Traditional hardware tools face the pressure of change and find the way to survive

The number of hardware tools has leapt to the top in the world In the era of planned economy, all industries have a tendency to expand in quantity, but the tool industry has become more prominent. By the end of the 1980s, the basic team consisting of more than 100 key enterprises and fixed-point enterprises in the tool industry had formed an annual capacity of 300 million high-speed steel tools and more than 10 million pieces of measuring tools, ranking first in the world. At the same time, our neighboring tool manufacturing country Japan, the annual output of high-speed steel tools has reached a record high of 120 million pieces. Since then, due to the upgrading of manufacturing industry, the demand for standard tools has decreased, and the output has gradually dropped to 90 million pieces. China's manufacturing industry is not as large as Japan, but tool production is three times that of Japan, and it has clearly reached a dangerous area of ​​excessive expansion. The impact of the expansion of the number of export markets in the last five years, prices have lowered tool. Some enterprises even cut 40%-50%, and the national sales volume has only reached 200 million pieces. More seriously, in the mid-to-late 1980s, due to the optimistic estimation of the market prospects, China's key enterprises of tool backbones not only expanded themselves, but also cultivated a large number of joint ventures to increase production capacity. Later, most of these joint ventures were separated from the parent factory for independent development, and some state-owned enterprise employees set up factories on their own “going to the sea”, which constituted the first batch of tool private and township enterprises in China. These enterprises are flexible in terms of mechanism, and there are no historical burdens of state-owned enterprises. They may have become a new force in the reform and development of the tool industry. But unfortunately, due to the limitations of the talents, technology, equipment, and management level, most of these enterprises are still a number of old ways of expansion, and they are intensifying. In just 10 years, the total amount has soared to 10 100 million pieces, the varieties are concentrated in twist drills, construction drills, woodworking kits, calipers and other low-end products. Although the number is large, sales account for only about 30% of the total domestic market. Although due to brand and quality reasons, these products have not entered the formal manufacturing tool sales system at home and abroad, but have already caused great impact on China's tool export market. Strategic mistakes lead to the development of industry market structural weakness in the second major mistake in the hardware industry development strategy, the transformation of scientific and technological revolution is large and international manufacturing, a large increase wave unresponsive. Did not seize the opportunity to timely improve the structure of China's tool products and services. The overall level of China's tool industry and the gap between foreign countries, after 20 years of reform and opening up, are not narrowing but increasing. This is a serious fact that we have to face. We know that developed countries in the West completed the “post-industrial development stage” in the 1960s and 1970s. In the 1980s, they gradually entered the high-tech industries such as developing information, biology, new energy and new materials. In the era of knowledge economy or new economy, there has been a wave of high-tech transformation of traditional industries. Information technology, automation technology, modern control and management technologies have been rapidly and widely adopted, bringing mechanical product levels and service levels to a whole new level. In this major transformation, the machinery industry has set an unprecedented high standard for its tool products, one of its main processing methods. In summary, it is high precision, high efficiency, high reliability and specialization, the so-called "three high and one special". This kind of requirement has created great contradictions and conflicts with the traditional standardization, generalization, and serial production of the tool industry. In the early 1960s, the new four-roll rolling process of twist drill was developed and promoted. In the early 1980s, it was eliminated in developed countries. In order to catch up with the development requirements of contemporary mechanical processing, the foreign tool industry has made up its mind to aim at the new goal of “three highs and one specialization” and completely change the old development model to a new height. This kind of all-round development and improvement requires a lot of capital investment and intellectual investment. At this time, we have lost the best development opportunities, and some companies with weak strengths are gradually unable to withdraw from the stage. From these developments and changes, it is not difficult to understand that the gap between the Chinese tool industry that has stalled and the rapidly developing foreign tool industry is an inevitable result. In recent years, industry insiders have often complained that the market is weak and sales are not smooth. In fact, the market demand structure is adjusting, the production structure has not been adjusted, and structural weakness has occurred. In this regard, there are figures to prove that only from 1998-2000 statistics, imported tools increased from more than 40 million US dollars to more than 80 million US dollars per year. It can be seen that in the field of high-tech products, market demand is still very strong. To learn Road plight to survive market competition Reflection: no way back, we have to learn a new track in the survival and development of competition in the market. Entering the market economy, the enterprise first gives itself a correct positioning: Where is the advantage of the enterprise? Which objects are suitable for service? How to serve? Correct positioning is the premise of enterprise development, and the purpose is to foster strengths and avoid weaknesses and surpass opponents in competition. In this respect, we must learn from the lessons of the planned economy era. We must be big and comprehensive, small and complete, do everything, and have no advantage. This is doomed to failure in market competition. Starting from the status quo of China's hardware tools industry, it can be said that: in terms of traditional standardization tools, the performance price ratio of China's products is still quite competitive in domestic and international markets. This advantage must be maintained and carried forward, and it is also the capital of our development. But don't make mistakes in blind numbers and chaos. In the modern tools and technical services of the "three high and one special", we have a big gap with the international strong players. However, in the international tool industry, large and strong multinational enterprises are a minority, and thousands of small and medium-sized enterprises still survive and develop. They rely on their expertise and small, specialized, small and strong roads. When China's tool industry transitions to modernization, it must also play its part, starting from a small and specialized stage. In particular, the current large and medium-sized tool enterprises should not overestimate their own strength. In the process of technological innovation and improvement of corporate competitiveness, we must also pay attention to highlighting key points, concentrate on fighting the battle against annihilation, and avoid making mistakes in paving the way and blindly developing. This kind of positioning of the company's seeking truth from facts will instead exert the overall advantages of the whole industry and accelerate the pace of modernization.

Pressure Sensor

Pressure sensor usually consists of a pressure sensor and a signal processing unit for measuring the pressure of liquids and gases. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. According to the working principle, it can be divided into Ceramic Pressure Sensor, diffusion silicon pressure sensor, piezoresistive pressure sensor, sapphire pressure sensor and so on.
