💬 Frequently Asked Questions
❓What do the dimensional tolerances in this table represent?
✅Dimensional tolerances indicate the allowable deviation from the specified length and width measurements. For example, a tolerance of ±0.1 mm means the actual dimension may be up to 0.1 mm larger or smaller than the stated size.
❓Why do larger sizes have wider dimensional tolerances?
✅As the size of a part increases, the cumulative effect of material properties, thermal expansion, and machining limitations naturally results in slightly wider tolerances. This is standard practice in precision manufacturing across all industries.
❓Can I request a custom thickness that is not listed in the Standard Thickness column?
✅Yes, custom thickness options may be available depending on the material and size. Please contact our technical team with your specific requirements, and we will assess feasibility and provide a tailored quote.
❓What is the difference between dimensional tolerance and thickness tolerance?
✅Dimensional tolerance refers to the acceptable variation in the length and width of the part, while thickness tolerance refers to the permissible deviation in the depth or height of the material. Both are critical for ensuring proper fit and function in precision applications.
❓Are these tolerances compliant with international standards?
✅Our tolerance specifications are designed to align with commonly accepted international manufacturing standards. If your project requires compliance with a specific standard such as ISO, DIN, or JIS, please inform us so we can confirm compatibility or make necessary adjustments.
❓Which size and thickness combination offers the tightest overall tolerances?
✅Smaller sizes such as 10×10 mm and 20×20 mm offer the tightest tolerances, with dimensional tolerances of ±0.1 mm and thickness tolerances as low as ±0.05 mm. These are ideal for applications requiring the highest level of dimensional precision.
