Product Guide
Application Scenarios+
This light-duty true-position ball lock retainer is used in precision injection-mold tooling when repeatable punch alignment is needed for consistent cavity/core features. It is commonly integrated into punch-and-die assemblies that perform locating for inch-sized punches, helping maintain stable seating throughout normal press cycles.
- Automotive/consumer component molds: Use the 25–100 in. applicable punch diameter range to lock punch location for repetitive features such as connector bosses or decorative reliefs, where alignment repeatability affects part fit and appearance.
- Electronics housing and brackets: The ball-lock locking action supports secure retention during cycling, reducing the risk of drift that can mis-register features across molding runs.
- Short-run or frequent setup indexing: The light-duty configuration is suited to efficient tooling indexing and handling, lowering changeover effort for inch tooling.
Material & Process Details+
The provided product data does not specify a steel grade, heat treatment, or hardness (HRC) for this DAYTON light-duty true-position ball lock retainer. As a result, material-property statements beyond the given specifications cannot be verified from the current input.
When selecting retainers for punch locating, engineers typically match the retainer’s wear resistance and toughness to the punch load profile and the expected press cycle count. If you need confirmation for a specific application, request the material/heat-treatment certificate or datasheet for the exact part number (series code: 250301834636).
- Request for verification: Ask for steel grade, quench & temper or nitriding state, and target hardness (HRC).
- Compatibility check: Ensure the retainer’s finish and dimensional control are consistent with your punch’s true-position requirements.
Sizing & Selection Guide+
Select the retainer based on the applicable punch diameter (D). For this light-duty inch series, the specified range is 25 ~ 100 in.
- Step 1—Match diameter: Choose the retainer whose D rating covers your punch diameter without forcing oversize contact.
- Step 2—Align cavity/core needs: True-position seating helps maintain repeatable punch location, so use it where small location changes could affect feature registration in the molded part.
- Step 3—Check fit and tolerance: The input data does not provide retainer-to-punch tolerance or fit classes. Verify with the manufacturer drawings for your punch locating interface to ensure proper seating and secure lock-up during press cycles.
Dimensions are configurable by punch diameter within the stated D range, while other critical fit details are typically fixed to the part design; confirm those from the technical drawing for your selected punch size.
Frequently Asked Questions
What punch diameter range is supported by this light-duty true-position ball lock retainer?+
The specified applicable punch diameter (D) range is 25 ~ 100 in. Select a retainer where your inch punch diameter falls within this range to ensure correct seating for repeatable punch location.
How does the ball-lock mechanism help maintain repeatable punch location during molding cycles?+
This design uses a ball-lock locking action to provide secure retention of the punch during production. Combined with true-position seating, it helps maintain repeatable punch location under normal press cycles, reducing drift that can cause feature mis-registration.
Is this retainer considered light-duty, and when is that configuration most appropriate?+
Yes, the configuration is light-duty for inch tooling. It is intended for efficient setups and repeatable tooling indexing, where frequent handling and alignment stability are important but extreme heavy-load retention requirements may not apply.
Does it follow Dayton/Lamina part-number formatting for compatibility in tooling procurement?+
The product is described as using the Dayton Lamina part-number format and supporting secure lock-up. This helps streamline procurement and compatibility within systems that reference Dayton/Lamina standard part-number conventions.
What material grade and hardness should I expect for the 250301834636 retainer?+
The current input data does not list the steel grade, heat treatment state, or hardness (HRC) for series code 250301834636. For engineering-critical applications, request the official material/heat-treatment documentation and hardness targets to confirm wear resistance and toughness suitability.
