Automobile seal manufacturing process
Abstract
Automotive sealing strip as an important vehicle spare parts, play connection sealed buffer shockproof, waterproof, dustproof and anti-noise and other important role is to ensure that key components of one of comfort. The graduation project in Zhejiang Xianju Shaped Rubber Boda main task is to seal the company's production line extruders, molding machines, cooling systems, as well as the stamping process flocking process sequence understanding of the company's seal the entire process of production, management products, as well as product development design detailed enough to understand. BYD F3 key is in the hands of the left window sealing pressure of the manufacturing process, in the actual production process to optimize the various processes to reduce production costs and improve the passing rate of the product. And feedback for the car manufacturers of the products come back in good time to make reasonable improvements. Automotive sealing production is a complex process, which both process and materials similar to the characteristics of the process, and discrete processing steps. Mechanical changes, and also makes use of a chemical reaction. In addition to the basic particles of PVC thermoplastic flexible production process, also used the cold metal, welding, surface treatment and other processing means. Overall, the car seal of the manufacturing process, including the three major steps: preparation of raw materials, extrusion process, after the order process.
