BHydraulics Mold Coolant Line Couplings Hydraulic Quick Couplings Moldmate Series Applications Parker moldmate couplings are specifically designed for con- necting coolant lines to molds and dies, on injection molding machinery in the plastics 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 available with or without valves in the female half. Non-valved couplers provide maximum flow for efficient cooling.Valved couplers shut off when disconnected. Special Order Information Standard seal material is Silicone and is compatible with water and water glycol fluids commonly used in heat transfer systems. Fluorocarbon seals are available for use only with oil-based media and not with water glycol.To specify a Fluorocarbon seal, add the suffix "Y" to the standard moldmate part number, thus: PC206Y. PSIDinDropPressure Selection Guidelines Specifications Moldmate couplings are designed for a maximum working Body Size (in.) 1/4 3/8 1/2 pressure of 200 PSI. Most thermoplastic and thermoset heat Rated Pressure (PSI) 200 200 200 transfer systems have pumps which provide relatively high Rated Flow (GPM) 3 6 12 flow rates at relatively low pressures.Water and water glycol systems usually have capacities ranging from 10 to 40 gpm, with most from 10 to 15 gpm. Normal medial opening Material Temperature Range pressures are 20 to 60 PSI for these systems. Heat transfer Standard Silicone seal -90� to +400�F systems using oil generally operate from 10 to 30 PSI. *Optional Fluorocarbon seal -15� to +400�F However, their flow rates are usually much higher, requiring the total volume of oil to be circulated at least once per * For use with oil based media only minute. Performance The number of hose connections in a single mold system results in a cumulative pressure drop. Please note the Moldmate Series (1/4; 3/8; 1/2") Pressure Drop vs. Flow Rate chart provided, to select the Water Pressure Drop (Straight) appropriate size. 50 40 Temperature is another important consideration. Parker 1/4" Valved 3/8"Valved 30 moldmate couplings with their standard Silicone seal have a temperature capability of -90� to +400�F. Rapid deterioration 20 of the seal and leakage may result if used beyond these limits. 10 8 External conditions of temperature, corrosive atmospheres, 6 and other abnormalities may affect coupling performance and must be considered when selection is made.
