This 15kHz 4200W system is purpose-built for large and thick-wall thermoplastic parts,.
• Large housings / structural covers
• Thick-wall joints requiring deep energy input
• Multi-rib or high-mass parts with long weld lines
This 15kHz 4200W system is purpose-built for large and thick-wall thermoplastic parts,
where standard 20kHz machines cannot deliver enough energy. Typical uses include:
• Automotive ducts & fluid reservoirs
• Large housings / structural covers
• Thick-wall joints requiring deep energy input
• Multi-rib or high-mass parts with long weld lines
Why This 15kHz 4200W Model
• Low-frequency, high-amplitude output enables deep melt penetration for heavy parts.
• 4200W power redundancy maintains stable welding under load fluctuations.
• Designed for high-strength joints with consistent collapse and reduced burn/whitening.
Case Snapshot

A. Adopting a new generation of digital circuits, the frequency is automatically tracked and locked to prevent frequency deviation during welding.
B. All pneumatic components are domestic well-known brands.
C. The frame adopts a large machine square column base, which is stable and prevents backward tilt.
D. The machine output amplitude strength can be adjusted steplessly, suitable for products with
different requirements, and it is more convenient and quick to adjust the mold.
E. The amplitude size adjustment achieved by intelligent closed-loop amplitude control technology
maintains a constant amplitude output under the influence of input power supply voltage and load fluctuations.
F. Multiple welding mode switching makes welding more accurate, applicable to a wider range, and has better welding effect.
G. Adopting a human-machine touch screen interface, digital welding parameter setting, intuitive and accurate.
H. Powerful output: The use of IGBT power modules and the structure of the self-excited oscillation
circuit make the output power more than 1.5 times that of the traditional self-excited circuit.
I. Intelligent protection and fault alarm prompts: mold current over-high protection, frequency offset protection,
and total output over-large protection. If the equipment fails, the generator will stop working immediately
and give a corresponding fault cause prompt until the technician eliminates the fault.
Compliance to Solid Wood Packaging Materials (SWPM) Regulations: The International Plant Protection
Convention(IPPC) and International Standards for Phytosanitary Measures no. 15 (ISPM's #15) guidelines
protect against insect infestation in packaging materials.
