Metric Center Dowel Punches for Heavy Load XCDP Coating

Metric center dowel punches with a heavy-load geometry and an XCDP coating are used in injection mold tooling where die alignment must remain stable under repeated clamp cycles. They pair with matching bushings in transfer and progressive tooling to keep upper and lower die halves synchronized, reducing shear-to-shear position drift during high-volume runs.

In automotive connector and terminal molds, these punches help maintain repeatable cavity-to-core registration despite abrasive contaminants and continuous production wear. The XCDP surface is suited for environments that demand improved wear resistance while retaining reliable, repeatable seating.

• Heavy-duty die alignment: use when centering forces are high and dimensional repeatability matters.
• High-cycle assembly: XCDP coating supports longer service intervals by resisting surface wear.
• Metric mold bases: selection of D (10–25 mm) and L (80–130 mm) supports installation into standard metric tooling layouts.

The provided specifications describe tip shapes and dimensional ranges, including an XCDP coating, but no specific steel grade or hardness (HRC) data is included in the input. Therefore, material-property statements such as exact toughness, wear coefficients, or HRC cannot be verified for this SKU from the current dataset.

What can be stated from the product variant is that the XCDP coating is intended to enhance surface durability for heavy-duty alignment components. In die and mold service, coated dowels typically trade off a slightly altered surface compliance for better wear resistance, which helps preserve fit and centering accuracy over time.

• Coating state: XCDP coated (as specified); base-steel heat treatment not provided.
• Trade-off: improved wear resistance to support longer tool life; exact toughness/hardness balance depends on the underlying steel and heat treatment.

Select the dowel punch size by matching its metric shank diameter D and overall length L to the corresponding bushing and guide pocket in your mold base design. This series offers D = 10, 13, 16, 20, or 25 mm, and a fixed L = 80–130 mm range.

Then choose the alignment and engagement geometry using the variable dimensions P (1.5–18 mm), W (1.5–6 mm), and R (0.2 up to 12.5 mm). The tip shape (H, J, K, L, N, O, R, V, X, Y, Z) should be selected to match the mating bushing profile and the desired lead-in behavior during mold closing.

• Match fit: ensure D corresponds to the bushing bore size and the intended clearance/interference for your alignment strategy.
• Engagement depth: confirm L and L1 (point length 13–19 mm or 19–25 mm) provide sufficient guidance without bottoming.
• Tolerance note: because no tolerance values are provided, use your drawing’s GD&T and bushing tolerances to verify final fit.
