Definition and Process Objectives of Folding the Fabric Surface of Wireless Charger Shell
The folding and pressing of the fabric edge of the wireless charger casing refers to the process of enhancing the appearance precision and structural stability by folding and pressing the edges of the fabric material. ?
?
Its core objectives include:
Ensure the flatness and aesthetics of the edges of the fabric material, avoiding burrs or looseness; ?
Reduce the risk of wear or detachment caused by friction during long-term use by reinforcing with folded edges; ?
Enhance the adhesion between the outer shell and internal components, and optimize the overall durability of the wireless charger. ?
??
Key technology implementation methods
Folding structure design:
Set up bending grooves or reserve folding sections at the edges of the fabric to reduce the risk of deformation caused by concentrated folding stress; ?
When using multi-layer composite fabrics, synchronous folding and bonding of different materials are achieved through hot pressing technology. ?
??
Quality control requirements:
After folding, tear resistance testing is required to verify the edge bonding strength; ?
Conduct weather resistance assessment on the folded area (such as stability in high temperature/humidity environments). ?
?
Comparison of Related Technologies
Similar processes can be seen in the side edge sealing treatment of lithium battery soft pack shells (such as separating folding sections through bending grooves to disperse stress); ?
In the structural design of the foldable wireless charging device, the folded edge of the fabric can be combined with the buckle mechanism to achieve compact storage.
