Description

Technical Field

[0001] This utility model relates to the field of automotive steering wheel processing technology, and in particular to a special fixture for automotive steering wheel processing. Background Technology

[0002] The manufacturing of automotive steering wheels is a complex and precise process, typically involving the following key steps: First, selecting suitable materials, such as high-quality leather, wood, or synthetic materials, ensures the steering wheel's durability and comfort. Next, mold design and manufacturing are carried out; the precision of the mold directly affects the steering wheel's appearance and feel. Then, the material is molded into the basic shape of the steering wheel using injection molding or die casting. After molding, fine grinding and polishing are performed to remove burrs and unevenness, ensuring a smooth surface. Finally, assembly is carried out, including the installation of components such as multi-function buttons and airbags.
