Now many manufacturers are asking for the detection of plastic bottles, which standard should be used?
According to the light industry, the plastic bottles are QB 2357-1998 polyester (PET) bottles without steam
Inspection items: height deviation, perpendicularity deviation and vertical axis deviation
For example, nowadays more and more liquid foods, medicines and other products are sold in various bottles. Containers such as beverage bottles, mineral water bottles, glass bottles and edible oil drums are more widely used. At the same time the bottle quality problem has become increasingly prominent, the vertical axis deviation first bottle will affect the appearance of the bottle, and may cause the filling nozzle can not be inserted into the bottle, the bottle knocked down, will not only make the filling liquid is sprayed on the outside, but also because the liquid spilled on the filling line cause instrument damage. For example, a properly located label. The bottle vertical axis deviation index related to whether the filling nozzle production line can be inserted into the bottle, filling and capping dose is qualified is tight, the label is firm or position is correct, so the index has become one of the physical indicators of bottled container manufacturers concerned. Automatic filling, automatic sealing, automatic labeling is a necessary step in the production process of container container, container index and vertical axis deviation unqualified (i.e. not round bottle) will affect the effect of the implementation of the above steps, may cause insufficient filling, capping lax, tag is if the filling of products for the consequences. The liquid, sprayed onto the production line, and even cause damage to the production line.
To detect the vertical axis deviation according to the relevant data: plastic bottle height is less than 150mm, requirement of verticality deviation is less than 3mm, the height of the plastic bottle 150-220mm, requirement of verticality deviation of not more than 4.5mm, the height is less than the plastic bottle of 220mm, vertical deviation does not exceed the requirements of plastic bottles 6.4mm.
Therefore, it is suitable for the detection of plastic bottles in various factories, and also the standard of CZ-1 bottle perpendicularity deviation measuring instrument produced by our company. It is the standard of QB2357-1998. We hope that we can help each manufacturer.
