Mold Design and Durability
Challenge: The mold is the core of perforated sheet production. Improper design can lead to uneven or irregular holes. Additionally, the mold's wear resistance directly affects production efficiency.
Solution: Use high-strength materials to manufacture molds and perform surface heat treatment to extend their service life.
Material Thickness Limitations
Challenge: For thicker materials, the punching equipment may not be able to handle the pressure, leading to mold damage or the inability to form the product.
Solution: Choose suitable equipment based on the material thickness and adjust the mold gap accordingly.
Hole Spacing and Accuracy
Challenge: Maintaining consistent hole spacing across large areas of material requires high precision. Vibrations from equipment or shifting of the material can cause deviations.
Solution: Use CNC punching machines or laser cutting equipment to improve accuracy and reduce human error.
Edge Burr Issues
Challenge: During punching, burrs can form along the edges of the material, affecting the appearance and safety of the final product.
Solution: Optimize the punching process, increase maintenance frequency for punch heads, and perform deburring treatments after punching.
Material Deformation or Cracking
Challenge: Certain materials may deform or crack due to stress concentration during stamping, especially brittle materials.
Solution: Preheat the material before punching, and choose appropriate punching equipment and process parameters.
Low Efficiency in Large Area Punching
Challenge: Punching large-sized perforated sheets can be time-consuming, resulting in decreased efficiency.
Solution: Use continuous punching equipment or combine molds for faster punching.
Surface Treatment and Protection
Challenge: Improper surface treatment may reduce the corrosion resistance or damage the appearance of the finished product.
Solution: Choose the appropriate surface treatment methods (such as hot-dip galvanizing, powder coating, etc.) and ensure a clean processing environment and strict process control.
Deformation Caused by Heat Treatment
Challenge: When certain materials undergo heat treatment (e.g., post-galvanizing), thermal expansion may cause warping or deformation of the material.
Solution: Control the temperature and cooling speed appropriately, and improve fixture design to reduce deformation.
Although these obstacles are difficult to completely avoid, through technological improvements, equipment upgrades, and strict production management, their impact can be minimized.
