PBC Type Puller Bolt Collars Covers for Three-Plate Mold

In three-plate injection mold tooling, these puller bolt collar covers help keep the puller bolts correctly guided during assembly and repeated cycling. They are typically installed on the puller-bolt-related interface to protect the bolt collar area while ensuring concentric alignment as the mold opens and closes.

• Three-plate molds for automotive connector housings: Use the PBC cover style to improve assembly repeatability and maintain stable clamp/opening behavior under frequent production cycles.
• Industrial electronics enclosures: The cover format helps align the puller bolt system when servicing the mold, reducing misalignment risk during reinstallation.
• General-purpose multi-cavity production runs: The guided, shielded design supports consistent operation by protecting and aligning puller bolt components during routine maintenance.

This variant is suited because the PBC cover design focuses on positioning and protection of the puller bolt collar region, which directly supports stable performance in three-plate mold systems.

The provided specifications list dimensional inner diameter d (6, 8, 10, 12, 16 mm), but no steel grade, hardness (HRC), or heat-treatment state is specified in the input data. Therefore, material property claims (such as whether the part is nitrided, quenched & tempered, or its wear/impact hardness trade-off) cannot be stated accurately for this specific item variant.

When selecting a collar cover material for puller-bolt environments, mold builders typically balance wear resistance against toughness to prevent collar-area deformation and maintain stable guidance through repeated cycles. If you require a specific steel grade and HRC target for compatibility with your existing puller bolt set, share the puller bolt material/heat-treatment reference so we can match the collar cover accordingly.

• Data note: Material, standard, and tolerances are not supplied here—confirm with Axiom Molds/MISUMI technical drawings for your exact size.

Selection is primarily driven by the cover’s inner diameter d. Choose the size that matches the puller bolt collar/bore interface in your three-plate mold puller system so the cover can properly guide alignment without binding.

• Available d values (mm): 6, 8, 10, 12, 16
• Match strategy: Measure the relevant interface inner feature (e.g., bolt/collar region bore or collar-related diameter) in the mold assembly and select the cover with the same nominal d.
• Fit considerations: If your puller system uses a close-fit guidance area, verify the tolerance class on the mating component so the cover can slide/seat correctly during assembly and maintenance.

Dimensions shown for this product are limited to d in the provided data; if other dimensions (outer diameter, length, or mounting features) are required for cavity/core clearances, consult the product’s drawing for the specific d size you select.
