Sonplas GmbH

Sonplas is a German company that builds special purpose machines. These include assembly and testing systems and complete production lines. The company says it has done this for more than 30 years. The site does not state its town, but it gives a phone number in Germany. Aviation is one of several sectors it serves.

Sonplas works in mobility and energy, medical technology, aerospace and defense, consumer goods and power tools, and test bench design. In mobility the focus is on fuels and media, rotors and power electronics. The site says the company has been a partner to aerospace and defense customers for over 10 years, in work that needs high precision and process safety.

The company says it serves OEMs and Tier 1 suppliers, mid sized companies, research institutes and start ups. It has its own research and development team. Projects can run from product development and feasibility studies to series production. Systems range from small modular units to large installations worth up to 15 million euros.

Sonplas has also developed its own processes. The HERO process, short for HydroEROsive Machining, uses an abrasive fluid to deburr, round and size inner and outer shapes. The patented process is listed on the site. The company also does laser cutting, such as notching, slitting and singulation.

Its machines and teams work at several sites in many countries, and the home page shows three plants in Germany with solar panels on the roofs. The site has a careers page for job seekers and links to Facebook, Instagram, LinkedIn and YouTube.
