What common punching defects may occur due to improper mold clearance at Manhart (Guangdong) CNC Machine Tool Co., Ltd?

Improper mold clearance may lead to the following common punching defects:
1. Excessive burrs: When the gap between the molds is too large, large burrs will be generated at the edges of the punched parts, which not only affects the appearance quality of the product, but may also affect subsequent processing and assembly.
2. Unfinished cross-section: Excessive or insufficient clearance between molds can lead to uneven and uneven cross-sections of punched parts, resulting in tearing and unevenness. This not only affects the appearance quality of the product, but may also affect its performance and service life.
3. Dimensional deviation: Improper mold clearance may lead to oversized or undersized punched parts, which cannot meet product requirements. Severe dimensional deviations may lead to product scrapping and increase production costs.
4. Accelerated wear of convex molds: If the gap between the molds is too small, it will increase the friction between the convex molds and the concave molds, leading to accelerated wear of the convex molds. This not only affects the accuracy and stability of the punched parts, but may also shorten the service life of the mold.
5. Jamming phenomenon: If the gap between the molds is too small or the convex and concave molds are severely worn, it may lead to jamming during the punching process. This will cause production interruptions, increase the time and cost of maintenance and debugging.
Therefore, reasonable control of mold clearance is of great significance for avoiding punching defects, improving product quality, and reducing production costs. In the actual production process, mold gaps should be reasonably determined and adjusted based on factors such as material properties, thickness, strength, as well as specific production requirements and process conditions. At the same time, it is necessary to strengthen the daily maintenance and upkeep of the mold, timely detect and repair worn and damaged components, and ensure the stability and accuracy of the mold.
