Special couplings
Mold Making
The Nitto Kohki mold-making Cupla are designed specifically for the cooling and tempering circuits of injection and die-casting moulds. The compact Mold and Hot Water series connect water and tempering-medium lines at the mould quickly, tightly and almost spill-free - at temperatures up to about 120 °C and pressures up to around 1.5 MPa.
The space-saving, double-shut-off design minimises media spillage during mould changes and keeps the machine and workplace clean. Brass and stainless-steel bodies with temperature-resistant seals ensure long service life in continuous mould-tempering operation.
