Engineered parts are classified as parts that need various manufacturing process. They are engineered in sync with the design requirements of the customers. They are specifically designed items or sub-assemblies that include complex, critical – to – function components.

However, they undergo various testing methods before finally dispatching them to the end users. Here are some of the methods that professional manufacturers of engineered parts follow in their facility.

1. Visual Inspection: This is the traditional method that helps to detect the surface defects on the engineered parts. It is the process of examining the engineered parts with naked eye to look for the flaws. The inspection specialists use the optical aids like illuminators, mirrors; bore scope and more to enhance one’s capability of visually inspecting the parts. Cameras, computer systems and digital image analyzers are also used to enhance the benefits and capabilities of the visual inspection. It is the most cost-effective, simple and less technologically advanced method.
2. Dimensional inspection: Dimensional inspection ensures the engineering methods and completed engineering parts meet the industry standards and individual requirements. It is the process of determining the measurements of the engineered parts and comparing the results with the specified requirements or tolerances within the drawing of that part. This type of inspection is important for quality control, minimizing product manufacturing cost and enhancing manufacturing capabilities. The various types of dimensional inspection are 3D scanning, reverse engineering, metrology services, CMM inspection services, X-Ray Material testing and more.
3. Surface inspection: Surface inspection of the engineered parts involves the use of angled lighting and smart cameras to accurately detect surface flaws or features in real time. It is used for quality assurance. This inspection provides an automated approach to inspection for inclusions, surface defects, cracks, and missing materials in the engineered parts. AI and Automated deep learning are some of the methods for surface inspection.
4. Functional inspection: Engineered parts are physically inspected based on the criteria, like item characteristics and quality. It is a non-exhaustive task that is reserved only for very specific and justified cases. It guarantees high product quality and safety. It is done to determine the overall condition and functioning of the engineered part. It tests the performance of the engineered parts to ensure the operations as intended.
5. Non-destructive testing (NDT) – It refers to the plethora of inspection method that allows inspectors to evaluate and collect data about material, system or component without permanently altering it. It is a valuable technique used by many industries. These tests do not damage the parts that are being tested. Various kinds of NDT testing include Visual inspections, ultrasonic testing, vibration analysis, magnetic particle testing, X-ray inspection and penetrant testing.
6. Destructive testing: This method of testing aims to deform or destroy the engineered part to highlight its failure. It uses a series of tests to know how the engineered parts perform under a certain load. It is type of testing that determines how a component will behave under pressure until it fails. It analyzes the material’s behavior, structure or product until the point of breakdown or failure. The various types of destructive testing include corrosion testing, hardness testing, aggressive environment testing and more.

Experienced engineered parts manufacturers use the cutting-edge testing methods to ensure the final product meets the requirements of the project.
