TABLE OF CONTENTS EMS-Chemie: Grilon, Grivory
Very good weld joints can be obtained for shaped parts made of Grilon and Grivory using heated element welding, ultrasonic welding, infrared welding, laser welding and vibration welding technology. The best results are achieved using ultrasonic welding. Vibration welding offers the possibility of welding amorphous and glass-reinforced Grivory.
Parts made of Grivory can be fastened well with self-tapping screws. Metric threads can be integrated directly into components.

BASF: Ultramid
Practically all methods developed for welding thermoplastics are suitable for Ultramid. The following welding methods are employed for moldings: ultrasonic, heating-element (thermal sealing, radiation welding), vibration (linear, biaxial), spin welding and laser beam welding. The newly developed Ultramid A3WG6 LT black 23229 provides the user with a highly developed product for laser welding applications.
Heat impulse and high frequency welding, in the case of suitable formulations, are preferably used for film. However, laser beam, heating-element and ultrasonic welding may also be used.

BIP Chemicals: Beetle
Nylon can be welded by all the processes normally employed for thermoplastics, such as friction welding and ultrasonic welding. The components should be dry prior to welding, since excessive moisture can reduce the strength of the bond.
