Nylon sleeve processing process is generally a single fan block combined processing, or processing the workpiece into a cylinder, and then cut. If the blank is manufactured by a single piece, because the mold processing is difficult and the casting technology is not good, the blank can only be cast as a cuboid, the blank component is large, will make the nylon axle sleeve external cost increase, other combination processing table circle, need to be respectively as two pieces of car table circle tooling, very difficult.
Nylon sleeve has a higher melting point, but its melt fluidity is very good, very simple filling cross forming. The fluidity of polyamide is that the viscosity decreases little when the shear rate increases. However, the change of melt apparent viscosity with temperature is obvious, especially for nylon 66 and nylon 6. Therefore, a reverse ring is generally installed at the front end of the barrel. To avoid backflow.
Choose nylon axle sleeve raw materials: the primary consideration is to use the size of the road, obstacles, the use of residual materials on the site (such as iron filings, grease), the environmental conditions and the weight of the wheel can carry, and other different conditions to decide the choice of suitable wheel raw materials. For example, rubber wheels are not resistant to acids, oils and chemicals, whereas POLYURETHANE wheels, high strength POLYURETHANE wheels, NYLON BUShing, steel wheels and high temperature wheels are suitable for different special conditions.
