Medical Device Silicone Knob Medical Grade Silicone Biocompatibility Index Energy Head Factory

I. Raw Material Specification
The silicone knob products are manufactured using 50 Shore pure medical-grade silicone raw materials, with no recycled secondary materials or adulterated auxiliary ingredients. The raw materials meet the industry standards for medical device production, serving as high-end silicone substrates suitable for medical scenarios.
The 50 Shore medical-grade silicone features moderate hardness, balancing flexibility and structural stability, with excellent medical compatibility and safety performance. The raw material itself is non-toxic, odorless, non-sensitizing, and free of harmful substance precipitation. It has passed biocompatibility testing, allowing direct contact with human skin, mucous membranes and medical liquid medicines without causing corrosion or contamination. Meanwhile, the material boasts outstanding resistance to high and low temperatures, aging, and acids & alkalis. It can undergo repeated high-temperature sterilization and disinfection cleaning, resisting deformation, cracking and yellowing, and maintains stable physical properties and appearance during long-term service.
Compared with ordinary industrial silicone, medical-grade silicone delivers higher purity and far fewer impurities, along with superior air tightness, anti-slip performance and tactile texture. It fully satisfies the stringent requirements of medical devices for supporting parts in high precision, high safety and high durability.

III. Production Process
We specialize in custom processing of silicone products for medical devices, adopting standardized and refined production procedures throughout manufacturing. Relying on integrated compression molding technology with vulcanizing machines, combined with a quality inspection system in dust-free workshops, we control product precision and yield rate from the source to meet high-quality supply demands in the medical industry.
1.Raw Material Pretreatment
The incoming 50-Shore medical-grade silicone raw materials undergo screening, refining and degassing to eliminate internal bubbles and impurities inside the materials. This ensures material uniformity and lays a foundation for high-precision molding of finished products, completely avoiding defects such as air holes, blemishes and uneven stress distribution in finished goods.
2.Precise Mold Alignment
High-precision steel molds are custom-made according to customized dimensions and structural parameters of medical device accessories and silicone knobs. Mold precision is controlled within an extremely narrow tolerance range of the industry, guaranteeing consistent and uniform dimensions, arcs, slots and textures for every product, which matches assembly standards of all types of medical equipment.
3.Integrated Compression Molding via Vulcanizing Machine
Fully automatic vulcanizing machines perform high-temperature and high-pressure compression molding, completing the full cycle of product shaping and vulcanization curing in one step without secondary splicing or secondary processing. The integrated molding process delivers compact product structures with uniform density and excellent overall flexibility that resists breakage. It effectively improves the product’s sealing performance, anti-slip property and assembly tightness, thoroughly eliminating drawbacks of spliced products such as loose fit, gaps and poor durability.
4.Refined Post-treatment
Molded products go through edge trimming, deburring and flattening polishing. All edges and corners are smooth without sharp edges, and surfaces are delicate and defect-free to satisfy precision assembly requirements of medical equipment while delivering comfortable hand feel during use.
5.Full Inspection Procedure in Dust-free Workshop
All finished products undergo full inspection in dust-free clean workshops, differing from conventional sampling inspection with 100% full screening. Quality inspectors test core indicators one by one, including dimensional accuracy, surface blemishes, air tightness, flatness, hardness and flexibility. Defective and substandard products are strictly rejected to prevent contaminated, dusty or flawed goods from entering the market, ensuring all delivered products fully meet cleanliness, safety and precision standards for medical device applications.
