What Is The Process For Stamping The Sheet Metal For The Wall Mount Brackets?

The sheet metal stamping process of the wall mount bracket uses a press and a die to deform or separate the metal sheet and trim and deburr‌ the formed parts.

First, select the appropriate sheet and calculate the material utilization rate. The following is a reference for material selection.

Stainless steel is recommended for wet and corrosive environments. Carbon steel with surface treatment is recommended for mass production to reduce costs.

The metal sheet goes through punching (punching), bending (bending angle) and blanking (cutting shape) steps in sequence. Use a punch to punch mounting holes or lightening holes on the blank. The flat plate is partially bent into a specific angle, such as a 90° shelving brackets, by extrusion of the upper and lower dies. Complex curved surfaces are pressed out with concave and convex contours through the die. The efficiency of multi-station progressive dies is as high as dozens of brackets per minute, because it can continuously complete punching, bending and blanking in one set of dies.

Finally, the metal shelf bracket is post-processed, trimmed to remove burrs, and surface treatment methods such as galvanizing for rust prevention and plastic spraying beautification are used to ensure the smooth surface of the bracket and improve durability. The advantages of sheet metal stamping are light weight, high strength and low cost, and are suitable for fields such as electronics and automobiles.

Manufacturers of sheet metal stamping wall shelf brackets in production may face the following problems: precision small hole punching will cause accelerated wear of the die, and the price of complex die is expensive, up to hundreds of thousands of yuan. Our solution is to mass-produce hundreds of thousands of pieces to spread the cost, or use carbide insert molds to extend their lifespan.
