Material selection and key process points for processing Brass precision stamped parts

Brass alloy is mainly composed of copper and zinc, and some grades also contain trace elements such as tin. Different proportions directly affect stamping performance and finished product quality. When selecting suitable materials for the Brass precision stamped parts process, key factors such as cost, processability, surface treatment adaptability, weldability, bending performance, tensile strength, usage scenarios, and forming ductility need to be comprehensively considered.

The cost needs to match the project budget, machinability determines production difficulty and efficiency, the surface treatment characteristics of Brass sheet metal stamping affect subsequent appearance and functional upgrades, weldability is related to the reliability of multi-component connections, and bending performance and tensile strength jointly determine the structural stability of materials during forming and use. The final material selection must meet the practical application requirements, while taking into account specific properties such as conductivity, wear resistance, and corrosion resistance.
 

Brass precision stamped parts are processed into target structures using various forming processes, including stamping, punching, deep drawing, and bending. Stamping is used to cut the overall shape of parts, and it is necessary to strictly control the distance between the hole diameter and the hole edge to reduce burrs and avoid secondary processing. Punching is mainly used for processing small holes, cuts, and groove structures, usually completed synchronously with the material cutting process.

Deep drawing is the core process of drawing brass sheets through molds, which can be divided into shallow deep drawing and deep deep deep drawing. The forming depth is determined by the mold cavity. Bending is a key process in forming the angle of the Electrical brass switch socket part, usually carried out after deep drawing. During the operation, the corner radius must be controlled to avoid sharp corners and complex cutting, prevent deformation near the hole position, and ensure the accuracy of the forming dimensions.

Bending is a key step in the formation of Electrical brass press parts for switch sockets, and reasonable process parameters can effectively avoid cracking, deformation, and burrs. In production, it is generally required that the corner radius is not less than half of the thickness of the board to reduce sharp corners and complex cutting; The gap and protrusion width should be about 1.5 times the material thickness, and bending near the hole position should be avoided as much as possible.

The common Cold stamping brass for switch bending methods include air bending, embossing, and priming. The air bending adopts a V-shaped mold, which can adapt to workpieces of different thicknesses; Embossing and backing apply greater pressure in a closed cavity, suitable for bending scenarios with higher precision requirements, ensuring angle stability and controlling rebound.

The customized processing of Relay pin brass terminals relies on specialized tools to achieve force forming, with different tools adapting to different production scales and precision requirements. Bent steel bars are suitable for simple bending operations, forming angles through support and pressure; Strike fixtures are commonly used for manual stamping and can stably apply forming force.

Stamping molds are the core tools for large-scale precision production, divided into single station and multi station structures. With the help of punch heads, composite actions such as material dropping, punching, and forming are completed, which can stably process high-precision contours in batches and meet the continuous production needs of complex Sheet metal brass stamping.
