The new standard for 3D CT scanning X-Ray penetration

Ming-Li Precision is proud to announce the addition of the ZEISS METROTOM 6 Scout X-Ray 3D CT system to its array of advanced inspection tools. This cutting-edge technology significantly boosts our ability to conduct thorough, non-destructive 3D analyses of plastic injection molded products, ensuring unparalleled quality and precision.

Industrial 3D computed tomography uses X-rays to penetrate the characteristics of objects and combines it with image reconstruction technology to restore 3D digital data. The biggest advantage of using industrial CT is non-destructive testing. The surface does not need to be processed or destroyed to see the internal condition of the workpiece. There are no blind spots in the scan, and it is good at analyzing complex structures. Including dimensional measurement, internal assembly issues, material defects, etc. In the past, the workpiece could only be cut open for inspection, but the "cutting" action would cause other problems and doubts. Nowadays, 3D digital data is obtained through scanning with industrial CT equipment, and perspective drawings and arbitrary cross-section inspections can be realized directly on the computer to accurately measure dimensions.

Features of METROTOM 6 Scout

 

 

     Measurement Applications

      Through X-Ray penetrating scans, all dimensions, including internal

      and external structures, are clearly displayed. This method is highly

      suitable for inspecting the full three-dimensional dimensions of

      complex objects. The grayscale levels shown in the scan data can

      distinguish different materials and their positions.

 

 

 

 

     Temperature Balance System

      The temperature balance system prevents temperature fluctuations

      inside the chamber from affecting measurements. Through the

      design of fans and exhaust vents, upward airflow ensures

      a balanced temperature effect.

Defect Analysis and Internal Defect Detection

Internal defect detection is a major functionality of CT scanning, focusing on examining the porosity within an object. "Porosity" refers to the ratio of void space within a material. 2D porosity is calculated by comparing the area of voids within a specific cross-sectional area to the total area of that section. 3D porosity measures the volume of voids within a specified volume against the total volume of that area. This precise measurement provides invaluable data for assessing material integrity.

CT Multi Part Scan

This is an application case of multi-part scanning. Under the required resolution by the customer, 16 workpieces are placed within the scanning range at once. This means that 16 workpieces can be scanned in a single session. This not only achieves bulk scanning but also increases scanning efficiency. The scanning results show that the details remain very clear, demonstrating the effectiveness of the method.
