RX Coating Center Dowel Locating Punches - Metric

RX center dowel locating punches are used in injection mold tooling and related precision machining to control punch-to-work alignment through dedicated dowel holes. They are typically installed in a punch plate or machining fixture where repeatable registration is required between multiple hole features.

• Automotive connector & wire-harness housing molds: Use the locating punch to stabilize center positioning when punching or drilling runner, vent, and post-processing holes. The dowel-hole guided alignment helps keep hole layout straight across production lots.
• Medical device mold components: When building tight-tolerance features on small housings, the stable center location reduces drift during repeated machining cycles.
• Thin-wall electronics/precision inserts: For parts that are sensitive to misalignment, the locating geometry supports consistent punch performance while coordinating with existing dowel patterns.

This RX coating center design is suited to these applications because it improves wear behavior and maintains dimensional stability during repeated hole punching and fixture indexing.

The provided specifications describe the locating punch geometry and coatings but do not specify the underlying steel grade, hardness (HRC), or heat-treatment condition. Therefore, material property claims such as exact HRC, wear-resistance performance, or tempering/quenching states should be confirmed with the supplier’s drawing for the exact variant used in your build.

• RX coating: The “RX coating” is called out as part of the design intent to resist wear and support stable punch performance under repeat cycles.
• Trade-offs: Without the steel grade and heat-treatment data, the relationship between toughness and hardness (typical for tool steels) cannot be accurately quantified for this product.

If you provide the steel grade or allow access to the part drawing/spec sheet for series 110100282540, the response can be updated with the exact equivalent grade, target hardness, and any secondary treatments (e.g., nitriding) for engineering verification.

Select the locating punch dimensions to match the center-pointing function of the mold’s dowel-hole pattern and the required hole-feature location accuracy. Start by choosing the D (shank diameter) in the available range of 10 ~ 45 mm, ensuring the shank fits the receiving guide/bushing without interference.

• Choose the P (tip dimension) from 2.5 ~ 35 mm based on the mating dowel-hole geometry in your punch plate or fixture.
• Select L (length dimension) from the provided ranges (e.g., 50~150, 60~150, 40~150, 70~150, or 80~150) so the tip engagement depth is sufficient for stable registration.
• Use LC (full length change) and PC (tip dimension change) to verify variation limits across the selected configuration.

Match tip shape (Round, Rectangle, Oblong, Double flatted round, Radius rectangle) and corner radius R = 0.15 mm to your dowel-hole center geometry. For tolerance and fit, confirm your mating bore tolerance class; the series specifies dimensional ranges, but specific fit grades are not included in the provided data.
