Bottle preform stress tester

　　Bottle preform stress testerProduct Introduction: A testing equipment used to inspect the quality of PET bottles, mineral water bottles, and other products. Observe whether the stress it experiences after completion (under non natural effects such as compression, vertex angle, forced bending, etc.) is uniform and exceeds the standard.

　　Bottle preform stress testerA qualified preform is the key to successful bottle production. Unqualified bottle preforms (such as burrs, shrinkage, yellowing, excessive crystallization, uneven coloring, whitening of the bottle body, short preforms, etc.) can lead to various problems such as inability to blow the bottle, inconsistent wall thickness of the finished product, easy cracking, opacity, etc. The main reason for these unqualified bottle preforms is that the production process has changed, such as inconsistent temperature control, injection speed and pressure, melt adhesive temperature and back pressure, screw speed control, cooling time and cooling effect. Controlling the consistency of these process parameters is the key to ensuring the quality of bottle preforms. The basis for ensuring the consistency of process parameters lies in the early warning and traceability of problems, which requires the assistance of testing instruments to achieve.

Common PET bottle testing instruments include: preform polarization stress tester, plastic bottle vertical load testing machine, vertical axis deviation tester, bottle wall and bottom thickness tester, cap sealing tester, carbon dioxide tester, constant temperature drying oven and other testing equipment.
