Presentation of the equipment's characteristics

The Greenstone G Automatic Glass Mold Punch Laser Cladding Repair System is specially developed for the precision repair, surface strengthening, and remanufacturing of glass mold punches. Designed for high-temperature and high-wear production environments, the system integrates advanced laser cladding technology, intelligent automation, and high-precision motion control to restore worn punch surfaces and significantly extend service life.

Equipped with a five-axis CNC automation platform, intelligent process software, precision laser cladding heads, powder feeding systems, and customized nozzles, the equipment delivers stable, repeatable, and fully automated repair operations for punches of different sizes and geometries. The system supports high-performance alloy coatings and precision additive repair with excellent dimensional consistency, making it ideal for glass mold manufacturing, mold refurbishment, and surface engineering applications.

Glass mold punches often operate under extreme temperatures, rapid forming cycles, and severe friction conditions, leading to surface wear, corrosion, pitting, and material loss. Traditional repair technologies such as plasma spraying and conventional welding struggle to provide long-term durability and precision. The Greenstone G Automatic Glass Mold Punch Laser Cladding Repair System offers a highly efficient and intelligent alternative for precision mold repair and surface remanufacturing.

The system combines automated CNC motion control, precision laser energy management, and optimized metallurgical bonding technology to improve wear resistance, corrosion resistance, thermal stability, and overall mold service life while reducing repair costs and production downtime.

Advantages of Laser Cladding Technology
  1. Superior Wear and Corrosion Resistance
    Laser cladding forms a dense metallurgical coating layer with excellent hardness, oxidation resistance, and corrosion protection, significantly improving punch durability under high-temperature working conditions.
  2. Precision Repair and Surface Restoration
    The system enables accurate repair of worn or damaged punch surfaces while maintaining dimensional precision and reducing material waste.
  3. Strong Metallurgical Bonding
    The cladding layer achieves excellent metallurgical fusion with the substrate, featuring low dilution rates and high coating reliability for long-term operation.
  4. Low Heat Input and Minimal Deformation
    Compared with conventional welding processes, laser cladding minimizes thermal distortion and heat-affected zones, preserving mold accuracy and stability.
  5. Wide Material Compatibility
    Suitable for cast iron, copper alloy molds, tool steels, nickel-based alloys, cobalt-based alloys, and other high-performance materials used in glass mold production.
  6. High Efficiency and Reduced Production Costs
    High-speed laser cladding and automated process control shorten repair cycles, reduce downtime, and lower mold replacement costs.

Application case analysis

  1. Import the punch digital model into the offline programming software to generate the five-axis cladding trajectory path;
  2. Use the post-processing software to process the trajectory path and import process data and other parameters;
  3. Use the laser cladding machine to automatically mass-produce the punch blanks;
  4. Put the cladding product into the sandbox for insulation;
  5. Perform the final mechanical finishing on the cooled punch to obtain the final punch product.

Application case analysis

The cobalt-based alloy/nickel-based alloy strengthening layer is clad on the surface of the punch workpiece. The strengthening layer is metallurgically bonded to the substrate and has high density. It can significantly improve the workpiece’s high-temperature wear resistance and corrosion resistance, thereby increasing the product’s service life.
