Hydraulic Quick CouplingsMold Coolant Line CouplingsMoldmate SeriesApplicationsB HydraulicsParker moldmate couplings are specifically designed for connectingcoolant lines to molds and dies, on injection moldingmachinery in the plastics and die casting industries.Moldmate couplings significantly reduce machine downtimeby providing fast and easy connection of coolant lines duringmold changes. Their short nipples can be recessed below thesurface of the mold for more efficient storage of molds.Moldmate couplers are available with or without valves in thefemale half. Non-valved couplers provide maximum flow forefficient cooling. Valved couplers shut off when disconnected.Special Order InformationStandard seal material is Silicone and is compatible withwater and water glycol fluids commonly used in heat transfersystems. Fluorocarbon seals are available for use only withoil-based media and not with water glycol. To specify aFluorocarbon seal, add the suffix “Y” to the standardmoldmate part number, thus: PC206Y.Selection GuidelinesMoldmate couplings are designed for a maximum workingpressure of 200 PSI. Most thermoplastic and thermoset heattransfer systems have pumps which provide relatively highflow rates at relatively low pressures. Water and water glycolsystems usually have capacities ranging from 10 to 40 gpm,with most from 10 to 15 gpm. Normal medial openingpressures are 20 to 60 PSI for these systems. Heat transfersystems using oil generally operate from 10 to 30 PSI.However, their flow rates are usually much higher, requiringthe total volume of oil to be circulated at least once perminute.The number of hose connections in a single mold systemresults in a cumulative pressure drop. Please note thePressure Drop vs. Flow Rate chart provided, to select theappropriate size.Temperature is another important consideration. Parkermoldmate couplings with their standard Silicone seal have atemperature capability of -90° to +400°F. Rapid deteriorationof the seal and leakage may result if used beyond theselimits.External conditions of temperature, corrosive atmospheres,and other abnormalities may affect coupling performance andmust be considered when selection is made.
