Industry-leading dimensional accuracy, GD&T compliance, and rigorous quality verification for aerospace, automotive, and medical manufacturing.
Tolerances define the acceptable variation in a part's dimensions. At MetalCore, we don't just meet standards—we engineer processes to consistently exceed them. Our facility is equipped to handle tight tolerances across multiple manufacturing methods, ensuring your components fit, function, and perform exactly as designed.
Actual achievable tolerances vary based on material, geometry, and volume. Contact our engineering team for custom specifications.
| Manufacturing Process | Standard Tolerance (mm) | Standard Tolerance (in) | Typical Application |
|---|---|---|---|
| CNC Machining | ±0.005 mm – ±0.025 mm | ±0.0002" – ±0.001" | Aerospace, Medical, Precision Gears |
| Sheet Metal Fabrication | ±0.10 mm – ±0.25 mm | ±0.004" – ±0.010" | Enclosures, Brackets, Chassis |
| Injection Molding | ±0.05 mm – ±0.10 mm | ±0.002" – ±0.004" | Consumer Electronics, Medical Devices |
| Die Casting | ±0.10 mm – ±0.25 mm | ±0.004" – ±0.010" | Automotive, Industrial Hardware |
| Grinding / Honing | ±0.002 mm – ±0.005 mm | ±0.0001" – ±0.0002" | Hydraulic Cylinders, Bearing Seats |
* Tolerances tighter than ±0.005mm may require additional processing, specialized tooling, or extended cycle times. Surface finish (Ra) and material hardness also influence achievable precision.
We design and manufacture to ASME Y14.5-2018 standards, ensuring functional geometry rather than just dimensional limits.
Controls the exact location of features like holes and slots relative to datums. Critical for assembly alignment.
Ensures surfaces and axes remain within specified boundaries without reference to datums.
Controls rotational accuracy and axial alignment for shafts, bearings, and spinning components.
Guarantees precise angular relationships between mating surfaces and mounting planes.
Defines the allowable variation in 3D contour shape, essential for complex organic geometries.
Combines multiple geometric controls to restrict pattern and feature orientation simultaneously.
