Double Flange Tension Link Retainers

This double-flange tension link retainer is used in injection mold tooling wherever a tension link system must stay in a repeatable linkage position across cycles. In mold-opening controller assemblies, it helps stabilize the retention point that holds the special tension link hardware, improving positional consistency during opening and closing.

• Automotive-style connector and multi-cavity molds: Use the retainer (or retainer + bolt) to secure tension link setups that guide controlled movement of moving components, reducing drift in linkage positioning.
• Industrial fixture housings and linkage mechanisms: The double-flange contact area provides stable seating for special bolt diameters (10 / 13 / 16 / 20 mm), supporting reliable retention under frequent actuation.
• Quick-assembly mold builds: Choose the “Retainer only” or “Retainer + bolt” sales form to match your installation workflow and minimize time during maintenance.

The provided product data does not specify a steel grade, hardness (HRC), or heat treatment state for this double flange tension link retainer. As a result, material properties (e.g., wear resistance vs. toughness trade-offs), nitriding/quenching/tempering details, and dimensional stability expectations cannot be stated reliably from the current inputs.

• What to verify for material performance: Request the exact steel grade and heat treatment condition used for the retainer body.
• Why it matters: Tension link components experience repeated mechanical loading; the correct hardness and surface treatment influence wear at contact faces and resistance to deformation.
• Availability comparison: If multiple material grades exist for different bolt diameters (10 / 13 / 16 / 20 mm) or sales forms, compare them based on hardness and heat treatment rather than only geometry.

Select the retainer based on the tension link special bolt diameter D and the specified dimension L. The available D options are 10, 13, 16, and 20 mm, and L options are 11 and 18 mm, which must match the geometry of your tension link assembly.

• Match bolt diameter: Use the retainer variant intended for your tension link bolt diameter (10 / 13 / 16 / 20 mm) to ensure correct seating and retention stability.
• Match length (L): Choose L = 11 mm or L = 18 mm to fit the available space and engagement length in the mold-opening controller assembly.
• Sales form compatibility: For faster installation, select Retainer + Bolt; if bolts are already specified for your design, select Retainer only.
• Tolerance/fit: Confirm your design’s allowable clearance and the contact face requirements with the supplier drawings, since tolerance values are not provided in the current specification.
