The hot runner is the heart and artery system of the mould; at least that’s how we like to think of it.” Árpád explains that on one end, there is one main channel that receives the liquid from a pump, and the hot runner has to deliver this material to all the different areas and consumers, while carefully maintaining the conditions and properties of the material. When one small corner of the melt distribution falters, the impact can eventually be dramatic. It can lead to quality issues, and cycle time losses and can even force complete system shutdowns. All of these effects are detrimental in terms of CO2 emissions. “A slower cycle time mostly means more energy consumed per tons processed. A blocked cavity means more hot runner power is consumed per cavity since the manifold system is still fully heated. And a defective preform eventually is basically more waste-material, which increases CO2 loss per definition since energy that was consumed to Cup preforms for fresh desserts 100% RECYCLABLE 3- and 5-gallon UHȴOO SUHIRUPV 100% RECYCLABLE Dairy preforms, in mono & multilayer 100% RECYCLABLE Wine and spirits Preforms 100% RECYCLABLE PET & RPET preforms manufacturer for food liquids Hot runner before and after refurbishment
