A and B components of the raw liquid, after accurate ratio and high-speed mixing, by two high-precision metering pumps, A and B components of the liquid to the mixing head. After high speed strong stirring, make the material liquid even and eject, form the required product. From the power classification can be divided into: high speed impeller type, high pressure air type, drum wind low pressure type. A complete small polyurethane foaming machine consists of the following systems: material flow system, metering system, gas circuit system, heating system, cleaning system, mixing device.


As long as the properties of polyurethane components (isocyanate components and polyether polyols components) meet the requirements of the formula. Through polyurethane foaming machine can produce uniform, qualified foam products. It is based on polyether polyol and polyisocyanate in the presence of foaming agents, catalysts, emulsifiers and other chemical additives, through chemical reaction foam and made of plastic foam.
