Since its founding, Kingfa Medical has focused deeply on the disposable glove industry, with continuous optimization and upgrading in product research and development and production processes. Thanks to consistent quality and global services, our products are sold worldwide. We serve clients across healthcare, biopharmaceuticals, laboratory testing, life sciences, aerospace manufacturing, precision electronics, automotive industry and more.
To address common questions from global buyers regarding materials, performance, certifications and production, we have compiled this dedicated Q&A for your reference.
1、Raw material traceability
Q: How are raw materials matched to the positioning of different series of nitrile gloves?
A: We develop exclusive material formulas for three major product lines: medical grade, industrial grade and biodegradable gloves.
The medical series uses high-purity nitrile raw materials, including formulas free of accelerators, ultra-soft formulas and chemotherapy-resistant formulas, which deliver low allergenicity and effective chemical barrier performance.
For industrial protective gloves, we adopt special vulcanization systems and processes to enhance resistance to chemicals, abrasion and tearing.
Our biodegradable nitrile gloves are added with self-developed degradation additives. They meet all protection standards while achieving biodegradability.
All raw materials of our products comply with domestic and international regulations and certification requirements.
Q: What are the advantages of the production formula for nitrile gloves?
A: Compared with natural latex gloves, nitrile gloves contain no latex protein, thus preventing allergies caused by latex protein.
Q: What special designs are applied to the raw material formula of chemotherapy-resistant nitrile gloves?
A: We adopt Kingfa's exclusive vulcanization system and processes to increase the degree of vulcanization cross-linking, so as to enhance the gloves' resistance against chemotherapy agents.
2、Production processes
Q: What production line configuration is adopted for nitrile gloves, and what are its advantages?
A: We use fully automatic high-speed dual-mold production lines. Each line stretches 1.8 kilometers long with a daily output of 1.2 million gloves. Equipped with an advanced artificial intelligence identification system, the lines automatically remove defective products to further improve product quality.
Q: What steps are included in the entire production process of nitrile gloves?
A: Please refer to the picture below for the flow chart.
Q: Why is the chlorination treatment process used for nitrile gloves?
A: Chlorination makes the inner surface of gloves smoother and easier to wear.
Q: What are the differences in production processes between cleanroom nitrile gloves and regular medical nitrile gloves?
A: Cleanroom nitrile gloves adopt dedicated raw materials and exclusive production techniques. The finished products are soaked and rinsed repeatedly with ultrapure water to strictly control ions, particles and bioburden, adapting to application scenarios with different cleanliness levels. Regular medical nitrile gloves are manufactured using medical-grade nitrile materials. Their performance complies with medical standards such as EN455 and ASTM D6319, and no secondary cleaning is required.
Q: How to ensure consistent quality across different production batches of nitrile gloves?
A：
Conduct strict incoming inspection of raw materials to reduce quality fluctuations.
Implement rigorous management and real-time monitoring of production processes to avoid quality issues caused by process deviations.
The production lines are equipped with AI identification systems, automatic feeding systems and automatic batching systems.
Monitor operational status in real time to keep product quality stable.
Establish a sound quality management system to conduct full-process control over production materials and finished products.
3、Final inspection before delivery
Q: What items are included in the final inspection for finished nitrile gloves before delivery?
A: Full visual inspection (checking for major tears, oil stains, black spots, uneven adhesive and other defects) → Pinhole testing → Random sampling for mechanical performance (elongation and puncture resistance) → Packaging inspection → Batch information verification,products can only be delivered after passing all inspections.
Q: What is the standard shelf life of finished nitrile gloves?
A: When stored in a cool, dry and dark environment at room temperature, the shelf life of nitrile gloves in original sealed packaging ranges from 3 to 5 years. Due to special formula features, biodegradable gloves have a dedicated validity period, with storage requirements clearly marked on the packaging.
Q: Do you support third-party pre-shipment inspection?
A:Yes. We welcome third-party inspectors appointed by clients. On-site, we provide:
Unpacking and sampling support
Dedicated inspection space
Calibrated testing equipment
Bulk goods photography (on request)
Access to batch records, certificates of analysis, and QC documentation
