The current situation of abrasives industry and countermeasures
abrasive grinding machine tool industry is an important branch of industry, and its products are widely used in processing and manufacturing industries, and in recent years
involving applications continue to be expanded. Abrasives in large metallurgy, machinery, electronics, small to small dental grinding, female grinding wheel ,
Who used to trim the nail metallographic paper industries and fields in the applications. In recent years, has also been widely used in high-grade refractory
abrasives, engineering ceramics and high wear-resistant materials, automobile exhaust purifier and so on. In the international financial crisis situation, under the
influence of known processing system
Manufacturing industry, "teeth" said abrasive products also sparked waves of toothache. Tooth almost? Dental care almost? Undoubtedly, our abrasives industry is facing
a major change.
Technological innovation, increase investment
A competitive advantage business, its core competence is reflected in the constantly-leading proprietary technology and long-term accumulation of well-known brands.
According to market demand, bold technological innovation, constantly introducing new products, improving production technology, improve product technology and
Quality grade, technological transformation of existing industries in order to achieve product structure adjustment and industrial upgrading program. Our country is a
major exporter of abrasives products country, but exports especially abrasive products for the resources of primary products. The State of introduction of China's
manufacturing
Outside the production technology supporting abrasive products, but dominated by the imports.
Understand the situation, and actively respond to
Our country is the largest producer of abrasives, but mainly concentrated in the lower end of the market, compared with the international advanced level there is a
large gap, mainly in: 1, high-tech products can not meet the market demand, dependence on imports. Middle and low structural surplus generic products, making
A backlog of payment arrears and price wars; 2, industry-wide production capacity has reached a certain size, but the actual production capacity of more scattered,
small scale, poor economies of scale; 3, technological development capacity is weak, its own intellectual property products and technology less, there is no charge
Grip product development initiative; 4, less product variety, low-tech, manufacturing process data demonstrate the lack of rigorous testing can not maintain continuous
product quality and stability; 5, abrasives industry, domestic brand gold content is low, there are fewer international brands .
Currently, abrasives industry is facing decline in international demand and domestic policy adjustment challenges, the industry should assess the situation, a positive
response, speed up structural adjustment and transition.
Currently, the world economic downturn and financial crisis and other factors, the EU and the U.S. decline in demand for abrasives products. However, demand is not
declining demand was eliminated, but the financial crisis has reduced liquidity arising from the decline in trading volume, with increased mobility
Plus, fairs gradually restored. It should be said, in Europe and other developed countries, from equipment manufacturing to cosmetics, abrasives is widely used. From
years of the situation, superhard materials of synthetic diamond and CBN, with a rapid increase; while ordinary abrasive, using several
Volume is relatively stable, but profits will be gradually reduced. As the financial crisis, the U.S. and Europe are trying abrasives suppliers using a variety of ways
to reduce costs, lower prices, for example, to increase overseas cooperation to reduce costs, this will help abrasives products
Increased imports. While U.S. exports of high value-added products are mainly sol-gel products and superhard materials. A large number of R & D investment in Europe
many manufacturers of sophisticated products, occupying high ground, to obtain higher profits, profit margins and gradually give up a lot of middle and low production
. Europe's common abrasives production will be attempted through a variety of ways to lower-cost local production.
