Ultrasonic Plastic Welding Machine for Charger from altrAsonix is a purpose-built solution for manufacturers producing mobile chargers, USB adapters, travel chargers, and small power supply housings. Compact charger body parts require precise control, clean joining, and rapid cycle time—making 20 kHz ultrasonic welding the ideal technology.
Why This Machine Suits Charger Welding
Charger housings are typically made from ABS or PP, both of which weld perfectly at 20 kHz frequency. This frequency provides stable vibration, excellent energy transfer, and prevents material cracking or burn marks—ensuring a smooth and durable finish.
Optimized for Electronics Manufacturing
Since charger welding demands accuracy around PCB placement, enclosure locking, safety insulation, and high-grade visual finishing, the analog system delivers highly repeatable welds with manual or semi-automatic operation. It eliminates gaps, improves safety compliance, and allows tamper-proof sealing.
