Center Dowel Regular Punches - Metric XCD Coating

In injection mold tooling, these center-dowel regular punches are used as alignment and ejector-support elements to maintain die-to-die positional accuracy under repeated cycling. They’re commonly specified for progressive and transfer die sets, where stable punch guidance directly impacts part geometry and scrap rates.

• Automotive connector and terminal dies: Use the metric shank geometry to ensure repeatable tool seating and consistent ejector/punch alignment during high-speed production runs. The XCD coating variant supports wear resistance at sliding interfaces.
• Medical device housing and insert tooling: Apply center-dowel punches to control alignment of core/cavity components and reduce variation in ejection features. The regular center-dowel design helps maintain stable guiding action across cycles.
• Consumer electronics enclosures: When multiple tool stations demand tight repeatability, choose the available tip shapes and point lengths to match specific guiding engagement and minimize misalignment.

The XCD coating’s wear resistance makes this variant particularly suited for long service intervals where guidance surfaces experience frequent contact and load.

The provided data identifies the product as an XCD-coated center-dowel punch variant; however, no specific steel grade (e.g., SKD61/H13, XW-? tool steel) or hardness value is listed in the specifications you supplied. Therefore, hardness (HRC), quench & temper state, nitriding, and base-material heat treatment cannot be stated without additional input.

• XCD coating function: XCD surface coating is selected to improve wear resistance at guidance/contact regions, supporting consistent alignment over time.
• Typical trade-off (material-agnostic): Coated guidance parts generally prioritize abrasion resistance, while toughness is governed by the underlying steel’s heat treatment and core hardness.

If you share the underlying steel grade and heat treatment condition, we can map it to the relevant standard equivalents and confirm the expected HRC/hardness and toughness balance.

Selection starts by matching the shank diameter D and overall length L to the corresponding die bushing/recess geometry. Available values are D = 10, 13, 16, 20, 25, or 32 mm and L = 71 to 150 mm (fixed range per the product family).

• Point engagement: Choose L1 (point length) from 19 to 25 mm or 25 to 30 mm to achieve the required guiding depth without over-interference.
• Tool interface features: Verify P = 4 to 16 mm and W = 4 to 10 mm against the locating geometry of the mating components.
• Edge/curvature: Confirm the selected R dimension range (available options include 0.2–4.975, 0.2–6.475, 0.2–7.975, 0.2–9.975, 0.2–12.475, 0.2–15.975) and the selected tip shape (H, J, K, L, N, O, R, V, X, Y, Z).

For fit, ensure your design maintains proper clearance in alignment holes/bushings for repeatability; exact tolerance values are not provided in the input, so validate fits using your internal drawing tolerances and the mating part specification.
