Face of financial crisis, the State Council's "equipment manufacturing restructuring and revitalization plan" to enhance the mold and the technological level of manufacturing equipment as its key content in the country based on 16 major science and technology project equipment features special projects related to the mold , plastic film also reflects the mold industry in the manufacturing share of importance. Luo Baihui senior industry experts believe that the central range of the stimulus plan to boost domestic demand, difficulties encountered in the mold to market opportunities.
How to seize the 4 trillion yuan total investment opportunities of construction projects into the mold industry, color film real order? Luo Baihui that, unprecedented opportunities, the development of mold industry in China is to solve the basic problem of mold materials and mold-related technological backwardness of the status quo.
pvc shower curtain New opportunities bring new challenges
International Association for steel mold Li Guang-chao, the Commission's experts, mold materials, performance, quality and variety of mold often the quality of life and cost of domestic and imported steel, tool steel compared to both the quality and variety of specifications, there is a wide gap. The car dies, for example,pvc plastic film Chinese automotive industry and the rapid development of tooling industry the quantity of mold material, quality, variety and performance and other aspects of the higher and newer requirements, such as the user requires high standards of die steel materials have a very good impact toughness, residual elements of control, high-quality, long life. pvc color film The die steel because domestic varieties, specifications, quality and performance and other reasons, and the international advanced level there is a gap, resulting in 25% of the annual high-end mold must be imported from abroad.
Wang Jinling,pvc film table cloth Deputy Secretary-General of the International Association for that model, a car from microelectronic components to the body, tires, etc., including plastic, glass, copper, aluminum, steel and other strength and surface condition of different parts, and that any car to zero Part of the production process, if required the physical properties of each component, the appearance quality Dengjun fully meet the design requirements, the quality of the mold must be guaranteed. Die die first requires the user not the overall total failure, which requires the mold not the overall cracking. Second, the mold user requirements to produce the first and the last one auto parts have the same physical properties, appearance, and dimensional tolerances, so the mold material must ensure sufficient strength.
Wang Jinling, said that with the development of lightweight vehicle, die-casting production tends to use more pressure, more automated die casting machine to produce, so the mold worsened working conditions, which requires the mold material also has excellent red hard (high-temperature yield strength) and ductility (plasticity).
State Key Laboratory of Mold Center vice president of weeks Dongguan victory that is indeed disturbed die steel mold manufacturer to be a problem, especially for those medium-sized mold manufacturers. Such as a large block of the mold steel, mold steel optional domestic and reliability are low, can not meet the time requirements are very tight project, so the cost of mold manufacturers had to use high import tool steel.
Urgent domestic steel mold
The face of newly emerging huge market, domestic steel companies are full of emotion and embarrassment: At present, domestic steel die die can not all meet the domestic needs of the industry. China Mould Industry Association Committee noted that the mold material, the domestic steel market has lagged behind the die mold industry, the mold can not be well adapted to the needs of the manufacturing sector, mainly in the following areas:
The first is the production process behind the die steel, steel quality is poor. Such as die steel-made generic h13, d2, ld, and other varieties can achieve internal quality standards of the United States die steel universal astma681, an international general level, the mold can basically meet the domestic and general users. However, the high standard die steel users by the same high requirements, such as impact toughness, carbon and other residual elements control low bias, high-quality long-life requirements, is still not satisfied. Requirements, such as cold working die steel at low temperatures with resistance to abrasion, anti-sex-shaped plastic, anti-chipping, cracking anti-whole can be grinding and machining of various properties. The plastic mold steel requires a high-quality finish, corrosion resistance, wear resistance, high thermal conductivity, mechanical processing, polishing, etching properties.
Deputy Secretary-General of the International Association for Wang Jinling, said mold, hardened steel tool life abroad in the 160 to 300 million times, there were only 50 to 100 million, non-hardened steel die life abroad and only half the country. Quality of steel is caused by one of the reasons for this situation. In addition, fewer new varieties of domestic mold steel. In recent years, some famous foreign enterprises die steel die steel developed many new products, such as high strength and toughness die steel, dh13, dh53, flame hardening die steel, powder metallurgy cold work tool steel, high performance tool steel into the current the international market, the typical mold brand products. In contrast, domestic fewer new high-performance tool steel, die steel less development of new varieties.
There is a variety of specifications are not complete. For example, die steel consumption accounted for 60% of the plastic mold steel, alloy tool steel standards in China, only two of steel, while the United States has seven steel, and steel to form a more complete series. United States, Japan, France and Switzerland, has been in cold die steel and hot work tool steel formed in series, only the hot die steel have six common varieties of shape, is the reach of domestic mold steel.
