Die casting mold ejector pin laser cladding strengthening equipment reduces ejector pin fracture faults
Date:2025-10-27 16:04     Source:daokedao     Browse:3

The ejector pin of die-casting molds frequently ejects castings in high temperature environments, which can lead to surface wear, bending, fracture, and other problems, resulting in poor ejection of castings. The traditional ejector pin has a short service life, and laser cladding strengthening of the ejector pin in die-casting molds has become the key to improving mold stability.

The Daokedao laser cladding equipment melts a laser cladding wear-resistant and tough composite coating on the surface of the top pin, with a coating hardness of HRC60 or higher, and good toughness, with a 40% increase in bending resistance. This mold top needle laser cladding equipment has a small heat affected zone during the cladding process, with a top needle deformation of ≤ 0.02mm, ensuring the precision of the ejector.

The service life of the ejector pin processed by the Jingdao Kedao laser cladding equipment is extended by 3-4 times, the fracture failure rate is reduced by 80%, and the stability of the mold ejection system is improved by 50%. The equipment supports batch processing of ejector pins of different diameters and lengths, with high processing efficiency and the ability to quickly strengthen ejector pins, providing a guarantee for the continuity of die-casting production.
