Manufacturing Solutions for Healthcare & Medical
Advanced Automation

Our fully automated manufacturing process aims to provide customers with high quality, pure and cost effective solutions. We combine expertise in tool design and process engineering with the highest levels of process automation, in particular for:
- Liquid Silicone Injection Molding (LIM)
- Two Component Injection Molding
Our fully automated LSR and LIM processing provides all the advantages needed for success in the healthcare and medical industry:
- Purity – a closed loop system ensures that no external impurities can be introduced through either the process or human contact
- Precision – flashless, wasteless tool design concepts ensure high precision and quality
- Quality – quality is controlled in the process, not through extra control steps
- Reliability – automation guarantees repeatability and reliability of process across millions of parts produced every year
- Cleanliness – closed loop manufacturing set-ups in Class 7 and 8 cleanrooms guarantee the highest level of cleanliness
- Cost Effectiveness – Lowest Total Cost of Ownership (TCO)
Cleanroom Production

Components for the medical, pharmaceutical, healthcare and medical industries require the highest levels of cleanliness at all steps of production to meet stringent hygienic standards. The need for germ- and contaminant-free components and environments is ever increasing. And, as parts become smaller, they are more sensitive to airborne particles, even those found normally in the air.
Trelleborg Healthcare & Medical manufacturing facilities are equipped with high-tech cleanrooms to support customers when medical applications require ultra-clean products. Our cleanrooms conform to ISO 14644-1 and meet stringent internal technical and operating standards in order to guarantee the highest level of quality, cleanliness, hygiene and process control.
Key benefits:
- Produced in a Class 100,000 (ISO 8) environment
- Washed with integrated high-purity water preparation system in a Class 10,000 (ISO 7) environment
- Double-bagged in a Class 10,000 (ISO 7) environment
- Capable of handling lots from several thousand up to millions of pieces / meter of tubings
- Site certifications to ISO 9001, ISO 14001 and ISO 13485
Our tubing and hose is primarily manufactured in a controlled environment to class 100,000 conditions. We regularly monitor ambient temperature, humidity and particulate counts, as standard.
Special requirements
In addition to standard cleanroom operations, Trelleborg Sealing Solutions offers a wide range of special finishing operations and services such as:
- Special washes, such as acetone washes
- Product coatings and surface modification
- Product sterilization
- Special customized packaging
- Reduction or elimination of secondary operation, such as:
- Assembly
- Cutting-to-length
- Overmolding
Precision LSR Tooling

Building molds for liquid silicone rubber processing requires high precision. Due to the low viscosity of LSR, it is challenging to prevent flash in the tiniest of gaps. Simultaneously, product designs are increasing in complexity. LSR molds require a high level of engineering, machining and processing precision.
The Trelleborg Healthcare & Medical automated approach to LSR processing is unique. From stage one, tooling design is developed to:
- Optimize the function of a component in the application
- Maximize the effectiveness of automated operations
Flash-less part and tool design, waste-less process, in-process quality checks, batching by cavity and packaging are considerations that are always made.
