Metric Backing Plates for True Position Ball Lock Retainer -

These metric backing plates are used in injection molding and tooling builds where true-position ball lock retainers must reliably stabilize punch-related components under repeated press loading.

• Automotive and appliance connector molding tooling: Pair the plate with a ball-lock retainer to maintain consistent punch location during high-cycle operations, helping reduce drift-related defects around critical features.
• Industrial enclosure and bracket molds: Use the heavy-duty backing plate to rigidly lock the ball-lock system, improving repeatable part positioning when multiple cavities or gang features rely on tight alignment.
• Medical device housing tooling: When dimensional repeatability is essential, the backing plate’s role in supporting rigid assembly helps sustain stable clamp performance that supports downstream inspection tolerances.

The variant is suited because its punch-diameter compatibility (10–40 mm) aligns with common tooling configurations and provides a robust base for the ball-lock retention geometry.

The provided product data does not specify a steel grade, hardness (HRC), heat-treatment condition, or surface treatment for this backing plate.

• Material properties: Select backing plate steel based on the required rigidity and wear resistance for your press/load regime; typical choices for tooling backing components balance toughness to resist deformation while maintaining adequate stiffness.
• Heat treatment: Common manufacturing routes for mold components include controlled machining of the plate followed by quench-and-temper or similar treatments to achieve stable dimensional performance.
• Trade-offs: Higher hardness generally improves wear resistance, but can reduce toughness if not tempered correctly—especially relevant under shock loads.

If you need a grade comparison (e.g., pre-hardened vs. quenched & tempered, or nitrided options), share your operating load and cycle expectations so the appropriate spec can be confirmed against available material offerings.

Use this backing plate by matching its applicable punch diameter (D) to the punch size used with your true-position ball lock retainer assembly.

• Punch diameter range: Confirm your punch diameter is within 10–40 mm to ensure proper compatibility and stable locking.
• Core/cavity alignment logic: In tooling stacks, the backing plate acts as a rigid stabilization layer for the ball-lock system; selecting the correct D supports consistent positioning that translates to more reliable feature alignment in the final molded part.
• Tolerance and fit considerations: Because dimensional fit depends on both the punch diameter and the mating ball-lock hardware, verify that your retainer and punch dimensions fall within their specified tolerances to avoid preload loss or binding.

All sizing for this SKU is driven by the fixed D (10–40 mm) specification; other dimensions are not provided in the available data, so confirm the remaining interfaces from the retainer and punch datasheets.
