THE Reference for Transmission Measurement

Quality inspection prior to laser processing

The transmission properties of two plastic joining partners are decisive for the quality in laser transmission welding. Checking the material properties before laser plastic welding pays off as part of comprehensive quality assurance system. The TMG 3 is a certified measuring instrument that has been traceably calibrated with the cooperation of the Fraunhofer Institute for Silicate Research ISC.

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.

Application Examples

Fit for the line:  In production lines with high throughput or/and high-quality requirements, such as in the automotive industry, integrable systems for laser plastic welding are used. They are directly controlled by the machine control system. The TMG 3 transmission measuring device is connected directly upstream, and can thus avoid quality losses caused by injection molding inaccuracies, for example.

For all types of plastics: Materials of different colors have different transmittance values, which are tested. And the laser-absorbing component does not always have to be black.

For quality assurance: The certified TMG 3 measuring device exports the data – a plus for the underlying software.

 

The color properties of different colored plastics have different transmission values that need to be tested.
