Failure modes of cold pier molds and measures to extend their lifespan
Common failure modes:
Wear and tear: The surface of the mold cavity or convex mold exceeds the dimensional tolerance due to long-term friction;
Cracking: Local fragmentation caused by impact loads (such as high material hardness or fast cold pier speed);
Deformation: Improper heat treatment or long-term high pressure can cause the cavity size to increase (such as mold swelling).
Measures to extend lifespan:
Choose higher performance materials (such as powder metallurgy high-speed steel);
Optimize heat treatment process (such as multiple tempering to eliminate stress);
Regular maintenance: Grinding and repairing worn surfaces, replacing vulnerable parts (such as top rods);
Control the cold pier process parameters: avoid overloading (such as cold pier force not exceeding 80% of the allowable stress of the material).
The manufacturing accuracy and material properties of cold pier molds directly determine the quality and production efficiency of cold pier parts, especially in large-scale production (such as automotive fasteners), the stability and wear resistance of molds are the key to reducing costs.
