Preform coating system Italy’s Bonino Group collaborated with Chem-Trend and Steidle, a German maker of micro-spraying lubrication systems, to develop this system for applying a coating agent to PET bottle preforms. Bonino brought its expertise in orientation and sorting systems to develop a portable unit that positions preforms so they can be individually coated immediately after being injection molded. The system can be adjusted to accommodate nearly all preform designs and sizes.
What’s new? The system, which was created specifically to work with Chem-Trend's Lusin Lub O 32 F, a food-contact-compliant coating agent that combines the effects of a lubricant and a release agent. It also features a specially designed device to prevent the coating agent from entering the preforms.
Benefits Improved preform quality. The system uniformly coats bottle preforms, which drastically reduces the scratches they sustain when they are loaded and unloaded from bins. The coating also improves bottle demolding and eliminates bottle jams on conveying lines. The system avoids the drawbacks of competing devices that spray coatings randomly, such as poor coverage, wasted coating agent and unwanted materials inside the preform.
