Discontinuous PU Sandwich Panel Production Line Manufacturing

Discontinuous 3+3 PU Sandwich Panel

Production Line

The 3+3 discontinuous PU sandwich panel production line is designed to produce high-quality polyurethane (PU) sandwich panels with enhanced insulation properties. The "3+3" refers to a production method where three panels are pressed simultaneously on each side, increasing production efficiency.

This discontinuous production line is designed for producing PU sandwich panel according to customer’s requirement. The line mainly consists of roll forming machine(roof&wall), fully automatic panel lamination mold, two components high pressure foaming system.

5Ton Hydraulic Decoiler With Car

Decoiling System is to feed the color steel sheet to roll forming machine. The capacity of the decoiler will be decided by supplied the coil weight.

Type of decoiling	Motorized active
Max loading capacity	≤5t
Suitable coil ID	φ508mm/φ610mm
Suitable material width	1250mm

Roll Forming System

The number of roll forming machines depends on numbers of finished panels customer needs.

Guiding Device

Adopting guiding bar and sliding block to control the width and position of the steel sheet. The sheet is guided in the correct position and runs to the roll forming equipment. The transverse position of the guiding device can be adjusted by screw.

Roll Forming Device

Forming roller adopts No.45 steel, surface polishing treatment and hard chrome plating.Roller shaft adopt No.45 steel after quenching and tempering process. The support structure mode is column.

Fully Automatic Panel Lamination Mold

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.

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.

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.

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.

Key Features

Manual Operation

Operators control the production steps, making it suitable for small or irregularly shaped panels.

Flexibility

Can produce panels with various thicknesses, lengths, and foam systems.

Lower Investment

Compared to continuous lines, discontinuous systems require lower capital, making them ideal for companies with limited production needs.
