Why do you place scrap on both sides of the hot plate when operating the belt connector with an air cooled press machine?
When the belt is hot-melt welded, the heating zone is only at the two ends of the belt joint. If the hot plate can not be placed on the remaining parts of the expected angle, then the hot melt belt may be due to the edges without obstruction, causing the belt surface (such as PVC / PU) melt overflow, affecting the first effect. Once the boot heating in the absence of corner pieces and the hot plate left vacant circumstances, it may cause excess temperature long parts, triggering hot press safety protection function, so the hot press stop to heating, then leading to abnormal termination of the belt connector.
We can provide air cooled press machine and water cooled press machine. Looking forward to your orders.
