UL 758 Wire Extrusion Test Apparatus

What is the UL 758 Wire Extrusion Test Apparatus？

ZONSKY UL 758 Wire Extrusion Test Apparatus is a specialized device used to assess the mechanical integrity and adhesion quality of insulation on wires according to UL 758 standards. This apparatus evaluates the extrusion process by applying controlled pressure and heat, testing the insulation's thickness, uniformity, and bond strength to the conductor. Suitable for 20AWG~14AWG insulated wire anti-extrusion test.

Compliance： "Crush Resistance Test" test in Section 27 of UL758-2016 "Appliance Wiring Material".

Advantages of the instrument:

1. The machine structure adopts aluminum extruded sealing plate treated with high-grade baking paint, built-in high-precision, low resistance, no gap double roller screw and guide column, which improves the load efficiency and structural rigidity;

2. The control system adopts Panasonic all-digital AC server to control the AC servo motor with high response frequency to ensure high efficiency of the transmission system, stable transmission, low noise, and speed accuracy can be controlled within ±0.2%;

3. The microcomputer system uses a commercial computer as the main control machine, and cooperates with the company's professional test software to complete all test parameter settings, work status control, data collection, processing and analysis, and result display and printout;
