Medical Silicone Sleeve

Medical silicone sleeve also called medical silicone rubber cover, silicone case, silicone rubber bellow, liquid silicone rubber cap, is aimed to protect medical devices from cleaning, purity, and stability, also good at anti-slip, silicone rubber sleeve forms the sealing condition to medical devices, as a cover to care devices surface, similar function to seals but not same exactly.

Medical Silicone Sleeve

Medical silicone sleeve, known as medical silicone rubber cover, medical silicone case, silicone skin case, rubber bellows, sleeve protector, made from biomedical flexible silicone rubber, protects medical devices again dust, water, oil, other solvents, drop, scraps, etc., also as insulation sleeve for health-care devices, which means silicone sleeve creates the sealing function for medical devices, such as silicone sleeve bellow for syringesmedical silicone sleeve

Medical Silicone Sleeve - Compression Molding/Liquid Silicone Compression Molding/Liquid Silicone Injection Molding:

Sleeve expansion bellow cover can be made from solid medical grade silicone rubber, also can choose biomedical liquid silicone material, generally is clear/transparent/high-transparent.

Why Do Medical Syringes Need Silicone Protective Bellow/Cover?

Silicone protective bellow is a kind of protection cover, sleeve or cap, to protect the purity of the medical syringe. Medical syringes are an essential tool for healthcare providers to deliver medications and vaccines to patients safely and effectively. These syringes are carefully designed to maintain the purity of the medication and ensure accurate dosing. The silicone protective bellow/cover is an important component of a medical syringe. Silicone bellow sleeve is made from biomedical silicone material, and completed by compression molding, compression liquid silicone molding, and liquid silicone injection molding (LIM), different silicone syringe bellow cover structures and quality requirements can choose different processing way.

Silicone Bellow Sleeve Serves Several Crucial Functions To Medical Devices:

Medical silicone inflatable bellow can prevent contamination: the flexible joint bellow creates a barrier between the syringe and the outside environment, preventing contamination from dust, bacteria, or other particles, performs the sealing function to medical syringe.

Silicone flexible bellow sleeve can protect the syringe: the cover protects the syringe from damage during transportation and handling, ensuring that it remains ready to use.

Silicone soft bellow sleeve can reduce risk of needlestick injuries: the protective bellow cover is designed to retract over the needle after use, reducing the risk of accidental needlestick injuries for health-care providers.

How To Make Biomedical Silicone Inflatable Expansion Joint Sleeve?

Silicone bellow cover can be made by compression molding, simplified liquid silicone injection molding, and liquid silicone injection molding:

DIY Custom Compression Molding Silicone Sleeve Flexible Bellow for Electronics Both medical grade solid silicone and liquid silicone are available for the compression molding machine, relatively speaking, compression molding liquid silicone bellow sleeve can improve production capacity and make the bellow sleeve parting line be a little smaller than with solid silicone.

Liquid Silicone Compression Molding Medical Bellow Silicone Cover

Compression transfer injection molding can get the good silicone bellow, but the process of silicone material placing takes a lot of time and causes silicone material waste.

For avoiding too many silicone material waste and making the silicone bellow cover be better, change the solid silicone material to liquid silicone, still use the compression mold design or simplified LIM mold, add the liquid silicone feeding system to inject liquid silicone material in mold cavity, this is the liquid silicone compression molding.

Liquid Silicone Injection Molding Medical Silicone Sleeve Protector

More automation high production capacity, the highest safety grade, and the best appearance for biomedical silicone bellow sleeve is made by liquid silicone injection molding. Liquid silicone injection molding is a versatile manufacturing process that has revolutionized the production of medical grade silicone bellow covers and sleeves. These covers and sleeves are highly sought after in the medical industry due to their superior quality and performance.


Medical silicone rubber sleeve is widely used in health-care equipment, devices cables, devices feet, handles, locks, rivets, PCB hardware part, patient care equipment, medical furniture, laboratory equipment, electric vehicle, EV charging, disinfection devices, performed as isolation or combination for medical purposes.

Medical Sleeve Features

Silicone sleeve is a cover or case, made from flexible elastomer high tensile high strength medical silicone rubber, which can be used for many areas and medical devices to snugly wraps around the plastic devices, metal devices, electric devices, wooden devices, etc., to grasp the devices tightly to protect devices.

Surface: small burrs and parting line, even wall thickness, flexible soft touch feeling, smooth or matte feeling by surface cover coating with oil coating or PU coating.

LOGO: it is available to add your logo/icons on the silicone rubber sleeve, with silkscreen printing, laser etching, pad printing, embossed, debossed, etc.

Color: it is available to customize your own colors, pure color (according to Pantone color code to adjust the color), mixing colors (you could choose several colors for your colorful silicone rubber cases, we use colors mixing to get the colorful style).
