30kHz vs 35kHz: Key Differences
They differ by only 5kHz, but their applications are completely different:
1. 30kHz: Larger amplitude, higher energy
Better weld strength, stronger penetration
More stable on slightly thicker, stiffer fabrics requiring high strength
Slightly higher noise level than 35kHz
Suitable for: Ordinary non-woven fabrics
Thin non-woven fabrics requiring high tensile strength
Thickness: 0.1～0.3mm
Applicable to: Mask ear loops, ordinary underwear, regular non-woven products
2. 35kHz
Smaller amplitude, more precise, gentler
More concentrated heat, less prone to burning edges, holes, and yellowing
Lower noise
Suitable for: Ultra-thin, ultra-soft, easily damaged fabrics
Microfiber, medical dressings, films, transparent fabrics
Thickness: <0.1～0.2mm
For applications requiring extremely high aesthetic standards and no scorched edges
