Steel TiCN Coated Ball Lock Ejector Punches - Heavy Load, Wrench Flat

Ball lock ejector tooling relies on consistent punch alignment and controlled ejection force. This heavy-load, TiCN-coated variant with a wrench flat style is commonly used in injection mold assemblies where repeatable movement under high duty cycles is required.

• Automotive connector and housing molds: Use the wrench flat geometry to improve handling during tryout and maintenance, supporting stable positioning of the ejector system while the TiCN coating helps resist wear at the punch tip.
• Consumer electronics casings: In molds with tight packaging and frequent actuator cycles, the heavy-load construction supports long-run ejection while maintaining edge strength for reliable stroke-to-stroke behavior.
• Progressive dies and multi-cavity tools: The ball-lock ejector punch format and hardened core are suited for assemblies that demand consistent alignment and repeatable ejection in high-cycle production.

This punch is manufactured from hardened SKH51-equivalent (M2) high-speed steel, selected for its balance of edge retention, wear resistance, and toughness under ejector loading. In service, the cutting edge is the critical wear location; maintaining hardness helps preserve ejection stability and dimensional consistency.

• TiCN (XCN) coating: Provides improved surface wear resistance against adhesive/abrasive wear mechanisms common at the tip.
• Heat treatment state: Hardened for load-bearing performance typical of M2-class steel; exact hardness value is not specified in the provided data.
• Trade-offs: HSS cores offer better wear/edge strength, while coating supports a longer effective life; extreme toughness limits are not stated, so system design should still account for load and guidance quality.

Select dimensions by matching the punch shank and tip geometry to the ejector plate interface and the mating ball-lock pocket/guide constraints in the mold. This series supports shank diameters D = 10, 13, 16, 20, 25 mm and tip length options B = L or S with L (L Dimension) ranges of 80–100 mm or 71–100 mm.

• Tip geometry match: Choose the Tip Shape (Round, Rectangle, Oblong, Double Flatted Round, Radius Rectangle) and set P = 3–18 mm plus the corresponding W (3–6 mm) and radii R = 0.15–4.94 to 0.15–12.44 mm based on contact area needs.
• Length compatibility: Confirm the full-length alteration LC = 54–99.9 mm (multiple options) fits the ejector stroke stack-up and shutheight variation.
• Fit/tolerance: For proper ball-lock seating and guidance, maintain the designed clearance between punch diameter D and the mating components; coating thickness can slightly affect effective surface tolerance, so rely on your drawing’s fit class and gauge requirements.
