Phenolic Foam/Polyurethane Sandwich Panel Production Line

Introduction of the Equipment
Phenolic Foam/Polyurethane Sandwich Panel Production Line is a professional machine for manufacturing Sandwich Panels of which the core material is phenolic foam or polyurethane and of which both layers is embossed aluminium foil or colored steel. The thickness of sandwich panel is 20-200mm, the width 1200mm and the length according to customersí» request. The sandwich panels are used as the air ducts in Central air conditioning. The machine can used to make other insulation panel as long as the surface material is changed. The working principle of the machine is as below: mix the raw materials with a certain ration in a container and then pour the mixture on the interlayer of the sandwich panel. Then the raw materials has the chemistry reaction of foaming and solidifying. In the end the automatic tracking cutting machine cuts the panels into a certain length.

The Components and Its Function

The components include: the aluminium foil embossing machine, the raw material distributor, the aluminium foil/colored steel pre-heating installation, the material-baffling mechanism, the automatic tracking cutting machine, the roller supporters and brackets. All the components can be individually adjusted.

The Aluminium Foil Embossing Machine

The embossing machine include three parts: the charging unit, the embossing unit and the windin unit. It is used to emboss figures and logos under certain surface tension on the aluminium foil (Width: 1200mm, thickness: 0.08-0.12mm).
The Raw Material Distributor / The Raw Material Charging Unit
This device is installed at the forefront of the production line and the laminator. It can adjust the location and control the surface tension of the aluminum foil and the colored steel before entering the laminator.

The Aluminium Foil/Colored Steel Pre-heating Installation
Before entering the injection machine, the temperature of the aluminum foil or the colored steel must meet the requirement of the foaming technology of the PF or PU. And thermodynamic cycle device on the production line can control the temperature of the aluminum foil or colored steel.

The Material-baffling Mechanism
The material-baffling mechanism is used to stick Kraft paper to both sides of the lower aluminum foil before entering the injection machine. So there is a enclosed area between the upper aluminum foil and the lower one. With the Kratf paper, there will be no leakage of the raw materials when the machine is working.

The Reaction Injection Machine

The reaction injection machine is used to calculate the computation and mix of raw materials pro rata. In order to make the temperature of the raw materials meet the requirement of the foaming technology, the machine is equipped with heating, refrigerating and temperature control devices. In addition, People can control the pressure, the computation of the raw matrials by this machine. And the process of injection, cleaning and sweeping are automatically controlled. The equipment is equipped with three tanks, two for resin materials, one for curing agent material.

The Back-and-forth Injection Machine

This machine is used to apply the mixture on the lower aluminum foil or the colored steel. The injection head is drived by fluid drive, and its speed, moving frequency, transverse moving distance is adjustable.
