Jigs & Fixtures

Significantly increasing the surface life of clamping faces, locating pads, and alignment pins to maintain precise reference points and strict tolerances.

The Challenge and Solutions

Jigs and fixtures are often handled frequently, clamped repeatedly, and exposed to shop-floor debris and chemical contaminants. Over time, surfaces can wear down, leading to loose fits and tolerance errors.

Shital Plasma Nitriding significantly increases the surface life of these critical tools, ensuring that your reference points remain accurate and stable.

How We Solve Jigs & Fixtures Challenges

Problem Faced Mechanism of Plasma Nitriding Solution
Scratch Mark Produces a hard, non-galling surface that prevents scoring from clamped workpieces, maintaining the integrity of locating pads and contact surfaces.
Wear & Tear Provides exceptional resistance to mechanical erosion and repeated contact stress, ensuring that clamping faces and alignment pins maintain their original dimensions.
Corrosion of Fixtures Creates a metallurgical barrier that protects fixtures from oxidation and environmental moisture, which is essential for tooling stored in between production batches.

Material Specifications for Jigs and Fixtures

Jigs and fixtures are frequently made from carbon and alloy steels that require a balance between hardness and structural stability. The following specifications ensure that your work-holding tools remain hardened and precise for high-cycle industrial use.

Material / Grade Application Area Target Surface Hardness Recommended Case Depth
Mild Steel (IS 2062 / EN8) General Jig Bodies 500 – 650 HV 0.25 – 0.50 mm
EN19 / AISI 4140 Locating Pins & Bushings 650 – 800 HV 0.20 – 0.40 mm
EN24 / AISI 4340 High-Stress Fixture Blocks 700 – 850 HV 0.20 – 0.40 mm
Stainless Steel (300 Series) Corrosion-Resistant Fixtures 900 – 1050 HV 0.10 – 0.20 mm
Low Alloy Steels - 16MnCr5 / 20MnCr5 Guide Pillars / Locating Pins 600 – 700 HV 0.10 – 0.25 mm
MS / C45 / En8 Guide Pillars / Locating Pins 300 – 450 HV 0.05 – 0.10 mm
Mild / Carbon Steel General Machine Brackets 550 – 700 HV 0.25 – 0.50 mm
Note: For jigs and fixtures, minimizing dimensional distortion during the treatment process is key. Our low-temperature plasma nitriding process is ideal for finished-machined tooling, as it allows for hardening with virtually no change to the critical dimensions of your fixtures.
