Custom Manifolds



After careful engineering and compiled field experience in hot runner systems, Melt Design has fully designed it's Ultraflow™ Hot Manifold System.

It is offered in system components or completely assembled, prewired tested and ready-to-bolt-on system.

Melt Design has fully designed it's Ultraflow™ Hot Manifold System for their hot runner systems.Its unique features offer the following unmatched benefits:


  • MDi manifolds are uniquely balanced in that in addition to uniform flow channel distance balancing, MDi flow channels are also balanced to MATERIAL flow characteristics

  • One piece solid manifold that only requires one control module to operate

  • Open pipeline flow channels to insure same flow conditions for all manifold exit ports

  • Reflector plates on both sides reduce heat radiation

  • Easy clean up or color changes by simply purging an open mold

  • Constructed from hardened tool steel for better heat response.

  • Replaceable heating elements on both sides reduce mold downtime and maintenance costs

  • Existing conventional molds can easily be converted to hot runner molds

  • Accepts all Melt Design gating bushings

  • Thin manifolds for either single face or stack molds for overall thinner molds.
