Product Design Attention Points Related to Punching in Stamping Processing

In modern manufacturing, stamping is an efficient and precise method of metal processing that is widely used in automotive, electronics, home appliances and many other fields. When designing products related to stamping, designers need to consider a series of key points of attention to ensure that product performance and production efficiency are maximized.

First, material selection is crucial to product design. Different metal materials have different physical properties such as modulus of elasticity, yield strength and hardness, which will directly affect the life of the mold and the quality of the finished product during the blanking process. For example, high carbon steel is suitable for products that need to withstand heavy loads due to its high hardness, but it also means higher mold wear. Therefore, when selecting a material, designers should not only consider the product's usage needs, but also weigh economy and processability.

Second, next, the geometry in product design is also a big question. The design of punched parts with right angles, sharp angles or small radius bends, although it can meet specific functional requirements, may lead to material rupture, deformation or mold damage. Designers should avoid the design of overly complex geometric shapes, while taking into account the fluidity of the material in the design, leaving enough punching clearance to ensure that the product can be produced smoothly without damaging the mold.

Third, the calculation of punching pressure is a part of product design that cannot be ignored. Excessive punching pressure will lead to excessive compression or even damage to the material, while insufficient punching pressure may cause the material to fail to be cut completely. Designers need to accurately calculate the required punching pressure according to the thickness of the material, shear strength and the required punching area, so as to select the appropriate punching equipment and molds.

Designers need to consider the functionality, aesthetics and economics of the product and work closely with the manufacturing team to ensure that the design is feasible and reasonable. This includes optimizing the overall structure of the product, simplifying the number of components, reducing the difficulty of assembly, and anticipating possible problems and planning solutions in advance.
