TiCN Coated Short Shoulder Punches

These TiCN-coated short shoulder punches are used in injection and forming mold tooling where high punch load, abrasive wear, and stable guidance are critical. The single-stepped shank helps maintain seating consistency and controlled punch alignment, improving repeatability in production.

Scenario 1: Automotive connector and terminal modules—use the TiCN (XCN) surface option to help resist wear in cycles involving abrasive inserts or hard wire/blank materials, while hardened steel options support dimensional stability over long runs.

Scenario 2: Appliance and electronics housings—the compact shoulder geometry and efficient tip machining support reliable part release and consistent forming of small features, especially where multiple cavities demand uniform punch height and guidance.

Scenario 3: Medical device components—when tight feature definition matters, select hardened steel (SKD11/D2 or SKH51/M2 equivalents) for toughness/rigidity balance, and retain the TiCN coating where surface durability against repeated contact is required.

• TiCN (XCN) coating supports wear reduction for abrasive cycles
• Hardened steel bodies (SKD11/D2 or SKH51/M2 equivalents) provide stability under load

This punch series is offered in hardened steel options with a TiCN (XCN) surface treatment choice. Recommended equivalents include SKD11 (D2 equivalent) for strong wear resistance and stability, and SKH51 (M2 equivalent) for high-performance cutting-punch tooling characteristics. A third option, SKH40 (powdered HSS equivalent), is available where a different performance balance is required for wear and toughness.

TiCN (XCN) coating option is selected to reduce surface wear during abrasive punch cycles and to maintain tip integrity for consistent forming.

• Hardness/heat treatment: The body materials are specified as hardened steel options; heat-treatment state and resulting HRC are dependent on the selected steel grade option.
• Trade-offs: Generally, D2-class steels emphasize wear resistance; M2/HSS-class options can offer improved toughness versus highly wear-focused grades, while the coating shifts surface wear behavior toward longer service life.

Choose based on expected load, abrasive conditions, and required tip life.

Select dimensions by matching the punch shank and tip geometry to the die cavity/core feature, while respecting the provided diameter and tolerance constraints. Start with the D shank diameter: available sizes are 3, 4, 5, 6, 8, 10 mm. Use the m5 tolerance with the specified allowance +0.005/0 for shank diameter to ensure proper fit in the punch plate and guidance bushing.

• Tip shape options: Round, Rectangle, Oblong, Double Flatted Round, Radius Rectangle—pick the tip that matches your die recess geometry.
• Tip dimension P: ranges from 1 ~ 7 mm depending on your selected configuration.
• Head/tip length options: L is provided in ranges such as 30–40, 25–40, 30, 25–30 mm. For overall length alteration, LC is listed in ranges including 17–39.9 mm and other narrower configurations (e.g., 35.09–39.99 mm).
• Head thickness tolerance change: LMT is fixed in 17–39.9 mm, while LCT matches the 17–39.9 mm range.

Finally, confirm tip corner and size features—R = 0.15 mm and PC = 0.3 ~ 3.5—to avoid mismatch with die radii and feature clearances.
