Grind and polish the inner wall of the sampling needle with an inner diameter of less than 1 mm to make the roughness less than 0.1 micron
This kind of technology has been blank in China before, and Chinese IVD (in vitro diagnostic products) companies can only rely on high-priced imports.
Now this Technical barriers has been broken by Chinese companies
SZZK Precision Technology Co., Ltd. has overcome this technical problem after several years of research and development, and has mastered the core technology of mirror polishing of the inner wall of metal and non-metal capillary tubes. Now it has cooperated with more than 70 domestic and foreign IVD companies in the precision micro-sampling needle business.

Inner wall mirror polished capillary
SZZK has mastered the core technology of mirror polishing of the inner wall of metal and non-metal capillary, which can completely solve the core technical problem of mirror polishing (Ra<0.1μm) of the inner surface of the metal capillary (ID<1.0mm) of IVD precision micro-sampling needle. This technology broke the international technology monopoly and filled the domestic gap to reach the world's leading level.
According to reports, the company has realized the mass production of IVD precision micro-sampling needles, and has established business cooperation with more than 70 well-known IVD companies at home and abroad.
The Coronavirus (COVID-19) pandemic at the beginning of this year caused severe damage to many companies and also brought opportunities to many companies. Liu Zhongqun said that since March this year, SZZK has received many orders for IVD precision micro-sampling needles used in chemiluminescence technology.
The mirror polishing technology for the inner surface of the metal capillary tube is widely used, not only in the field of IVD, but also in the fields of chemical industry, aerospace, scientific research, food, medicine, and military.
