Siroma-Plast utilizes advanced CT technology to inspect both the internal and external structures of injection-molded parts. This capability plays a key role in quality assurance, product development, and tool optimization processes. Possible steps of a typical component analysed with this technology:
The actual component is scanned in the tomograph. The resolution of the process is 2 microns, however only one raw material type may be analysed at one time
Depending on the size of the work piece, several components may be scanned at the same time. This is especially useful for components with very high cavity counts (32 - 48)
The software separates and singles out the individual components from the multiple scan.
The resulting mesh is then fit onto the actual CAD, where various fitting method may be selected depending on the purpose of the scan (quick check, local analysis, full measurement report etc.)
After fitting, a colour map is used to visualize the differences between the part and the CAD.
Next level of comparison is to measure the actual value of the difference between nominal vs actual part.
The same methodology may be used between two or more actual parts, to detect changes within production, or differences between cavities, as well as optimisation loop part statuses.
To have a better understanding of the part, these elements may be created. These give a more prices view than the point or line scan results of tactile systems, and faster.
Measurements are available in both drawing alignment and datum-based systems, with quantifiable results compatible with any other measurement method. Values defined on features, run-outs or edges can be simulated and evaluated as if measured by tactile or optical systems.
Our CT scanning system supports advanced GD&T analysis. This enables comprehensive verification of critical geometrical features such as flatness, parallelism, concentricity, true position, and runout—even in complex or enclosed geometries that are difficult or impossible to measure with traditional tactile or optical methods.
Our in-house CT scanning capabilities allow for precise non-destructive analysis of plastic parts and tools. Cross-sectional imaging enables detailed inspection of internal geometries, wall thickness consistency, and dimensional conformity. Additionally, the system is capable of detecting material defects such as voids, inclusions, sink marks, or internal cracks—making it a powerful tool for both quality assurance and root-cause analysis.
