现在的塑胶模具制造当中已有越来越多开始使用铍铜模具材料，且出现不断上升的趋势，造成这一现象的原因是什么呢？跟随小编一起来了解铍铜在塑料模具上的运用，以及原因。

1.足够的硬度和强度：在经过很多次的试验之后，工程师才能够找出以及掌握铍铜合金zui佳的沉淀析出的硬化条件以及zui佳工况还有铍铜的弥撒特性（这一点是铍铜合金以正式产品开始应用在市场的前奏）；铍铜材料应用在塑胶模具之前是需要经过多次轮回的试验来zui终把zui佳的符合制造以及加工的物理特性和化学成分确定下来；理论与实践的证明–铍铜的硬度在hrc36-42时能够达到适用于塑胶模具制造要求的硬度、强度、高的导热率，机加工简易方便、模具使用寿命长的特点以及节省开发生产周期等。

2.良好的导热特性：铍铜材料的导热特性有利于控制塑料加工模具的温度，也更容易控制成型周期，同时可以保证模具壁温的均匀性；如果与钢模相比，铍铜的成型周期要小的多

column. The right hand column with our name is either identical in composition or a fully replaceable alloy with only minor

differences. The column in the middle states the norm and its country of origin.

With no marks in front of LM’s alloy = alloy is identical, with this sign “~” = alloy is very similar, fully replaceable.
