Class 100,000 Cleanroom: Aobo Silicone Quality Upgrade

Aobo Silicone has earned third-party Class 100,000 cleanroom certification, meeting international production cleanliness standards. We control contamination risks at the source, guaranteeing the quality and safety of food-grade and medical-grade silicone ear tips and precision products, and delivering stable, compliant supply chain solutions to global B2B customers.

1. Class 100,000 Cleanroom: International Standards, Authoritative Verification

A Class 100,000 cleanroom is a specialized production space designed for products requiring high cleanliness. It precisely controls airborne particles, microorganisms, and environmental contaminants, making it an essential prerequisite for manufacturing food-contact and medical-grade silicone products.

Built in strict accordance with ISO 14644-1 international cleanliness standard and GB 50073-2013 national standard, Aobo Silicone's cleanroom has passed comprehensive testing by an authoritative third-party organization, with all indicators meeting and some exceeding requirements:

· Airborne particles ≥0.5μm: ≤3.52 million/m³; particles ≥5μm: ≤29,300/m³

· Airborne bacteria: ≤500 CFU/m³; settling bacteria: ≤10 CFU/plate

· Constant temperature 22-26°C, constant humidity 45%-65%, 15-20 air changes/hour

· Pressure differential ≥5Pa between adjacent zones, effectively blocking external pollutants and cross-contamination

2. Clean Manufacturing: Boost Your Product Market Competitiveness

For food-grade and medical-grade silicone products, clean manufacturing is not an add-on but the core foundation of product compliance and quality. Our Class 100,000 cleanroom covers the entire production process, bringing three core advantages to your products:

· Flawless appearance and safety compliance: Complete elimination of dust, hair, and microbial contamination ensures silicone ear tips have smooth surfaces free of black spots, burrs, or odors. Fully compliant with FDA, LFGB and other international food and skin contact safety standards, significantly reducing your product compliance risks and customer complaint rates.

· Longer service life and stable performance: A contaminant-free environment protects silicone molecular structure from damage, significantly improving product resistance to aging and yellowing. Elasticity and sealing performance remain stable over time, extending end-product lifespan and increasing consumer repurchase rates.

· Precise dimensions and superior acoustic performance: Clean manufacturing enables tighter dimensional tolerance control. Ear tips have smooth, uniform inner walls that fit better in the ear canal, delivering superior noise isolation and low-frequency response, helping your audio products create differentiated sound experiences.

3. End-to-End Quality Control: From Raw Materials to Finished Products

Beyond the Class 100,000 cleanroom, Aobo Silicone operates under ISO 9001 Quality Management System and ISO 13485 Medical Device Quality Management System, building a full-chain quality control closed loop:

· Raw material control: We exclusively use food-grade and medical-grade liquid silicone rubber (LSR) from imported and domestic first-tier brands. Each batch comes with test reports and undergoes incoming re-inspection for full traceability.

· Production process control: All personnel entering the cleanroom must follow complete gowning and air shower disinfection procedures. Production equipment is regularly cleaned and calibrated, with full process parameter recording to ensure process stability.

· 100% finished product inspection: Equipped with multiple automated optical inspection (AOI) systems, every finished product undergoes full appearance and dimensional inspection to prevent any defective products from reaching the market.
