Automoibile Seat Foaming Production Line
Reliable Automobile Seat Manufacturing
Our state-of-the-art HAL Ground Rail Oval Type Polyurethane Foaming Automatic Production Line is designed for high-volume production of molded foam products, including automobile seats. The production line operates with a level of precision, efficiency, and consistency due to the two-component high-pressure foaming system, an automatic pouring robot, and an automatic spray robot for releasing mold agents. The system’s closed-loop vertical conveyor and multiple station workstations are designed for in-line production and are optimal for fully automated industrial applications.

Our engineers now offer tailored, innovative production systems to meet your specified production demands.
Advanced Polyurethane Foaming Solution for Automotive Applications
The HAL Ground Rail Oval Type Polyurethane Foaming Automatic Production Line is an industry-leading facility for the continuous polymerization of molded polyurethane products for the automotive industry and includes automobile seats, headrests, and backrests. Featuring a two-component, high-pressure foaming system, robotic pourers, and mold release automation, the production line is designed for speed, quality and stability.
How it works:
The two-component high-pressure foaming system consists of one polyether polyol (POLY.) tank and one polyisocyanate (ISO.) tank. A variable-frequency motor drives each of the two metering units and operates a high-pressure metering pump. It is possible to configure the system for open-loop or closed-loop control to optimize performance for the production of polyurethane molded foam.
The circular system consists of multiple stations and an oval shape, designed to allow inline production of various foam molds. Mold temperature controllers and air compressors are set along the conveyor line for efficient mold heating. The drive system consists of a speed-regulated gear motor with a variable frequency drive (VFD) that moves the mold trolleys along the conveyor. Pneumatic cylinders handle mold opening and closing, and mold locking is done by lifting the cylinders. A hot-water-circulation system ensures the mold temperature remains constant.
A PLC system controls all stages of production. The system is responsible for automatic feeding, spraying release agents, pouring material, changing ratios, opening and closing the mold, heating and curing, and manually removing the product.
