Master the Art of Glass Tempering: Expert Tips for Different Glass Types in a Glass Tempering Furnace
As a leading authority in the glass industry, LandGlass is here to provide valuable insights and guidance on successfully tempering various types of glass in a glass tempering furnace. With our expert tips, you can ensure exceptional results and maximize the quality and durability of your tempered glass products. Let’s delve into the specific considerations for different glass types:
1. Tempering Glass with Holes and Slots: Enhancing Strength and Performance
When working with glass that has holes or slots, it’s crucial to adjust the heating time to achieve optimal results. Increase the heating time by 2.5 to 5 percent compared to glass of the same size without holes and slots. This adjustment allows for uniform heating, ensuring consistent strength and performance across the glass surface.
2. Tempering Glass with Sharp Corners: Preventing Distortion and Bending
Glass with sharp corners requires special attention during the tempering process to prevent distortion and bending. To achieve this, position the sharp corners away from the direction of the furnace entrance. Additionally, place shattered glass pieces around the sharp corners to ensure slower and more controlled heat absorption. This technique prevents rapid heating of the corners, minimizing the risk of deformation and maintaining the integrity of the glass.
3. Tempering Patterned Glass: Preserving Surface and Pattern Integrity
When dealing with patterned glass, it’s essential to take specific precautions to preserve both the surface of the glass and the intricate pattern details. To prevent damage to the ceramic rollers, always position the glass with the patterned side facing upward during the tempering process. Moreover, determine the heating time and tempering air blow pressure based on the thickest part of the patterned glass. This meticulous approach ensures consistent tempering results while safeguarding the pattern and surface quality.
4. Tempering Coloured Glass: Achieving Vibrancy and Efficiency
Coloured glass requires slight adjustments in the tempering process to account for its higher heat absorption capacity. Typically, reduce the heating time by 5 percent compared to ordinary glass of the same size. By adapting the heating parameters, you can achieve vibrant and durable coloured glass while maintaining efficiency in your production process.
5. Tempering Coated or Heat Reflective Glass: Safeguarding Surface Films
When tempering coated or heat reflective glass, it’s crucial to protect the delicate surface film during the tempering process. To achieve this, ensure that the coated surface of the glass faces upward when entering the furnace. Additionally, adjust the heating temperature and heating time for the lower part of the glass. Increase these parameters by 2.5 to 10 percent compared to ordinary glass of the same size. By employing these measures, you can safeguard the surface film, maintain its integrity, and ensure the desired performance of the glass.
By following these expert tips from LandGlass, you can achieve exceptional results when tempering different types of glass in your glass tempering furnace. Unlock the full potential of your glass products by mastering the art of precise and tailored tempering techniques. Trust in LandGlass to be your partner in achieving superior glass tempering outcomes.
