TCHE Tension Chains for Holding Plates

This TCHE tension chain is used in injection mold tooling to keep holding plates firmly clamped during mold opening/closing cycles. The chain linkage maintains stable tension so the clamping interface resists loosening caused by repeated dynamic loading.

• Mold opening controller assemblies: Install the chain as part of the tension-link components that balance clamping force and help maintain consistent plate positioning across cycles.
• Holding-plate tensioning for industrial automation: Use chain size 40 or 50 to match the required mechanical stiffness and drive system envelope for the clamp linkage.
• Longer tension spans on multi-plate setups: Select an odd-number link count (e.g., 241, 5–239, 193, 5–191) to tune total tension length and obtain the correct take-up/adjustment behavior.

Because this variant is specified by selectable chain size and odd-number link counts, it is suited for applications where precise tension-length matching is necessary for reliable plate clamping.

The provided product data focuses on chain linkage selection (chain No. and odd-number link counts) rather than a specific steel grade. As a result, the exact material composition, heat treatment state, and hardness (HRC) cannot be confirmed from the available specifications.

In general, tension-link components for mold-opening controllers are manufactured from hardened steels or through heat-treated alloy steels to resist wear at articulation points and maintain strength under cyclic load. Typical manufacturing routes include precision forming of chain links, heat treatment (commonly quench & tempering), and finishing to achieve stable pitch and fit between links.

• Wear vs. toughness trade-off: Higher hardness improves wear resistance at the pin/bushing interfaces, while excessive hardness can reduce impact toughness—selection should match your cycle rate and shock loading.
• Heat treatment: Look for documentation confirming quenched & tempered or equivalent hardened condition when you require measured HRC and fatigue performance.

Select the correct TCHE tension chain by matching both the Applicable chain No. (mm) and the odd-number link count to your mold’s holding-plate clamping length and travel/take-up requirements.

• Choose chain size: Pick 40 or 50 (Applicable chain No. in mm) to fit the mechanical design envelope and the intended stiffness of the clamping linkage.
• Choose link count (odd number): Use the listed options—241, 193, or ranges of 5–239 and 5–191—to tune total chain length. The odd-number designation helps align tension geometry with the design’s required tension-length profile.
• Match cavity/core requirements: Determine the required effective tension span between holding-plate attachment points, then select the chain length using the link count as your primary tuning parameter.

If your design includes fine adjustment, verify how your system accounts for take-up; while tolerance values are not provided here, ensure the selected pitch/length maintains proper clamping force without binding through full mold stroke.
