Introduction of high strength products:
At present, the factory high strength fasteners are mainly used in automotive engine, transmission, car seat, seat belts, chassis and body parts, such as the installation of the connection. SGM Regal, lacrosse, GL8, Excelle, sail, Nissan sunshine, blue jays, Da Qi, FAW Volkswagen Bora, Tianjin FAW Xiali series, Beijing Benz Cherokee, outlander, application of the models.
The high strength fastening pieces from raw materials began in-depth study, including raw material annealing, cold heading forming conditions, heat treatment process parameters and rolling wire precision and dimensional stability, surface treatment effects, transfer process anti bump and so on. A careful analysis of the impact of the quality of each link.
1 use the axial force instrument to detect the friction coefficient of the fastener, so as to analyze the relationship between the preload and torque of high strength bolts.
2 eddy current flaw detector for high strength bolts internal defects, uneven hardness, mix material for non destructive testing.
3 image method of all sorting equipment for the overall size of the fastener and the surface quality of the whole separation.
The application of triangle rod screw:
The factory is the first for Beijing Jeep Corporation localization development of Cherokee triangle pole tapping products supporting plant, at present the product widely used in cars in Europe and the United States Department of Shanghai GM, Beijing jeep, JMC transit, FAW Volkswagen and automobile assembly, with self tapping self-locking function and assembly without internal thread fit.
Application of punching and riveting bolts:
Flush riveted bolt is a novel and plate connection bolt products, instead of the traditional welding bolt and has the advantages of energy saving, high efficiency, high strength, high reliability advantages. Application in front of Buick series to strengthen the board, block, and other parts of the basin.
Application of heat resistant stainless steel products:
The factory's heat-resistant stainless steel products to take special materials and process production, so that the product at high temperature of 900 degrees, the strength of the same, not oxidation, no deformation; applicable to the engine exhaust system. Currently used in Tianjin FAW full range of engine exhaust system, Dongan MITSUBISHI 4G1, 4G9 series engine exhaust system.
