Center Dowel Punches for Heavy Load - Metric (XCDP Coating)

Center dowel punches like this variant are used during injection mold and die builds to lock alignment between cavities, slides, and supporting plates. In heavy-duty tooling, they help establish repeatable “start positions” for dowel seating so parts remain concentric through repeated press cycles.

• Automotive connector and housing molds: Use the heavy-load metric geometry with XCDP coating to maintain stable tool alignment during high-frequency, tight-tolerance insert and connector core alignment.
• Medical device packaging or small-part molds: When centering consistency is critical for repeat cavity spacing, the point-length options (L1 ranges) support correct engagement depth without disturbing established dowel fit.
• Industrial housings and appliance components: For housings requiring durable registration under abrasive conditions, the XCDP surface treatment reduces wear at punch–dowel contact points, supporting longer alignment life.

This series specifies an XCDP coating on a center dowel punch surface to improve wear behavior during punch–dowel engagement in heavy-load tooling. While the provided data does not list the base steel grade or a specific hardness value (HRC), the intent of XCDP is to enhance resistance to surface wear and maintain centering stability over repeated operations.

• Wear resistance vs. toughness: Coated punch surfaces generally prioritize surface hardness and durability, which can improve life at the contact zone while relying on the underlying tool steel for bulk toughness.
• Manufacturing approach: Center dowel punch geometries are formed to metric shank and point dimensions, followed by surface treatment (XCDP) for reduced galling and controlled wear during dowel seating.

If you need exact HRC and heat-treatment state for your build standard, share the intended application load profile; we can align material selection and processing to that requirement.

Select dimensions by matching the punch tip engagement and shank fit to your core/cavity dowel features. This product is offered in D (shank diameter) values of 10, 13, 16, 20, 25 mm, and a fixed overall L of 80–130 mm depending on the chosen configuration.

• Point length (L1): Choose 13–19 mm or 19–25 mm to set the dowel seating engagement depth without over-penetration. L1 should suit your stack height and the distance to the dowel seating plane.
• Tip shape: Pick from H, J, K, L, N, O, R, V, X, Y, Z to match the mating dowel lead-in geometry and desired centering behavior.
• Fit-related dimensions: Configure P (4–18 mm), W (4–6 mm), and R (0.2–12.5 mm) to match the mating contact profile and required clearance.

Where tolerances and press-fit details depend on your dowel hole spec, validate engagement using your cavity/core datum and account for production tolerances on both punch and dowel bore.
