demonstrated the characteristics of technology-intensive, capital-intensive and high-quality labor intensive and high social benefits. The mold manufacturing industry has become a high-tech. As part of the manufacturing industry, the level of mold technology is becoming an important indicator of a country's manufacturing level and a core competitiveness to maintain the advantages of these countries' products in the international market.
China's mold manufacturing level has increased significantly
After nearly 30 years of rapid development, China's mold industry has become a world mold power. According to Wu Bingshu, secretary-general of China Die & Mould Industry Association, China has become a big country in manufacturing and a big mold producing country. In 2010, sales will be close to 100 billion yuan (95 billion yuan in 2008), and mold imports are nearly 2 billion US dollars. , maintaining a four-year import level of 2 billion US dollars; mold exports close to 1.9 billion US dollars, is basically the same as in 2008, but mainly rely on imports in the middle and high-end molds. The Chinese government attaches great importance to the development of the mold industry and mold technology, especially since the reform and opening up, fully affirmed the important basic position of the mold industry and technology in the manufacturing industry and the national economy. The state has invested a large amount of money to improve the manufacturing level of key molds. This major project has projects such as C-class car body cover moulds.
According to Luo Baihui, deputy secretary-general of Shenzhen Die & Mould Technology Association, in recent years, China's mold manufacturing level has been greatly improved, and the proportion of high-level molds represented by large, precise, complex and long-life molds has reached more than 35%, such as automobile coverage. The mold has been able to produce the B-class vehicle complete vehicle mold; the precision mold processing precision can reach 0.5μm; the precision progressive mold can be used on the high-speed punching machine of 2000~2500 times/min; the plastic mold precision reaches the micron level, adapt The demand for the development of the IT industry; a single set of tires with a weight of 120T and a diameter of 4m become the largest mold.
Purchasing direction of technology upgrade in China's mold industry
Luo Baihui, head of the International Association of Moulds and Plastics Suppliers, said that mold manufacturing is now moving towards the extremes of both big and small. The demand for precision and heavy equipment has also increased accordingly. The mold company has a considerable amount of equipment purchases in a year, and the equipment needed for mold manufacturing, especially high-end equipment, is mainly imported. In recent years, with the improvement of the level of domestically produced equipment, many mold companies have chosen domestic machine tools.
Statistics show that in 2009, China's machine tool consumption reached 19.8 billion US dollars, more than one-third of the world's machine tool market share, accounting for 35.7% of the world's machine tool output, and imported machine tools close to 6 billion US dollars. Among them, high-speed, high-efficiency, precision, composite, flexible, green, and all-manufactured measurement unit manufacturing as the main equipment is still the procurement direction of China's mold industry technology upgrade, heavy load in mold processing, large program quantity, square worktable structure design and The detection and control technology, the high programming resolution of the CNC system, and the high-speed servo control software and hardware environment are the key to ensure the manufacture of precision molds. Ultra-precision mirror milling machines, nano-scale turning and milling composite centers, and ultra-precision CNC lathes have also been used in mold making.
When referring to the current situation of China's mold processing equipment market, Luo Baihui introduced that Japan, Europe and the United States high-end mold processing and manufacturing equipment, measuring equipment has a monopoly position, the reason is of course inseparable from the quality of their products, but also with them The strategy of the Chinese mold market is related. Their demand for the mold market is an active service. They cooperate with mold users to develop mold-specific functions for machine tools and tailor-made functions. Korean machine tools and machine tools in Taiwan have a good price/performance ratio in mid-range models, so they also occupy a certain market share. In terms of mold processing, since some of the materials used in the mold are super-hard materials, the mold manufacturing requires a high degree of tooling, and the tool is required to cut materials of more than HRC60. Luo Baihui said that for high-precision, high-efficiency, high-reliability modern tools, such as hard alloys and ceramics, the consumption of indexable tools is about 1.2 billion yuan, of which 80% to 85% are imported, mold More than 90% of the tools used in manufacturing are used. High-precision cutting tools for five-sided machining and complex motion are still the main procurement targets for the mold industry with overseas products.

Color: Kempas heartwood is very light in color, usually white to light yellow. Kempas sapwood is more orange to red or reddish brown. Over time and with exposure to UV light, the floor will darken to a more reddish color.
Grain: The grain is interlocked and/or spiraled, and is generally rough.
Variations within Species and Grades: There is little variation within the species and grades.
Hardness/Janka: Kempas has a Janka Scale rating of 1,710, making it harder than most species used for hardwood flooring.
Dimensional Stability: This particular species of wood is not considered dimensionally stable, and is less stable than the traditional Northern Red Oak.
Sawing/Machining: Sawing and machining kempas is somewhat difficult because of hard deposits. It can dull and damage tools so it is important to be careful when working with kempas.
Sanding: Kempas is known to sand well.
Nailing: It may be difficult to nail because of how easily the wood may split.
Finishing: The coarse texture and acidic nature of the wood make finishing more difficult than some other species. It will need good filling to finish and polish well.
Availability: Limited availability.
