请大虾们指教下面翻译的不妥之处,谢谢!
Injection molding is a cyclic process of forming plastic into a desired shape by forcing the material under pressure into a cavity. The shaping is achieved by cooling (thermoplastics) or by a chemical reaction (thermosets). It is one of the most common and versatile operations for mass production of complex plastics parts with excellent dimensional tolerance. It requires minimal or no finishing or assembly operations. In addition to thermoplastics and thermosets, the process is being extended to such materials as fibers, ceramics, and powdered metals, with polymers as binders.
注塑模具是使物料在强大压力下溶解后进入模具型腔,从而使流动的塑料组成我们想要的形状,其过程是可循环的。其原理是利用冷却(热塑性材料)或者化学反应(热固性塑料)来成型。它是一种很常见而又复杂的操作方法,可以用它来生产形状复杂但是尺寸精度要求很高的塑料制品。它是一个需要很细心、无止境的、集思广益的操作工程。除去热塑性和热固性塑料之外,注塑模具技术的应用已经延伸到光纤、陶瓷、粉末金属这些高分子材料领域。 |
