Of the last century 30's, the U.S. has developed the first mold technical standards, the implementation of use, the mold formed industrial production scale. After 40 years of effort, to the late 70s, mold standard parts for medium and small-mode use of coverage has reached more than 90%; large-scale die in more than 40% of the parts have also been standardized. This will significantly enhance the level of mold design and manufacturing. Mold standard parts of China have long been a small-scale production, varieties of different specifications less poor circulation. In recent years, through the efforts, Die frame, injection mold, putting push tubes, etc. The concentration of production and use Despite the substantial increase in coverage, but the status quo as compared with the market demand is still fairly far behind. Especially the middle and low product more than the less high-end products, a number of foreign-invested enterprises producing high-grade mold standard parts, due to high cost has affected the promotion and application.
Powder injection mold manufacturing, manufacturers number. It is estimated that national production injection mold manufacturers for more than a total of 40, most of them less than 1000 sets of annual production capacity, there are companies with more than 10000 sets of capacity less than 10. One Lung Kee Group, Dongguan Ming-Steel Mold Co., Ltd., Guangdong Shunde Desheng companies as well as a new powerful mold the company's production scale belong to the first phalanx, each enterprise injection mold billion yuan annual output value is up, and some may be up to several hundred million dollars. Heavy steel company in the village of Suzhou, Shenzhen, south mold factory in Shenzhen Hing Industrial Company Longhua, Shenzhen Xing Long Machinery Mold Co., Ltd., a large-scale frame Kunshan Co., Ltd., Zhejiang Asia-round Mold Co., Ltd., Sichuan Jiangdong Machinery Plant, Nantong Dragon Machinery Co., Ltd., Kunshan Hong Son is a large-scale mold Co., Ltd., the second square, plastic injection mold an annual production value is up to 1000 million yuan. This is a total of two squares in more than 10 plastic injection mold companies can reach an annual output value of more than 20 billion yuan, accounting for more than 90% of the national total. According to demand, across the country is about more than 30 billion injection mold. And the vast central and western regions of northern China, due to a lower degree of specialization and historical causes of some of the stereotypes has not yet been fundamentally changed, so mold injection mold production units required for the majority of their own self-made and very few are still outsourcing. Therefore, the current market for plastic injection mold mainly concentrated in the Pearl River Delta, followed by the Yangtze River Delta region. Which is most concentrated in Guangdong, followed by Zhejiang, Jiangsu, Shanghai and Shandong. As users increasingly demanding mold production cycle is short, so medium-sized plastic injection mold manufacturing companies have started to pre-dug hole cavity and playing such as deep processing of direction, and has achieved good results.
Push tube specialized production in many parts of the standard mold Gaode the best coverage of their use has reached almost 100%. Push tube market, production and demand are basically balanced. PUNCH Industry (Dalian) Co., Ltd. is China's production of Push tube's largest enterprise, Guangzhou strength mold standard parts company with an annual output capacity of 30 million, in addition, putting Factory Guangzhou Donghua mold, Guangdong mold Zengcheng rich and powerful Industrial Co., Ltd., Anhui Leader Die Standard, Tianjin Hedong mold standard factory and Tianjin Zhenhua Gong Hua Die Standard Parts Co., Ltd. has about 10 million production capacity. The output of the above-mentioned seven companies account for about 80% of the national total. Manufacturers have taken note of improved technology, increasing product variety, improve product quality and grades, as well as the importance of the further development of specialized production. In particular, among the best of several companies are trying to use the advanced technology of transformation, to improve their ability to compete in the market.
To this end, experts pointed out that there should be accelerated to promote the following aspects: speed up the establishment, perfect mold standard system, so that standard parts products parameterization, in order to meet the standard parts and mold-scale production of digital design and manufacturing requirements; to improve the standard mold pieces of commodities, manufacturing precision and quality to ensure that the use of technology, safety and interchangeability requirements; research, design, new varieties of standard parts and make the series, parameterization, to meet the die structure design requirements; specification standard parts market, regulate the standard items the accuracy, quality and price. |
