About the working characteristics of the turntable foam injection molding machine production line

The Turntable Foam Injection Machine Production Line adopts a horizontal or vertical turntable structure, usually equipped with 4-6 mold stations, each station synchronously performs mold closing, injection molding, pressure holding, cooling, mold opening and other processes to form a continuous cycle production. The turntable drive system is positioned by servo motor or hydraulic control, and the error must be controlled within the standard to ensure the mold alignment accuracy.
The foaming process is synchronously controlled with the turntable rotation to ensure uniform gas distribution and avoid bubble collapse or uneven density. High-pressure injection is used in the injection stage, combined with a closed-loop temperature control system, and the melt temperature fluctuation range is controlled within ±1°C to prevent raw material degradation or insufficient filling.
The cooling stage switches to low-temperature mode (the mold temperature drops sharply to below 30°C), shortening the molding cycle by 20% and reducing the risk of product deformation.

During production, the mold is placed on the workstation of the turntable foaming injection molding machine production line, and the turntable rotates at the set beat to complete the processes of loading, foaming, curing, demoulding, etc. in sequence to realize the production of polyurethane foam products. The reduction motor is controlled by the frequency converter and rotates at a certain speed ratio. The mold is placed on the periphery of the turntable, and the mold temperature controller and gas storage tank are placed in the middle. Combined with a high-pressure foaming machine or a manipulator, efficient production is achieved. PLC combined with a touch screen is used to achieve precise control of parameters such as turntable speed, raw material metering, foaming time, and curing temperature. In addition, the introduction of advanced sensors and monitoring mechanisms has realized continuous real-time monitoring and fine adjustment of the production process, greatly improving the consistency and reliability of product quality. The implementation of the automated control system has achieved smooth conversion between various production modes, significantly improving the efficiency and adaptability of production.
