Ultrasonic Textured Welding Head for Automotive Sound Insulation Cotton Welding

Welding of soundproof cotton for car interior

Automotive interior manufacturing widely adopts sound insulation cotton to optimize vehicle NVH performance and reduce driving noise. On-site sound insulation cotton fixing, edge sealing and defective product rework have become daily repetitive tasks for automobile production teams. When fixing automotive sound insulation cotton onto substrates, ordinary smooth ultrasonic welding tips often lead to insufficient friction energy. It is easy to cause weak welding, material slipping, burning or incomplete fusion during spot welding. Unstable welding results bring high reject rates, hinder assembly line operation and disrupt normal mass production. This welding head is also applicable to cotton textile materials, masks and welding tape processing scenarios.

Our Textured Spot Ultrasonic Welding Head Solution

Our textured spot ultrasonic welding head features an 8mm working end with dense anti-slip textured pattern. The special surface texture increases friction during ultrasonic vibration, effectively concentrating energy at the welding contact point. It achieves firm spot bonding between sound insulation cotton and base materials, avoiding material sliding while preventing excessive melting and perforation. The concentrated energy output guarantees stable welding quality during continuous production.

Core Advantages
  • 8mm welding working end with special textured anti-slip surface
  • Boost friction vibration, enhance bonding strength for soft fibrous materials
  • Reduce material slipping, burning and incomplete welding defects
  • Suitable for continuous mass production, lower defective rates
  • Compatible with handheld ultrasonic welding equipment
  • Wide applicability: soundproof cotton, cotton spinning fabrics, masks, welding tape
Application Scenarios

Spot welding of automotive sound insulation cotton; processing of cotton textile fabrics, disposable masks and welding tape.
