The Application of Automobile Seal Strip Develops Rapidly

The sealing performance of automobile seals is an important indicator of the quality of the entire vehicle, and silicone single wire seal is one of the important parts that determine the quality of this index. Doors, windows, engine compartments, trunks and other body parts to fill the gaps between body parts, with shock absorption, waterproof, dustproof, sound insulation, decoration and other functions, to maintain the crew and the vehicle. There are many ways to classify automotive seal products, usually according to the name of the device part (component), the variety of materials, the number of composite materials, working characteristics and other factors to stop the classification.

Among them, the classification according to the designation of device parts (components) is a common method. Door and window sill inner and outer seals, side window seals, sunroof seals, roof cover seals, trunk (luggage) seals, etc. With the gradual recovery of the international economy, the export demand for auto seals will increase year by year. After experiencing the blowout market in 2009, the auto seal industry has ushered in a period of rapid development. Sealing strips began in 2009, especially in the second half of the year, and major suppliers clearly felt a serious lack of their own production capacity.They participated in the expansion of production capacity and activated automobile seal strip equipment manufacturing enterprises for a time. Equipment orders, feel the difficulty and importance of delivery. However, when it comes to increasing production capacity, we must not only look at the 100,000 anxieties in front of us, but should separate and improve the labor consumption rate, quality improvement, product structure promotion, technological progress and other factors to comprehensively enhance the overall production capacity of enterprises.

Automotive Connector Seal

Application of automotive connector seal

(1) Sealing strip non-continuous vulcanization method (after cutting the extruded rubber strip to a certain length, put it in a vulcanization tank for vulcanization, and put the extruded rubber strip semi-finished product into the model for vulcanization)

(2) Sealing strip continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method, etc.). A. Microwave continuous vulcanization composite sealing strip: Microwave vulcanization technology is a production technology that was applied after the foreign energy crisis in the 1970s and has been widely promoted. The use of microwave continuous vulcanization technology can not only produce composite rubber strips made of metal core, solid core rubber and sponge rubber, but also is superior to other continuous vulcanization methods in terms of energy saving and working efficiency. This technology is recognized by the world as a process for producing extruded products. The characteristic of microwave heating is that the heat is directly generated in the object to be heated, instead of being input from the outside as usual. This not only generates heat quickly, but also is evenly distributed, which is conducive to improving product quality and greatly shortening the time used for heating. B salt bath continuous vulcanization sealing strip: salt bath vulcanization uses a salt bath system containing nitrite, which has a greater environmental pollution and has been gradually eliminated. C. Hot air vulcanization sealing strip: hot air vulcanization has developed to strong wind type vulcanization, that is, high temperature and high speed hot air vulcanization (Tmax: 450 ° C and Vmax: 60m / s) can also achieve the effect of flame pretreatment, sealing The security is greatly improved.
