Rotary Car Seat Production Line
Rotary production line is arranged in a horizontal ground rotary structure, which can meet the needs of foaming molds of various sizes, and a variety of products can be produced online in mixed lines. The production line uses five 0.75KW motor reduction motors to drive the overall movement of the line body. The running speed of the line body is adjustable with variable frequency, making it easy to adjust the production rhythm. The mold temperature controller and mold base control box for mold heating on the production line are evenly placed on the mold carrying trolley. The power electricity is introduced using an annular brush (slip ring), and the air source is introduced using a slip ring, and is passed through the pipeline to each trolley on the line body. In order to facilitate mold change and maintenance, the temperature-controlled water and compressed air production lines between workstations are all connected with union joints to achieve rapid mold change.
Working Principle Of Rotary Car Seat Production Line
All trolleys are connected by front and rear tie rods, track plate positioning, reducer drive, automatic recognition of station number, the trolley runs to the mold opening guide rail and the upper mold automatically rises, automatically opens the mold to pick up parts, clears the bubbles, and manually sprays the release agent. Then run to the pouring station to pour the raw materials. The rail will slide down and open to automatically close the mold. The air bag lifts up and locks the mold to begin maturation. Run to the mold opening station. The air bag is exhausted. The upper mold enters the mold opening guide rail, automatically opens the mold, and completes a cycle of work.

Polyurethane Car Seat Molds
Of Rotary Car Seat Production Line
Polyurethane car seat molds are precision-engineered tools used in the production of automotive seat cushions and backrests through foam-in-place technology. These molds are typically constructed from high-strength aluminum or steel, designed to withstand high pressures and repeated thermal cycles during the foaming process.
Each mold is custom-designed to match the ergonomic shape and comfort specifications of specific vehicle models. Integrated with advanced features such as automatic mold temperature control, robotic demolding systems, and in-mold release agent spraying, these molds ensure consistent foam density, perfect surface finish, and dimensional accuracy.
By combining durability, precision, and automation, polyurethane seat molds play a critical role in achieving high-quality, comfortable, and safety-compliant seating systems for modern vehicles.
Transmission
Of Rotary Car Seat Production Line
5 reducer motors are installed on 5 trolleys, and are driven by two-level reduction to achieve circular continuous movement along the ground guide rails.
The line speed is driven by a variable frequency closed-loop control motor to ensure that the cycle production line speed is adjustable from 10 to 25 minutes per cycle, according to the cycle time in automatic control mode.
The linear speed of the pouring area can automatically adjust the running speed of the mold base in the pouring area according to the speed required by the mold base process.
Ground Rail And Auxiliary Rail
Of Rotary Car Seat Production Line
The ground rail is used to support the formwork trolley and the foam mold. It is connected to the ground using expansion bolts. The ground rail is divided into two parts: straight rail and semi-circular rail. It is made of 10mm and 16mm wear-resistant steel plates.
Pneumatic System
Of Rotary Car Seat Production Line
The line body adopts centralized air supply, and the loop line and mold temperature controller are supplied through the electric rail power supply. The mold base air bag air source is provided, and the air source is connected to the ring line through a hose to ensure that the mold base top mold air source is provided.
The power supply for the cable body is located outside the cable body for easy maintenance.”
Introduce the air path to the air bag to supply air for mold locking, and use different models of quick-connect connections. Each trolley and airbag have one manual ball valve and one quick connector.
Mold temperature controller
Of Rotary Car Seat Production Line
3 mold temperature controllers (24kw) with water temperatures of 30-95°C are installed on 3 mold-carrying trolleys and move with the production line. Each mold temperature machine controls the mold temperature on 8 to 9 mold-carrying trolleys at a constant temperature. The electric heating exchange system realizes closed cycle constant temperature regulation of the medium water. The mold temperature controller has timed start/water shortage/overload/overcurrent/phase loss protection functions. After reaching the set temperature, a temperature control device reduces the impact current.
Robotic Arm
Of Rotary Car Seat Production Line
The robot arm is equipped with high-precision servo motors and intelligent control systems, with excellent repeatability and accuracy, which can significantly reduce human errors and ensure consistent product quality. Its flexibility enables it to be easily reprogrammed for different seat models, making it an ideal choice for mass production and customized production. The robot arm integrates sensors and safety systems, which not only improves operational safety, but also helps reduce labor costs, optimize cycle time and improve overall production line efficiency.
