❓ Frequently Asked Questions
Q What do the dimensional tolerances in the table mean?

Dimensional tolerances refer to the allowable deviation in the length and width measurements of the material. For example, a tolerance of ±0.1 mm means the actual dimension can be 0.1 mm larger or smaller than the specified size, ensuring consistent quality across production batches.

Q Why do larger sizes have wider dimensional tolerances?

As the size of the piece increases, minor variations in the manufacturing process become more pronounced. Larger pieces such as 150×150 mm or 200×200 mm require slightly wider tolerances (up to ±0.5 mm) to account for material expansion, cutting precision limits, and process variability while still maintaining reliable performance.

Q What standard thickness options are available for small sizes like 10×10 mm?

For the 10×10 mm size, the available standard thicknesses are 0.5 mm, 1.0 mm, and 2.0 mm. Smaller sizes support thinner options because they are easier to manufacture precisely at reduced thicknesses without compromising structural integrity.

Q Can custom sizes or thicknesses be ordered outside the listed specifications?

The table reflects standard production specifications. Custom sizes and thicknesses may be available depending on order volume and technical requirements. It is recommended to contact the supplier directly to discuss custom specification options and associated tolerances.

Q What is the difference between dimensional tolerances and thickness tolerances?

Dimensional tolerances apply to the length and width (the flat plane dimensions) of the piece, while thickness tolerances refer to the allowable variation in the depth or height of the material. Both are critical quality parameters but are measured and controlled through different manufacturing processes.

Q Which size and thickness combination offers the tightest overall tolerances?

Smaller sizes such as 10×10 mm to 30×30 mm offer the tightest tolerances, with dimensional tolerances of ±0.1 mm and thickness tolerances as low as ±0.05 mm. These specifications are ideal for precision applications where exact dimensions are critical to performance and fit.
