Cooling Circuit Plug Installation Tool for Sealing Cooling Channels

This installation tool is used in injection mold and die-casting die maintenance workflows where cooling channel plugs must be seated reliably to prevent coolant leakage. In large die-casting tools, it helps seal cooling circuits so coolant level stability is maintained, supporting consistent thermal conditions across the mold life.

Common scenarios include: die-casting cooling loop service, where plugs are installed in existing cooling galleries to restore flow integrity; and production mold refurbishment, where older sealing performance needs to be improved without extensive rework. Because the tool is offered in multiple variants (D6, D8 & 10, D12) and as set products, it matches different plug installation diameters and installation types found in tooling.

• Sealing installation types: compatible with plug installation styles such as JWPK and JWPKS.
• Operational benefit: reduces leak risk and supports protected coolant levels, improving system efficiency.

The provided specification data for this product lists tool configuration options (D6, D8 & 10, D12, sets, and special wrench/instruction manual) but does not state a steel grade or heat treatment condition. As a result, hardness (HRC), wear resistance, and toughness trade-offs cannot be confirmed from the input information.

When selecting a variant for mold shop use, the critical differentiator is typically fit/compatibility for the plug installation diameter and type (e.g., JWPK/JWPKS), rather than material choice. For components that interface repeatedly with plugs during installation, ensure the tool material matches your plant standards for shop durability and surface finish requirements.

• Not specified: steel grade equivalency (e.g., SKD61/H13) and heat treatment state (nitrided, quenched & tempered, etc.).
• Confirmed: variant-based sizing approach (D6, D8 & 10, D12) and compatibility with common plug styles.

To select the correct tool, choose the variant that matches the plug installation diameter required by your cooling channel system. Your available options are D6 tool, D8 and 10 tool, D12 tool, plus set products and items such as special wrench・instruction manual.

In practice, start from your mold’s cooling design or the installed plug specification, then map it to the tool size:

• Use D6 tool when the cooling circuit plug installation is specified for the D6 class.
• Use D8 and 10 tool when the required installation corresponds to D8 or D10.
• Use D12 tool for D12-class installations.

Fit considerations: the tool must properly engage the plug installation interface to achieve secure seating and effective sealing. If your project uses mixed plug types (e.g., JWPK / JWPKS), verify compatibility first, then select the tool variant based on the plug diameter requirement. Tolerances are not provided in the input data, so rely on plug specification and verified engagement rather than assumed clearance.
