Frey & Winkler stands for precision, material expertise and reliable processes – from the initial concept through to series production. Our focus lies on liquid silicone rubber injection moulding (LSR) and the manufacture of filigree precision injection-moulded components, complemented by thermoplastic processing, metal and hybrid solutions, as well as multi-component technologies.
Whether it is two-shot injection moulding for functional material combinations or the right toolmaking expertise for reproducible quality, we consistently support the design process of our customers with manufacturability in mind. This results in components that deliver convincing performance, durability and cost-effectiveness in use, particularly in demanding sectors such as medical technology or eyewear components, where details, tolerances and process reliability are crucial.
Many projects do not begin with a finished drawing, but with a goal: less installation space, more functionality, improved haptics, greater sealing performance or a more robust solution. We support you right from the start – from aligning requirements and selecting materials such as LSR and thermoplastics through to design for manufacturing. Together, we assess feasibility, tolerances and process windows and systematically turn ideas or early samples into series-ready products. This ensures functional reliability, quality and cost-efficiency remain in balance at every stage.
At Frey & Winkler, you receive every step from a single source: from planning and design support to toolmaking, prototypes and series production. We manage the entire process throughout, reducing interfaces and coordination effort. On request, we also provide additional services such as assembly, customised retail-ready individual packaging or labelling, allowing you to deliver directly. This makes projects faster to manage and ensures stable processes across the entire supply chain.
We work according to the “one face to the customer” principle: you have one dedicated, technically experienced contact partner who knows your project, sets priorities and guides implementation reliably. Clear and direct communication, short decision-making paths and defined process steps ensure that decisions are made quickly, from the initial quotation through to ongoing series production. This creates commitment to deadlines, transparency in project status and reliable implementation, even when changes arise. Your project remains predictable and is driven forward consistently.

Our production is designed for precision and scalability – for small series just as much as for very large order quantities. A demand-oriented degree of automation, a broad machine portfolio and structured process management provide the basis for reproducible results. Depending on the component, tolerance requirements and production volume, we select the right manufacturing strategy and ensure consistently high component quality. This allows us to deliver cost-effectively, on time and reliably, even for demanding precision components.
At Frey & Winkler, quality is not a promise, but a way of working: we manage projects so that precision and process reliability are safeguarded at every stage, not only during final inspection. With DIN ISO 13485 and DIN ISO 9001, we meet defined standards that provide a reliable basis for quality and safety, especially for components used in medical devices.
To ensure results remain reproducible, our quality management is closely integrated into day-to-day operations. Even during quotation and project launch, we rely on error-prevention measures, clear responsibilities and standardised project management in accordance with APQP, including advanced quality planning. In ongoing series production, we safeguard stability through defined process and production monitoring. This creates robust data, minimises deviations and ensures repeatable accuracy, even for filigree precision components and complex material combinations.
At Frey & Winkler, we see ESG as both an obligation and a commitment to managing our company in a future-proof way. For us, responsibility means considering environmental and social aspects just as consistently as economic goals. This creates stability for our employees, our customers and our supply chains.
In day-to-day business, this is reflected in clear priorities: we focus on more efficient use of resources, work on reducing CO₂ emissions along relevant processes and promote a culture in which safety, respect and reliability are a matter of course. Transparency is key in this context. Our ESG documents bring together our Code of Conduct, company guidelines, as well as ratings and reporting on our ESG performance.
Promolding BV, Frey & Winkler International GmbH and P3D (Promolding 3D Printing BV) combine their expertise, thereby expanding their joint service portfolio for medical applications and precision components. This partnership brings together know-how in high-performance polymers, injection moulding and cleanroom environments with 3D-printed tooling concepts. As a result, projects can be transferred more quickly from the first sample to validated series production, including validation and scaling up to larger quantities. The focus is on components that meet strict requirements in terms of sterility, safety and functionality, while also being manufactured efficiently and with careful use of resources.
Our current focus lies on expanding the production of injection-moulded parts made from liquid silicone (LSR) and 2K components. Although much has changed over the course of the company’s history, one thing remains at the centre of Frey & Winkler’s philosophy to this day: product quality. A key element in achieving this is our in-house toolmaking, which we have always regarded as essential for precision and reliability. Customers and new partners alike can rely on us to uphold this commitment to quality consistently.
When it became clear that the labour-intensive eyewear industry was increasingly relocating to low-wage countries, Frey & Winkler began early to develop additional sectors and automation. Today, alongside medical technology and the optical industry, we also supply other branches of industry with injection-moulded parts made from a variety of materials, with a focus on 1K and 2K silicone parts as well as combinations with plastics and metals.
At that time, one core focus was nose pads for the internationally oriented eyewear industry. While these components were initially made from cellulose acetate and soft PVC, Frey & Winkler switched to industrial production using silicone rubber in 1982. For this application, a specially developed silicone grade with particularly high transparency was used. To this day, the nose pads – which have already been fitted to more than 1 billion pairs of glasses – remain part of our portfolio.
Within ten years, Frey & Winkler had established a name for itself in Germany and across Europe as a supplier of high-quality stamped and embossed parts. At the end of the 1960s, Oswald Frey left the company. In the years that followed, major investments were made and production of injection-moulded components began – a step that significantly accelerated growth and technological development.
Repeated complaints at their former employer provided the starting point: toolmaker Oswald Frey and businessman Emil Winkler decided in 1957 to become self-employed. With roots in the eyewear industry, they pursued one clear goal: to improve quality and reliability consistently. Guided by this mindset and with limited start-up capital, they founded the company that same year – a company that still bears the name Frey & Winkler today.
