Hollow Sheet Die

The key to high-quality hollow sheets lies in the internal rib structure. Hundreds of hollow channels must maintain consistent wall thickness and cell geometry across the entire sheet width, requiring precise die lip design and zoned air flow control. GMA Hollow Sheet Dies incorporate multiple patented core insert and flow channel designs to maintain stable hollow structure formation through precise air flow adjustment. They also support co-extrusion for functional cap layers and colored structures, making them an ideal solution for high-value hollow sheet production.
