HDPE Foam Extrusion Production Line
This production line is a high-precision, automated system designed for the physical foaming of polymers such as PE, PS, PP, TPU, PLA, and EVA. It is particularly optimized for producing biochip filter media, sealing strips, and specialized foamed profiles using a patented Supercritical CO2 Injection System.
Developed by our specialized R&D team, the RG90 Production Line integrates our proprietary, patented Supercritical CO2 Injection System with advanced extrusion technology. This innovative system is designed for the one-step physical foaming of strips, rods, and sheets. It serves diverse industries, including eco-friendly filtration, door/window sealing, cushions, and automotive gaskets. Featuring precision electrical controls, high automation, and stable performance, the line offers an environmentally friendly, pollution-free process that requires minimal labor (only 2 operators per shift).
