While operating independently, we will continue to work closely with Fischer Söhne AG (injection molding), ensuring customers benefit from specialized expertise and seamless cooperation between both companies.

Muri, 11 June 2025 – From concept development to series production, Fischer Söhne Extrusion AG is your reliable partner for customized plastics solutions – all from a single source. Our strength lies in combining technical expertise with state-of-the-art manufacturing technologies to deliver tailor-made solutions for the chemical, food, pharmaceutical, medical, industrial, and packaging sectors.

Development: Smart Solutions Start with Smart Engineering

Innovation starts in our Development department, where we create customer-specific solutions in close cooperation with our clients. From the initial concept to series production, our engineers apply their extensive expertise in:

• Product development and design
• Prototyping and validation
• In-house mould construction and toolmaking

This integrated approach ensures rapid implementation, flexible adaptation, and efficient production processes. Our focus: functional design, reliable manufacturability, and compliance with all industry standards.

Our in-house toolmaking enables maximum flexibility and ensures that your product reaches the market quickly and efficiently.

Production Excellence: Certified Quality

At Fischer Söhne Extrusion AG, quality begins with extrusion blow moulding. With 10 machines in operation, we specialize in manufacturing high-quality hollow containers, primarily using HDPE. This process ensures precise wall thickness, low material consumption, and cost-efficient production for both small and large series.

In close collaboration with Fischer Söhne AG, we also offer integrated solutions that combine extrusion blow moulding with injection moulding technologies. This in-house cooperation enables us to deliver durable, tailor-made plastics solutions – from simple containers to complex medical components – all from a single source.

Our production processes are certified according to ISO 9001 and BRC Global Standard, ensuring maximum safety and hygiene. To guarantee precision, we rely on tactile and optical 3D measuring machines, while specialized analyses such as CT scans are performed in cooperation with expert partners. Continuous monitoring and systematic Failure Mode and Effects Analysis (FMEA) underpin our sustainable quality management.

Assembly: Efficient Integration and Automated Packaging

In our Assembly department, we combine individual parts into subassemblies or finished products – from simple containers to complex multi-component solutions. Depending on project requirements, we apply manual assembly, inline assembly, or fully automated packaging systems in the cleanroom, ensuring maximum efficiency and hygiene in the final packaging process.

Thanks to our flexible infrastructure and many years of experience, we produce assemblies efficiently and reliably, tailored precisely to customer needs. Our centralized logistics, optimized warehouse capacities, and silo storage for bulk materials ensure a smooth material flow and flexible delivery options adapted to your supply chain.

By collaborating closely with our clients, Fischer Söhne Extrusion AG develops custom solutions from concept to delivery – always from a single source.

With the installation of our new solar system, we are sending out a clear signal of our responsibility towards the environment and the future. Around 1000 solar modules on an area of almost 2,000 m² – this is not only impressive, but also an important contribution to energy efficiency. With an output of around 440 kWp, this system sets new standards for us.

This project is a strong example of the implementation of our new strategy and our brand image, which focuses on innovation, sustainability and progress. A big thank you to Energie Freiamt and everyone involved for the excellent collaboration – together we are shaping a sustainable future!

Fischer Söhne AG, the Swiss plastics specialist with over 100 years of experience, is presenting itself with a new brand identity. The rebranding underlines the consistent focus on the future-oriented life science market and positions the company for further growth, in addition to its established business with plastic packaging solutions.

“The secret lies in the courage to tackle challenges, in the ability to learn and develop further,” says Iwan Tresch, CEO of Fischer Söhne AG.

As part of the brand rebranding, the brand positioning was sharpened and a new logo and claim were developed. All communication documents were revised. The key element of the new image is the modern and informative website.
