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 it uses both layers embossed with
aluminum foil, colored steel stainless steel, plywood or plastic
plate.
The thickness capacity of sandwiched panels our machine can produce
are 20-200mm, width of 1200mm and the length can be customized according
to customers’ request. Our production line machine can be
used to make other insulation panel as long as the surface material
is changed.
Working principle of our production line machine
Raw materials are initially mixed at a specified ratio in the reacting tank installed above the production line machine. Then its injects the pre mixed resin formulas into the interlayer of the sandwich panel, Due to the resins chemical formula it reacts as a foaming agent and solidifies the inter layers with the core material. The sandwich formed panels will then go through a heating process to adhere inter layers and the core material to produce and assure a well solidify panels as a finished product.
The final product that has been produced as per customer’s requirement with the specified core and crust materials will then be cut to size according to the required lengths on the machine’s automatic track cutting device.
The components of the production line
• Aluminum foil embossing machine
• Raw/core material injection/distribution
• Heating oven as well as refrigerating systems
• Automatic track cutting machine
• Roller, supporters and brackets
All listed parts of the machines are capable of individual adjustment.
The Aluminium Foil Embossing Machine
 |
The embossing machine includes three parts: the charging unit, the embossing unit and the winding unit. It is used to emboss figures and logos under certain surface tension
on the aluminum foil with a customizable capacity of Width’s
(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 or 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 (PF or PU). Only then the thermodynamic cycle device on the production line can control the temperature of the aluminum foil or colored steel accordingly.
The Material-Baffling Mechanism
The material-baffling mechanism is used to stick Kraft paper to both sides of the upper & lower aluminum foil before entering the injection machine. This method will insure there is an enclosed area between the upper & lower aluminum foil. The Kraft paper will guaranty there will be no leakage of the raw/core materials when the machine is working.
The Reaction Injection Machine
In addition, operating technicians can control the pressure, the computation of the raw materials using this part of the machine. The process of injection, cleaning and sweeping are automatically controlled. The equipment is equipped with three tanks, two for resin, one for curing agent.
