Cutting and plastic welding for the automotive industry: ultrasonic, hot plate, infrared, laser, and spin processes

As the leading market for welding applications, the automobile industry continues to significantly contribute to the development of SONIMAT. Historically associated with ultrasonic welding, our teams have developed robust, fast and precise solutions for this sector for thermoplastic welding using hot plate, infrared, laser and spin technologies.

Faced with the required production volumes, standards and rules in force, the specificities and environment of each automotive part, our thermoplastic welding solutions are popular with the largest manufacturers (Plastic Omnium, Akwel, Continental, etc.).

Our teams are also upstream of each of your projects in order to give you the advantage of our vast experience. In the engineering and pre-project phase, we support you by understanding your requirements, the mechanical specificities of your parts and we actively participate in the study of your joint plans, parts design as well as in the selection of the most suitable welding technology. This development cooperation is also reflected in our ability to manage the complete prototyping phase (material approval, creation of moulds, etc.) up to the offline pre-series phase.

Our understanding of the needs of the automotive sector has led us to develop a full range of thermoplastic welding machines and presses: ultrasound, spin, laser, infrared, hot plate welders. All fully digital, they provide perfect welding quality and robust, airtight parts with great mechanical strength.

In addition to our assembly solutions, ultrasonic finishing and cutting of composite and complex materials is possible with our embeddable automated solutions.

Finally, our ultrasonic metal welding expertise and solutions can be applied to automotive parts.

Examples of processes, applications and thermoplastic parts welded using hot plate, infrared, laser, ultrasonic and spin technologies : dashboard, headlights, dashboard elements, tank, airbag, filtration elements, SCR (selective catalytic reduction), intake manifold, etc.

In ultrasonic cutting technology : finishing of composite parts, ultrasonic cutting of dashboard elements, foam and lining elements, ultrasonic cutting of complex materials and rubber (tyre type), etc.
