Spiral Brass Baffles - Inch XT Technology

Spiral brass baffles are installed inside injection mold tooling to manage internal coolant flow and stabilize mold temperature during high-cycle production. The XT Technology separates a single supply into multiple, separately machined channels, helping direct coolant to the hottest steel regions for more even heat extraction.

• Automotive component connector molds: Use the spiral flow path to promote turbulent coolant movement, which supports consistent cavity temperatures across larger flat areas and reduces thermal imbalance near gates.
• Electronics housings and overmolded assemblies: The multi-channel routing improves distribution around complex features, helping maintain dimensional stability where thin ribs or boss regions experience uneven cooling.
• General mold steelworking for repeatable runs: Pair with the included flush-seal 7/8 taper brass pipe plugs to integrate leak-resistant waterlines and simplify maintenance access.

This variant is suited for designs that require uniform cooling without extensive external plumbing, leveraging XT channel separation for controlled turbulence and distribution.

This product uses brass for the baffle assembly and the included flush-seal pipe plugs. Brass provides good thermal conductivity and is widely used for mold-water channel components where stable heat transfer and machinability are important.

• Manufacturing process: Separate machined waterlines are formed and then assembled into the spiral baffle geometry to establish the multi-channel flow path required by XT Technology.
• Heat treatment: The provided specifications do not state a specific steel grade or hardness/heat-treatment state for the baffle body or plugs.
• Wear/toughness trade-offs: Brass typically offers favorable corrosion resistance in water-cooling circuits but is softer than hardened tool steels; therefore, it is selected for flow-control components rather than structural load-bearing areas.

Compared with hardened steel baffle inserts, brass prioritizes corrosion resistance and uniform thermal behavior in coolant channels over extreme surface hardness.

Select dimensions by matching the baffle’s flow-control geometry to the mold’s internal cooling layout (core/cavity) and to the available plumbing features. Confirm the Plug Size is compatible with your waterline and plug interface: available sizes are 1/8"-27, 1/4"-18, 3/8"-18, and 1/2"-14.

• Overall Length: Choose from 4 ~ 18 in to span the intended heated region along the cavity face.
• Blade Width: Select 5/16", 7/16", 9/16", or 11/16" to fit between surrounding steel features while maintaining the designed spacing to maintain effective channel distribution.
• Blade Thickness: Use 0.057", 0.085", or 0.093" to match the pocket depth and avoid interference with neighboring cooling bores.

Where tight fit is required, ensure your mold pocket and waterline interface follow the exact plug size and taper interface (flush-seal 7/8 taper) to achieve leak-resistant installation. The listed dimensions are configurable within the given ranges; use the closest match to the cavity/core requirements and verify clearance during final CAD checking.
