Life Science / Medical Injection Molding

Medical LSR Products

Medical, healthcare and life science companies have high expectations – parts must adhere to increasingly tight tolerances and meet cleanliness requirements. Compared to other materials and processes, medical grade LSR coupled with SIMTEC’s advanced molding technology, class 8 clean room, and highly automated LSR/LSR 2-Shot / Multi-shot manufacturing provide greater clarity, chemical resistance, purity, and value for high precision silicone components.

LSR & Environmentally-Controlled Manufacturing

Liquid Silicone Rubber (LSR) is naturally inert, resistant to many substances, and bio-compatible, making it an ideal choice for a wide range of medical and healthcare devices, mother and child care products, sanitary and others with hygienic requirements.  For some medical and healthcare products, hygiene is critical and requires production in a hygienic, environmentally controlled environment.  To meet these needs, SIMTEC Silicone Parts offers LSR and LSR Multi-Shot molding in its ISO-certified Class 8 Clean Room.
For specific, information about LSR’s suitability for medical device injection molding, we recommend visiting our technical information page or contacting us directly.

Respiratory Devices

Unlike many natural rubber/latex products, Liquid Silicone Rubber’s molecular structure is composed of an inorganic backbone, and it is naturally stable, hypoallergenic and bio-compatible, which makes it an ideal material for silicone medical devices with skin contact applications, such as respirator masks and other respiratory devices.

Fluid Management

High precision LSR medical device injection molding enables the manufacturing of perfectly uniform components directly out of the machine. The flexibility of the material is ideal for valves, diaphragms, and other silicone medical products which need to yield under pressure but fully close when pressure is released. Because LSR is inert and has superior physical properties it is also perfectly suited for components that come into contact with chemicals, blood, and bodily fluids such as connectors, seals, gaskets, and impellers used in dialysis filters and infusion pumps.

Syringe Parts

Using the right design and LSR material for syringe stoppers and plugs ensure optimal sealing pressure and friction. LSR’s low compression set and superior strength make the material perfect for silicone medical products, such as syringe stoppers. Our automated, high-precision injection molding technology ensures consistent, repeatable, high-quality parts. In-line assembly or direct over-molding can add value for syringe stopper applications by reducing or eliminating assembly costs and errors.

Multi-Component Metal/Plastic to LSR Parts

Multi-component molding offers the benefits of improved part quality and consistency. Complicated assemblies can be eliminated by direct mechanical and chemical bonding of LSR onto plastics or metal, thereby reducing assembly time and costs. Over-molding LSR onto surgical tool handles provides added grip strength for increased accuracy and comfort, while at the same time providing a surface that can be sterilized or auto-claved. Multi-component valves, washers, and seals also benefit from LSR’s material properties and the reduced assembly steps of LSR 2-Shot medical device injection molding or over-molding.

Device Components

Liquid Silicone Rubber is ideal for medical injection molded components, such as tubing connectors. The main characteristics of LSR that benefit this type of application include high purity, transparency, flexibility, and inertness.
