  • What is LSR moulding, and how does it differ from traditional rubber moulding?

    LSR moulding involves injecting liquid silicone rubber into a mould. It differs from traditional rubber moulding because LSR is highly resistant to heat, chemicals, and sterilisation processes, making it ideal for medical and high-performance applications.


  • What are the advantages of using LSR?

    LSR offers an excellent compression set, elasticity, high-temperature resistance, and biocompatibility, which makes it suitable for applications in medical devices, automotive components, and consumer products.

  • Can you create LSR mouldings for medical applications?

    Yes, we work with FDA/USP Class 6 approved materials to produce medical-grade components suitable for autoclave sterilisation and other stringent requirements.

  • What is the typical lead time for LSR moulding projects?

    Lead times can vary based on project complexity and volume, but our in-house toolroom allows us to quickly respond to enquiries and minimise turnaround times.

  • Do you offer LSR over-moulding?

    Yes, we specialise in LSR over-moulding, combining liquid silicone rubber with other materials to create multi-material components with enhanced functionality.
