Application Scenarios

Core Production Features

• High‑Strength and Wear‑Resistant Materials

   

  High‑hardness alloy steels (such as Cr12MoV, SKD11) are preferred for their excellent tensile strength, impact resistance, and wear resistance. They can withstand high‑frequency impacts during mold operation and clamping forces, preventing deformation, fracture, or wear.

   

  Heat treatment processes including quenching, tempering, and carburizing are applied in production to further enhance hardness and wear resistance, ensuring long service life.
   
• High‑Precision Positioning Performance

   

  The positioning accuracy of fasteners directly affects molding precision of molds and positioning accuracy of tooling and fixtures. Dimensional and geometric tolerances are strictly controlled to ensure no deformation or loosening after repeated clamping.

   

  High‑precision machining equipment and coordinate measuring machines (CMMs) are adopted to guarantee compliance of screw length, diameter, thread precision, and other indicators. Thread structures are optimized to improve positioning stability.
   
• Quick Changeover and Anti‑Loosening Design

   

  In response to quick changeover requirements of molds and tooling, non‑standard specifications and quick‑release structures (e.g., quick‑release bolts, elastic locking mechanisms) are used to improve changeover efficiency and reduce production downtime.

   

  Anti‑loosening structures (e.g., locking nuts, anti‑loosening washers) are designed to avoid loosening during mold operation or tool clamping, ensuring production safety and product quality.
   
• Adaptation to Complex Working Conditions

   

  Molds and tooling may be exposed to cutting fluids, high temperatures, and other harsh environments. Fasteners are required to have certain corrosion resistance and high‑temperature resistance.

   

  Anti‑corrosion surface treatments (such as galvanizing, chrome plating) are applied, and high‑temperature resistant materials are selected to maintain stable mechanical properties under high temperatures.
