About elfo ag

Our company is based in Sachseln in the geographical centre of Switzerland. We have over 45 years of experience as an industrial supplier in various industries.

As an industrialisation partner we focus on parts manufacturing as well as tool and mould making.


History of elfo ag


The company name elfo ag is derived from “electroforming”. We started with the galvanic production of foils using the electroforming process and then insertmoulding with plastic.

This is where our decades of experience with insertmoulding and overmoulding filter material and precision injection moulding comes from.


In the meantime we have continued to develop. We offer a holistic service from the initial design idea to the fully developed product.

Our core competence is the industrialisation and production of filters, strainers, high-performance plastic parts, precision injection moulded parts and water filters.


The company elfo ag is committed as a company in various areas.

As part of our apprenticeship training, we provide the next generation and support the Swiss dual education system. The training and further education of employees is an important pillar in our personnel philosophy.

We actively promote the health of our employees with an internal health management system.

We support local organisations and associations through selected sponsoring contributions.

Our staff benefit from selected fringe benefits.

Spontaneous applications are welcome.
