Hot runner system brand:

MP has designed , built and produced many high quality hot runner moulds . we are experienced in building a variety of hot runner moulds like as follow brand :

MOLD MASTER, HUSKY, HASCO, DME, YUDO, INCOE, THERMOPLAY, SYNVENTIVE

Hot runner advatage:

Hot runners are popular in high production parts , especially with a lot of cavities and the advantages of hot runner moulds are obvious :

  • lower injection pressures
  • lower clamping pressure
  • no runners to disconnect from the molded parts
  • shot size is reduced by runner weight
  • nozzle freeze and sprue sticking issues eliminated
  • cleaner moulding process ( no regrinding necessary )
  • having no runners reduces the possibility of contamination
  • consistent heat at processing temperature within the cavity
  • no runners to remove or regrind , thus no need for process / robotics to remove them
  • cooling time is actually shorter ( as there is no need for thicker , longer-cycle runners )
  • Hot runner disadvatage:

    However hot runner also have some disadvantages , the cost is more expensive than a cold runner , it requires costly maintenance , and requires more skill to operate . Color changes with hot runner moulds can be difficult since it¡¯s virtually impossible to remove all of the plastic from an internal runner system .
