Customer
Our client is a global automotive supplier, leader in protection and routing solutions for on-board electrical and fluid networks.
Tested product
The products tested were corrugated or smooth tubes of different diameters, lengths and materials.
Objective
Carry out bursting tests on plastic or flexible tubes by subjecting them to internal pressure.
Problematic issues
The bench must be able to test both :
- long corrugated tubes. These tubes deform a lot when pressurised.
- short smooth tubes. These tubes have a very high resistance to pressure.
The pressure regulation must be very fine and linear.
Solution and result
LF Technologies has developed a static pressure generator to meet the need for both volume and accuracy of pressure application.
The static pressure generator is a motorised syringe with a small cross-section to ensure accurate pressure application.
In order to inject sufficient liquid into the corrugated tubes, the static pressure generator is equipped with an automatically controlled valve, allowing the pressure in the tube to be maintained until the syringe is refilled.
