Metal Stamping Parts in Automotive Manufacturing

Metal stamping parts are indispensable components in automotive manufacturing, accounting for about 70%-80% of the total weight of a vehicle. They are used in various car parts, including body panels, chassis, engine hoods, doors, windows, and seats.

1. Materials for Automotive Stamping Parts

The most common materials for automotive stamping parts are steel, aluminum, and magnesium alloys.

Steel: Steel is the most widely used material for automotive stamping parts due to its good strength, stiffness, and corrosion resistance. Common types of steel include cold-rolled steel sheets, hot-rolled steel sheets, and galvanized steel sheets.

Aluminum: Aluminum offers excellent lightweight properties, which can effectively reduce the overall vehicle weight. Common aluminum alloys include 5000 series, 6000 series, and 7000 series.

Magnesium alloy: Magnesium alloy is even lighter and stronger than aluminum, but it comes with a higher price tag. Common magnesium alloys include AZ31, AZ61, and AM60.

The main processing technologies for automotive stamping parts include blanking, drawing, bending, fine blanking, and flanging.

Blanking: Blanking is the process of stamping metal sheets into parts with the desired shape and size.

Drawing: Drawing is the process of stretching metal sheets into parts with the desired shape and size.

Bending: Bending is the process of bending metal sheets into parts with the desired shape and size.

Fine blanking: Fine blanking is the process of stamping metal sheets into parts with complex shapes and high-precision dimensions.

Flanging: Flanging is the process of folding the edges of metal sheets into the desired shape and size.

Automotive stamping parts are widely used in various car parts, including:

Body panels: Body panels refer to the outer surface of the car body, including the roof, side panels, front fenders, rear fenders, engine hood, and trunk lid. The main functions of body panels are to protect the occupants and internal components and meet aesthetic requirements.

Chassis: The chassis is the load-bearing part of the car, including the frame, front axle, rear axle, suspension, and braking system. The main function of the chassis is to support all the components of the car and withstand various loads during driving.

Engine hood: The engine hood is the cover over the engine, and its main function is to protect the engine from dust, water, and debris.

Doors: Doors are the entrances and exits of the car, and their main function is to allow occupants to enter and exit the vehicle.

Windows: Windows refer to the car door windows, rear windows, and sunroofs. The main functions of windows are to provide visibility, ventilation, and daylighting.

Seats: Seats are the seating arrangements in the car, and their main function is to provide a comfortable riding environment.

With the continuous development of automotive manufacturing technology, automotive stamping parts will also develop in the following directions:

Lightweight: With increasing demands for energy saving and emission reduction, lightweight automotive stamping parts will become a key development direction.

High strength: With growing requirements for car safety and performance, high-strength automotive stamping parts will become a major development direction.

Precision: With the advancement of processing technology, the precision of automotive stamping parts will be further improved.

Intelligence: With the development of intelligent manufacturing technology, intelligent automotive stamping parts will become a significant development trend.

Automotive stamping parts are a crucial foundation for automotive manufacturing, and their development level directly affects the quality, performance, and cost of vehicles. With the continuous progress of automotive manufacturing technology, automotive stamping parts will also move towards lighter, stronger, more precise, and more intelligent directions.
