Moldmate couplings are specifically designed for connecting coolant to molds and dies, on injection molding machinery 
in the plastic and die casting industries.Moldmate couplings significantly reduce machine downtime by providing fast 
and easy connection of coolant lines during mold changes.Their short nipples can be recessed below the surface of the 
mold for more efficient storage of molds.Moldmate couplers are avaliable with or without valves in the female half.
Non-valved couplers provide maximum flow for efficient cooling.Valved couplers shut off when disconnected.

Moldmate couplings are designed for a maximum working pressure of 200 PSI.Most thermoplastic and thermoset heat transfer systems have pumps which provide relatively high flow rates at relatively  low pressures.Water and water glycol(anti-freeze) systems usually have capacities ranging from 10 to 40 gpm,with most from 10 to 15 gpm.Normal medial opening pressures are 20 to 60 PSI.However,their flow rates are usually much higher,requiring the total volume of oil to be circulated at least once per minute.
The number of hose connections in a single mold system results in a cumulative pressure drop.Please note the Pressure Drop vs.Flow Rate chart provided,to select the appropriate.
Temperature is another important consideration.Parker moldmate couplings with their standard Silicone seal have a temperature capability of -68℃ to +205℃.Rapid deterioration of the seal and leakage may result if used beyond these limits.
Extemal conditions of temperature,corrosive atmospheres,and other abnormalities may affect coupling performance and must be considered when selection is made. Consult factory with questions.
