Metric Center Dowel Punches for Heavy Load TiCN Coated

Center positioning punches like this are used in injection mold tooling where repeatable alignment between mold components is critical—especially during cavity/core assembly and during press runs that see frequent load cycling.

• Automotive and appliance housings: the single-stepped shank and locating dowel hole mounting style help maintain stable center fixing, reducing the risk of center drift when the mold is closed under heavy clamp loads.
• High-cavitation steel die/fixture systems: round/rectangle/oblong/radius tip options support contacting different feature geometries, while the TiCN (XCN) coated shank improves resistance to abrasive wear at guiding and contact surfaces.
• Multi-part assembly fixtures: the variant’s metric shank diameter range (D = 10–45 mm) supports selecting a punch size that matches core/die locating features for consistent press assembly.

Overall, the TiCN (XCN) wear-resistant shank and heavy-load center locating design make it suitable for long-life alignment in demanding mold and die environments.

This series is available in two steel options: SKH51 equivalent (M2) and SKH40 equivalent (powdered high-speed steel). Both are high-speed steel grades chosen for cutting/contact durability and resistance to wear under repeated tool loading.

• SKH51 (M2 equivalent): typically used where a balance of hardness and wear resistance is needed for longer contact life.
• SKH40 (powdered HSS equivalent): the powdered route generally supports consistent microstructure and wear behavior, which can be advantageous when uniform performance across many parts is required.

In practice, these grades are commonly supplied and/or heat-treated into a hardened state (for example, quenched and tempered for HSS use), then finished to final dimensions. Hardness-to-toughness trade-offs apply: higher hardness improves abrasion resistance, while toughness must remain sufficient to avoid chipping at the tip during heavy centering contact.

Select the center dowel punch dimensions by matching the punch tip and shank features to the locating geometry in your mold base, then verify fit for the assembly process.

• Shank diameter (D = 10–45 mm): choose the nearest D that matches your locating sleeve/dowel hole clearance. The design is intended for a heavy-load press assembly with a stable fit around the locating dowel hole style.
• Tip size (P = 2.5–35 mm and tip shape selection): pick the tip dimension and profile (round/rectangle/oblong/double flatted round/radius rectangle) so the punch engages the intended center feature without overstressing edges.
• Lengths: use L = 50–150 mm (multiple L range options apply) and full-length alteration LC ranges (e.g., 37–149.9 mm, 42–149.9 mm, 42–129.9 mm, or 130.09–149.99 mm) to match your mold thickness and stack-up.

Maintain the specified tolerances through partner component machining; where fit is critical, confirm clearance for the locating dowel hole mounting before final assembly.
