JYJ-Strip
The Hot Melt Butyl Rubber Sealant Coating Machine Extruder for Automotive (Brand: JIAYUAN, Model: JYJ-II) is a double-sided butyl rubber coating system designed and manufactured by Ruian City Jiayuan Machinery Co., Ltd. It applies molten butyl rubber sealant onto carrier substrates for the production of automotive-grade sealing tapes, waterproof strips, vibration-damping materials, and sound insulation components.
The machine uses hot melt extrusion technology to deliver butyl rubber sealant at controlled temperature and pressure onto substrates including aluminum foil, PET film, PE film, nonwoven fabrics, and release liners. The system is equipped with an intelligent PLC control system, accurate temperature regulation, and stable pressure control to maintain consistent coating output during continuous production runs.
The PLC-controlled system regulates extrusion temperature, pressure, and coating weight to maintain uniform coating thickness across the 200–500mm coating width. Temperature zones are independently controlled to keep butyl rubber within the required processing viscosity range.
The extruder supports double-sided coating on aluminum foil, PET/PE films, nonwoven fabrics, and composite structures. This capability enables the production of various automotive sealing tape designs, including carrier-reinforced and free-film constructions, on one system.
The hot melt butyl rubber process operates without solvents, reducing VOC emissions compared with solvent-based coating methods. This characteristic aligns the production line with automotive industry environmental requirements for manufacturing facilities.
Independent unwinding (1000mm diameter) and rewinding (700mm diameter) stations, combined with automatic tension control, maintain consistent web handling at coating speeds of 1–30m/min. The system reduces operator dependency and improves production consistency across shifts.
The machine is built with a robust frame designed for continuous high-load operation in industrial manufacturing environments. The low-wear extruder design and durable components reduce maintenance frequency and support extended production runs.

This coating machine produces sealing products for automotive door seals, windshield bonding, roof waterproofing, wire harness sealing, and NVH (noise, vibration, harshness) control systems. Business buyers in the automotive OEM supply chain and aftermarket sealing product manufacturing use this equipment to meet vehicle industry quality standards.
The machine supports a coating thickness range of 0.5–5mm, adjustable via the PLC control system based on the product specification. Thickness settings should be confirmed with the manufacturer for specific sealant formulations.
Yes. The JYJ-II model is configured as a double-sided butyl rubber coating machine, allowing sealant application on both sides of the carrier substrate in a single pass.
Customization is supported based on customer requirements, including coating width adjustments, additional unwinding/rewinding stations, specialized die head configurations, and integration with existing production lines. Customers should provide their production specifications for a tailored configuration quote.
