🔹
What do the dimensional tolerances in this table mean?
✅
Dimensional tolerances indicate the acceptable range of deviation from the specified length and width. For example, a tolerance of ±0.1 mm means the actual dimension can be up to 0.1 mm larger or smaller than the stated value, ensuring consistent fit and performance in precision applications.
🔹
Why do larger sizes have greater dimensional tolerances?
✅
As the size of a piece increases, maintaining the same absolute tolerance becomes more challenging due to material behavior, thermal expansion, and manufacturing process limitations. Therefore, larger dimensions such as 150×150 mm and 200×200 mm naturally carry slightly wider tolerances (±0.3 ~ ±0.5 mm) compared to smaller pieces.
🔹
Are custom sizes available beyond those listed in the table?
✅
Yes. The table lists our standard size offerings. Custom dimensions outside of these specifications can be produced upon request. Please contact our technical team with your specific size and tolerance requirements, and we will provide a feasibility assessment and quotation.
🔹
What standard thicknesses are available for the smallest size (10×10 mm)?
✅
For the 10×10 mm size, standard thicknesses of 0.5 mm, 1.0 mm, and 2.0 mm are available. The thickness tolerance for this size ranges from ±0.05 mm to ±0.1 mm, making it suitable for applications requiring very fine precision.
🔹
How should I select the right thickness for my application?
✅
The appropriate thickness depends on your application's mechanical load requirements, thermal management needs, and space constraints. Thinner options (0.5–1.0 mm) are ideal for compact assemblies, while thicker options (3.0–5.0 mm) provide greater structural rigidity and heat dissipation. Our engineering team can assist with material selection recommendations.
🔹
Are the thickness tolerances the same across all sizes and thicknesses?
✅
Not exactly. Thickness tolerances vary depending on both the size and the specific thickness value. Smaller pieces with thinner profiles typically achieve tighter tolerances (±0.05 mm), while larger or thicker pieces may have tolerances up to ±0.2 mm. The table provides a clear reference range for each size category.
