Quality inspection prior to laser processing
Inspection of the Preliminary Products
Users measure the transmission properties of plastics with the calibrated LPKF TMG 3. Only a few seconds are needed to verify that the actual transparency values correspond to the target values of the process definition. Material deviations from preliminary processes (compounding or injection moulding) are therefore detected before an unsuitable component enters the production process. The LPKF TMG 3 is calibrated with a measuring standard generated according to DIN EN ISO/IEC 17025 before delivery and shipped with a factory calibration certificate.
Integrated systems for laser plastic welding are used in production lines with high throughput or/and high quality demands, such as those in the automotive industry. They are controlled directly by the machine interface. The production takes place on a continuous line. If the TMG 3 transmission measuring device is connected directly in upstream mode, quality losses caused by injection moulding inaccuracies, for example, can be avoided.
Plastics of different colours have different transmission values that need to be tested.
Here, two components fit together in terms of their material properties.
The laser-absorbing component does not always have to be black.
