Optimizing the Injection Mold Calibration Process Using METROTOM CT

Factors Affecting Quality

The quality of plastic components manufactured using injection molding is influenced by numerous factors, such as the mold itself, various manufacturing parameters, and the type of plastic used. For instance, shrinkage characteristics can affect the final dimensions of the product, and these characteristics are also influenced by the other factors mentioned above, making precise predictions challenging.

 

 

Mold Calibration Process

Due to the difficulty in predicting the quality of injection molds, the molds often need to undergo multiple rework processes until the molded products meet quality standards. Measurements must be taken during each calibration, and the results are then used to modify the mold. The challenges faced during any calibration step include:

• Collecting as many uniformly distributed precise measurement points as possible.
• Comparing the measurement results with CAD data.
• Ensuring the accurate integration of calibration data with the mold shape.

 

 

METROTOM CT

To streamline the entire mold calibration process, computer tomography (CT) can be used. CT can capture all internal and external dimensions and structures. Components can be segmented and displayed through software, and the advantages of CT scanning include:

• No need to destroy the object during the inspection process.
• Significantly reduced inspection time.
• No risk of deformation during the inspection process.
• The ability to capture the entire component provides more comprehensive information, not just individual parts. This can reduce the number of calibration cycles required. The CT system offers high accuracy and traceable results.
