Standard Tolerances For Acetal
What is material thickness tolerance?
A material thickness tolerance is the allowable variation between a material's nominal thickness and its actual measured thickness. Because we work to nominal thicknesses, the material you receive will vary slightly from the figure on the spec sheet.
Why it matters at the design stage
Choosing material thickness is usually one of the first steps a designer takes when starting a project. Proper tolerances ensure that parts fit together seamlessly, which is especially important for assemblies.
