Automatic Bottle Cap Torque Tester
Category：Torsion Testing Machine
Introduction
The Automatic Bottle Cap Torque Tester is designed for automatic testing of bottle cap torque performance. It combines electronic technology with precision mechanical transmission and complies with the technical requirements of GB/T 17876.
It is suitable for measuring the opening torque, closing torque, and low-cycle fatigue performance during tightening and opening of threaded bottle caps used for food, beverages, and medical products.
Application
(1) Bottle cap opening torque testing
(2) Bottle cap tightening torque testing
(3) Tightening-opening low-cycle fatigue testing
(4) Threaded bottle container testing
(5) Quality control of food and beverage packaging
(6) Medical and other bottled products
Standards
GB/T 17876 — Plastic Anti-theft Bottles for Packaging
