The monomer or prepolymer enters the mixing head in liquid state through the metering pump in a certain proportion for mixing. After the mixture is injected into the mold, it reacts rapidly in the mold, crosslinks and solidifies.

低壓灌注成型使用的材料主要是聚氨酯材料。通過改變材料的混合比，可以獲得不同的材料彈性模量，從而獲得所需的材料性能。固化后的材料具有類似于ABS、PP或PS的物理性能。該工藝適用于生產壁厚較大、壁厚不均勻的原型產品。

The materials used in low-pressure pouring molding are mainly polyurethane materials. By changing the mixing ratio of materials, different elastic modulus of materials can be obtained, so as to obtain the required material properties. The cured material has physical properties similar to ABS, PP or PS. The process is suitable for producing prototype products with large and uneven wall thickness.

低壓灌注成型可以生產出堅固、靈活、輕便的零件，并且易于進行表面處理。與典型的真空鑄造材料相比，它的材料制作時間比較短。注入模具中的混合物的粘度比熔融的熱塑性聚合物低得多，因此可以使用RIM技術加工大尺寸、輕量和薄壁的物品。這種輕薄的產品需要較小的夾緊力，因此需要的設備較小，投資成本低。

Low pressure injection molding can produce strong, flexible and lightweight parts, and it is easy to carry out surface treatment. Compared with typical vacuum casting materials, its material manufacturing time is relatively short. The viscosity of the mixture injected into the mold is much lower than that of molten thermoplastic polymer, so rim technology can be used to process large-size, light-weight and thin-walled articles. This light and thin product requires less clamping force, so it requires less equipment and low investment cost.
