Supplier's note

  1. Technical Breakthroughs:

    • Material Durability: Stainless steel casing withstands kiln heat, extending tool lifespan.
    • Dual Pump Efficiency: Parallel operation reduces evacuation time by 30% for large molds.
    • Smart Safety Switch: Automatically halts operation under pressure overload, protecting jewelry pieces.

  2. Version Selection Guide:

    • Base Model (4L): Ideal for small-scale workshops or individual jewelers needing quick, lightweight solutions.
    • Advanced Model (6L): Perfect for medium-sized studios handling mid-volume casting tasks.
    • Pro Model (Dual Pump): Essential for industrial jewelers requiring high-speed, large-scale evacuations (e.g., bulk production of hollow jewelry).

With the Pro’s 40% faster evacuation speed, you can process multiple casting molds simultaneously, reducing downtime. Pair its dual pumps with the stainless steel casing to ensure consistent performance in high-temperature environments.
