Shanghai LiuSen T-die Technology Co., Ltd. with the idea of “Technology changes life and knowledge changes fate”, was founded by professional T-die design engineers. 
Our company has researched and developed the PVC foam board T-die for many years and we have accumulated lots of experience on sheet and board extrusion T-dies. With many times designing and testing, we have successfully developed a new PVC foam board T-die which has no choke bars, no movable die lip, elastic micro adjustment die lip gap. This T-die has solved the problems of short running cycle, uneven density, mechanical mark on the product surface.
