Dana Hanson, president of PTi, a manufacturer of plastic sheet extrusion equipment, said, “We have developed a unique method of changing the layer structure, which is unique in the industry. The ability to change in real time can greatly increase the cost of coextruded product manufacturers. Efficiency and productivity."
Because the plunger cylinder is hydraulically driven and features a unique flow design that allows the plunger position to be changed in seconds, the traditional method requires some equipment to be disassembled, which can take several hours. Directional valves can be used on new or existing equipment. It is reported that PTi's unique reversing valve has been awarded a US patent. With this valve, the processor can quickly change the position of the extrudate of the two extruders in the co-extruded structure without the need for cumbersome assembly processes or production shutdown. And waste a lot of money. Therefore, this invention is more advanced than before.
