Polyurethane sandwich panel line (Continuous)

Polyurethane Sandwich Panel Line

PU sandwich panel line- 3D

Polyurethane Sandwich Panel Line is the automation equipment that can continuously and efficiently produce polyurethane sandwich panels of exquisite and diverse shapes. This Sandwich panel line has the advantages such as high durability, easy management, technology equivalent to those of advanced European companies and relatively competitive price, and it is the excellent facility that has been exported to Europe, Asia, Middle East, Russia and so forth as well as domestic market and is well received from customers.

Our PU sandwich panel has high strength and durability of insulating ability. In addition, we use the PIR (Poly Isocyanurate) which it has the resistance to flame so the panel has the high resistance to flame. Also HCFC-14b the blowing unit as well as the Pentane the eco-friendly material will make more safety and better environment as it’s the “GREEN” unit.

Polyurethane Sandwich Panel Line consists of Un-coiler that inputs and releases coil, Roll Forming Unit that makes shape of coil, PU Forming Unit that sprays PU solution, Laminating Unit that makes the shape of sandwich panel, Panel Cutting Unit that cuts the fabricated sandwich panel, Cooling Conveyor Unit that finishes products hardening the cut panel sufficiently at intervals, Auto Stacking Unit that loads the finished panels, and Panel Packing Unit that packs the loaded panels with plastic wrap and discharge them.



Un-coiler is a device that inputs steel coil to the upper and lower parts of sandwich panel to feed it stably.
The mandrel type operated automatically by a hydraulic and it’s convenient to control and sophisticated. 2+2 system production equipment unit doesn’t need to stop to load the new coil set, which it helps to continue to produce high capacity of panels.

un-coiler-01 un-coiler-02

Roll forming machine

It is a device that continuously gives shape to sandwich panel as steel coil fed from Un-coiler is engaged between the upper and lower sections of a metal roller.
Usually it makes the beautiful and delicate shape of variety wall and roof type panel. It designed in cassette type and rail way wheel type to easily change to make different shapes.


PU foaming mahcine

It consists of the nozzle and pump that spray polyurethane solution, a tank that stores solution, various catalysts and gas, and a traverse that enables to spray PU solution evenly, and the device is designed considering high precision and the reliability of maintenance. A convenient control panel is equipped with for users’ easy control of various data required for foaming process.
It equipped with a convenient control panel (Control panel) so that you can easily adjust the various data required for the firing process.


Laminating unit

It is a device that makes the shape of sandwich panel applying constant pressure and heat to the upper and lower steel plate foamed with polyurethane.
It designed in perfect structure that has a stiffness and durability and as well as the side blocks to enable the rapid of product replacement.


Panel cutting unit

A device that cuts sandwich panel fabricated at Laminating Unit to the length desired by users using a band saw.
Different types cutting such as wheel cutting and band saw cutting has developed to correspond for the customer’s needs.


Cooling conveyor unit

In case that a certain time is required till completely hardening since polyurethane sandwich panel is thick, Cooling Conveyer enables to allow sufficient hardening time prior to stacking and packing panels.


Auto stacking unit

As is a device that automatically stacks the finished panels, the quantity desired by users can be loaded continuously by loading pattern of vacuum suction plates or lift conveyor And in case of roofing material, cross stacking is available, if necessary.


Panel packing unit

A device that packs panels loaded at Auto Stacking Unit with plastic wrap on 4 sides or 6 sides and discharges them.
Applying pallet systems to insert the EPS block automatically and it makes handy for cargo transportation and storage the panels.
