With the advancement of society, the new-energy vehicle industry has emerged as a rapidly growing sector. Given the substantial demand for automotive products, we have developed high-pressure and low-pressure foam machines, along with corresponding automated production lines, to meet these needs and provide tailored solutions for different product requirements. Below are some examples of our automated production line solutions.

　　 1. Fully Automatic Disc Production Line

　　This is a fully automated, intelligent piece of equipment independently developed by Lingxin, suitable for foam production across a wide range of product types. It operates at a constant speed, with both the operating speed and production takt time being continuously adjustable; it is equipped with a parking brake and an overload protection system. The rotary table is fitted with power and compressed-air supply systems and is designed to work in tandem with mold frames, foam machines, mold temperature controllers, robotic arms, electrical control systems, and other equipment to form a complete foam-production line—ideal for high-volume, low-variety batch production. It is well-suited for manufacturing automotive seats, motorcycle seat cushions, household goods, furniture foam, and similar products, enabling efficient, precise production with high output and reduced labor requirements. Its modular design and high-end configuration ensure stable operation and easy maintenance.

　 　2. Fully Automatic Rail-Guided Circular Production Line

　　This is a fully automated, intelligent production line developed in-house by Lingxin, which is seamlessly integrated with mold frames, foam machines, mold temperature controllers, robotic arms, electrical control systems, and other equipment to form a complete foam-production line. It is suitable for manufacturing products such as automotive seats, interior and exterior trim components, new-energy vehicle assemblies, locomotive seat cushions, household goods, and furniture foam, enabling efficient, precise production with high output and reduced labor requirements. Its modular design and high-end configuration ensure stable operation and easy maintenance. The system has minimal space requirements and can be customized to fit the available floor length, while the arrangement of mold stations offers flexible configuration.

　 　3. Multi-head high-pressure machine workstation production line

　　A multi-head high-pressure machine workstation production line, equipped with a multi-head high-pressure foaming unit, hydraulic or pneumatic mold-clamping stations, robotic arms, and other auxiliary equipment, enables the mixing head to be securely mounted at the mold station or directly on the robotic arm for injection molding operations. This production line is primarily used for manufacturing large-scale automotive interior and exterior trim components, major automotive assembly parts, vehicle front and rear body panels, automotive floor mats, and oversized furniture items, in conjunction with large fixed mold frames. It features high efficiency, low-risk operation, and flexible layout of production stations.

　 　4. Integrated PIP Production Line for Automotive Headrests

　　The equipment consists of a frame, material storage system, filtration system, metering system, hydraulic system, temperature control system, heat exchange system, mixing system, electrical control system, piping system, and replenishment system. When used in conjunction with a polyurethane foaming machine, the production line operates in an intermittent mode driven by a cam indexer powered by a reducer. The cam indexer is mounted at the center of the rotary table, with the table’s speed controlled by a variable-frequency drive. Starting and braking are smooth, rotation is seamless and free of abnormal noise, and the cycle time for one complete revolution of the rotary table can be adjusted between 70 and 100 seconds.

　　An automatic mold identification system is installed on the production line. This system transmits the mold frame number via a communication cable to the foaming machine, which then performs pouring operations based on the received pour number, thereby preventing operators from misidentifying workstation numbers. In the event of a mold frame malfunction, pouring for that specific mold frame can be manually canceled.

　　The equipment features both manual and automatic modes; the manual mode is primarily used for commissioning, while the automatic mode is selected under normal operating conditions. In automatic mode, the rotary table operates in an intermittent cycle, with a customizable production takt time of 8 to 15 seconds per station. After each station rotation, the table automatically stops at the designated position to perform various operations and casting tasks. The operating speed is controllable and can be set via the human–machine interface. Due to the intermittent operation of the rotary table, its repeat positioning accuracy is maintained within ±0.5 mm.

　　The foregoing represents a selection of solutions we have provided to clients in the automotive industry. We are capable of delivering tailored, end-to-end polyurethane equipment solutions that precisely meet each client’s specific production requirements.
