The measurement of plastic parts

The measurement of plastic parts is an important step in the manufacturing process to ensure that the parts meet requirements and quality is ensured. Measurement can be performed using various methods, including CT (Computed Tomography) or laser scanning.

CT is an imaging technique used to create a 3D representation of the inside of an object. In CT measurement of plastic parts, the part is placed inside a CT and exposed to X-rays. The X-rays penetrate the material and create images, which are composited to create a polygon model of the part. By analyzing this model, deviations from specifications can be detected and corrected.

A laser scanner is an optical measurement device used to scan the surface of an object and create a point cloud or polygon model. In the measurement of plastic parts using a laser scanner, a laser beam is directed onto the surface of the part and received by a sensor.

Both methods have advantages and disadvantages. CT is ideal for measuring parts with complex geometries or internal structures, as it can make the inside of the part visible. Laser scanners are ideal for measuring surfaces and can provide very precise measurements. However, both methods are expensive and require specialized equipment and trained personnel.

Overall, CT and laser scanning are important tools for measuring plastic parts. They enable manufacturers to ensure the quality of their parts and detect deviations before the parts are put into use. By using these technologies, manufacturers can improve their processes and ensure higher quality and reliability of their products.
