We develop and manufacture products based on customer needs including hot fluid and gas transfer, freezing prevention and high-pressure specifications.
On an automotive paint line, temperature drift means orange peel, dry spray, rework, and lost production. This article explains why automotive coatings demand precise viscosity control, and where heated hoses work: paint circulation loops, sealant and PVC dispensing, cavity wax protection, and adhesive application. It covers what the environment demands—pressure capability, flexibility for robot-mounted routing, uniform heating, chemical resistance, and audit-ready documentation. We offer customizable electrically heated hoses, high-pressure thermoplastic hoses, and temperature controllers for automotive coating applications—send your specifications for a tailored solution.
This field checklist explains how to troubleshoot temperature faults on a JINGCHENG electrically heated hose before replacing the assembly. It shows how to read the model code (for example JCH-200-16-B-3X220-P2-8) and match the sensor to the controller—Type J or Type K thermocouple, Ni120, PT100 (two-wire or three-wire) or PT1000. It then covers pin-table and connector checks, voltage and power (including PID controllers with SSR or thyristor output, and 2- or 3-channel control boxes), and installation mistakes that look like control failures: lateral twist, tight bends, cold routing and damaged jackets. A final eight-step checklist lists what to send with an inquiry.
