NJbinglab PFA Welding & Custom Assembly Technology
Equipment Description
This machine is a precision thermal fusion butt welding system specifically designed for the connection of high-purity and corrosion-resistant PFA (Perfluoroalkoxy alkane) piping systems.
The system is controlled by a PLC program and integrates high-precision temperature control, servo-driven actuation, and a human-machine interface (HMI). It enables fully automated welding processes, ensuring high weld strength and zero extractables.
The equipment fully meets the stringent requirements for ultra-high purity fluid delivery systems in industries such as semiconductor manufacturing, photovoltaics, biopharmaceuticals, and specialty chemicals.
