Customized Sheet Metal Stamping Parts For Automotive Spare Part

What are the requirements for the performance of automobile stamping parts:

1. Car compartment parts

The shape of the parts of the car compartment is not too complicated, and most of them use the roll forming process, which has certain requirements on the formability, rigidity, corrosion resistance and weldability of the material. Generally, high-strength steel plates with good shape properties and weldability are used. Usually, high-strength steel plates and ultra-fine grain steels with a strength level of 300-600 MPa are used.

2. Car cab parts

Most of the car cab parts are cover parts, with complex shapes and complex forming, but the force is not large. Using the mold forming process, the forming performance of the material has become the main contradiction. Therefore, the material is required to have formability, tension rigidity, and extensibility. , dent resistance, corrosion resistance and weldability, etc. When designing products, the steel plate varieties are usually selected according to the stress and shape complexity of the plate parts.

Generally, low-carbon cold-rolled steel sheets and ultra-low carbon cold-rolled steel sheets with excellent drawing properties are selected. In recent years, phosphorus-containing cold-rolled steel sheets with excellent formability and higher strength, high-strength cold-rolled steel sheets, cold-rolled dual-phase steel sheets, bake-hardening cold-rolled steel sheets, ultra-low carbon steel high-strength cold-rolled steel sheets, and other Various types of steel plates, such as coated steel plates, tailor-welded steel plates and TRIP steel plates, are also widely used in vehicle body parts such as door outer panels, door inner panels, door reinforcement panels, roof covers, trunk lids and bumpers.

3. Auto frame parts

The frame, the middle plate of the carriage and some parts used for support and connection are all important bearing parts, and most of them adopt the mold forming process, which requires the material to have high strength and good plasticity, as well as fatigue durability and collision energy. Absorption capacity and weldability, etc., generally use high-strength steel plates, ultra-fine grain steel plates (strength level of 300-610MPa) and ultra-high-strength plates (strength level of 610-1000MPa) with better formability.
