Metal Casting

An industry where quality is most critical

With metal castings being used in many different industries such as automotive, aerospace, and general mechanical engineering, the requirements for quality assurance are both exceptionally high and diverse. Safety-relevant parts such as aircraft turbine blades or light alloy wheels are usually subject to 100% testing. Comet Yxlon supports foundries in their aim to manufacture prime-quality casting products at competitive prices – and to prevent defects and downtime.

Comet Yxlon X-ray and CT systems are designed to meet the most critical aerospace and defense standards and ensure the safe, reliable inspection of aircraft parts and materials.

Applications of industrial X-rays in foundries

Verification of casting quality, e.g., blowholes and pores

Geometric measurement of inner structures

Wall thickness analysis

Target/actual comparison

Inspection of joints in brake discs

Measurements of cooling channels in pistons

Industrial X-ray or CT scanning It’s all about material density

Evaluating flaws, ensuring material integrity

Typical foundry casting flaws can occur in all casting techniques that involve materials such as iron, aluminum, magnesium, or zinc – with a major impact on product quality. Just one example: If cavities are located just below the surface of the part, they may get opened by further processing such as milling, grinding, or cutting threads. Random inspections help verify the stability of the casting process and thus ensure the quality of the component.

Industrial X-ray or CT scanning? It’s all about material density.

The decision to choose an X-ray or a computed tomography (CT) system is independent of the type of casting process a manufacturer is using. However, the density of the metal, the size of the component, and its wall thickness play an important role in the energy needed. With energies ranging from 20 kV to 600 kV, Comet Yxlon systems for industrial X-ray and CT cover the inspection needs of a wide variety of applications and parts.

Seeing deeper: live-image X-ray inspections with HDR

Classical 2D fluoroscopic inspection has one limitation: It does not give concrete information about the depth position of the discontinuities. With the introduction of high dynamic radioscopy (HDR), Comet Yxlon has developed a method of live-image capable, digital image processing. HDR makes it possible to obtain a good estimate of the depth position while moving the component in the X-ray beam.

Adding perspective with computed tomography

Adding perspective with computed tomography

In comparison with 2D X-ray inspections, computed tomography (CT) provides detailed 3D information about the internal structures of an object, showing the precise position, shape, and size of existing flaws. Since casting molds can change over time and structures become significantly more complex, CT is the solution to address specific issues such as dimensional accuracy, wall thickness measurements, target/actual comparisons, or porosity analysis including statistical evaluation.

Easy operation and automated defect recognition

While Comet Yxlon inspection systems feature a wide range of powerful X-ray and CT capabilities, they are easy to operate by users of different skill levels thanks to their intuitive user interface Geminy. In addition, computer-aided evaluations, also known as “automated defect recognition” (ADR) allow for user-independent inspection decisions.
