Precision Silicone Sleeve Manufacturing
We manufacture custom silicone sleeves to your specifications, with dimensional tolerances of ±0.2 mm. We turn your design into a silicone sleeve that fits and functions in the final assembly.



What a Silicone Sleeve Does
- Ergonomic grip. Improved grip and feel for tools and handles.
- Thermal insulation. Protection for temperature-sensitive components.
- Vibration and noise damping. Reduced mechanical noise and vibration in electronics and machinery.
- Environmental sealing. Protection from dust, moisture, oil, and water.
- Electrical or thermal isolation. Insulation between sensitive parts.
Dimensional accuracy matters. A sleeve that does not fit its assembly fails, so we hold ±0.2 mm and inspect every batch against CAD.
Manufacturing Processes for Sleeve Integrity
High Tolerance LSR Sleeves
For thin walls, complex geometry, and high volume, LSR injection molding runs through our partner. It reproduces intricate designs with high repeatability and tight tolerances.
Compression Molded Robust Sleeves
For robust sleeves with specific material properties or lower volume, compression molding works well. It suits durable parts with inherent strength.
Extruded Continuous Silicone Sleeves
For continuous profiles, such as tubes, cords, and linear sleeves, use extrusion to make profiles with accurate shapes and different wall thicknesses. These products are used to transfer fluids, provide insulation, or protect other components.
In-House Tooling and Prototyping
We machine molds in-house and prototype quickly, so design iterations, precise fits, and cost-effective tooling happen from first concept to scaled production.
Materials for Demanding Sleeve Applications
Grades for Specific Environments
- Biocompatible sleeves for medical devices, to USP Class V and VI and ISO 10993.
- High-temperature and chemical-resistant sleeves for industrial and automotive use.
- Flame-retardant and electrically insulating sleeves for electronics and industrial equipment.
- Food-contact and consumer-safe sleeves to FDA, LFGB, and EN 71-3.
Durometer and Surface
- Durometer (Shore A): 10 to 80, from soft and flexible to firm, set per application.
- Surface treatment: feel-oil coating, anti-dust, and friction control per the sleeve's function.
Engineering and Quality Assurance
Collaborative Design Review
Our engineers review your design with your team and optimize it for manufacturability, performance, Pantone color, and cost.
Testing and Compliance
ISO 9001:2015, ISO 45001:2018, and ISO 14001:2015. We test with ICP-OES, GC-MS, and Proposition 65 checks so every sleeve meets technical and regulatory requirements.
