Torque test is a test method that applies a force to a rotating part to measure its rotational force. Torque testing plays an important role in verifying product quality, ensuring safety and durability by accurately measuring the rotational force of rotating parts.


Conducting the test

In automotive components, the forces on the part include shocks and vibrations from driving, and torque from the driver's manipulation of the steering wheel.
The test is conducted with test equipment that CTR has.

  1. Secure the Ball Joint: The ball joint may need to be held in place using a special tool or clamp to prevent it from rotating while performing the torque test.

  2. Apply Torque: A torque wrench is used to apply rotational force to the ball joint. The torque is typically applied in a controlled manner using specified torque values provided by the vehicle manufacturer.

  3. Measure Torque: As torque is applied, the torque wrench indicates the amount of force being exerted. The measurement is typically given in units of torque (such as Nm or lb-ft).


Analyzing the result (Why a high score is bad)

A high score on a torque test inspection result means that too much force has been applied, which can cause damage to the product. This can reduce the durability of the product and shorten its lifespan. So, in general, the lower the score you get from the torque test, the better.
