Problems solved by technology

The quality of polyurethane products is directly related to the mixing uniformity of polyurethane material A and material B. At the same time, when mixing polyurethane raw materials, it is necessary to ensure that a sufficient amount of gas is mixed into the raw materials and the gas is evenly distributed in the polyurethane raw materials; but the traditional The polyurethane foaming machine uses a metering pump to drive polyurethane material A and material B into the mixing head at a set ratio and flow rate. When the one-way valve of the mixing head is opened, material A and material B are mixed in the mixing head, and the compressed gas blows out the mixed material. The head is injected into the mold to produce the finished product, which makes the polyurethane foaming process extremely unstable, resulting in poor molding accuracy of the produced polyurethane foam material, and it is difficult to produce high-quality finished products
