M2 Steel Ball Lock Ejector Punches Heavy Duty

This heavy-duty ball-lock ejector punch is used in injection mold tooling where stable part ejection is critical under repeated cycles. The ball-lock tip design helps support accurate retention and positioning during stroke, reducing the risk of misalignment-related ejection issues.

• Automotive interior/exterior components: Suitable for die and punch-and-die stations that produce deep or complex shapes, where repeated ejection demands strong wear resistance from the M2 steel body and consistent tip geometry.
• Appliance and industrial housing inserts: Works well for molds that require dependable ejection of metal or reinforced polymer inserts; the ball-lock head improves functional reliability when tool access and ejection travel are constrained.
• High-cycle metric die operations: The XNM coating variant supports improved surface performance during long production runs, helping maintain ejection accuracy across cycles.

Select the appropriate shank diameter and point length to match cavity/core requirements and ensure the ejector’s stroke remains stable.

The standard variant uses M2 high-speed steel, selected for its balance of hardness and wear resistance in punching and ejection duty. For aggressive die applications, a surface-enhancing XNM coating is specified in the product description to improve performance under repeated contact and sliding.

• M2 (tool steel): Typically supplied in a hardened condition for service; the key trade-off is that higher hardness increases wear resistance but can reduce toughness if overspecified for impact loads.
• Alternative material (PS4): Offered as a selectable option in this product series; choose when you need different performance characteristics versus M2 for your die environment.

Manufacturing is generally based on precise machining and finishing of the ball-lock tip geometry, followed by coating application for the XNM option to support long-cycle surface durability.

To select the correct ejector punch dimensions, start by matching the shank diameter (D) to the leader/bushing and guidance features in your tooling. Available D values are 10, 13, 16, 20, 25, and 32 mm; choose the size that provides proper guidance and prevents lateral movement during ejection.

• Point length (L1): Select from 10–19 mm or 13–25 mm depending on your cavity depth and how much the tip must enter to release the part.
• Total length (L): Match the installed stack-up. Options include 63–100 mm, 63–125 mm, or 71–125 mm depending on your assembly height.
• Ball-lock geometry: Tip shape can be H, J, K, L, N, O, R, V, X, Y, or Z; verify this against your part release profile and contact area needs.

Because this is a precision ejection component, confirm fit with your ejector bore clearance and any standard tolerance you use for ejector tooling; the W, P, and R parameters define the point/edge geometry and should be selected to avoid interference with cavity surfaces.
