Optimization of IR heating systems in PET blowing


Plastic bottle are generally made out of PET polymer that can be easily deformed by exposition to temperatures close to their glass transition temperature. The manufacturing of such bottles is done by blowing of a plastic preform under heat against a bottle shaped mold.
The heating system of these manufacturing lines is composed of infrared lamps emitting heat in all directions that are guided towards the plastic preform thanks to a reflector. 
Unlike traditional metallic and ceramics reflectors, SilPower offers excellent reflective properties thanks to a tailored diffusive structure made out high transparency silica, enabling energy savings thus reduced Total Cost of Ownership and consistent manufacturing. SilPower expands significantly less with temperature compared to traditional solutions preventing the need for the dilation gaps of assembled reflectors and making it an easy to install.
