Materials & Tolerance

Material selection and dimensional accuracy are at the core of our manufacturing strength. We machine a wide range of engineering metals and high-performance alloys with strict control over tolerances to ensure reliability, strength, and long-term performance of every component.

Materials We Machine

Materials We Machine

We specialize in machining both standard and exotic metals used in demanding industrial environments. Our material expertise allows us to optimize tooling, cutting strategies, and finishing methods for each grade.

Stainless Steels

  • SS304
  • SS316
Used for corrosion resistance, hygiene-critical applications, and structural durability.

Alloy & Carbon Steels


  • EN8
  • EN24
  • 42CrMo4 QT
Chosen for high strength, wear resistance, and load-bearing performance.

High-Performance & Exotic Alloys

  • Inconel
  • Duplex
  • Super Duplex
Used in extreme temperature, pressure, and corrosive environments—especially in Oil & Gas and heavy engineering sectors.

Non-Ferrous Metals

  • Aluminium
  • Brass
Ideal for lightweight applications, electrical components, precision fittings, and decorative or wear-resistant parts.
Machining Tolerance Capability

Machining Tolerance Capability

Sky Tech delivers precision machining with a typical tolerance capability of ±0.01 mm. This ensures:
  • Accurate part fitment
  • Reliable assembly performance
  • Reduced rework and rejection
  • Complete dimensional consistency across batches
Our tolerance control is supported by:
  • Stable CNC machining processes
  • Optimized cutting parameters
  • Controlled tooling systems
  • Regular in-process and final inspection
Surface Finish And Dimensional Stability

Surface Finish & Dimensional Stability

Beyond tight tolerances, we focus on:
  • Smooth surface finish
  • Burr-free edges
  • Stable geometry
  • Consistent dimensional behavior after secondary processing
This ensures components perform exactly as intended in real application environments.
Material Traceability and Verification

Material Traceability & Verification

Every critical component we machine is supported with material traceability using heat number tagging. This ensures:
  • Verified raw material authenticity
  • Complete production history tracking
  • Compliance with customer documentation requirements
  • Full accountability through the supply chain
Tolerance Control

Why Our Material & Tolerance Control Matters

  • Enables high-precision mechanical assemblies
  • Prevents premature wear and failure
  • Ensures safety in pressure and load-bearing systems
  • Guarantees repeatability for mass production
  • Improves product life and performance
