Vibration Welding Machine

Vibration Welder - LS Series 285Hz

Vibration Welder - LS Series 285Hz


MSV-LS series medium vibration welders cover vibration welding machine with upper fixture loading ability from 15~70KG. Machine applies vibration system in MP Sonic Brand in frequency max to 285Hz. Machine is applied to weld parts in challenging geometric design and thermoplastic material as well as challenging requirement in welding result.

Machine applies servo hydraulic system to force welding in high clamp pressure, welding depth is precision controlled by close-loop system.

Machine is mostly applied for manufacturing of automotive parts and house appliance.
