Fluid Port Connectors

Fluid port connectors are critical interface components that securely attach fluid supply and return lines to the thermal management plates used in casting molds. They ensure leak-proof connections for coolant or heating fluid circulation, enabling precise temperature control during metal casting processes. These connectors are designed to withstand the demanding conditions of die casting and permanent mold casting, where thermal management is essential for product quality and cycle time. They are available in configurations that accommodate various pipe sizes, thread types, and sealing materials, allowing integration into existing mold designs. The connectors are manufactured from materials such as stainless steel, brass, and high-temperature plastics, with body material options like 316L stainless steel for corrosion resistance. They feature operating pressures from 1.0 to 1.6 MPa, nominal diameters from DN15 to DN50 (per ISO 6708), and connection threads from G1/4 to G2 (BSPP per ISO 228-1). The temperature range spans -40°C to 120°C, suitable for both hot and cold mold media. Seals are made of FKM (per ASTM D2000) to resist oils and coolants. Leakage rates are ≤0.01 mL/min at rated pressure with water, and flow coefficients range from 2.5 to 15 Cv. Weights vary from 0.2 to 2.5 kg depending on size and material. Surface finish is Ra≤0.8 μm (per ISO 1302) to reduce fouling. These connectors are used in casting molds to connect external fluid systems to internal channels within thermal plates, ensuring efficient heat transfer. They are selected based on operating pressure, temperature, fluid type, and connection requirements. Verification of model-specific values and compliance with standards should be confirmed with the legal manufacturer or supplier.

Fluid port connectors create sealed mechanical interfaces between fluid lines and thermal management plates using threaded, flanged, or quick-connect mechanisms. They maintain pressure integrity while allowing fluid to flow between external systems and internal plate channels for heat transfer. The connector body is typically made of 316L stainless steel, with FKM seals to prevent leaks. The threaded connection (BSPP) ensures a leak-free seal when properly torqued. During operation, coolant or heating fluid enters through the connector, flows through the plate's internal channels, and exits via another connector, enabling precise temperature control. The design must accommodate thermal expansion and vibration while maintaining a leak-proof seal over the specified pressure and temperature ranges.
