MSV-830LS & MSV-930LS is a vibration plastic welder in a super big specification which is designed to weld plastic parts in challenging measurement and material. MSV-830LS linear vibration welder is mostly applied for the assembling of automotive dashboard, such as welding air-duct, conditioner air channel, airbag, screen demist duct, , etc. Machine is designed with orbital construction to meet complex dashboard geometric design. Machine applies servo hydraulic to control forcing pressure during vibration welding, linear sensor is applied to inspect and control vibration welding depth. Welding process steps control is available for perfect welding result.
