Linear vibration friction is welcomed by automotive lighting because of its advantages of flexibility of welding and reliable welding performance. MP Sonic designs and manufacturing vibration welding jigs mostly for tail lamp, fog light, HLBL (high level brake light), run-through type rear light, mirror indicator, side indicator, corner indication, reflector, etc.

Besides welding strength and air-tightness for its reliability, it requests highly in protection to light length and dust control in side of lamp, as well as the flexible & complex design of automotive lamp design, there is challenges of automotive lighting not only to welding machine system, but also to vibration welding tooling design.

MP Sonic normally applies epoxy resin as the material of welding fixture contacting lamp length. The material of jig for housing normally basing on lamp’s structure design.

To control the dust might generated by linear vibration, as well as fit for the big bevel at interface of two parts against vibration welding direction, MP Sonic designs vibration welding tooling with infrared preheating tooling or super-frequency VIB welding system for customer selection.

Before final technical decide about welding to plastic parts, MP Sonic provide technical analysis service and proposal for customer in free.
