Supplier's note

  1. Three Technical Breakthroughs:

    • Silicone Lining: Reduces demolding friction by 40%, preventing concrete damage.
    • Fiberglass Reinforcement: Enhances mold lifespan by 2x compared to traditional plastic molds.
    • Rubber Resin Hybrid Base: Offers 25% better shock absorption for complex sink shapes.

  2. Optimal Version Selection:

    • Base Model: Ideal for occasional use (e.g., DIY enthusiasts).
    • Advanced Model: Best for small-scale manufacturers needing repeatable, custom sink production.
    • Pro Model: Professional contractors benefit from its heat resistance (e.g., commercial kitchen sinks) and compatibility with high-strength concrete mixes.

With the Pro Model’s 150°C tolerance, you can safely cast heat-resistant concrete sinks for outdoor use. Pair its carbon-reinforced structure with thicker silicone lining to ensure flawless demolding even in complex designs.
