In today's society, with the improvement of people's living standards, automobiles have entered thousands of households. So do you know which parts of the car are made by stamping? Let me introduce you today.

The stamping parts on the car body are roughly divided into cover parts, beam parts and general stamping parts. According to the purpose of use, they can be generally divided into: cover parts, supports, structural reinforcements, supports, frame beams, etc., which can clearly represent the car The stamping parts with image characteristics are automobile panels.

Covers are divided into outer cover and inner cover. They have the characteristics of thin material, complicated shape, large structure size and high precision, high surface quality, and cannot be formed at one time; many beams are included in the inner cover assembly. Such as reinforcement beams for automobile engines, cabs, floors, side walls, etc. Generally, stamping parts are relatively simple in shape, small in structure size, small in deformation, low in dimensional accuracy, fewer processes, simple molds, and small equipment tonnage. No need to form a production line, a single machine can be completed.

Automotive stamping parts often have under-cracking defects: cracking/wrinkle/dark damage/burning/burr/crushing/concave/convex/wave/shortage/stacking/deformation/dimension accuracy out of tolerance/out-of-stock limit.

In order to ensure the product quality of automobile stamping parts, stamping parts must pass the following tests:

Visual inspection: cracks/wrinkles/dark wounds/burns/burrs/crushes;

Physical inspection: Whether the number of punching holes, forming marks, left and right marks, etc. of the stamping parts meet the process requirements;

Hand feel physical inspection: whether there are uneven points on the flat surface and R angle, and the unfavorable defects such as along the concave;

Check the various dimensions of stamping parts with inspection tools.
