Sirius Electric is an Italian company based in Vigevano (Lombardy), operating in the plastic welding sector since 1989.
We manufacture and sell ultrasound welding machines, hot plate welders, vibration welders and spin welders. By means of different welding techniques, we are able to face challenges related to the assembly of thermoplastic parts. We also deal with the design and production of sonotrodes. Here, we manage to verify future operations thanks to the use of top level simulation software systems.


Our starting point is a thirty-year experience in the plastic welding industry. We design, produce and test internally, through the help of  top quality materials and parts, cutting-edge CNC machines and 3D CAD systems. We believe in our clients’ central role and needs. For this reason, supporting and assistance stages – both before and after sales – together with the direct contact with the technical department play a key role. This process allows us to design and develop co-created and tailor-made projects. The collaborative structure makes us achieve two essential goals: fast problem-solving and positive feedback of our clients.


We believe in innovation, in all its shapes and forms. This is why we keep an eye on new process and application investments, besides preparing our machinaries according to Industry 4.0 principles. We constantly commit ourselves to find new technical solutions to make our work and our clients’ even more efficient.
