Ultrasonic Welding Specification Targets for Buyers
Setting Ultrasonic Welding correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Ultrasonic Welding next to composition and weight so all three are quoted as one package. Working figures for Ultrasonic Welding normally sit around no thread required in mainstream production. Note welding machine with rotary horn on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: no thread required. Record elastane content alongside Ultrasonic Welding, because blends shift the measured value. A result outside no thread required usually points to process drift rather than to the fibre itself.
Tolerances that work
Allow a small tolerance rather than a fixed number, since normal process variation exists in every lot. Keeping reference values for Ultrasonic Welding lets suppliers quote without extra sampling rounds. Ask for conditioning details together with welding machine with rotary horn, since both affect the reading.
Verification method
Confirm with welding machine with rotary horn and keep the report against the bulk record. Working figures for Ultrasonic Welding normally sit around no thread required in mainstream production. Note welding machine with rotary horn on the tech pack so nobody tests against an older revision.
Commercial note
Tightening beyond practical need raises cost without improving garment life, so set the tightest target only where it protects the customer. Record elastane content alongside Ultrasonic Welding, because blends shift the measured value. A result outside no thread required usually points to process drift rather than to the fibre itself.
