Causes of Larger Burrs in Perforated Plates

Perforated Plates will inevitably have some burrs after production. Generally, if you touch the back of the Perforated Plate and the burrs are not too sharp or noticeable, they are usually within a reasonable range. However, if the burrs exceed this range, the Perforated Plate is considered a defective product. Below is a simple analysis of the common causes of larger burrs in Perforated Plates:
1. Punch Pin Issues: Perforated Plates are produced by continuous punching on CNC punching machines using alloy punch pins. The sharpness of the punch pin directly affects the size of the burrs on the back of the Perforated Plate. The dulling of the punch pin is the primary factor.
2. Punch Head Faults: The punch head is used to fix the punch pin. If the punch head is severely worn, it can cause improper installation of the punch pin, thereby affecting the burrs on the Perforated Plate.
3. Bottom Die Clearance: If the clearance between the bottom die and the punch pin is too large, it will result in larger burrs on the Perforated Plate.
In addition to production-related factors, burrs may also be caused during actual use due to the following reasons:
1. Environmental Factors: Perforated Plates exposed to high levels of acidity or alkalinity may undergo changes when exposed to metal debris or liquids, which can lead to the formation of burrs.
2. Human Factors: Burrs may also result from manual scraping or external impacts. Therefore, it is crucial to maintain and protect the Perforated Plates during use.
Solutions:
1. Enhance Operator Expertise: When punch pins become worn to a certain extent, they should be promptly repaired to prevent burrs from becoming too large.
2. Regular Mold Inspection: Regularly check the molds. If the mold is severely worn, it should be repaired or replaced to maintain consistent production quality.
