Tolerance Range for Tempered Glass Products
Manufacturers use tolerance range to determine if tempered glass products meet their standards. The reasonable range ensures that the finished products are qualified. However, how to reduce the tolerance range to improve quality? Check out this article!
Manufacturers in the tempered glass industry have always relied on their tolerance range to determine the quality of tempered glass products. The range is a measure of the acceptable margin of error or deviation that the finished product may have from the specified dimensions and properties. Now we are going to first introduce the reasonable tolerance for tempered glass products allowed in their manufacturing, like the thickness tolerance, dimension tolerance:
Thickness Tolerance for Tempered Glass Products:
1. for the tempered glass products with thickness 3~6mm, the allowed thickness tolerance is ±0.2mm.
2. for the tempered glass products with thickness 8~10mm, the allowed thickness tolerance is ±0.3mm.
3. for the tempered glass products with thickness 12~15mm, the allowed thickness tolerance is ±0.4mm.
4. for the tempered glass products with thickness 19mm, the allowed thickness tolerance is ±1.0mm
Dimension Tolerance for Tempered Glass Products:
1. the allowed tolerance of the side length of rectangular flat tempered glass products is as follows:
1.1. for tempered glass products with a thickness 3~6mm, the allowed tolerance of side length is ±3mm.
1.2. for the tempered glass products with a thickness 8~10mm, the allowed tolerance of side length is ±4mm.
1.3. for the tempered glass products with a thickness 12~15mm, the allowed tolerance of side length is ±5mm.
2. the allowed diagonal tolerance of rectangular flat tempered glass products is as follows:
2.1. for the tempered glass product with a thickness 3~6mm, the allowed diagonal tolerance is ±3mm.
2.2. for the tempered glass product with a thickness 8~10mm, the allowed diagonal tolerance is ±4mm.
2.3. for the tempered glass product with a thickness 12~15mm, the allowed diagonal tolerance is ±5mm.
Other Quality Inspection Standard for Tempered Glass Products:
1. Burst Inspection:
The allowable length in each side of each piece of tempered glass sheet shall not exceed 10mm per meter, and its depth extending from the edge of the tempered glass to the glass plate shall not exceed 2mm, and the depth extending from the plate to the glass thickness shall not exceed one-third of the thickness of the tempered glass. and this allowable burst can not appear more than one place.
2. Bubble Inspection:
The number of circular bubbles with a diameter less than 0.5mm is less than 5 pc/㎡, the number of bubbles with a diameter of 1mm is less than 2pc/㎡, and the bubbles with a diameter of 2mm are not allowed to exist. the rectangle bubbles with length 1.5mm, width 0.5mm, are less than 3pc/㎡.
3. Scratch Inspection:
The number of scratches allowed on the tempered glass surface per square meter with a depth less than 0.5mm, a width less than 0.1mm, and a length less than 30mm is not more than 3pc/㎡.
4. Light Transmittance Inspection:
The transmittance of tempered glass in the visible light band is not less than 91%.
These quality standards and requirements ensure the quality and safety of tempered glass and comply with relevant national standards.
However, tempered glass manufacturers today are looking for ways to reduce the tolerance range further, thereby ensuring that the finished products are of even higher quality.
Reducing the tolerance range is important because tempered glass products have to meet a set of strict industry standards. Recognizing this, manufacturers are figuring out innovative ways to achieve the necessary precision in their products. In the current market, tempered glass is used extensively in commercial and industrial applications as well as in residential construction. The tempered glass market is expected to grow at a Compound Annual Growth Rate (CAGR) of 4.3% from 2020 to 2025, according to a recent industry report.
Strategies to Reduce the Tolerance Range for Tempered Glass Products:
There are various strategies that manufacturers are exploring to reduce the tolerance range and improve the quality of their products. One approach involves switching to automated manufacturing processes, including robotic cutting and handling. This would enable manufacturers to achieve superior precision in the production process, reduce the occurrence of defects, and limit the need for manual intervention, which can be a source of variability.
Another strategy is to adopt smart glass technology that allows electronic control of the optical properties of the glass. Using smart glass technology would help manufacturers create customizable, high-quality tempered glass products that offer superior clarity, energy efficiency, and durability.
Moreover, some manufacturers are looking to incorporate the latest cutting-edge technologies like artificial intelligence (AI) and machine learning (ML) into their production lines. These technologies can be used to analyze past production data, identify patterns in the manufacturing process, and optimize production parameters to reduce the tolerance range continuously.
Conclusion:
The increasing demand for high-quality tempered glass products is driving innovation in the industry. With growing competition, manufacturers are going the extra mile to reduce the tolerance range and improve product quality.
In conclusion, tempering glass wisely requires a careful balance of various parameters, and controlling every single variable is critical in producing high-quality tempered glass products. Manufacturers looking to stay ahead in the market are continuously innovating and exploring value-added solutions to improve their quality and reduce the tolerance range. These strategies, coupled with the booming construction industry and the increasing focus on safety and security, will likely continue driving growth in the tempered glass market in the future.
