Branson Clean Joining technologies include:
Branson offers Clean Joining Technologies which offer clear-cut advantages over other methods for welding plastics:
Weld quality – Since there is no relative motion between the parts, no excitation or vibration, only the weld area is heated and melted, producing parts with excellent cosmetic properties.
Minimal flash and no particulate - Because the process can be easily controlled by varying the power of the laser source, it is possible to accurately control the power dissipation within the weld, resulting in less flash and no particulate.
Welds materials that are not easily welded with other welding technologies, including materials that have been successfully welded to date include PC, acrylics, PS, ABS, elastomers, polypropylene, high and low density polyethylene, PETG, and Nylon. The method also is effective with some dissimilar material combinations.
Part design flexibility - This method allows for 3-D joint configurations.
Pre-assembled parts can be welded. For some applications it is critical to allow internal components to be held in place during the welding process without becoming dislodged. This method allows for parts to be placed into the machine in the same position and orientation as the final, assembled position.
Ability to weld materials that are not easily welded with other joining technologies – Materials that have been welded successfully to date include acrylonitrile butadiene styrene, acrylics, elastomers, polycarbonate, polypropylene, polystyrene, high-density polyethylene, low-density polyethylene, polyethylene terephtalate glycol, and nylon. This method is also effective with some dissimilar material combinations.
Fast and flexible - Ideal for high volume applications; a typical weld cycle time ranges between 1 and 5 seconds.
