Fatigue Testing Machines ⇓
Cometech QC-104 MIT Folding Endurance Tester
Key Features
-
Durability Evaluation: Designed to determine the number of folding cycles a material can withstand under a specific tension and angle (Standard +135° to -135°) before failure.
-
Smart Auto-Stop Mechanism: * Conductive Materials: Automatically stops and records cycles upon loss of electrical continuity (Ideal for Flexible Printed Circuits – FPC).
-
Non-Conductive Materials: Stops once the specimen physically breaks (Suitable for paper, foils, etc.).
-
-
2.8″ Touch Screen Interface: Provides an intuitive platform to set folding speed, target cycles, and view the estimated remaining test time.
-
Customizable Parameters: Offers various folding head radii (R) and grip intervals to match specific testing standards and material thicknesses.
-
Precision Control: Maintains a steady folding speed (Standard 175±5 CPM) to ensure consistent and repeatable test results.

Cometech QC-659 Electric Plug/Cord Bending Tester
Key Features
-
6 Independent Test Stations: Capable of testing 6 sets of wire or plugs simultaneously, with individual counters for each station to ensure precise data for every sample.
-
Automatic Breakage Detection: The system automatically detects when the internal conductor snaps (Open Circuit), stops the counter for that specific station, and records the endurance index.
-
Color Touch Screen Controller: Features a modern touch-screen interface for easy setup of test parameters, cycle monitoring, and speed control.
-
Adjustable Swing Angles: Highly flexible testing with adjustable bending angles including ±30°, ±45°, ±60°, ±75°, and ±90°, supported by a built-in angle indicator.
-
Safety & Control: Includes multiple stop functions (breakage stop, preset cycle stop, and pause) along with an emergency stop button for enhanced operator safety.
Technical Specifications
-
Conforming Standards: GB/T 14471 and other relevant wire testing standards.
-
Number of Stations: 6 Sets (6 individual counters + 1 master counter).
-
Swing Angles: ±30°, ±45°, ±60°, ±75°, ±90° (Adjustable).
-
Test Speed: 10 – 120 CPM (Cycles Per Minute) with ±2% accuracy.
-
Counterweights: Included sets of 6 (100g, 200g, 300g, 500g) to apply tension to the cords.
-
