Liquid Silicone Rubber Molded Parts

Meeting customer needs with precise, high-quality components

Liquid Silicone Rubber (LSR) molded parts offer a virtually unlimited range of design. These are produced as a single part and can be manufactured in high volumes.

Advantages of LSR molded parts:

  • Limitless design – Enables production of part geometries and technical solutions not possible otherwise
  • Consistent – Provides the highest consistency in product dimension, precision and overall quality due to lean manufacturing processes
  • Pure – Silicone is one of the most extensively tested biomaterials with a long history of safe use
  • Precise – Flashless, wasteless tool design concepts for parts from 0.002 grams to several hundred grams in weight
  • Reliable – Using latest technology in machinery, tooling and automation
  • Quality – ‘0’ Defect Quality Level through in-process controls
  • Fast – Enables highest volume production as a result of short cycle times; from several thousand to millions
  • Clean – Utilizing state-of-the-art processing techniques and production in Class 7 and 8 cleanrooms
  • Cost-effective – Offers lowest Total Cost of Ownership (TCO) for the customer

Our LSR components are the result of your and our designers’ imagination plus the quest for innovative solutions of our toolmakers and process engineers. LSR experts partner with customers using a holistic approach based on customers’ specifications and requirements.

Application Examples – LSR Molded Parts

Breast Shields

Perfect flash-free molding is essential in some of the parts produced in Liquid Silicone Rubber (LSR) such as nipple protectors produced for nursing mothers.

Automation meets super clean requirements

The nipple protector is produced in a cleanroom to prevent its high gloss finish being blemished by airborne particles such as dust. The part cannot be manually handled, as the slightest fingerprint would spoil its crystal clear finish. Therefore the nipple protector is removed robotically from the tool and placed on a belt feeder that takes the product through post-cure and straight into the box it is shipped in.

Timings between all process steps are perfectly aligned to have a continuous process flow. The part must be flash-less, as any flash at the nipple shield hole would prevent effective milk delivery from a nursing mother.
