Now, China has become a major manufacturer of moulds. According to incomplete statistics, the sales volume of the whole industry (including domestic sales and export) has reached nearly 250 billion yuan. In the view of the industry, this number is not important, the important is our country's mold industry system has been basically perfect.
First of all, the leading enterprises in each mold industry are already present. Have four people, such as automotive covering parts mould enterprise large plastic mould enterprise first haier moulds, precision stamping die enterprise includes the sheng, huafu, etc, they all have played an important role in leading the industry progress.
At the same time, the mold product structure is more reasonable. According to the material and forming method of the product, the mold is divided into 10 categories, mainly including stamping die, injection mold, die-casting mould, forging die, glass mould, etc. At present, the mold structure ratio is about 40% of the stamping die and plastic mold. Luo baihui, executive vice President and secretary general of the international model association, said that the mold product structure type can reflect the comprehensive level of the mold industry in a country. In the past, we used to make up 70 percent of the industry. Now our product structure is basically the same as that of developed countries.
In addition, in recent years, the development of mold industry has become a new feature of industry development, forming the production base of kunshan and wuxi precision mold industry cluster. Botou, wuhu automobile mould industry cluster production base; Ningbo, huangyan, shenzhen, dongguan large precision mold industry cluster production base. According to the international model association executive vice President and secretary general luo baihui investigation, now the country has completed or the scale of the mold park about 50 or so. Especially for mould manufacturing services system is increasingly perfect, from the mold material, processing equipment, processing tools, dedicated to mold design software development form of the latter's professional industry, which laid the groundwork for the rapid development of the mould industry in China.
But from the overall, mould industry in our country and the developed countries than there is a certain gap, mainly reflected in terms of mold development and production, is generally used to developed countries such as concurrent engineering and project management technology and management methods, to strengthen the control of the workflow, shorten the development cycle. In specialized production, developed countries are more common. In research and development of new technology innovation, including forming method innovation, forming quality improvement, innovation of new material forming technology, we have not the initiative, is basically to follow behind the technological development in the developed countries.
Mould equipment manufacturing industrial power dream.
The industry of a country wants to revitalize cannot leave the advanced manufacturing technology, and the mold should be in the first place of advanced manufacturing technology undoubtedly. Therefore, the level of mold technology has become an important indicator of the level of a country's manufacturing industry. Our country wants to realize the dream that makes great power, mould must first.
From the cylinder body of the car's heart generator to the stamping parts of the automobile body, the hot pressing mold of the new material and the domestic production of the core parts of the car need to be driven by the mould. It can be said that mould equipment is an important part of automobile equipment.
In addition, in the home appliance industry, the importance of mold industry is also increasingly apparent. For example, the manufacture of a refrigerator needs 150~200 molds, an air conditioner needs about 50 molds, a washing machine needs 60 or so molds, and a large number of small appliances... Only haier's annual purchase of 6,000 or so molds is more than 500 million yuan.
According to the introduction, in haier mold company, there is a place generally not open to the outside, this is the product design research and development center. Haier, he thought, the key to the company's products to market quickly is that haier mould company product design research and development has realized the integration with haier company, it's for haier company's new product velocity provides valuable time.
The above is only in the people's livelihood, in fact in the national strategic security of aviation and aerospace industry mold also plays a crucial role.
Now there are more requirements for light quantification in aviation manufacturing. How to meet this demand, you have to do your homework on sheet metal equipment and airplane interiors.
The airplane has a cart for catering, which has been made up of boards in the past, and is now studying the feasibility of replacing plastic with plastic, which puts forward new requirements for plastic materials and molds. For example, the plastic must be strong, flame retardant, smoke proof, easy to heat and so on. According to incomplete statistics, one aircraft only has the mold of the interior decoration in 200 sets, and the production value of the mold can reach 100 million yuan. Now China mold and die industry association is organizing related businesses for aircraft interior parts of material selection, product structure analysis and design, mold design and manufacturing and assembly of a complete set of the final product technology research and development, realize the industrialization of complete set technology of aircraft interior parts.
Due to its high precision, good consistency and beautiful appearance, the moulds have been used more and more in the construction of aircraft, ships and high-speed trains. In addition, the production process can achieve high efficiency, high volume and energy saving, so the mold is often praised as the mother of modern industrial production.
