3. Ultrasonic Welding Physics: 20 kHz to 40 kHz
3.1 Wave Propagation in 3 Seconds
20 kHz = 17 cm wavelength in air, 7.5 cm in ABS. Energy directors focus 180 °C melt in 0.38 s.
3.2 Horn Design Rules (Copy-Paste)
Gain = λ/4 → Aluminum 7075 → Slot every 12 mm Booster 1:1 for 42 μm, 1:1.5 for 65 μm Tip: Ti-6Al-4V, Ra 0.4 μm
4. 82-Resin Compatibility Matrix
Green = no primer, Yellow = 5 % glass filler OK, Red = impossible.
