仪器外壳成型新工艺-反应注射成型技术解析

摘要

Means for reaction injection molding of a variety of organic synthetic polymer materials by changing the chemical structure of the material, a method using physical changes (such as temperature, shear and high weight ratio) to produce a variety of different properties and uses of the product. Originated in the polyurethane reaction injection molding of plastic, with the advancement of technology, the process is also extended to the processing of a variety of materials.%反应注射成型是指针对多种有机合成的高分子材料，通过改变材料的化学结构，采用物理变化的方法（如温度、重量比例和高剪切等）来生产各种不同性能和用途的产品。反应注射成型起源于聚氨酯塑料，随着工艺技术的进步，该工艺也扩展到了多种材料的加工中。
