  • Easy Color / Material Change – special corner and inlet design reduces downtime during material shifts.
  • Durable Construction – materials and components designed for high-performance resins and continuous cycles.
  • Low Maintenance – modular design allows quick servicing and part replacement.

Types of HotMOLD Manifolds

Inline Manifolds

  • Straight, balanced design for direct, uniform flow.
  • Ideal for multi-cavity, symmetrical molds.
  • Ensures consistent part weight and quality across all cavities.

Offset Manifolds

  • Designed for complex, asymmetrical mold layouts.
  • Flexible routing of melt flow while maintaining balanced distribution.
  • Suitable for automotive, large parts, and specialty components.

Key Features of HotMOLD Manifolds

  • Uniform filling improves molding quality and reduces defects.
  • High-density heater integration ensures reliable heating without cold spots.
  • Optimized for various resins – engineering plastics, transparent, and heat-sensitive materials.
  • Convenient maintenance with easy access and modular design.
