What are stamping parts

Stamping parts are automotive parts that deform metal sheets through the stamping process to obtain a specific shape, size and performance. These parts can be used directly for automotive assembly, or after stamping can be further processed (such as welding, painting and machining) to meet specific requirements. Stamping parts usually have the characteristics of thin, uniform, light and strong, which is more advantageous than castings and forgings. Burrs generated in the stamping process are difficult to avoid, but by optimizing the process conditions and improving the manufacturability of the parts can reduce burrs.

How to repair the wheel hub scratch

The repair methods of the wheel hub scratch include: 1. Wipe around the scar with paint diluent to remove dirt; 2. Use a toothpick to remove the dirt on the deeply scratched part; 3. Use the tip of a brush to coat the finishing paint, and after the paint dries, it shrinks slightly; 4. After drying for a week, apply soapy water to make the surface smooth, and apply water-resistant paper with soapy water to make the surface smooth surface; 5, it can be polished with car-specific sanding paper; 6. Wipe the wheel hub with clean linen; 7. Repair with car-specific scratch repair paint.

What if the brake drum temperature is too high

The solutions for excessive brake drum temperature include: 1. Open the water drench to reduce the temperature of the wheel hub; 2. Stop and rest and wait for the brake drum to cool down naturally; 3. Repair the brake cylinder, poor oil return will cause brake drag; 4. Replace the brake drum spring

The working principle of the brake drum

The working principle of the brake drum is to make the friction lining rub against the inner side of the brake drum through a hydraulic device to achieve the braking effect. The brake drum is mainly composed of brake wheel cylinder, brake shoe, brake drum, friction lining, return spring and other parts. When the brake pedal is stepped on, the piston of the brake master cylinder is pushed to move, and then pressure is generated in the oil circuit. The brake fluid transmits the pressure to the brake drum, so that the friction lining contacts the brake drum, generating friction, and slowing the vehicle Or stop. The brake drum is mostly used to brake the rear wheel and parking brake with relatively small load.

What's the difference between plastic and nylon

Nylon and plastic are both synthetic materials, but there are some key differences between them. Nylon is often used in gears, bushings and plastic bearings because of its low coefficient of friction. It is also widely used in clothing, reinforcement of rubber materials (such as tires), ropes, and plastic parts on vehicles and mechanical equipment. Plastics, by contrast, are a broader category that includes multiple materials such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and so on, each with its own specific application area.

What's a flange

Flange, also known as flange, is a common mechanical connection component, often used in pipeline engineering and mechanical equipment. It is a disk-shaped metal body with fixed holes distributed around it for connection with other parts or pipes. Flanges are manufactured in accordance with the dimensions and tolerances produced by national standards to ensure that standardised flanges can provide stable performance and adequate safety in a variety of application scenarios.
