Crimp Tool Calibration

Crimp tool calibration ensures that your tool is operating in accordance with its original specifications and that the correct force is used to attach the crimp to the cable.

We are able to calibrate and verify all makes and models of crimp tool.
We pride ourselves on our quick turnaround and excellent service and will aim to get your crimp tools back to you to minimise your manufacturing and production downtime.

We are able to pull test samples to destruction, or pull and return for a specified period of time if required up to 50,000 Newtons, and are also able to carry out mechanical testing to the following standards.

Crimp Tool Calibration Procedure

Samples of cable and appropriate crimps must be provided with every crimp tool that requires calibration or operator competency checks.

If required, the tool is checked with a Go / No-Go gauge according to the manufacturer’s specifications.

From the supplied tool, cable samples and crimps we will generally create three samples.

To check for mechanical integrity, crimp terminations will be visually examined and if required a pull test will be performed. Tension is applied to the crimped joints and the terminations should be able to withstand this force for a set period of time without degradation or creepage.

The cross-sectional area of the cable will determine the amount of force (in Newtons) that can be applied. We are able to accommodate for a wide range of crimp tools and cables with different cross-sectional areas, including small AWG conductor sizes through to 2.5mm² for open, pre-insulated crimp barrels and those with conductor sizes of 1.5mm² for closed crimp barrels and also large cables in excess of 95mm².
