In aluminum extrusion manufacturing, tighter tolerances come with higher costs, as they require more precise tooling.

Choosing the appropriate tolerance can effectively control costs. Standard tolerances are suitable for most applications and offer high cost-effectiveness; tighter tolerances are recommended only when parts must fit together precisely.

We strictly adhere to ISO 9001-C standards: critical dimensions can be controlled within ±0.1 mm, while other dimensions are maintained within ±0.15 mm. We provide professional tolerance recommendations for your custom aluminum extrusion projects, helping you achieve the best balance between precision and cost—without paying extra for unnecessary high precision.
