Gestión de Compras has extensive experience in the design, development and manufacture of hot runner systems.


Hot runner systems are feed systems for injection molds which convey molten plastic from the machine nozzle into the cavity.

Hot runner systems are composed of different parts and mechanisms:

Nozzles

Nozzles are the melt delivery system. Nozzles are designed to inject and distribute molten polymer to a number of cavities.

Manifolds

It is a heated melt-distribution system with channels. This structure can be in different shapes as I, H, X, Y or any demanded shape.

Flow control

Valve technology to control the melt flow.

Temperature controller
Connections/Parts

All relevant connections as electrical, resistors, thermocouple...

Hot runners may be classified according to how they are heated. There two main types of hot runner systems:

Insulated runners

This system allows the molten polymer to flow into the runner, and then it is cooled to form an insulating layer of solid plastic along the walls of the runner.

Heated runners

For heated runner systems, there are two designs: internally heated and externally heated. The first is characterized by internally heating. The resistor is placed directly in the melt channel and heats the material from the inside. The second consists on manifold is heated with interior flow passages. The manifold is designed with various insulating features to separate it from the rest of the mould, thus reducing heat transfer.

Hot Runner System Advantages

  • Easier fully automatic operation.
  • No loss of melt.
  • Pressure losses minimized.
  • Increase of mechanical efficiency.
  • Improvement of product quality.
  • Extension of mold life.
  • Shorter cycles.
