BRJH Hydro-Circuit Blocks for Cooling Water and Oil

This BRJH hydro-circuit block is used inside injection mold cooling circuits where a stable temperature profile is critical for dimensional control. It routes cooling water and oil through compact internal channels, helping remove heat from steel mold components without creating sharp flow disruptions.

• Automotive and industrial connector molds: Suitable for layouts that require repeatable cooling around core/cavity regions. The optimized flow paths support consistent thermal performance during high-cycle production.
• Large housing molds for machinery: Works well when coolant routing must accommodate mixed thermal loads. The heat-resistant block design supports durability under thermal stress.
• General-purpose thermal management stations: Used in mold systems where switching between cooling water and oil circuits is required. This variant’s BRJH structure is designed for robust operation under demanding conditions.

The provided specifications describe the BRJH hydro-circuit block’s thermal management function, but no specific steel grade, hardness (HRC), or heat-treatment state is included in the available data. As a result, material chemistry (e.g., SKD61/H13 equivalent) and measured wear/toughness trade-offs cannot be stated from the current input.

• Heat resistance: The design is intended to withstand service thermal stress while maintaining stable fluid flow.
• Manufacturing relevance: Hydro-circuit blocks are typically produced to precise internal channel geometry to preserve flow stability and reduce pressure loss.
• Data limitation: If you share the material grade or drawings, hardness, nitriding/quench & temper details, and wear-resistance comparisons can be included accurately.

Select the hydro-circuit length L to match the heated mold region or the desired spacing of cooling/oil ports within your interior cooling circuit design. Available dimensions for this series are L = 50, 80, or 100 mm.

• Match to cavity/core zones: Use the selected L so the internal flow path spans the target area where you want heat removal or stabilization.
• Integrate with manifold/layout: Confirm that the block can be accommodated within your cooling plate thickness and mounting clearances. Choose the next length that covers the required circuit span without forcing rework to the layout.
• Tolerance & fit: Because no tolerance class or interface dimensions are provided in the input data, verify dimensional compatibility against your mold plate/interface drawing before final machining.
• Configurable vs. fixed: L is selectable (50/80/100 mm); other interface dimensions are not provided here and should be confirmed from the product’s technical drawing.
