Custom LSR injection molding and medical silicone component manufacturing, supported by ISO 13485 quality management, ISO Class 8 cleanroom production, and in-house engineering and tooling.
LSR Injection is an ISO 13485-certified medical silicone manufacturer specializing in custom LSR injection molding and precision components.
With an ISO Class 8 cleanroom, in-house tooling and engineering, we support Class I & II medical device projects from prototyping to production.
OUR PRODUCTS
Explore our medical and specialty silicone product categories, including custom molded components, CPAP parts and medical tubing. OEM/ODM support from tooling to production.
MEDICAL SILICONE DEVELOPMENT
We work with medical device teams on design review, material selection, custom tooling and production. Our engineers consider manufacturability and project requirements from the start.

Review geometry, material options and manufacturing feasibility.
Develop precision tooling around critical component features.
Evaluate samples against agreed functional requirements.
Transition to repeat production with defined inspection criteria.
WHY LSR INJECTION
Our focus is on practical engineering support, consistent production and the quality controls medical device teams expect from a manufacturing partner.
Documented quality management practices to support controlled manufacturing and customer requirements.
A controlled environment available for medical silicone projects that require cleanroom production.
Tooling design and manufacturing support for complex features, fit and surface requirements.
Injection molding, compression molding and extrusion options selected for the component design.
DFM input, material selection and prototype reviews before the production tool is finalized.
Inspection criteria and production records aligned with the approved project scope.
CUSTOM MANUFACTURING
We coordinate the steps that turn a medical silicone component design into a repeatable, production-ready part.
CAD review, DFM input and early material and process evaluation.
Mold development and design adjustments to meet agreed requirements.
Post-curing, trimming, assembly, marking and packaging as specified.
Sampling, repeat production and inspection with clear project communication.
Available processes and documents depend on the component, agreed manufacturing scope and intended medical application.
PROCESS SELECTION
Part design, material grade, volume and functional requirements determine which molding method fits the project.
For intricate geometries and repeat production of precision silicone components.
A useful option for selected HCR materials, geometries and production requirements.
For continuous tubing and profiles requiring defined dimensions and material properties.
Send us a drawing or a brief description of your project. We can discuss material, tooling and manufacturing options.
QUALITY & PRODUCTION CONTROL
ISO 13485 quality management, ISO Class 8 cleanroom capability and defined inspection processes support our medical silicone manufacturing projects.

CONTROLLED MANUFACTURING
Our ISO Class 8 cleanroom provides a controlled environment for medical silicone parts requiring defined cleanliness conditions. Production procedures and inspection criteria are reviewed according to each project’s needs.
Quality documentation and project-specific testing requirements are confirmed during supplier qualification.
Documented procedures support controlled production and quality oversight.
Defined dimensional, visual and functional checks support consistency.
Relevant material identification and production records are managed by project scope.
DESIGN CONSIDERATIONS
Medical silicone part performance starts with product requirements and thoughtful decisions made before tooling.
Select LSR or HCR formulations against contact conditions, hardness, mechanical performance and documentation needs.
Review wall thickness, critical fit features, parting lines and achievable tolerances during DFM.
Plan tooling details, visual expectations and inspection criteria before the component enters repeat production.
