Swiss Roots. International Manufacturing Strength.

Hemargroup is built on Swiss engineering culture: precision, responsibility, reliability, and long-term technical partnership.

While our U.S. manufacturing presence brings production closer to American customers, the foundation of the group remains deeply connected to Swiss industrial experience, European quality standards, and decades of electronics manufacturing expertise.

The group brings together several specialized entities, each contributing to the engineering, production, and service strength behind Hemargroup.

Hemar AG

The core Swiss EMS and engineering foundation of the group, bringing electronics manufacturing expertise, quality discipline, and long-standing industrial experience.

SEFA SA

A production and service partner within the group, supporting customers with practical manufacturing knowledge, technical execution, and dependable industrial processes.

HSCS Sagl

A specialized support entity that strengthens the group’s wider technical, operational, and service capabilities.

Together, Hemar AG, SEFA SA, and HSCS Sagl give Hemargroup a strong Swiss foundation — supported by expanding international manufacturing capacity and a shared commitment to quality.

Success Stories

Medical Device Startup — From Prototype to Success medical startup

A healthcare startup approached us with a promising prototype that wasn’t ready for scaling.

We re-engineered the design, optimized the electronics, introduced new QA processes, and set up reliable production.

Results:
  • Market-ready device within 6 months
  • Stable production
  • Long-term client relationship
Circuit boards

HVAC Manufacturer — Reducing Failure Rates HVAC Manufacturer

An HVAC company faced recurring electronics failures affecting service contracts.

Hemar optimized the PCB design and introduced deeper traceability and process controls.

Results:
  • 67% fewer failures
  • Faster servicing
  • Better customer satisfaction

Municipal Safety System — Human Impact municipal project

A municipality needed a smart system to protect children crossing roads during school hours.

We delivered robust electronics that improved timing, monitoring, and safety.

Results:
  • Safer school zones
  • Positive feedback from parents
  • Scalable solution for future cities
