Medical-Grade Cleanroom Standards — Anzhan Ensures Reliability in Every Detail

In the modern precision manufacturing and medical device industries, the cleanliness of the production environment directly determines product quality. Changzhou Anzhan Precision Instrument Technology Co., Ltd.'s Class 100,000 cleanroom has laid a solid foundation for high-standard manufacturing.

The cleanroom is equipped with industry-leading production and testing equipment. CNC machining centers achieve high-precision component processing; mirror EDM machines enhance the surface quality of molds; wire-cutting machines accurately handle complex components; precision grinders ensure the surface precision of parts; and coordinate measuring machines provide precise data support for quality inspection.

A full-process control system runs through the entire production process. The temperature and humidity control system stabilizes the environment at 22±2℃ with a relative humidity of 50%±5%, which not only ensures the stability of material properties but also reduces the risk of equipment failure. The air purification system adopts three-stage filtration of primary, medium and high-efficiency filters. The high-efficiency filter has a purification efficiency of over 99.97% for particles larger than 0.3 microns, greatly reducing the pollution risk.

Personnel operations follow strict specifications. To enter the plant, one must change into clean clothes and be showered in an air shower room. During production, professional gloves must be worn to avoid pollution.

The advantages of the clean workshop are significant: in terms of production efficiency, the rejection rate is greatly reduced. For example, the rejection rate of a certain precision medical device component is 10-15% in the ordinary environment, while it is only 1-2% in the cleanroom; in terms of product quality, it effectively controls microbial pollution, improves the safety of medical devices, and significantly enhances the performance and stability of high-precision products. Customers report that the frequency of equipment failures using its parts has been reduced by 30%-40%.
