What is Precision Metal Stamping?

Compared to ordinary metal stamping, precision stamping requires much stricter conditions.

The precision stamping dies must be designed very precisely, often requiring precise surface hardening treatment. The dies must have good wear resistance and durability to ensure long-term stable production.

The surface quality requirements for precision stamped materials are very high. The material proportions must be correct and consistent, and the surface typically needs to be smooth, scratch-free, and flawless. For sheet metal, strip, or coil raw materials, the material width must be within the specified tolerance range. Common materials used for precision stamping include stainless steel, aluminum alloys, copper alloys, and so on.

For precision metal stamping, good die design and manufacturing, as well as strict control of material quality, are essential to ensure consistent product quality in large-scale production.

Benefits of Using Stamping Parts

Benefits of using other stamping parts include material versatility, tailored properties, and application-specific designs. These components enable innovations across various industries, addressing unique requirements with optimized performance, durability, and cost-effective production, ensuring the success of diverse projects.

Precision Metal Stamping Process

Precision metal stamping is a cold forming method, and it consists of nine processing operations:

Extrusion: The blank is placed in the mold cavity, and pressure is applied to extrude it from the mold gap to form hollow or solid parts.

Curling: The end of the sheet metal is rolled into a nearly closed round head, typically used for processing parts similar to hinges.

Drawing: The sheet metal is pressed into hollow parts of any shape using a die, or further deformed for hollow parts.

Bending: The sheet metal is bent into parts with a certain angle using a die, or re-bent for pre-bent parts.

Flanging: Holes or outer edges of the sheet metal are turned into straight walls using a die.

Bulging: Radial force is applied to the hollow part by a die to expand the local diameter.

Necking: Radial pressure is applied to the mouth of the hollow part by a die from the outside to the inside, reducing the local diameter.

Expanding: Deformation method that enlarges the radial dimension of a hollow or tubular blank at a certain location.

Trimming: Flattening the uneven surface of the workpiece; pressing the already bent or drawn workpiece into the correct shape.

Equipment used for stamping includes manual presses, mechanical presses, hydraulic presses, pneumatic presses, high-speed mechanical presses, CNC presses, and precision presses.
