Springs Are Mechanical Parts That Work With Elasticity
- Jun 26, 2018 -

Springs are mechanical parts that work with elasticity. Generally made of spring steel. Although the spring is small, it is used as a universal basic part. It has a wide range and a variety of types. It is used to control the motion of parts, ease impact or vibration, store energy, and measure the size of force. It is widely used in machines and meters. It covers almost all areas of the national economy. In recent years, the rapid development of China's national economy has also stimulated the rapid growth of China's spring industry. Experts expect this growth will continue. By 2010, the industry's total sales will exceed 4 billion yuan. According to analysis, there are currently five major markets for spring products: transport, daily hardware, instrumentation and electronic appliances, mining and mining accessories, and overseas export markets.

The transportation market has the strongest driving force

The transportation market, including the supply of springs for maintenance and repairs to the automotive, motorcycle, diesel and railway industries, is currently the most important and promising market for the spring industry, with sales close to 40% of the total industry, only the automotive industry. In 2002, there were 7 million suspension springs, 100 million valve springs (including motorcycles and diesel engines), and 1.2 million stabilizer bars. In 2002, the total sales of springs for these industries were more than 1 billion yuan.

In the next 5-7 years, China's auto industry will enter a stage of rapid growth, with an annual growth rate of 15%-25%. In 2003, the demand for suspension springs is expected to approach 10 million, and the demand for stabilizer bars will be 1.6 million. The rapid development of the automotive industry has produced a significant pulling effect on the spring industry, which has become the largest user of the spring industry and has attracted the attention of foreign spring counterparts.

Another major potential market for the spring industry is the railway system. With the deepening of the system reform of the railway system, the gradual opening of the market and the implementation of high-speed railway planning, the vehicle damping system is facing upgrading, and the railway line must be installed with new types of shock absorption and noise reduction. The components will bring huge business opportunities to the spring industry. Some companies have already been listed as high-speed train spring fixed-point units of the Ministry of Railways, and some units are developing rubber-metal composite springs for vibration damping and noise reduction of high-speed railway tracks. At present, the market for the railway system has just begun to open up to the external system. Although the degree of openness is still small, the potential is considerable.

In the next few years, the motorcycle industry will not have much growth, and will continue to maintain the current annual output of 13 million vehicles. The demand for motorcycle shock absorber springs and clutch springs will remain at the level of 50 million and 40 million, and the environment With the increase in demand, the proportion of two-stroke motorcycles has dropped, and the proportion of four strokes has risen, which will increase the number of valve springs.

Strong demand for daily hardware market

The daily necessities industry and the hardware industry include lighters, toys, locks, door hinges, gym equipment, mattresses, sofas, etc. In terms of quantity, the demand for springs is the largest, with hundreds of billions of pieces. The technical requirements are not high and prices are very high. Low, generally produced by small spring plants scattered throughout the country, they have unique advantages in terms of cost, and large spring plants are difficult to compete with them. In recent years, the domestic market has had a strong demand for daily-use hardware products, which has led to the growth of matching springs. As a result, new spring companies have also been born from time to time. In the future, market demand will increase at a rate of 7% to 10% per year. After China's accession to the WTO, the export volume of daily hardware products has increased significantly, and spring demand has been driven. However, due to the influence of international market demand and trade barriers, the international market has its own uncertainties.

Instrument and Appliance Market Starts Recovery

Typical products of instrumentation and electronic and electrical springs such as brush springs, switch springs, camera springs, computer keyboard springs, and instrumentation accessories springs. There are many leaf springs and guide springs in these types of springs. The material and technical requirements of different products vary widely. . In the past few years, the domestic instrumentation, electronic and electrical industries were impacted by imported products and were generally sluggish. The spring manufacturers supporting them were weighed down and have recently recovered and recovered.

Industrial and mineral product market is adjusting

The industrial and mineral products market covers textile machinery from cradle springs to chemical springs, power station switches and hanger springs, bulldozer springs, etc., covering the industrial sectors other than the transportation industry. The material, technical requirements, and processes of the products The difference is huge. The demand for springs is directly proportional to market demand for production materials and the scale of infrastructure projects. It was affected by the industrial structure a few years ago. This market has been in an awkward state and has recently picked up, but it has not yet gotten rid of adjustments. The situation.
