Q
What do the dimensional tolerances mean in this specification table?
Dimensional tolerances indicate the allowable deviation from the stated length and width measurements. For example, a ±0.1 mm tolerance on a 10×10 mm piece means the actual dimension may range from 9.9 mm to 10.1 mm. Tighter tolerances ensure better fit and assembly precision in applications requiring close-fitting components.
Q
Why do larger sizes have wider dimensional tolerances?
As the size of a piece increases, minor variations in raw material and machining processes accumulate, making it inherently more challenging to maintain the same absolute tolerance. Larger pieces (such as 150×150 mm or 200×200 mm) therefore carry wider tolerances (up to ±0.5 mm) while still meeting stringent quality standards for their respective applications.
Q
How should I choose the right standard thickness for my application?
The ideal thickness depends on the structural requirements, weight limits, and thermal or mechanical load of your application. Thinner options (0.5–1.0 mm) suit lightweight or space-constrained designs, while thicker options (3.0–5.0 mm) provide greater rigidity and durability for demanding environments. Consulting with our technical team is recommended for critical applications.
Q
Are custom sizes or thicknesses available beyond the listed specifications?
Yes, custom dimensions and thicknesses can be manufactured upon request. Standard sizes and thicknesses listed in the table represent our most commonly stocked options. For non-standard requirements, please contact our sales team with your specifications, and we will provide a feasibility assessment and quotation accordingly.
Q
What quality control measures are used to verify dimensional and thickness tolerances?
Each batch undergoes rigorous inspection using calibrated precision instruments, including digital micrometers and coordinate measuring machines (CMM). Both dimensional (length/width) and thickness tolerances are verified against the values listed in the specification table to ensure every piece meets the stated accuracy requirements before shipment.
Q
Which size range offers the tightest overall tolerances for high-precision applications?
The smaller size ranges — particularly 10×10 mm to 30×30 mm — offer the tightest dimensional tolerances of ±0.1 mm and thickness tolerances as low as ±0.05 mm. These are ideal for high-precision applications in electronics, optics, and fine mechanical assemblies where accuracy is critical.
