Nitrogen Gas Physical Foaming Coaxial Cable Production Line

We continually bring new and technologically advanced coaxial cable
equipment to the market. This machine model adopts a double puller
technology and increases the machinery's stability. Also, it adopts
a computer (PLC) and controlling system and our company developed high
pressure nitrogen gas injection system allowing for the production of
stable and reliable cables.

Cables are minute-foamed, uniform and with a smooth surface. Furthermore,
to satisfy the needs of many cable manufacturers, we also supply
upgrading services. Low pressure foaming machines and low pressure gas injection
devices can be upgraded, and we supply full sets of advanced production technology.
