PU Sandwich Panel Production Line

Description
The PU sandwich panel production line is used to manufacture polyurethane or phenol laminated sandwich panels with color steel facings. The continuous production line for rigid poly foam laminated panels with color steel facings is a type of specialized equipment used for producing color steel sided sandwich panels with the middle layer of anti combustion polyurethane, polyisocyanurate or phenolic foam plastic. The thickness of the produced sandwich panel ranges from 0 to 10 mm, the width between 750 to 1000 mm and the length on request.
The PU sandwich panel production line is used to make wall panels for steel structures and roof panels. It can also be used to make various types of insulation panels if replacing the facing sheet. Its operation principle iss as follows: rigid poly foam raw materials, according to a certain blending ratio, are delivered into mixing head to agitate through metering pump unit on the injection machine and then uniformly injected onto the bottom facing sheet of sandwich panel. After the injection, the bottom facing sheet moves toward the double belt conveyors together with panels top facing sheet. Between the two conveyors, injected raw material is foamed and hardened into shape. At the end of the line, the formed sandwich panel is cut into preset length by an automatic tracking cutter.

Equipment Maintenance
Meticulous daily maintenance plays an important part in extending the sandwich panel production line's operation time and the quality of the rolling plank. The following steps should be part of the machine's daily production and usage routine.
1. Regularly lubricate the outside parts of the sandwich panel production line, i.e., driving chain, etc.
2. Regularly wipe the surface of roller, particularly when working outside. If you do not use the machine a long time of time, you should daub lube in the roller surface. Make sure you clean it the next time you use the machine.
3. If the sandwich panel production line is not used for a long period of time, make sure you cover it with plastic or cloth. Avoid getting rain on the machine or the machine becoming damp, especially the electric control box.
4. Make sure the cutting system is lubricated when necessary.
5. Check the hydraulic station often and the oil quantity of the deceleration machines. Add more oil if the oil level is low.
6. Check the electric appliances box and every leads conjunction circumstance of the sandwich panel production line. Dust the machine often.

Packaging
The sandwich panel production line is wrapped and covered with film making the package seaworthy. The legs of the machine are fixed with angle steel and heavy screws.
