Reviews
PU Sandwich Panel Machine is a special machine for producing the different kinds of sandwich panels.
It mainly consists of the following parts: uncoiling system, roll forming machine, pre heating oven, foam injection machine, double belt laminator, double belt laminator heating system, cutting system, cooling system, stacking system, packing system, etc.
The product of Rockwool Sandwich Panel Machine is a new type building material, which has the function such as good flame retarding, keep warm, heat insulation, sound insulation, waterproof, handiness, environmental protection and so on. It is widely applied in protection and decoration of outside wall for tall buildings and factory.
Special sizes of sandwich panel can be designed in our company. The machine can be customized based on the customer’s specific technical requirements.
PU Sandwich Panel Machine can do roof sandwich panel, wall sandwich panel. Special sizes of profiles can be designed in our company.

High Precision Roll Forming System
Roller Material adopts High grade No.45 steel with quenched treatment, with digital-controlled procession, painted with hard chrome. Shaft Material adopts high grade No.45 carbon steel, which can improve the integrated mechanic feature of the shaft. The roller shafts adopt standing column type.
The roll forming machine can be move in or out of the production line to switch different profile.
Advanced Foam Injection Machine
The foam machine is injecting the liquid material continuously while the production line is working. The raw material is the foam is Mdi, Polyol, catalyst and foam agent( pentane or 141b). The foam has stable density: 36～45 kg/m3.
High Quality Double belt Laminator
Double belt Laminator is mainly used to overcome the expansibility of foaming and make it solid, and it's decided by panel thickness and production speed. Side belt is overcome horizontal expansion and it's decided by the width of panel and guiding to the panels. As active running mode, double belt laminator can avoid panel deformation and scratch and to ensure panels quality.
Continuous Cutting System
Continuous Cutting System main function is used to cut the required product. It will cut the product when product’s length reaches the setting length in PLC, which measured by measuring encoder without stopping machine. In this way the machine can run continuously during the cutting, and absorb the waste foam and dusts at the same time.
Packaging Details
1. Seventeen *40GP containers for loading one set of the machine. (the container quantity is decided by the spec. of the machine.)
2. The whole Wiped Anti Rust Oil, PLC controller covered by foam film;
3. Spare parts and some small parts packed in wooden box;
4. All Components Fixed by steel wire with Container. Suitable for long time sea shipping.
