How to Prolong Mold Punches’ Service Life
Mold punches are workhorses of industrial production, enduring heavy pressure daily. Their condition, often overlooked, significantly impacts production costs and efficiency. Damaged punches can halt production, leading to waste. Here’s how to make them last:
Optimize Mold Design
A good mold design is key. Strengthen the mold structure to increase rigidity. Shorten small mold punches for more strength and add guide sleeves for protection. Set an appropriate gap between components to reduce wear and maintain mold punches quality.
Select and Treat Materials Right
Choose top – quality materials. Cemented carbide suits high – hardness materials, while high – speed steel offers great impact resistance. Follow up with proper forging and heat treatment, like high – temperature quenching and tempering, to enhance durability.
Prioritize Maintenance
Regularly clean the mold surface to reduce friction and wear, then lubricate it. Sharpen punch edges often to keep them cutting effectively.
Refine the Punching Process
Optimize punching parameters such as speed, pressure, and stroke to minimize wear. Use high – precision, high – rigidity presses to reduce stress on mold punches.
Next time you face mold damage issues, try these methods. Create a good working environment for your molds, and they’ll serve you better and last longer.
