Viscosity nylon engineering plastics have many excellent properties, mainly for the automotive parts, mechanical parts, electronic parts, transportation materials, building materials, medical supplies and other aspects of life. 1.1 automobile manufacturing in the automotive industry, high viscosity nylon dominant, specializing in the production cast nylon tube, which is resistant to organic solvents, can produce fuel filter, filter, oil storage tanks and the like. Viscosity nylon has good resistance to impact toughness, use it to produce radiator tank, when cars flying stone impact resistant: viscosity nylon alloy has good heat resistance, not only the quality of a vehicle outer panel light, and forming complex surfaces can not be formed steel; automobile outer panels made from rare earth oil casting nylon tube, but also with metal switchboard for online finishing, in order to improve the vehicle outer panel corrosion resistance and resilience during the collision. Toughness is mainly used for high-viscosity nylon tubing clip, snap, doors, front and rear covers, handles, locks, seat belts fixed hinges, instrument panels, cooling fans, fenders, visor clamp, dust cover and so on. (1) The amount of nylon and sleeve assembly seat after metal interference than some large, over 1 to 1.2% by the amount of interference diameter, Meishan cast nylon tube, so that the bush is pressed into the sleeve housing with the appropriate tension to prevent loose. Generally quiet with the 0.10 ~ 0.15mm, move to fit within 0.5 ~ 0.8mm and range. (2) nylon sleeve and also increase with the size of the shaft, the gap is 0.8 to 1.0% shaft diameter, PA66 cast nylon tube, pressed into the bush after bush can, nylon sleeve shrink still ensure sufficient gap and the shaft with, otherwise the heat generated during operation axle phenomenon. (3) and the seat assembly bush penetration method should be used, must beat hard hit MC901 cast nylon tube, Texas Hongyue sample free online consultation Meishan cast nylon tube by Wang Yue Dezhou Composites Limited.
