Nanjing Lsan Co., Ltd.—silicone expertise built for custom manufacturing
Nanjing Lsan Co., Ltd. (LSAN) is a Nanjing-based manufacturer specializing in the research, development, production and sales of rubber and silicone rubber products. With more than 30 years of industry experience, we supply silicone sheets and application-specific components to OEMs and industrial customers worldwide.
Our 5,000 m² facility brings together laboratories, testing rooms, material-mixing areas and standardized production workshops, supported by a team of 56 professionals. This integrated setup helps us coordinate material development, tooling, molding, extrusion, die-cutting and inspection around the needs of each project.
Today, our focus is custom silicone parts for sectors where performance matters—medical, aerospace, defense and robotics—while continuing to support customers requiring silicone sheets, gaskets, seals, diaphragms, bellows, plugs, caps, profiles and bonded components.
- 2D/3D drawing and sample review
- Material and process guidance
- Prototype-to-production support
- Clear export communication
Precision with purpose
Make demanding silicone projects manufacturable and dependable.
We turn technical requirements into practical components through clear engineering communication, disciplined production and consistent quality—so every part can perform with confidence in its intended application.
Be the trusted silicone manufacturing partner behind safer, smarter systems.
We aim to support teams building safer medical devices, lighter aerospace systems, resilient defense equipment and more capable robots through long-term, technically grounded collaboration.
Four sectors where material performance matters
Each market brings different demands for cleanliness, temperature, sealing, vibration, durability and traceability. We align the solution to the actual project specification.
Medical & Healthcare
Custom seals, diaphragms, protective parts and fluid-interface components developed around device geometry, cleanliness and documented material requirements.
Aerospace & Aviation
Lightweight sealing, vibration-isolation and environmental-protection components for assemblies exposed to temperature cycling, motion and demanding operating conditions.
Defense & Security Systems
Rugged boots, covers, seals and protective silicone parts developed to controlled drawings for harsh environments, field equipment and specialized assemblies.
Robotics & Automation
Flexible bellows, gripper interfaces, cable protection, seals and damping components that support repetitive movement and reliable machine performance.
A controlled route from requirement to production
Custom projects move faster when technical decisions are clear. We establish the specification, manufacturing route and inspection points before production begins.
Requirement Review
We review drawings, samples, dimensions, operating temperature, media, hardness, color, quantity and documentation needs.
Material & Process Selection
A practical compound and process are proposed for the geometry, performance target and expected production volume.
Tooling & Sample Validation
Key dimensions and functional features are confirmed through tooling review and samples when project validation is required.
Production & Inspection
Material, appearance and agreed critical dimensions are checked before packing, shipment and repeat-order support.
Reliable parts begin with reliable communication
We judge our work by whether engineering teams can validate, install and reorder with confidence. That requires clarity before tooling and consistency after approval.
Specification before assumption
Materials, dimensions, interfaces and inspection points are aligned before production starts.
Respect for sensitive project information
Drawings, samples and application details are handled as project-specific manufacturing information.
Clear next steps for global teams
Questions, revisions and production updates are communicated concisely and actionably.
Repeatable quality after approval
Agreed requirements stay central from first article review through recurring production.
