It is used for making large PU products such as highly-elastic foam mattress, cubic thermoplastic foam ceilings for vehicle use, etc.
Low-pressure reaction injection machine of large flowrate developed on our own is a kind of low-pressure injection equipment with the throughput as much as 6, 000 gms/sec, which is suitable for making large block-type flexible, half-rigid, and rigid foam products and is widely used in the production of automobiles, building and industries needing insulating materials.
　　Using such machine to produce large foam plastic is accurate in metering, uniform in foaming and stable in quality and can completely substitute manual mixing and foaming method, greatly increasing the working efficiency.
