JINPAT Slip Rings Empower Precision Coating Machinery Manufacturing with Innovative Technology

In high-precision industrial equipment suchas coating machines, JINPAT slip rings have emerged as a core rotary connectionsolution due to their unique technological advantages. As critical devices forapplying coatings to substrates like films and paper, coating machines require360° continuous rotation to transmit power and signals while enduring harshconditions such as high temperatures and humidity.  

JINPAT’s hollow shaft slip ring series,specifically designed for coating machines, not only supports operatingtemperatures up to 150°C but also integrates servo motor encoder signals andpower transmission through modular design. Featuring specialized shieldingstructures and precious metal contacts, the LPT slip ring achievesinter-channel isolation exceeding 45dB between encoder signals and powercircuits, fundamentally eliminating signal distortion or bit errors caused bypower interference. This "signal-power hybrid transmission"technology simplifies equipment wiring while ensuring millimeter-levelprecision in coating speed and tension control by servo systems.  

To address the demand for pneumatic actuatorsin coating processes, JINPAT innovatively integrates pneumatic pathways intoits slip ring systems. The LPT slip ring incorporates pneumatic hydraulicrotary unions via a central bore design, enabling stable transmission of 12circuits of 10A high-current power, 18 control signals, and 1 compressed airline. The physically isolated design of pneumatic and electrical circuitsensures that air pressure media do not corrode electrical contact surfaces.This electro-pneumatic integration allows coating machines to synchronizepneumatic operations such as glue roller pressure adjustment and vacuumadsorption, significantly improving coating uniformity and roll-changeefficiency. Combined with an IP65 protection rating and salt spray resistancetreatment, JINPAT slip rings maintain reliable operation even in environmentswith splattering coatings.  

With nearly 30 years of expertise inindustrial slip rings, JINPAT offers deep customization for coating machines’unique requirements. For specialized needs such as high-speed rotation andlarge bores (up to 820mm), the LPK slip ring employs PCB-separated structuresand precious metal cluster brush technology, achieving lossless transmission of20 signals within an ultra-thin 6mm profile. This blend of technical expertiseand customization capability positions JINPAT slip rings as a core enabler foradvancing coating machines’ intelligent capabilities and production efficiency.
