# Custom Medical Grade Liquid Silicone Rubber Parts
Custom Medical Grade Liquid Silicone Rubber (LSR) Parts are precision-engineered elastomer components manufactured to meet the strict regulatory and performance requirements of the medical and healthcare industries. Unlike off-the-shelf rubber products, our custom LSR parts are tailored to your exact design specifications, material requirements, and end-use functional needs, enabling seamless integration into complex medical devices, diagnostic equipment, and patient care applications.
Our custom LSR manufacturing process combines high-precision liquid injection molding (LIM) with rigorous material traceability, producing parts that exhibit exceptional biocompatibility, thermal stability, chemical resistance, and elastic recovery. We support projects from low-volume prototyping to high-volume mass production, with full design assistance to optimize part performance and manufacturability without compromising compliance with global medical industry standards. Whether you need a single complex prototype or millions of production-grade components, our custom LSR solutions deliver consistent quality and performance that medical device manufacturers rely on.
All custom LSR parts are produced from 100% pure platinum-cured liquid silicone rubber, free of organic peroxides, phthalates, BPA, and other toxic additives common in conventional rubber products. Key material properties include:
Physical performance parameters can be adjusted per application requirements, with standard ranges as follows:
All physical properties are tested and validated per batch to ensure consistency with your project requirements.
Our custom LSR parts are produced via precision liquid injection molding (LIM), with controlled process parameters to ensure dimensional accuracy and material consistency:
Our custom LSR materials are sourced from ISO 13485-certified raw material suppliers, with full traceability from resin batch to finished part. All materials meet US FDA 21 CFR Part 177.2600 requirements for food and medical contact, and are tested for cytotoxicity, irritation, and sensitization per ISO 10993 standards. This eliminates compliance risks for your medical device submissions to the FDA, CE, and other global regulatory bodies.
Liquid injection molding of LSR enables production of extremely complex geometries, thin walls, undercuts, and overmolded assemblies that are not possible with conventional compression molded silicone. We support overmolding onto rigid substrates including PC, ABS, PEEK, stainless steel, and titanium, creating fully integrated multi-material components that reduce assembly costs and improve device reliability.
Platinum-cured LSR is non-toxic, non-irritating, and non-sensitizing to human tissue, making it ideal for long-term and short-term body contact applications. Unlike peroxide-cured silicone, our LSR contains no residual byproducts from curing, eliminating the risk of leachable contaminants that can cause adverse patient reactions. The material is also naturally hypoallergenic, making it suitable for sensitive skin applications.
Custom LSR parts retain their elastic properties, tensile strength, and dimensional stability after repeated sterilization cycles, with no cracking, brittling, or degradation over the product lifecycle. The material is resistant to lipid absorption from body fluids, preventing swelling or performance loss in long-term implantable or chronic care applications.
Custom medical grade LSR parts are used across a wide range of medical and healthcare applications, including:
Choose LSR hardness based on your application's functional requirements:
We accommodate all part sizes within our manufacturing capabilities:
Select the appropriate material grade based on your application's exposure requirements:
We maintain a fully ISO 13485:2016 certified quality management system for all custom medical LSR part production, with end-to-end quality control at every stage of manufacturing:
Our quality team works closely with your engineering and regulatory teams to ensure all custom parts meet your specifications and support successful regulatory approval of your medical device.
