Product Overview
We are a professional manufacturer of ISO 14572 Vehicles Core Sheathed Cyclic Bending Testing Machines.
Model ZLT-JDW1A is specifically designed to perform cyclic bending tests by swivelling movements in accordance with ISO 14572 Clause 7.3, Figure 1.
This apparatus evaluates the bending endurance of round, sheathed, screened and unscreened single- or multi-core cables (60V and 600V), ensuring compliance with international automotive cable durability standards.
Applications
Durability testing of vehicle cables and wiring harnesses
Quality control in automotive cable production lines
R&D verification for new cable designs
Compliance testing to ISO 14572 requirements
Key Features
ISO Standard Compliance – Fully meets ISO 14572 Clause 7.3, Figure 1 test requirements.
±90° Precision Swivelling – Accurate swivelling motion on both sides of the vertical axis.
Adjustable Test Parameters – Supports various bend radii and tensile loads.
Automatic Counting & Stop Function – 6-digit counter records cycles and stops when the specimen fails (open circuit).
Customizable Power Supply – Available in 220V/50Hz or other voltages upon request.
Sturdy Construction – Designed for long-term laboratory and production use.
