Frequently Asked Questions
Q
What does the dimensional tolerance mean in this specification table?
A
Dimensional tolerance refers to the allowable deviation from the specified length and width measurements. For example, a tolerance of ±0.1 mm means the actual dimension can be 0.1 mm larger or smaller than the stated size, ensuring parts fit within acceptable engineering limits.
Q
Why do larger sizes have greater dimensional tolerances?
A
As the size of a part increases, maintaining the same absolute precision becomes more challenging due to material expansion, machining limitations, and cumulative manufacturing variations. Larger pieces such as 150×150 mm or 200×200 mm therefore carry a wider tolerance range of ±0.3 to ±0.5 mm.
Q
Which size options are available for a standard thickness of 5.0 mm?
A
A standard thickness of 5.0 mm is available for sizes 50×50 mm, 60×60 mm, 80×80 mm, 100×100 mm, 150×150 mm, and 200×200 mm. Smaller sizes such as 10×10 mm and 20×20 mm do not support the 5.0 mm thickness option.
Q
What is the thinnest available option and for which sizes is it offered?
A
The thinnest standard thickness is 0.5 mm, which is available for the smallest sizes: 10×10 mm and 20×20 mm. This ultra-thin option is suitable for applications requiring minimal material volume while maintaining precise dimensional control.
Q
How does thickness tolerance change as the part size increases?
A
For smaller sizes (10×10 to 50×50 mm), thickness tolerances range from ±0.05 to ±0.1 mm, offering tighter control. For mid-range sizes (60×60 to 100×100 mm), the tolerance is a consistent ±0.1 mm. For larger sizes (150×150 and 200×200 mm), the tolerance widens to ±0.1 ~ ±0.2 mm.
Q
Can custom sizes or thicknesses outside of the standard specifications be requested?
A
The table above lists the standard sizes and thicknesses available. For custom dimensions or special tolerance requirements beyond the listed specifications, it is recommended to contact the manufacturer or supplier directly to discuss feasibility, lead times, and any additional engineering requirements.
