Thermoforming of Foil

To avoid local burning and crack formation, an even temperature of the material is of importance during thermoforming processes. Thermal imagers are used to retract the temperature regime of equipment. Punctual measuring pyrometers take care of the temperature control during production by monitoring defined measurement points.

Injection Moulding

To avoid a distortion of building elements during injection moulding processes, the process can be monitored by thermal imagers. By measuring the molded parts when opening the mold, temperature overstepping or undershoot (hot spots, cold spots) can be detected and the molding temperature can be adjusted on time.

PET Bottle Production

The injection blow process is very common for the production of PET bottles. A PET preform (injection molded part) will be heated and pressed into a form by compressed air. To control the preform temperature at different spots, fast punctual measuring pyrometers (response time 6 ms) or the fast thermal imager (frequency 100 Hz) are recommended.
