80-Meter Long Foaming Furnace
Category：Tunnel Oven Production Line
Introduction
The 80-meter long foaming furnace is an industrial-grade, ultra-long continuous thermal processing equipment mainly used for heating, foaming, and curing molding of polymer materials.The equipment adopts a segmented independent temperature control design, featuring extremely high temperature uniformity and a stable conveying system. It ensures uniform foaming of materials under long-duration and long-distance high-temperature conditions, making it a core equipment for large-scale and high-efficiency continuous production.
Applications
Plastic Foaming:
Used for continuous foaming of plastic sheets or rolls made of materials such as PE (Polyethylene), EVA, and PVC.
Rubber Foaming:
Used for vulcanization foaming of rubber sealing strips, insulation pipes, and foam rubber pads.
New Building Materials:
Used for continuous production of polyurethane (PU) insulation boards and exterior wall insulation materials.
Automotive Interior Materials:
Used for manufacturing foam cushioning and sound insulation materials such as automobile headliners and door panels.
