DAYTON XCN Coated Center Dowel Punches for Heavy Load - Metric

These heavy-load center dowel punches are used during precision injection mold and die build-up to establish reliable dowel hole location before final assembly. In practice, they help form and maintain stable centering under repeated clamp/return cycles, reducing the risk of progressive misalignment.

• Automotive connector and sensor housing tooling: the consistent shank diameter options (10, 13, 16, 20, 25 mm) and long body length (L = 80–130 mm) support accurate alignment for large, heavy components where wear and load can shift dowel features.
• High-cycle industrial housings: the XCN coating is selected to improve abrasion resistance for long production runs, helping the punch maintain dimensional stability when used repeatedly.
• Medical device housings (multi-part inserts): metric configuration supports repeatable assembly alignment, which is important when multiple cores/cavities must register consistently across maintenance intervals.

The heavy-load centering design plus abrasion-resistant XCN coating makes this variant suitable where alignment integrity and cycle durability are critical.

The provided product data specifies an XCN-coated center dowel punch intended for improved abrasion resistance during heavy-duty use. However, the input does not list the base steel grade, specific heat-treatment state (e.g., quenched & tempered, nitrided), or the achievable HRC hardness range.

• XCN coating role: increases wear and abrasion resistance at the working surfaces that experience sliding/impact during hole-forming and alignment.
• Trade-offs: with coatings, performance depends on coating thickness/adhesion versus underlying toughness; the underlying steel must still support the heavy-load centering function.

Because the steel grade and hardness are not specified in the supplied metadata, engineers should confirm the material certification for base hardness and heat treatment requirements before final selection.

Select dimensions by matching the punch geometry to the intended dowel feature in the mold components (plate/register locations, core/cavity alignment blocks, or heavy die setup plates).

• Shank diameter (D, mm): choose from D = 10, 13, 16, 20, or 25 to correspond to the target dowel bore size and guiding clearance requirements in your assembly.
• Overall length (L, mm): L is fixed in the range 80–130 mm; ensure the punch length provides the required reach through stacked tooling and still maintains full guidance during centering.
• Point length (L1, mm): select L1 = 13–19 or 19–25 to align with the depth of the hole-forming/spotting operation.
• Tip shape and fine geometry: select the tip shape (H, J, K, L, N, O, R, V, X, Y, Z) based on the dowel hole-forming profile, and match the P and W dimensions (P = 1.5–18 mm; W = 1.5–6 mm) and the R radius range (R = 0.2–5, 0.2–6.5, 0.2–8, 0.2–10, 0.2–12.5) to the desired edge radius.

If your drawing specifies fit/clearance, verify the punch’s D and tip-forming profile against the mold component tolerances to maintain repeatable registration.
