Metric Center Dowel Punches for Heavy Load with XVP Coating

Center dowel punches with XVP coating are used to establish repeatable locator alignment in heavy-duty injection mold and stamping tooling. They are commonly installed in shut-off and tie-bar guided mold assemblies to ensure consistent punch-to-block positioning during press cycles.

• Automotive connector and bracket molds: When alignment stability directly impacts gate/insert positioning, the heavy-load geometry helps maintain locating accuracy under vibration and repeated clamping.
• Medical device housings with tight part-to-part registration: Use these center locators to stabilize mold half alignment, supporting consistent cavity location for thin-wall or fine-feature components.
• Industrial housings and appliance casings: The XVP coating is selected to improve wear resistance at the locating interface, helping maintain smooth operation across long service intervals.

Choose the appropriate metric shank diameter and tip form from the available options to match your dowel-hole geometry and ensure reliable seating within the mold assembly.

The provided product data specifies an XVP coating for improved wear behavior at the dowel/punch locating surfaces. While the steel grade and hardness (HRC) are not specified in the input, the engineering intent is clear: the coated locating interface reduces abrasive wear and supports consistent punch operation over long production runs.

• Wear resistance: XVP coating is used to maintain dimensional stability at the locating point and minimize rounding or surface damage.
• Toughness trade-off: For heavy-load locating, the system prioritizes durable contact performance; however, exact toughness vs. hardness balance depends on the underlying steel grade, which is not provided.
• Heat treatment state: No heat treatment details (e.g., quenched & tempered, nitrided) were included in the provided specifications.

If you need confirmation of steel grade equivalence and target hardness for your application, share your preferred operating load and cycle life expectations so the correct material/condition can be verified.

Select dimensions to match the mating dowel-hole and locator features in the mold base to ensure the punch seats correctly and maintains alignment.

• Choose shank diameter (D): Available D values are 10, 13, 16, 20, 25 mm. Match this to the corresponding hole diameter design on the mold block/plate.
• Select tip/probe form: Tip shape options include H, J, K, L, N, O, R, V, X, Y, Z. Use the form that best suits your locating engagement length and lead-in geometry.
• Set point length (L1): L1 ranges are 13–19 mm and 19–25 mm. Pick based on required engagement depth during mold clamping.
• Confirm overall length (L): L is fixed at 80–130 mm. Ensure clearance for installation and that the working tip can reach the locator surface without interference.

Pay attention to P (4–18 mm), W (4–6 mm), and R (0.2–5 / 0.2–6.5 / 0.2–8 / 0.2–10 / 0.2–12.5 mm) to align with your dowel-hole lead-in radii and tolerance/fit strategy. When dowel-hole tolerances are tight, ensure the selected tip form and shank diameter correspond to the intended clearance or press-fit condition used in your tooling design.
