Overview of Punching Process

Punching is a processing method that uses mechanical force to cause plastic deformation of materials (usually metal plates) to form holes or other patterns on the material. The punching process is usually operated using a punching machine, a die and a punch. The specific process includes:

Positioning: Fix the material to be processed on the punching machine.

Punching: Under the action of the punching machine, the punch punches the material into the required hole type or shape through the die.

Removal: Remove the punched material and perform subsequent processing (such as deburring, cleaning, etc.).

Take the air conditioner radiator shell as an example:

Function: The air conditioner radiator shell usually needs to be punched to form ventilation holes on the radiator surface to enhance air circulation and help heat dissipation.

Material: Aluminum plate, stainless steel plate or other corrosion-resistant metal materials are usually used.

Features: The size, shape and distribution of the holes need to be accurately punched according to the design requirements of the radiator to optimize the heat dissipation effect.

Take the ventilation holes in the chassis of home appliances as an example:

Function: The chassis of home appliances (such as washing machines, refrigerators, and air conditioner chassis) need to be punched to form ventilation holes to ensure air circulation inside the equipment and prevent overheating.

Material: Commonly used materials include cold-rolled steel plates, stainless steel plates, and aluminum alloys.

Features: The design of ventilation holes must take into account the heat dissipation requirements and aesthetics of the equipment. The precision and quality of punching directly affect the ventilation effect and the performance of the equipment.
