Single-Heel Guide Rails (HPM2T Steel) - No Groove

These single-heel guide rails are used in injection mold tooling wherever a slide or moving plate needs smooth, stable linear guidance without relying on an internal oil channel.

• Automotive connector and bracket molds: In core/cavity slide stages, the no-groove heel geometry supports consistent contact during repeated cycles, helping maintain alignment and reducing the risk of uneven wear from oil-path misapplication.
• Packaging and appliance housings with guided inserts: When assembly space is tight and lubrication routing is simplified, the rail’s non-oil groove option is suited to clean, controlled motion for ejector slides and undercut handling components.
• Automation modules and transfer fixtures: The nitriding-treated running surface improves wear resistance, supporting long service life for guided linear movement in machinery that cycles frequently.

Choose this variant when you want nitriding-enhanced durability plus a rail heel design that fits assemblies where oil grooves are not required.

The rail body is made from HPM2T steel, selected for tooling-grade wear performance in guided motion applications. The meta description specifies a nitriding-treated rail surface, which forms a hard, wear-resistant case on the contact area while keeping the base metal tougher and more shock-tolerant than a fully through-hardened option.

• Surface wear resistance: Enhanced by nitriding for stable running performance over repeated cycles.
• Toughness vs. wear trade-off: Nitriding typically prioritizes surface hardness and abrasion resistance while preserving core toughness, which is beneficial for sliding components that see intermittent loads.
• Manufacturing process: Steel fabrication and machining are followed by nitriding to build the hardened surface layer on the rail that interfaces with the slide plate/fixture.

If you choose a non-oil groove option, lubrication strategy is simplified, making the nitrided surface even more important for consistent wear behavior.

Select rail thickness T, heel height, and heel width to match the mechanical envelope and the mating slide/undercut interface in your mold assembly.

• Rail thickness (T): Choose 20, 25, or 30 mm based on available space and required stiffness for your moving plate.
• Rail length (L): Fixed range is 60 to 150 mm. Match this to the required guided stroke and the effective contact length in the slide stage.
• Heel height: Select 5 or 8 mm to ensure proper heel contact geometry with the mating component.
• Heel width: Select 3.5 or 8 mm to align with the rail seat/contact region.

Also confirm the oil groove setting: oil groove or non-oil groove. If your mold design expects an oil channel, use the oil-groove variant; otherwise, choose non-oil groove to prevent mismatch in lubrication pathways. Tolerance/fit values are not provided in the available specs, so verify clearance and mounting fit against your slide plate machining drawings.
