Wear-Resistant Positioning Step Pin for Industrial Molds

The Wear-Resistant Positioning Step Pin for Industrial Molds from Qimao Metal Manufacturer because mold shops kept asking for a locating pin that wouldn’t wear out after a few thousand cycles. The regular ones work fine for a month or two, then the shoulder starts rounding off and you lose your zero. So we took a standard step pin, bumped up the hardness, added a tighter tolerance on the step diameter, and ran it through real shop floors before putting it on our catalog.

Product Parameter (Specification)

Product Feature

· Through-hardened steel, not just case-hardened – Most From Qimao Metal Manufacturer Wear-Resistant Positioning Step Pin for Industrial Molds get a thin hard layer that wears through fast. We harden all the way. The shoulder stays sharp even after tens of thousands of hits, so you don’t lose positioning accuracy halfway through a production run.

· Step diameter held to +/-0.01mm – That extra bit of precision means the pin locates the same way every single time. No wobble, no guessing. If your mold base or fixture plate has a reamed hole, this pin drops in and stays put.

· Wear-resistant surface without coating chipping – We skip the fancy coatings that peel off. Instead, we use a controlled heat treatment and finishing process that leaves a smooth, hard surface. It resists galling and scratching without adding thickness that changes the fit.

Application

· Injection mold tooling – Used the Wear-Resistant Positioning Step Pin for Industrial Molds as a core alignment pin that gets pulled and reinserted every shift. The wear resistance keeps cavity halves matching up without drift, especially on high-cavitation molds where multiple pins work together to hold position.

· Checking fixtures and gauges – For QC departments that need a repeatable locating point. The tight step tolerance means the pin gives you the same reference every time you place a part against it. No recalibration between batches.

· Quick-change pallet systems – Mounted on fixture plates that get swapped in and out of CNC machines. The hardened shoulder survives daily clamping and unclamping without mushrooming, so your pallet registers stay accurate over months of use.

Why Choose Our Factory

We’ve been cutting metal and grinding Wear-Resistant Positioning Step Pin for Industrial Molds for over twelve years, mostly for shops that don’t have time to argue with suppliers. Our factory runs on older but well-maintained CNC grinders — not the fastest, but consistent. Every step pin gets measured on a digital micrometer before packing. If the step diameter is off by more than two microns, it goes back to the grinder. We don’t have a huge marketing team, and we don’t pretend to. What we have is a heat treat line that actually follows the cycle time, inspectors who reject things, and a simple rule: if we wouldn’t use it in our own jigs, we don’t ship it.
