According to the statistics of Prospective Industry Research Institute “2014-2016 China Plastic Mould Industry Development Prospect Forecast and Transformation Upgrade Analysis Report”, the top ten plastic mold enterprises in China in 2015 are listed below (in no particular order): Jiangyin Moulding Group Co., Ltd. Company Hongzhun Precision Mould (Kunshan) Co., Ltd. Herbi (Tianjin) Electronics Co., Ltd. Shengmei Precision Industry (Kunshan) Co., Ltd. Jinsheng Precision Components Co., Ltd. Yinbaoshan New Technology Co., Ltd. Hong Kong Yihe Precision Industry Holdings Co., Ltd. Beieruo (Guangzhou) Engineering Plastics Co., Ltd. Changhong Mould Technology Co., Ltd. Ningbo Shuanglin Mould Co., Ltd. Hengxingchang Mould Technology Co., Ltd. has five of the top ten in the Pearl River Delta region, two of which are located in the city. Another four are concentrated in the Yangtze River Delta region, two of which are in Kunshan. The report also stated that China's plastic mold industry achieved sales revenue of 83.545 billion yuan in 2012, an increase of 13.21%. Quote: In 2009-2012, driven by the sustained and rapid growth of the industrial economy, Guangdong's mold industry developed rapidly.

According to statistics released by Huangpu Customs on August 5, Guangdong Province exported US$360 million in molds in the first half of 2009, compared with last year. In the same period, the growth rate was 12%, and the total export volume exceeded the second-ranked Zhejiang Province by more than double, making it the “China's largest mold province” and the molding technology is close to the international level. In the past two years, China's mold manufacturing technology has continued to improve. China has been able to produce multi-station progressive die with an accuracy of 2 microns and a service life of more than 300 million cycles. The multi-station progressive die produced by individual companies can be used on high-speed punches of 2000 times per minute with an accuracy of 1 micron. Coastal areas, especially Guangdong Province, are at the forefront of the industry in terms of the overall quantity and quality of mold manufacturing. The molding technology is close to the international level of developed countries such as Japan, the United States, Germany and Italy. Under the situation that the world economic variables have increased in 2009 and China's manufacturing industry has responded positively, the “Equipment Manufacturing Industry Adjustment and Revitalization Plan” recently adopted by the State Council of China has made the technical level of upgrading molds and their manufacturing equipment a key content. It is understood that Guangdong Province exported 190 million US dollars of molds to Hong SMC moulds factory Kong in the first half of the year, an increase of 18%, accounting for about 70% of total exports; exports of molds to the EU more than 50 million US dollars, accounting for 20% of the total. This year, GM declared bankruptcy, and foreign auto companies shuffled. These companies will develop new models, and the molds they use will go to developing countries such as China. Luo Baihui, an expert in China's mold industry, believes that despite the current economic downturn in the international mold market, Guangdong mold companies still have a lot of room for development. With the rapid development of domestic energy-saving technology and automobile industry, the application of new material technology in the mold industry has ushered in new opportunities; the rapid growth of the consumer electronics market and the rise of the medical device industry have also provided the development of mold, molding and surface decoration technology. The huge platform puts higher demands on the mold forming technology. At present, molds, high-performance, polymer materials and their molding are high-tech industries supported by the state, but high-precision mold manufacturing equipment and molding equipment, as well as large, complex, long-life, high-precision molds rely on imports. High performance, high strength, polymer materials and their molding technology are also mainly dependent on foreign countries.

According to the plan, the Ru0026D center consists of 7 research laboratories, including the new product design room, the new material technology research room, and the product and technical standard preparation research room. After the establishment, it will be responsible for the introduction, absorption, digestion, innovation and improvement of new products, new materials, new technologies, new processes and equipment, and project research and development according to the development of the enterprise and market demand. To undertake research on national, provincial and municipal scientific research projects, promote corporate intellectual property protection, and train technical and management talents for enterprises, and provide technical training for enterprises and industries. The Ru0026D center will provide scientific and technological services or scientific and technological achievements to the small and medium-sized enterprises in the domestic industry for transfer, promote the development of industry and industry, and plan to complete more than 10 projects including nano metal coating materials and anti-oxidation and explosion-proof magnesium alloy materials from this year to 2012. To verify and accept the work, we will strive to become a national engineering center within three years. In 4 to 5 years, the research and application in the field of mold design and manufacturing technology, new materials and its molding process and equipment technology, non-conductive vacuum coating process and equipment technology has reached the international leading level. As a supporting unit, City Hengxingchang Mould Technology Co., Ltd. has carried out independent research on 15 projects in mold, molding, coating and industrial automation equipment. Enterprises and major technology management research institutes establish a relationship of industry-university-research cooperation alliance, which can jointly undertake national, provincial and municipal scientific research tasks.

The thimble adopts the hasco or dme standard, which is determined by the mold technical requirements determined by the bom table or other formal notices. The effective locking length of the screw must be SMC moulds factory sufficient, normally 1. If there are two or more inclined guide columns in the same row position, the length, size and inclination of the inclined guide columns must be the same. Drill holes must not be drilled, and sharp angles must be chamfered. A proof of material must be provided, and if it is a hard mold, a heat treatment report must be provided. 7. For the beading and wear-resistant plates, wear-resistant hard materials must be used, and oil grooves are required. The row guide column must be pressed tightly and cannot be rotated or loosened.

The inclined top seat is generally hardened with 2510 or cr12 to hrc40-45 degrees. The diameter of the positioning ring must conform to the drawings.15mm. The form and position of the top joint must conform to the drawings. Except where otherwise specified. The inner mold and mold parts must not be welded without consent. 20, the front and back inner molds of all molds, inserts, row position, slant top, straight top (push block), shovel chicken, etc. Because the inclined top seat is subjected to the impact load, it cannot be too hard or it will break and chamfer the c angle at all right angles. . 18. 11. 10, the conventional structure mold must be arranged with the head, the two ends need to be smoothed, the small mold pre-pressure 0. 5.
