In reaction-injection moldinga mixture of two or more reactive fluids is forced under high pressure into the mold cavity.Chemical reactions take place in the mold rapidly and the polymer solidifies.Various fibers such as glass,graphite,or boron may also be used to reinforce the materials.Structural foams are also produced by a similar methodusing an inert gasand resin mixture.The product consists of a rigid cellular(closed-cell)structure with a continuous solid skin as muchas 0.080 in.(2mm)in thickness.There are several methods for forming structural foams with density reductions as much as 40% from the solid structure.Because stiffness is proportional to the third power of the thickness of a part,for the same weight of material used,cellular structures are stiffer than solid plastics or metals.

在反应注射成型所夹杂的两个或两个以上的接触过程中，被迫在高压下进入模具cavity.chemical反应发生在模具迅速和聚合物solidifies.various纤维如玻璃，石墨，或硼可能也可以用来加强materials.structural泡沫也产生类似的方法利用惰性气体和树脂mixture.the产品构成的一个硬性蜂窝的结构与连续性固皮肤作为留言Muchas 0.080英寸（ 2毫米），在thickness.there有几种方法，形成结构性的泡沫密度减少了四成之多，从固体structure.because刚度成正比第三力量厚度的一部分，为同样重量的使用材料，蜂窝结构更为严厉的比硬塑料或金属。
