Processing Methods
Warm edge spacers are designed to integrate seamlessly into modern insulating glass production. Thanks to their flexible structure and stable material composition, they can be processed using various methods depending on the production scale, equipment, and glass design requirements.
NorseSpacer warm edge spacers support multiple processing techniques, enabling manufacturers to produce high-performance insulating glass units efficiently while maintaining excellent thermal performance and durability.
Manual processing
Manual processing is commonly used by small and medium-sized insulating glass manufacturers or for customized glass units.
With corner keys assemble warm edge spacers according to the required glass dimensions. The flexibility of the spacer material allows quick adjustment and precise positioning during assembly.
Advantages of manual processing include:
•Flexible production for small batch orders
•Suitable for customized insulating glass units
•Low equipment investment
•Easy integration into existing IG production workflows
This method provides an efficient solution for manufacturers who prioritize flexibility and customization.
(Ultrasonic) welding
For automated or semi-automated insulating glass production lines, spacer welding provides a reliable method to create continuous spacer frames.
Warm edge spacers can be precisely cut and welded at the corners to form strong and airtight joints. This process helps improve the structural stability of the spacer frame and ensures consistent spacing within the insulating glass unit.
Benefits of welding processing include:
•Strong and durable corner connections
•Improved air tightness of IG units
•Consistent frame dimensions
•Suitable for medium to large production volumes
Welding processing is widely used in modern insulating glass manufacturing where efficiency and consistency are essential.
Bending
Bending technology allows warm edge spacers to be formed directly into frames without the need for corner connectors.
Using automatic bending machines, the spacer can be shaped precisely according to the glass dimensions. This method reduces the number of joints and helps improve both the appearance and performance of the insulating glass unit.
Key advantages of bending include:
•Reduced number of corner joints
•Improved structural integrity
•Faster frame production
•Higher production efficiency
Bending processing is particularly suitable for manufacturers operating automated insulating glass production lines.
