MACEAS GmbH
New on Amplifa
Leak Testing and Automation from a Single Source
MACEAS GmbH specializes in industrial leak testing and automation. The company develops individual comprehensive solutions for serial production, including helium leak testing, ultrasonic gas bubble detection in water baths, and electrolyte leak testing for battery cells. In addition to constructing customized test systems and special machines, MACEAS offers leak testing services where components can be tested without investing in their own system. Solution development covers clarifying requirements, developing the test concept, designing the serial process with cycle time and component handling, and building and commissioning the system. Covered industries include hydrogen and energy systems, batteries and e-mobility, automotive, HVAC, electronics and sensors, and industrial components and machinery. Since 2025, MACEAS has been a company of GROUP STERLING as MCS STERLING.
