Seals are widely used in almost all industries, so their varieties are particularly diverse. It can be roughly divided into three categories, namely rubber and plastic seals, mechanical seals and flexible graphite seals. There are fewer mechanical seals and flexible graphite seals in the construction machinery industry, and more than 80% are rubber-plastic seals. Therefore, this article will focus on rubber and plastic seals. Let us look at the current status and development of mechanical seal technology.
The development history of China's construction machinery seal technology can be roughly divided into three stages.
The first stage was the beginning of the stage industry (1960 ~ 1980). This is also the period when China's construction machinery initially developed. With the gradual formation and development of the construction machinery industry, the sealing technology and seal industry supporting construction machinery have also gradually formed and developed. During this period, China's construction machinery seals were mainly rubber.
The second stage is the initial development period (1981 ~ 1990). During this period, China began to focus on the construction of the national economy. The speed of the construction of the national economy gradually accelerated, which led to the development of various industries such as construction machinery, and the demand for basic components such as seals increased rapidly. This period is also the period of China's reform and opening up since 1978. Seals and sealing technology have begun to enter China. Since then, construction machinery seals have mainly developed from rubber seals to rubber and plastic seals.
The third stage is the period of rapid and comprehensive development (1991 ~ present). This period is China's "Eighth Five-Year" and "Ninth Five-Year Plan" years of planned construction, and also the high-speed development period of China's construction machinery, automotive, and motorcycle industries, and this also puts forward higher requirements for quality.
Whether it is asbestos, graphite and other non-metallic materials, we are a large producer. Many countries lack this resource, and we can produce more good quality seals.
At present, seals are still labor-intensive products, and Chinese manufacturing costs are low. 60% of current seal competition depends on price factors. In the domestic market, this phenomenon of host supporting (OEM form) is already obvious, especially in the international market. With the further deepening and improvement of domestic reforms. The role of price in the maintenance market is becoming increasingly apparent.
At present, the marketing of the domestic market for seals is mainly dependent on interpersonal relationships. We are blessed with the advantages of time and harmony. We have many advantages under the same quality conditions in the domestic market. From the perspective of market competition, with these three advantages, we can embark on the road to competition.
We firmly believe that China's sealing product industry will become better and better. We are committed to providing quality seals for domestic and foreign customers. If you have any needs, please contact us in time.
