Backing Plates for True Position Ball Lock Retainer - Heavy

Heavy-duty backing plates like this one are used in injection mold tooling when precise retention of a locating mechanism is required, especially for systems built around true-position ball lock retainers. The plate provides a rigid interface between the retainer and the supporting plate stack, helping maintain stable clamp/locating performance while the mold cycles.

• Automotive and industrial connector molds: In multi-cavity molds where repeatable part location affects gate/fixture alignment, the heavy backing improves positional stability under repeated clamp load.
• Appliance and housings with tight cosmetic tolerances: When ball-lock components must resist micro-shifts during shutoff, this plate’s rigid assembly supports consistent location accuracy.
• General metric punch/insert tooling: The metric punch diameter compatibility of 10–40 mm helps engineers match common press configurations without re-engineering the interface.

Why this variant fits: Its heavy-duty design is intended to reduce movement of ball-lock retention features, supporting reliable, repeatable positioning across the listed punch diameter range.

The provided data specifies dimensional compatibility (D = 10–40 mm) and application intent (heavy-duty stabilization for true-position ball lock retainers), but it does not list the exact steel grade, hardness (HRC), or heat-treatment condition for this specific backing plate variant.

For ball-lock and backing plate components used in precision tooling, engineers typically select steels that balance wear resistance at the locating interface with toughness to withstand cyclic clamp forces and assembly stresses. Heat treatments are commonly specified as quenched and tempered for toughness or nitriding for improved surface wear resistance, depending on the interface loading.

If you share the material/heat-treatment datasheet for series 250000002245-124, we can map it to the relevant steel equivalence and quantify the HRC/trade-offs precisely.

To select the correct backing plate, match the applicable punch diameter (D) to your retainer/punch interface. This product supports D = 10 ~ 40 mm, so verify the punch diameter used in your true-position ball lock retainer system falls within that range.

• Step 1: Measure or confirm your punch diameter (the feature that the ball-lock retainer references). Use the nominal diameter specified by your press/mold tooling drawings.
• Step 2: Choose the backing plate variant whose D corresponds to your punch diameter. If your diameter is near the endpoints (10 mm or 40 mm), confirm sizing carefully to avoid misfit.
• Step 3: Ensure stack-up compatibility with the retainer and the surrounding plate hardware (bolt/pocket interface), since correct clamp geometry helps preserve true-position accuracy.

Tolerance & fit: The input data provides no explicit tolerance values for the plate-to-punch interface. In precision location applications, rely on your retainer/punch tolerance spec and confirm the assembled fit maintains stable contact without overconstraint.
