3 reasons why quality assurance should begin with residual torque

It's a fact of life: quality assurance is vital to retain customers. Improving the quality of a product can be overwhelming. One may wonder: where to begin?

Any action taken may improve quality, but there are a few good reasons to start with quality audits on the joints. Below are the main reasons why.

1. To optimize production

They say ignorance is bliss. However, this is not when it comes to a manufacturing plant.

Data and KPIs are essential to keep everything running smoothly. Knowing how much torque is left by production in a joint is vital to fine-tune the production process.

If done properly, residual torque checks can help production manager understand if dynamic torque is to be increased or decreased on their tightening tools.

2. To catch issues before the product is delivered

Have you ever had a product that was poorly built and came apart after you used it a few times? It's likely the manufacturer was not even aware there was an issue.

You can visually check a product to look for defects, but what do you discover about a screw by visually inspecting it? A joint could seem alright but it could have too little torque to withstand normal use. A residual torque check catches these faulty joints before they reach customers.

3. To deliver the highest product quality

During the design and prototype phase of a product, engineers will define the clamping load for each joint,. But how does one set the production line correctly to be sure that you have the right clamping load?

Residual torque checks on the prototype help find the relation between clamping load and dynamic torque. This relation will help set the production line and choose the tools it requires.

Luckily, the STwrench has a patented algorithm for residual torque checks. By analyzing the trace from a joint in real-time, it will guide operators with a vibration as soon as the residual torque point is found to reduce overloads.
