WHP Type Thermal Conductive Pipes for Cooling Mold

This thermal conductive pipe variant is designed for mold interior cooling where stable cavity temperature directly impacts cycle time and part consistency. It is commonly applied in automotive connector and bracket injection molding lines, supporting uniform cooling around fine features to reduce thermal gradients during ejection.

It also fits small housings and consumer electronics enclosures that require compact, reliable cooling circuits. The compact outer diameter options (2 to 8 mm) allow engineers to route temperature-control lines in tight mold layouts without excessive drilling or obstruction.

For industrial heat-exchange tooling and auxiliary thermal systems, the corrosion-resistant construction helps maintain heat-transfer performance in long-running production environments where coolant chemistry can vary.

• Use it in cooling channels/circuits to maintain consistent mold temperature.
• Select the smaller OD variants for tight mold geometries and fine cooling layouts.
• Choose longer L dimensions (35 to 225 mm) to match local manifold-to-run spacing.

The provided specifications focus on dimensional ranges and application intent; a specific steel grade, hardness (HRC), heat-treatment state, or proprietary alloy composition is not listed in the input data. Therefore, only general material intent can be stated: the WHP pipe construction is described as resistant to corrosion to support long service life and stable thermal performance.

Because hardness/heat-treatment details (e.g., quenched & tempered, nitrided, or pre-hardened) and wear-toughness trade-offs are not specified, engineers should confirm the exact material certificate or technical sheet for hardness (HRC), permissible operating conditions, and surface treatment.

• Confirm whether the pipe is an alloy steel, stainless alloy, or coated system before selecting for aggressive coolants.
• Verify any heat treatment or surface treatment that affects abrasion resistance and joining reliability.
• Compare only when multiple material grades are available with documented hardness and corrosion performance.

Select the outer diameter D based on available space and the required cooling-line flow path within the mold. Available OD values are 2, 3, 4, 6, and 8 mm, which helps tailor the routing to compact mold steel sections and narrow runner/cavity neighborhoods.

Match the length L to the physical run needed between the connection points in your cooling circuit. This product is offered in L = 35 to 225 mm, so choose the longest feasible length that still satisfies interference constraints and assembly access.

• Use D (2–8 mm) to meet cavity/core proximity requirements and minimize drilling offsets.
• Use L (35–225 mm) to bridge manifold spacing and local thermal demand zones.
• Where tight tolerances or press-fit joints are used, verify coupling/interface tolerances from the mating component data (tolerance/fit details are not provided here).

For best thermal stability, avoid sharp obstructions and ensure consistent routing along the highest heat-density areas.
