3C Electronics

In the precision manufacturing process of 3C electronic products, the punching process directly affects the assembly accuracy and electrical performance of key components such as connectors, shields, housings, and brackets. ZHONGWANGDA (DONGGUAN) PRECISION MOLD CO., LTD. provides various types of precision punching products tailored to the characteristics of 3C industry parts—small dimensions, tight tolerances, and diverse materials (such as stainless steel, copper alloy, aluminum alloy, engineering plastics, etc.). The company does not blindly pursue "maximum" or "fullest" capabilities. Instead, it reasonably matches punch pin material, clearance, and structural style according to customer drawings, samples, and process requirements. For example, when machining micro steel holes on a mobile phone connector shield, burrs can be reduced by controlling the punching clearance; when machining light-transmitting holes on a photoelectric sensor housing, hole position consistency and cross-section smoothness can be ensured. At the same time, ZHONG WANG DA supports bottom scrap clearance hole design to facilitate automatic scrap ejection in progressive dies and reduce manual intervention. For non-standard hole shapes in the R&D stage, the company can provide rapid prototyping to help customers shorten product iteration cycles.

The various precision punching products provided by ZHONG WANG DA can be used for machining structural and functional parts of 3C electronic products, including but not limited to:

• Steel holes, electronic steel holes: Suitable for precision opening on thin-walled metal parts such as mobile phone shields, connector housings, and camera brackets, meeting requirements for small hole diameters and high positional accuracy.

• Optoelectronic holes: Can be used for micro-hole processing on photoelectric sensors, infrared receiver windows, and other parts requiring light transmission or positioning.

• Spring holes, screw spring holes: Suitable for plastic or metal housings of electronic products that need to install micro springs or self-tapping screws, ensuring assembly consistency.

• Bottom scrap clearance holes (bottom blanking): Can be used for automatic scrap ejection in PCB or flexible circuit board molds, reducing manual cleaning frequency.

• Non-standard punching: Customizable for special-shaped holes, stepped holes, and compound holes according to 3C product drawings, meeting rapid prototyping needs of product iteration.

ZHONG WANG DA provides mold design and manufacturing services in coordination with customer product materials (stainless steel, copper, aluminum alloy, engineering plastics, etc.) and thickness, helping to improve stamping efficiency and hole positional accuracy.
