Mold is an important process equipment for the forming process of parts. It is an important basic equipment for manufacturing industries such as automobiles and motorcycles, electrical appliances, IT electronics, OA office equipment, transportation facilities, building materials, sanitary ware and medical equipment. Due to the high precision, consistency, and aesthetic appearance of products molded with molds, they are increasingly used in the manufacture of structures and interior parts for aircraft, ships, and high-speed trains. In addition, the production process can realize high-efficiency, high-volume production, material saving, and energy saving. Therefore, the mold is often hailed as the mother of modern industrial production.
Due to the important role of molds in the manufacturing industry, the design and manufacture of molds has become an important area of ​​the manufacturing industry. The mold manufacturing industry has therefore been receiving the attention and attention of industrial developed countries in the world. Due to the characteristics of the mold itself, most of the modern mold enterprises are characterized by technology-intensive, capital-intensive and high-quality labor-intensive and high social benefits. The mold manufacturing industry has become a part of the high-tech manufacturing industry. The level of mold technology has become an important indicator of the level of manufacturing in a country. It is also the core competitiveness of maintaining the advantages of these countries' products in the international market. According to Luo Baihui, the secretary-general of the International Model Association, China has become a big manufacturing country and a big die-manufacturing country. There are 30,000 mold manufacturing companies in China and more than 1 million employees. In 2010, sales reached 112 billion yuan.
1. China's mold and die industry is basically a tool-intensive and technology-intensive equipment with a high-tech industry characteristics and is characterized by high-tech industry characteristics. Manufacturing industry.
2. The production of moulds has come from the art-based manual production mode, which is mainly led by the traditional, fitter-master, and has entered the era of modern industrial production that generally adopts digital and informationized design and production technologies.
3, China's mold industry has evolved from a single public-owned enterprise form to a new pattern in which private enterprises are the main form and multiple ownership enterprises form coexistence.
4. The development of the manufacturing industry has driven the development of the mold industry. The development of the mold industry has given strong support to the manufacturing industry.
5, mold product structure is more reasonable. The method of forming differs depending on the material of the product. Die is divided into 10 categories, the main stamping die, injection mold, casting die, die casting die, forging die, rubber tire die, glass die and so on. The current structural ratio of China's molds: stamping molds account for about 37%, plastic molds about 43%, casting molds (including pressure casting molds) about 10%, forging molds, tire molds, glass molds, and other molds account for 10 %. It is consistent with the proportion of mold categories in industrial developed countries.
Metal Frame Wiper Blade
Unlike traditional windshield wipers, the boneless windshield wipers do not have the support of the skeleton. Instead, they are assembled with 4 parts including wiper strips, boneless wiper blades, wiper sheaths, and plastic parts. Under this design, not only the wiper is more flexible, compared with the traditional wiper, the force and wear are more uniform, which can achieve a better wiping effect, and it also further improves the driving safety.
