Our PU sandwich panel machine is the forming equipment that integrates advanced mechanical, chemical, electrical, hydraulic, and pneumatic technologies. It has earned five patents of utility model. Due to its high efficiency and simple operation, this forming machine is widely used in the construction of steel structure enclosures, cold storages, and mobile buildings. In order to satisfy various customer requirements, we design and manufacture PU sandwich panel lines in different specs, models and configurations.

Detailed description
foaming machine
(1) Machine frame
As one of the stressed members of foaming machine, the frame of machine is welded by high-quality steel. Distressing treatment helps machine fame to be safe and artistic.
(2) Joist steel
During the period of foam curing, hydraulic system needs to provide loading board strong clamping force to overcome foaming force. If the force is directly placed on the board, it would get distorted and eventually destroy the foaming machine. To avoid above condition, we use joist steel to weld some work pieces which corresponds with loading board. In this way, clamping force can be placed equally on the board. Besides, joist steel has high stability during processing and transporting.
(3) Rail
Appropriate rail need to be prepared when the loading board is getting in and out of the main machine, meanwhile, the rail needs to meet the clamping space requirement. The rail is same with the external rail.
(4) Synchronizing mechanism
Different phenomenon will be caused when numerous hydraulic cylinders working together, so we use an economical and practical method to make sure oil-cylinder synchronization and avoid damage as well. We also give full consideration to the convenience and safely while installing and using.
Hydraulic system
Hydraulic system automatically compensates pressure, low pressure driving, and high pressure maintaining pattern fully saves space and energy.
Heating system
Water pipe circulation loop is contained in each loading board, so we can use hot-water to heat each board separately to ensure the curing temperature.
(1) Temperature controller
We use water heating and PID temperature control method which can supply enough hot water accordingly. The total power is 72KW.
(2) Heating pipe
Temperature resistance rubber tube connects temperature controller and loading machine, drag chain protects the surface to avoid tube damage.
