Metric Close Space Ejector Punches XAN DayTAN™ Coating

Where it fits: Metric close-space ejector punches are used in injection mold tooling when ejector access is restricted and parts must release reliably from tight cavities.

Scenario 1 — Automotive connector housings: In compact multi-cavity tools, the close-space geometry supports stable ejection under constrained lateral clearance, helping maintain repeatable stroke behavior and consistent release of thin-wall components.

Scenario 2 — Electronics and housings in progressive/transfer tooling: When designs use metric progressive or transfer layouts, this punch style helps deliver ejection force where the tool requires clean access for slides, lifters, or stacked cavity structures.

Why this variant: The XAN DayTAN™ coating is selected to improve wear resistance and long-run release performance, which is especially valuable for higher-cycle production and molds with abrasive sprue, runner, or gate residue exposure.

• Close-space form for limited ejector clearance
• XAN DayTAN™ coating for improved wear/release stability
• Tip shape and shank/pocket compatibility to match restricted interfaces

These ejector punches are offered in M2 and PS material options, selected to balance wear resistance and toughness for different production demands.

• M2: High-speed steel commonly used for punch components where wear resistance is critical. In hardened condition (typically quench & temper), M2 provides strong cutting/punching wear performance, with toughness decreasing as hardness increases—so it suits stable, long-run ejection against abrasive contact.
• PS: A tool-steel option used for robust tooling applications; compared with M2, PS is often chosen when slightly lower wear aggressiveness and improved impact tolerance are preferred for certain load profiles.

Coating interaction: With XAN DayTAN™, the surface is engineered to reduce wear and help maintain consistent release, extending service intervals even when the ejector experiences repeated sliding and friction within the close-space pocket.

To select the correct close-space ejector punch, match the shank diameter D (5 ~ 32 mm) to the corresponding guide/bushing opening in your mold base. Use the provided L and L1 ranges to ensure the punch reaches the part while maintaining clearance to the cavity wall and pocket surfaces.

• D (mm): choose within 5 ~ 32 to fit your press-fit/guide interface.
• L (mm): select from 40 ~ 80, 40 ~ 100, 50 ~ 100, or 63 ~ 100 based on required ejection travel and tool stack height.
• L1 (point length, mm): choose 13 ~ 19, 19 ~ 25, or 25 ~ 30 to match the required contact/extraction length under close-space constraints.

Tip and contact geometry: Select the tip shape (H, J, K, L, N, O, R, V, X, Y, Z) and dimensions P (1.3 ~ 16 mm) and W (1.6 ~ 10 mm) to control part-contact area and prevent local stress concentration. R is fixed at 0.2 mm in the provided spec set; account for this radius when avoiding sharp interference. If your mold design uses tight tolerances, verify the fit around D with the mating bushing/guide bore to prevent binding during the close-space stroke.
