Center Line Control in Production
The factory pays close attention to the center split position. If the center line moves, the hard and soft ratio changes. Too much hard material makes the sleeve too hard. Too much soft material makes the sleeve too soft. Workers adjust the die head. They check the first piece. They measure the center line. They check the part every two hours. They record the data. This process keeps each batch stable. The factory has made co-extruded parts for many years. It uses two extruders. It uses a composite die head. The team knows PVC and TPE co-extrusion. The hard and soft parts must bond well. If the temperature is wrong, the layers can split. If the speed is wrong, the surface can wrinkle. Workers adjust temperature. They adjust pulling speed. They run a peel test. They keep the layers together.
