TCHH Tension Chain Holders for Holding Plates

TCHH tension chain holders are used in injection mold tooling where chain-driven motion controls the opening/closing of mold-related mechanisms or the movement of part-handling components. They are commonly integrated into material transfer, conveying, and indexing assemblies to keep a holding-plate-mounted chain in stable alignment during repetitive cycles.

In automated mold opening or transfer stations, the fixed holder design helps maintain consistent chain positioning, reducing alignment drift that can lead to uneven tension or premature wear on the drive components.

For conveyor and indexing systems feeding molded parts, selecting the correct chain size (40 or 50) ensures the chain seats correctly in the holder geometry. This product variant is suited because it is intended specifically for holding plates and chain stabilization in production equipment, where positional repeatability is critical.

• Use on holding-plate assemblies for stable chain control
• Select chain No. 40 or 50 to match alignment and fit
• Ideal for repetitive handling cycles requiring consistent tension

The provided product data for this series specifies the applicable chain number (40 or 50) but does not include the steel grade, heat-treatment state, or hardness (HRC). Therefore, no accurate material-property claims can be made from the available specifications.

When specifying tension-link components for mold-opening controllers, engineers typically select materials based on required wear resistance (for sliding contact) and toughness (to resist impact and vibration from indexing cycles). If your application involves higher loads or frequent reversals, confirm the supplier’s material grade and heat treatment (e.g., quenched & tempered or surface treatments such as nitriding) to balance hardness versus crack resistance.

• Material grade / HRC / heat treatment: not listed in provided specifications
• Confirm with the BOM against your duty cycle and contact conditions

Selection is primarily driven by the applicable chain number for this TCHH holder series. Choose the variant that matches the chain size used on your mold-opening controller or handling mechanism: chain No. 40 or chain No. 50.

To size correctly for your holding-plate assembly, verify two points before ordering: (1) the chain designation on the conveyor/indexing drivetrain, and (2) the plate layout that locates the holder mounting position relative to the chain path.

• Applicable chain No.: 40 or 50 (fixed options)
• Configurable dimensions: not provided in the current data; do not assume custom sizing beyond chain-number selection
• Tolerance/fit: ensure the chain seats and runs without misalignment; use the chain model’s published pitch/width to validate seating geometry

If your system uses a different chain designation, selecting the wrong chain number can cause incorrect engagement and unstable positioning during handling cycles.
