starlim is the world’s largest manufacturer of liquid silicone products and, as a full-service provider, can take care of all tasks required for your development and production orders. This saves you valuable time and resources.
In the car, in the baby pacifier, in the kitchen drawer – these are just a few examples of places where starlim products can be seen or even installed unseen. The ubiquity of starlim’s products is the result of our specialization in the injection molding production of small parts made of silicone in single and multi-component technology. Our clear focus is mass production.
As an international group of companies, we produce over 14 billion silicone parts annually, mainly for the manufacturing industry, the life sciences and the mobility sector. But since we make a point of doing everything to make the wishes and ideas of our customers become a reality, we are also happy to manufacture your exclusive silicone parts for any other sector. No matter how big the challenge, together we will achieve the best possible result.
Do you have a vision for a new product in mind, but still haven’t found a way to make it a reality? Or do you already know the geometry your product should have but still need help in choosing the right material? No problem! As a full-service provider, we, together with our partner, the tool building company sterner, take care of the entire production chain from the idea to the finished product.
What does starlim do?
starlim is a manufacturer of precision molded parts made of liquid silicone rubber (LSR) and specializes in automated mass production of large quantities. The company develops and produces complex silicone components using injection molding for industry sectors such as life sciences, mobility, and manufacturing.
What is starlim’s area of specialization?
starlim specializes in the development and highly automated mass production of components made from liquid silicone rubber (LSR).
The company produces complex silicone components in high volumes, combining extensive expertise in materials engineering, toolmaking, automation, and injection molding technology. Particularly for demanding applications with high quality requirements, starlim helps customers bring innovative silicone solutions into series production in a cost-effective and reliable manner.
What is Liquid Silicone Rubber (LSR)?
Liquid Silicone Rubber (LSR), also known as liquid silicone, is a liquid, cross-linking silicone material that is processed using injection molding. It is primarily used in mass production when precise, flexible, and durable components are required, such as in medical technology, the automotive industry, or industrial applications. For more information on silicone as a material, click here.
What are the advantages of silicone over other materials?
Silicone offers significant advantages over many other materials: It is heat-resistant, elastic, and consistently stable when exposed to chemical and environmental influences. Compared to thermoplastics, liquid silicone rubber (LSR) is particularly well-suited for applications that require sealing, flexibility, and a long service life under demanding conditions.
Which industry sectors does starlim manufacture products for?
starlim manufactures silicone components for industry sectors such as life sciences (including medical technology), mobility (including the automotive sector), and industry (including consumer applications). The requirements vary significantly depending on the application—ranging from highly regulated applications in medical technology to durable and functional components in the automotive and industrial sectors. Typical applications include, for example, seals, membranes, or complex functional components that must be precise, elastic, and capable of withstanding long-term stress.
What is the minimum order quantity at which LSR becomes cost-effective?
The cost-effectiveness of silicone injection-molded parts depends heavily on factors such as part geometry, size, complexity, and quality and tolerance requirements. Generally speaking, LSR really shines with medium to high production volumes, as automated manufacturing processes enable efficient and consistently high-quality mass production.
At the same time, starlim supports customers early in the project phases, taking planned scalability into account. Components can be designed so that they can initially be produced in smaller quantities and later efficiently transitioned to high-volume production.
Which production and automation technologies does starlim use?
starlim relies on highly automated manufacturing systems for LSR injection molding, in which production, demolding, and quality control are fully integrated. This enables even complex components to be produced in large quantities with consistent results, using both single- and multi-component injection molding processes. A key focus is on the targeted design of stable processes. Using simulations, process data, and experience from existing series production projects, manufacturing parameters are defined to ensure consistently high quality throughout the entire production cycle.

Does starlim provide a cleanroom manufacturing service?
Yes, starlim operates cleanroom production facilities for applications with particularly stringent requirements, such as in medical technology and the life sciences sector. Manufacturing takes place in a controlled cleanroom environment compliant with ISO 14644-1 Classes 7 and 8, as well as GMP Classes C and D, to reliably meet defined requirements for particle and microbial contamination. Cleanroom production covers the entire manufacturing process—from injection molding through curing and washing to the packaging of silicone and multi-component parts. This ensures that the parts are manufactured under consistently controlled conditions and are ready for demanding applications.
Does starlim offer support for product development?
Yes, starlim provides comprehensive support to customers in the development of silicone components—from the initial idea through to stable mass production.
The focus is on designing components early in the project to ensure they can be manufactured in a way that is functional, cost-effective, and process-reliable. To achieve this, starlim combines in-depth material and process expertise with comprehensive development services. These range from structural design and material- and manufacturing-oriented design to the use of simulations that allow for early evaluation of component behavior and future mass-production suitability. This is complemented by extensive testing and analysis in the development laboratory, as well as data-driven insights from numerous mass-production projects. On this basis, even complex geometries can be specifically optimized and reliably transitioned to stable high-volume production.
How does the collaboration with starlim work?
Collaboration with starlim is structured flexibly and tailored to the status of each project. Customers can join at various stages—from the initial idea through existing designs to specific requirements for mass production.
Depending on the initial situation, starlim takes on the appropriate tasks throughout the entire development and production process. These range from requirements definition and component development, through simulations and tooling, to industrialization, mass production, and subsequent post-processing or logistics.
Thanks to this flexible structure, projects can be implemented efficiently and specifically geared toward stable and cost-effective mass production—regardless of where the collaboration begins.
How does starlim ensure quality and process reliability?
starlim ensures quality through an integrated, cross-functional management system that encompasses quality, the environment, safety, and energy. This system is firmly embedded in all processes and is continuously refined to ensure consistently high product quality. A central component is starlim’s zero-error philosophy. The goal is to design and control processes in such a way that defects are prevented in advance—from development through tooling to series production. These high quality standards are confirmed by internationally recognized certifications, including ISO 9001, IATF 16949 (automotive), ISO 13485 (medical technology), as well as ISO 14001 and ISO 45001 for environmental and occupational health and safety management.
Through a combination of standardized management systems, data-driven processes, and extensive experience from mass-production projects, starlim ensures that even complex silicone components can be manufactured in large quantities with consistent quality and process reliability.
