Ball Lock Ejector Punches - Point Larger than Shank, Regular

Ball lock ejector punches like this are used in injection and press tooling where consistent ejection depends on stable punch-to-workpiece alignment. The geometry with a point larger than shank helps seat the punch securely and resist lateral shift during stroke, which is valuable when parts require positive release and repeatable positioning.

Common scenarios include:

• Automotive connector and housing molds: supports heavy-duty ejection in transfer or press-like operations where cycle loads can accelerate wear; the XVP coating helps maintain performance over repeated cycles.
• Appliance and housings: stable blank support during forming reduces risk of galling and misalignment, improving consistency for long production runs.
• Metal-forming die tooling: the optimized point/tip selection supports reliable action across a range of die tip shapes (H, J, K, L, N, O, R, V, X, Y, Z).

Overall, this variant is suited for applications demanding dependable blank support under heavy-duty forming loads.

The provided product data specifies the XVP coating and the ejector-punch geometry, but it does not list a steel grade, hardness (HRC), or a specific heat treatment condition (e.g., quenched & tempered, nitrided). Therefore, material property claims are limited to the documented coating benefit and the functional intent of the design.

• XVP coating: designed to improve wear resistance for repeated forming cycles, supporting stable ejection performance and longer service intervals.
• Wear vs. toughness trade-off: in coated punch components, coating wear resistance typically helps maintain tip geometry; however, base-metal toughness and heat treatment still control chipping resistance under shock loads.

Select the correct ball lock ejector punch dimensions by matching the shank diameter (D), point length (L1), and the point shape to the cavity/core features and ejection stroke requirements.

• D (shank dia.) (mm): choose from 13, 16, 20, 25, 32, 40 based on the guide pocket and ball-lock interface clearances.
• L1 (point length) (mm): fixed at 19 ～ 30 to control how deep the point engages during ejection.
• L (overall length) (mm): fixed at 80 ～ 100 to ensure reach through the tool stack without bottoming.
• P and W dimensions: pick the available ranges that correspond to the local geometry constraints (P: 13.1 ～ 32, 16.1 ～ 38, 20.1 ～ 40, 25.1 ～ 44, 32.1 ～ 50, 40.1 ～ 56; W: 1.57 ～ 34.73).
• R (radius) (mm): select the radius available for your tip/profile (0.2 ～ 16, 0.2 ～ 19, 0.2 ～ 20, 0.2 ～ 22, 0.2 ～ 25, 0.2 ～ 28).

Because exact tolerances and fit clearances are not specified in the input data, verify your tool drawing’s ball-lock seating and guide clearance requirements against the chosen D and geometry, especially under heavy-duty forming loads.
