Product Guide

🏭Application Scenarios+

This heavy-duty ball-lock ejector punch is used in injection mold tooling where the ejector needs secure retention and consistent stroke-to-stroke performance. Its ball-lock interface supports positive positioning in the ejector system, helping prevent shift during repeated cycling.

  • Automotive connector and housing molds: suited for high-cycle ejection of parts with draft-sensitive geometry, where stable fit and reliable retention reduce the risk of sticking or misalignment. The XAN DayTAN™ coating helps maintain wear performance under abrasive contact.
  • Industrial appliance and appliance-control enclosures: ideal for die and mold setups that require repeatable ejection from thin ribs or bosses. The heavy-duty inch format supports robust toolmaking and maintains performance across demanding production runs.
  • Medical device packaging components (non-sterile housings): used where controlled ejection is needed to protect surface finish. The XAN DayTAN™ coating supports lower friction at the punch/plate interface.
🔧Material & Process Details+

The provided specification set does not state a specific steel grade or hardness value. For accurate materials selection and qualification, confirm the base steel grade and heat-treatment condition for series code 250300512560 before final process sign-off.

  • Coating function: the XAN DayTAN™ coating is specified to support stable wear performance by reducing friction at the ejector/punch contact surfaces. This improves wear resistance in long-cycle applications.
  • Heat treatment: no quenched & tempered, nitriding, or other heat-treatment parameters are included in the input data; therefore, hardness (HRC) and toughness trade-offs cannot be stated from the given specifications.
  • Manufacturing process (tool-relevant): ball-lock punches are typically precision-ground for seating surfaces to maintain retention and alignment; the specified tip shape options (H, J, K, L, N, O, R, V, X, Y, Z) indicate a geometry-dependent tip finishing strategy for consistent ejection behavior.
📐Sizing & Selection Guide+

Use the provided dimensional codes to match the ejector punch to the mold cavity/core ejection layout while maintaining proper retention in the tool.

  • Shank (D) selection: choose the shank diameter from the available range 37 ~ 125 in to fit the mating bore and ball-lock pocket in your ejector plate or support component.
  • Length (L) selection: select from 250 ~ 450 or 275 ~ 450 (coded inch). Match this to the required protrusion beyond the parting plane and the full stroke travel, including safe clearance at the back end.
  • Tip geometry: pick the required tip shape (H, J, K, L, N, O, R, V, X, Y, Z) to control contact area and ejection force distribution on the part surface.
  • Interface dimensions: verify P (0.376 ~ 1.251 in) and W (0.062 ~ 1.083 in) against the punch/stop and seating features of your design, including radii/relief indicated by R (0.007 ~ 1 in range options).

Follow the manufacturer’s drawing for tolerance/fit details; the input data provides ranges but not allowable tolerance values.

Frequently Asked Questions

How does the ball-lock interface affect ejector retention and alignment during repeated cycles?+
The series specifies a ball-lock style for positive positioning and secure retention in mold assemblies. In practice, this helps maintain punch alignment during repeated ejection strokes. For final verification, confirm the mating ejector plate/support pocket geometry corresponding to the selected shank diameter range 37 ~ 125 in.
Which tip shape options (H/J/K/L/N/O/R/V/X/Y/Z) are used to tune ejection contact for different part geometries?+
This variant supports multiple tip shapes: H, J, K, L, N, O, R, V, X, Y, Z. Select the tip shape based on the required contact area and how the punch engages bosses, ribs, or film-like surfaces. After choosing the tip, validate the interface dimensions P (0.376 ~ 1.251 in), W (0.062 ~ 1.083 in), and the available R range in the detailed drawing.
What coating does this ejector punch use, and how does it relate to wear or friction in the ejector system?+
The product description specifies XAN DayTAN™ coating for reliable ejection in toolmaking. Its stated role is to support stable wear performance and reduce friction at the contact interface. This is particularly relevant for long production cycles where the punch/plate area experiences recurring rubbing or abrasion.
How should I choose length L for ensuring correct protrusion and clearance?+
The available lengths are specified as 250 ~ 450 or 275 ~ 450 (coded inch). Choose the value that provides the required working protrusion beyond the parting line while leaving clearance for the back travel and any ejector return features. Also verify the shank diameter D (37 ~ 125 in) matches the tool’s mating bores.
Are material grade, heat treatment, and HRC hardness provided for series 250300512560?+
The supplied data includes the XAN DayTAN™ coating and geometric specifications, but it does not list the steel grade, heat-treatment state, or HRC hardness. To evaluate toughness vs. wear trade-offs, request the steel/heat-treatment details from the product drawing for series code 250300512560.
