How to Measure the Internal Dimensions of a Blind Hole?

A blind hole is a hole with a closed bottom, it’s the opposite of a through hole, which is open on both ends. That closed end blocks most standard inspection tools from reaching where you need to measure, which make blind holes difficult to inspect.Standard gauges have a “blind spot”… <a href="https://www.plastiform.info/en/blog/quality-assurance/how-to-measure-the-internal-dimensions-of-a-blind-hole/" class="read-more">Read More</a>

Radiographic Testing – How To Guide

Radiographic testing is a non destructive testing method that uses ionizing radiation to reveal the internal structure of a component without damaging it.By passing X rays or gamma rays through a material, you can capture an image of what is beneath the surface.Internal defects like cracks or… <a href="https://www.plastiform.info/en/blog/quality-assurance/radiographic-testing-how-to-guide/" class="read-more">Read More</a>

Visual Testing – What is it? How to Implement it?

Visual Testing (VT) is the examination of material surfaces and workmanship using the human eye, often aided by optical instruments, to identify discontinuities without damaging the component. It is the most fundamental non-destructive testing method used in mechanical engineering today.I used to treat visual checks as an… <a href="https://www.plastiform.info/en/blog/quality-assurance/visual-testing-what-is-it-how-to-implement-it/" class="read-more">Read More</a>

Statistical Process Control (SPC) – Definition and Interest

Statistical Process Control (SPC) is a method that uses statistical techniques to monitor and control a manufacturing process. I used to assume that if you set a machine up perfectly, it should produce perfect parts indefinitely. If a dimension drifted, I would immediately tweak the settings to fix it. But… <a href="https://www.plastiform.info/en/blog/quality-assurance/statistical-process-control-spc-definition-and-interest/" class="read-more">Read More</a>

How does Phased Array Ultrasonic Testing (PAUT) Works?

Phased Array Ultrasonic Testing (PAUT) is an advanced non destructive testing method. It lets you inspect materials for flaws using a group of small ultrasonic probes, with no need to damage the component. You don’t have to move the probe like in conventional single probe tests. It… <a href="https://www.plastiform.info/en/blog/quality-assurance/how-does-phased-array-ultrasonic-testing-paut-works/" class="read-more">Read More</a>

What is Pneumatic Testing ? How Does it Work?

Pneumatic testing is a method used to check if a pressure system like a pipe, tank, can safely withstand the expected pressure.Instead of filling it with water, the system is pressurized with air or another safe gas. This helps reveal whether it is strong enough, free from leaks, and safe… <a href="https://www.plastiform.info/en/blog/quality-assurance/what-is-pneumatic-testing-how-does-it-work/" class="read-more">Read More</a>
