The thickness tolerance of acrylic casting plate should meet the following standards:
Thickness of sheet (mm) | Thickness tolerance (mm) | Thickness of sheet (mm) | Thickness tolerance (mm) |
| 1.5 | ±0.2 | 11.0 | ±0.7 |
| 2.0 | ±0.4 | 12.0 | ±0.7 |
| 2.5 | ±0.4 | 13.0 | ±0.8 |
| 2.8 | ±0.4 | 15.0 | ±1.0 |
| 3 | ±0.4 | 16.0 | ±1.0 |
| 3.5 | ±0.5 | 18.0 | ±1.0 |
| 4 | ±0.5 | 20.0 | ±1.5 |
| 4.5 | ±0.5 | 25.0 | ±1.5 |
| 5.0 | ±0.5 | 30.0 | ±1.7 |
| 6.0 | ±0.5 | 35.0 | ±1.7 |
| 8.0 | ±0.5 | 40.0 | ±2.0 |
| 9.0 | ±0.6 | 45.0 | ±2.0 |
| 10.0 | ±0.6 | 50.0 | ±2.5 |
Note: When the plate size is between (1 700 mm x 1 900 mm) and (2 ooo mm x 3 000 mm), the thickness tolerance is allowed to increase by 20%.
When the plate size is greater than 2 ooo mm x 3 000 mm, the thickness tolerance is allowed to increase by 30%.
This standard is just as reference，because this the maximum thickness tolerance allowed in industry.In fact, Most of factories can offer less thickness tolerance.
Shandong HuaMing is acrylic sheet factory for 18 years, we can control the thickness tolerance less than +-0.2mm for sheet from 1.7-6mm because
Our production line only produces one thickness, and our molds are also specially customized, which can effectively control the thickness tolerance.
In addition, our workers have more than 10 years of production experience. From raw material weighing, filling, clamping molds, to mold edge sealing, every step is strictly controlled to ensure the minimum thickness tolerance.
