Ball Lock Ejector Punches Heavy Duty, Inch XCD Coating

Ball-lock ejector punches are used in injection and compression mold tooling where high-cycle part removal demands consistent punch retention and stable ejection forces. The XCD coating variant helps reduce surface wear and abrasion, supporting longer service intervals in demanding production environments.

• Medical device housings and precision shells: Select inch-coded point lengths (e.g., 250–600 coded inches depending on group) to align with cavity/core stack-up, helping maintain repeatable ejection geometry over continuous runs.
• Automotive interior/exterior components: Heavy-duty ball-lock engagement supports reliable punch-to-plate contact under higher load, while the XCD coating improves wear resistance against abrasive molded skins and sprue remainders.
• Electronics enclosures and connector housings: Choose tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) matched to runner gates and ejector layout for repeatable forming and clean part release.

This variant is suited for engineers targeting robust ejection performance with reduced downtime.

This heavy-duty ball-lock ejector punch is available in M2 or PS4 material options, supporting selection based on tool wear needs and toughness requirements.

• M2: A high-speed steel grade commonly selected for excellent wear resistance under intermittent impact and abrasion. Typical heat treatment is quench and temper to achieve a balanced hardness/toughness condition; final hardness is often specified in the high-HRC range for durability in repeated cycling.
• PS4: A tool steel option suited for stable performance where a cost-effective wear-toughness balance is needed; heat treatment is commonly provided in a hardened condition appropriate for ejector service.

Hardness trade-off: Higher hardness generally improves abrasion resistance but can reduce toughness under shock. Select the material and heat treatment state to balance HRC level against expected ejection loads, guide wear, and any side-load conditions.

Use the coded inch specifications to match the ejector system geometry to your mold cavity/core requirements. Confirm the shank diameter D first: available in the range 37–125 in (as provided), since this governs fit, alignment, and ball-lock retention engagement in the tool set.

• Select point tip shape: Choose from H, J, K, L, N, O, R, V, X, Y, Z based on part release contact area and ejection footprint requirements.
• Match length coding: Standard point length & L are offered in coded inch ranges such as 250–500, 250–600, 275–600, and 300–600 depending on the configuration/group.
• Verify P, W, and R dimensions: Ensure P is within 0.062–1 in, W within 0.062–0.5 in, and R within 0.007 in range to match the ejector contact profile.

Because these are cataloged with coded inch length ranges, treat lengths as configuration-controlled; verify stack-up clearances to maintain proper tool fit and avoid binding during cycling.
