Injection molding
The importance of communication between the metrologist and the engineer
Computed tomography is the first choice for dimensional analyzing of injection molded parts.

When the metrologist is sitting next to the engineer
Quality control is of crucial importance in the plastics industry, as even the smallest errors can have serious consequences. Components for medical devices, electrical connections and plastic housings are therefore subject to the strictest quality controls. Plastic products often have to be inspected for porosity, wall thickness and dimensional accuracy. In addition, foreign bodies such as dirt or metal particles can contaminate the finished product. Manufacturers make sure that their products meet the highest quality standards. First article inspection is one way to achieve this, as it ensures that each component meets the required specifications.
The non-contact measurement in the free state eliminates any physical influences on the measurement.
Computed tomography provides support for every type and size of moulding process used for plastics, rubber and polyurethane products. Rubber is commonly used for the manufacture of high performance products such as car tyres and industrial seals.
CT scanning of multi-material parts containing rubber, for example, can detect defects in the bonding of the material.
This information can then be used to optimise the manufacturing process until the final product meets the highest quality standards.

Depending on the component geometry, actual/actual comparisons can be made from the current 3D scan to the 3D data of the last inspection instead of time-consuming measurements.
If the deviations and consequently the wear of the tool are within the tolerance, further measurements are obsolete.
Traditionally, individual points on the warped surface are measured and then compensated using CAD software.
The communication between engineer and metrologist is then often done via tables with measured values and design instructions.
We circumvent this error-prone procedure by generating the compensation data directly from the 3D scan. As an interface for tool correction, full 3D data up to the fully compensated CAD file are then available.
Best practice
Which tools are commonly used for mouldet parts
Computed tomography
- 3D-Measurements
- Porosity and inclusion analysis
- Fiber analysis
- Target actual comparison
- Mechanical troubleshooting
- Wall thickness analysis
Advantages
CT based data aquisition saves time by crossing standard processes. Troubleshooting of invisible situations get simple because of excellent visualisation possibilitys. Converted data can be used in third party tools.
