For any kind of packaging bottle, testing the vertical axis deviation index is of vital importance to the quality of the bottle, which is more important in the quality of medicinal glass bottles. This paper takes the “ RBT— A Vertical Axis Deviation Tester †developed by Jinan Saicheng as an example to conduct a special test on the vertical axis deviation of freeze-dried powder injection bottles provided by a pharmaceutical company. Through the detailed records of the test process, test results and other data, it provides a reference direction and method for the majority of enterprises in need.
1 , the implementation of standards
YBB00192003 "Vertical Axis Deviation Measurement Method"
2 , test sample Â
Medicinal powder injection bottle ( Note: This sample is provided by customers of Jinan Saicheng )
3 , testing equipment
The “ RBT- A Vertical Axis Deviation Tester †independently developed by Jinan Saicheng has met and complied with several national and international standards: “QB2357-1998 Polyester (PET) Non-sparkling Beverage Bottleâ€, “QB/T1868-2004†Standards for polyethylene terephthalate (PET) carbonated beverage bottles, national pharmaceutical packaging containers YBB00192003 "Vertical axis deviation measurement method".
4 , the testing process
(1) First clamp the sample on the horizontal rotating chassis, make the bottle mouth contact with the dial indicator, and rotate 360° to read the large value and the small value. The difference between the large value and the small value is 1/2. Deviation value. (Remember: if using a bottom plate with a V-shaped block, hold the sample against the V-shaped block and apply a downward pressure to the sample in the direction of 45° from the horizontal plane and rotate the glass bottle. Cans 360°)
(2) Make a note of the large and downward distance between the outside of the edge of the bottle and the fixed point. The vertical axis deviation is half the difference between the measured large value and the small value.
(3) The accuracy of the measured value shall be not less than 0.1 mm.
(4) Correct the vertical axis deviation obtained from the actual measurement according to the accuracy.
5 , test results
   According to the standard, the final value of zui cannot be less than 0.1mm, otherwise it needs to be retested.
6. Conclusion
   The “ RBT- A Vertical Axis Deviation Tester †developed by Jinan Saicheng uses imported core components, which makes good use of the high concentricity of the three-jaw self-centering chuck, with a set of heights that can be adjusted freely. The bracket with degree of freedom can meet the verticality deviation detection of important parts such as bottle body and bottle shoulder, and has the advantages of high centering precision and high measurement precision. It is widely used in scientific research units, food, medicine and other industries. Bottle container manufacturer.
In addition, according to national and industry standards, medicinal powder injection bottles need to be tested in addition to the vertical axis deviation, but also need to seal, medicinal powder injection bottle , wall thickness, puncture force, opening force, tensile strength, etc. The test of indicators, and Jinan Saicheng as a domestic old-fashioned pharmaceutical packaging material testing enterprise, has developed nearly one hundred instruments in more than ten years, which can fully meet the testing needs of users for different test indicators.
