Liquid Silicone Rubber (LSR) can be processed in a liquid injection molding (LIM) process. The liquid raw material is mixed from two separate components in a ratio of 1:1 and injected via a cold-runner-system into a hot mold. Curing of the parts in the mold takes place within seconds, therefore offering the advantage of fast cycling and production of large quantities quickly.
Due to the flexibility in design and tooling, LSR injection molding is ideal for the production of complex geometries and can consolidate various functional features into a single part. LIM offers significant advantages in terms of product reliability and total cost of ownership.
Healthcare & Medical Applications
LSR injection molding is an ideal production method for a range of medical products. Applications range from drug delivery such as primary drug packaging or wearable smart drug pump systems, fluid management, diagnostics, to biotechnology.
Aiming for the highest quality LSR components, Trelleborg Healthcare & Medical injection molding experts partner with customers and take a holistic approach to the engineering of component, tooling and overall process to take advantage of the full capabilities that highly viscous, fast-curing silicone offers. Whether made-to-print or beginning with a black box design, high precision in-house LSR tool making and optimum process automation are the foundation of high precision, high quality components that provide the lowest cost of ownership for the customer.
