BFPT Brass Baffle Boards with Tapered Screw Plugs

BFPT-style baffle boards are used inside injection molds to stabilize temperature control by managing coolant flow. Their baffle geometry reduces turbulence and helps maintain a more uniform hydraulic path, which is especially valuable when consistent cavity thermal behavior is required.

• Automotive connector and housing molds: Install baffle boards with tapered screw plugs in channels that experience variable flow. The tapered plug mounting improves alignment and helps keep the flow-path stable across repeated thermal cycles.
• Electronics enclosure molds: Use the controlled-flow design to reduce hot spots near thick-to-thin transitions. Brass plus white zinc plating supports reliable operation in industrial cooling environments where corrosion resistance matters.
• General industrial molded parts: The “blank” BFPT type is suited to applications needing consistent hydraulic performance without adding complex channel features.

This product uses a brass baffle board body with white zinc plating. Brass provides good machinability for forming precise baffle features, supporting reliable installation in mold cooling assemblies.

• Corrosion resistance: White zinc plating improves resistance to corrosion in typical mold cooling water environments.
• Wear and service behavior: Brass baffles are generally chosen when stable flow control is prioritized over extreme abrasive wear.
• Heat treatment: No specific heat-treatment process or hardness value is provided in the supplied specifications; therefore, detailed HRC guidance cannot be stated for this exact variant.

When comparing materials for baffle plates, engineers often choose steel for higher mechanical/abrasive resistance, while brass variants like this one are selected for corrosion behavior and manufacturability where abrasive conditions are limited.

Selection is driven by matching the baffle width A and the L length span to the available interior cooling space. Available A values are 6, 8, 9, 10, 12, 14 mm. Available L ranges are 30–200 mm, 30–250 mm, and 30–300 mm depending on the configuration.

• Match cavity thermal needs: Use a width and length that cover the intended restriction/flow-guiding area so the baffle effectively reduces turbulence in the coolant path.
• Check installation clearances: Confirm that the tapered screw plug mounting fits the surrounding channel geometry and that the baffle does not interfere with flow.
• Tolerance/fit: The provided data lists size ranges only; no tolerance values are specified. In practice, verify fit against your cooling plate/channel machining tolerances and plan for standard assembly clearance.

Pick the configuration whose L maximum meets the channel length requirement while using the closest A to the available baffle mounting width.
