Center Dowel Punches for Heavy Load - Metric, XCD Coating

These heavy-load center dowel punches are used in injection mold tooling and progressive die line setups where repeatable center alignment is critical for each cycle. They guide punch-driven locating between die halves, tooling carriers, or press frames to reduce gradual misalignment caused by vibration and high press tonnage.

In automotive connector and terminal molds, the XCD-coated working surface helps resist fretting and wear on the locating point, supporting stable part-to-part positioning during high-volume runs. Tip geometry options (X, R, K, O, H, L, J, N, V, Y, Z) allow engineers to match the locating contact profile to their cavity/core lead-in and register hole features.

For medical device housing and insert molds, where tight cosmetic and dimensional consistency are required, the metric shank diameter range (10–25 mm) supports a secure guided fit in standard die layouts while the available point length windows (13–19 and 19–25 mm) help tune penetration depth without over-stressing the guide interface.

The provided specification set for this series focuses on geometry and coating; no steel grade, heat treatment, or measured hardness is stated in the input data. For this reason, material hardness (HRC), quenched & tempered condition, nitriding, or other heat-treatment specifics cannot be claimed without sourcing the corresponding technical sheet.

What can be supported by the metadata is the XCD coating itself: it is intended to enhance wear resistance and maintain stable locating under production loads. In heavy-load alignment applications, this typically improves resistance to surface scuffing and reduces wear-driven positional drift.

• Coating impact: Prioritizes wear life at the locating interface, helping preserve repeatability over more cycles.
• Trade-off: Coatings are most beneficial for wear-dominant regimes; if impact/bending becomes dominant, base material toughness and fit quality become more critical than coating alone.

Select the dowel punch dimensions to match the locating/register geometry of the mating die halves while controlling penetration depth and side loading.

1) Shank diameter (D): Choose from the specified metric range D = 10, 13, 16, 20, or 25 mm to fit the corresponding die guide bore/hole diameter used in your tooling layout.

2) Point length (L1): Use either L1 = 13–19 mm or L1 = 19–25 mm based on how far the locating point must engage into the mating feature for repeatable center reference without excessive travel.

3) Overall body length (L): Confirm your tooling envelope against the fixed range L = 80–130 mm.

• 4) Tip profile (shape): Match the selected contact geometry (H, J, K, L, N, O, R, V, X, Y, Z) to the register feature shape so alignment is repeatable across cycles.
• 5) Additional dimensions: Verify P = 4–18 mm, W = 4–6 mm, and the specified R ranges (0.2–5 up to 0.2–12.5 mm) correspond to your mating lead-in radii and contact pattern.

For best stability, ensure the chosen D and tip engagement meet your assembly tolerances; even with wear-resistant coating, excessive clearance can increase register variation.
