Features of Transfer Molding Press

Machine main structure

  • Adopt four-column structure with the split structure design between the front auxiliary unit and moving plate;
  • It is suitable for many kinds of de-moulding methods and mould usage;
  • Oil tank, power cabinet and display screen are right located, more back space for molds operation.
  • C frame clamping structure available for 30ton, 50ton and 80ton transfer press

    Advantages of Transfer Molding Press

  • Better products quality,wiith injection piston, rubber was injected into mold after mold close,mold cavity filling more balance, rubber filling more tight
  • Less overflow rubber, less rubber wasted
  • More simple operation than rubber injection molding press
  • More favorable price than rubber injection molding machine

  • Disadvantage

  • Rubber should be weighed before filling to injection barrel
  • Not suitable for rubber material which is sensitive to temperature or the curing temperature is low
