Zinc is one of the most versatile die cast metals. It provides higher precision with lower tooling costs when compared to other die cast metals like aluminum or magnesium. Zinc Die Casting also offers a broad range of excellent physical and mechanical properties, finishing characteristics, and is the easiest to cast. Die casting is a versatile, efficient and economical process for producing engineered metal parts.

At the end of 2010, Zhejiang Province issued the “Zhejiang New Material Industry Development Plan (2010-2015)â€, which clearly stated that Zhejiang Province will focus on the development of new electronic information materials, new energy materials, new metal materials, new inorganic non-metallic materials, and new chemical materials. , New textile materials and 19 categories of products in six areas, including chemical industry focus on fluorine chemicals, organic silicon, engineering plastics and synthetic materials.
In the area of ​​fluorinated materials, Zhejiang focused its development on high value-added fluororesin, ethylene-tetrafluoroethylene copolymer, transparent fluorocarbon resin for fiber, perfluorinated ion exchange membrane, perfluoroether rubber, liquid fluoroelastomer, and solar film. Materials, fluorine-containing liquid crystal materials, etc. In the field of silicone materials, high-performance silicone rubber, special silicone resins, and organosilicon and organic fluorine modified materials have been developed. In the field of engineering plastics, we will focus on the development of polycarbonate, fluorosilicone elastomer materials, polyurethanes, polyurea elastomers, etc., and vigorously develop resin composite materials using aramid, ultrahigh molecular weight polyethylene, polyphenylene sulfide, and other specialty fibers as skeletons. . In the area of ​​macromolecule polymeric materials, the focus will be on development of bimodal polyethylene special resins, transparent polypropylene special resins, high impact polystyrene resins, high performance ABS resins, thermosetting resins and other special polyolefin resins to speed up butyl rubber and ethylene propylene. Rubber, nitrile rubber, rare earth and high-styrene-based butadiene rubber, and other national production facilities for rubber products that are in short supply, are actively developing and introducing high-performance rubbers such as fluorosilicone rubber, acrylic rubber, and isoprene rubber.
Since the beginning of this year, favorable policies have been frequently introduced throughout Zhejiang Province to support the development of the three major synthetic materials industries: rubber, plastics, and fibers. They have given priority to project approval, tax incentives, and financial support, creating favorable conditions for the rise and development of the industry. . The reporter learned from the interview that the number of the three major synthetic materials projects launched in Zhejiang this year has reached as many as several dozen, more than any previous year, and many of these major projects are at the leading position in terms of investment scale, technical level, and product level. Level. For example, on May 28th, Chuanhua Group settled its composite material industry base project in Jiaxing Port Area, focusing on the development of synthetic rubber varieties mainly consisting of carbon 4 and carbon 5. The total investment of the base is about 8 billion yuan. The first phase of the 5 projects will invest 3.2 billion yuan, of which the total investment of the 100,000 tons/year butadiene rubber project will be about 700 million yuan. In July, Zhejiang Xinhui Synthetic New Material Co., Ltd., located in Jiaxing, completed the construction of a 70,000-ton/year halobutyl rubber project on the basis of the successful production of a 50,000-ton/year butyl rubber. In addition, the company is also active. Declaration of ethylene propylene rubber project. The 50,000 t/y nitrile rubber production plant of Ningbo Shunze Rubber Company located in Ningbo Petrochemical Economic and Technological Development Zone is currently the largest single-unit nitrile rubber plant in the world. It has now entered the trial production stage. The project has introduced nitrile rubber production technology developed by the Russian Lebedev Synthetic Rubber Research Institute and obtained funding support from the Ministry of Science and Technology and Ningbo International Science and Technology Cooperation.
In addition, there is also an isoprene rubber project of Ningbo Jinde Haiqi Co., Ltd., which is currently under construction. The polyphenylene sulfide fiber and composites project of Zhejiang Xinhecheng Co., Ltd. located in Shangyu Industrial Park, Shaoxing, is now under construction. Construction; The 200,000-ton/year caprolactam project jointly invested by Sinopec and Zhejiang Hengyi Petrochemical Company is currently at the end of its construction and is expected to be commissioned in April next year. After the project is completed, it will become the largest single-line capacity project in the world. The polyacrylamide-based carbon fiber independently researched and developed by Ningbo Institute of Materials Chemistry, Chinese Academy of Sciences, has now completed the pilot test. After inspection by an authoritative organization, the product quality has reached the level of Japan's T700. The Institute is actively preparing to expand production. A batch of chemical projects such as the 30,000-ton/year silica-based carbon-based degradable plastics project of Taizhou Bangfeng Plastics Co., Ltd. and the 50-million-square-meter EVA solar adhesive production line of Hangzhou Forster Chemical Company are under construction.
Up to now, there are three major industrial blocks in Zhejiang, including the composite material industry, that have begun to take shape and are relatively mature: First, China Chemical New Material (Jiaxing) Park, and secondly, Quzhou Fluorine, a leader of Juhua Group. Silicon new material industry cluster, and the third is Jiande Fine Chemical Industry Cluster led by Zhejiang Xin'an Chemical Group. Relying on the existing industrial base and the industrial development plan, the Zhejiang Provincial Government has made the following arrangements for the future industrial layout: Ningbo, Jiaxing, Taizhou, and Wenzhou have focused on the development of composite materials and engineering plastics, and Hangzhou has focused on establishing an organic silicon new material industrial base. , Shengzhou actively builds a new high-tech industrial base for fluorosilicone new materials.
On December 14, the Zhejiang Development and Reform Commission convened relevant industry experts to review the projects included in the 2011 strategic emerging industry financial special fund project summary table. Among the 42 strategic emerging industrial projects that have been reviewed, chemical projects including synthetic materials accounted for 13 and nearly one-third of these projects. These projects will receive major support from provincial-level financial special funds. Chen Wensen, director of Zhejiang Provincial Technical Expert Committee, believes that in the next five years, Zhejiang's composite materials industry will usher in a new round of investment and development boom.
Die casting offers a broader range of shapes and components than any other manufacturing technique. The die casting process requires a steel mold. These reusable steel molds, called dies, can be designed to produce complex shapes with a high degree of accuracy and repeatability. The dies are mounted into a machine that injects molten metal into the dies under high pressure. Once the molten metal has solidified, the die is opened and the casting is ejected from the mold. The die is then closed and the process starts over.
Zhejiang: Policy promotes the high-end scale of synthetic materials
In the first year of the “Twelfth Five-Year Planâ€, the composite materials industry began to set off a new investment boom. Among them, Zhejiang Province, which has a solid fluorosilicone industry base, has become a bright spot.
