Center Dowel Punches for Heavy Load - Metric XCD Coating

This heavy-load center dowel punch is used to establish stable alignment during die and mold assembly where dowel holes must remain repeatable through many press cycles. In progressive die build-ups, the punch helps locate stacks and guide components so the die set returns to position with minimal play.

• Automotive and industrial connector tooling: Use it when aligning multiple sub-plates and locating bushings, helping reduce cumulative misalignment across repeated part runs.
• Medical device and electronics housings: In high-mix builds, it supports consistent cavity/core registration to improve part-to-part dimensional stability.
• Transfer and forming presses: The heavy-load design and controlled point geometry support secure seating in dowel holes under assembly handling and startup cycles.

The metric shank sizes (D = 10–25 mm) and the XCD coating variant are suited for long service intervals by enhancing surface durability at the locating interface.

The provided data specifies a center dowel punch with XCD coating, but does not list the base steel grade or heat-treatment state. Therefore, hardness (HRC) and microstructural targets (e.g., quench-and-temper, nitriding) are not stated in the available specification and should be confirmed with the supplier or incoming inspection documentation.

Practically, XCD coating is selected to improve surface durability and wear resistance at the contact area where the punch tip seats into dowel holes. The typical engineering trade-off is that higher wear resistance coatings can require proper surface prep and matching hole finish to maintain seating consistency over time.

• Coating-focused performance: better resistance to abrasion and fretting during repeated alignment operations.
• Base-material validation: confirm steel grade, target hardness, and any heat treatment before qualification for very abrasive or high-cycle environments.

Select dimensions by matching the dowel hole geometry and the alignment requirement of your die/mold assembly. The shank diameter D is available in 10, 13, 16, 20, 25 mm; choose the same diameter class as the dowel hole or the corresponding locating feature in the platens.

• Overall punch length (L): fixed at 80–130 mm range—choose based on platen thickness and how much insertion depth is required for stable seating.
• Point length (L1): available in 13–19 mm and 19–25 mm; select to ensure full engagement inside the dowel hole without bottoming.
• Tip geometry: tip shape options H, J, K, L, N, O, R, V, X, Y, Z to match your dowel hole profile and assembly tolerances.

Dimensions P (1.5–18 mm), W (1.5–6 mm), and R (0.2–5, 0.2–6.5, 0.2–8, 0.2–10, 0.2–12.5 mm) are variable and must align with your specified point/dowel interaction. Verify fit and seating by checking functional tolerance on the dowel holes and the punch tip radius to prevent excessive clearance or interference.
