現(xiàn)在的塑膠模具制造當中已有越來越多開始使用鈹銅模具材料，且出現(xiàn)不斷上升的趨勢，造成這一現(xiàn)象的原因是什么呢？跟隨小編一起來了解鈹銅在塑料模具上的運用，以及原因。

1.足夠的硬度和強度：在經(jīng)過很多次的試驗之后，工程師才能夠找出以及掌握鈹銅合金zui佳的沉淀析出的硬化條件以及zui佳工況還有鈹銅的彌撒特性（這一點是鈹銅合金以正式產(chǎn)品開始應用在市場的前奏）；鈹銅材料應用在塑膠模具之前是需要經(jīng)過多次輪回的試驗來zui終把zui佳的符合制造以及加工的物理特性和化學成分確定下來；理論與實踐的證明–鈹銅的硬度在hrc36-42時能夠達到適用于塑膠模具制造要求的硬度、強度、高的導熱率，機加工簡易方便、模具使用壽命長的特點以及節(jié)省開發(fā)生產(chǎn)周期等。

2.良好的導熱特性：鈹銅材料的導熱特性有利于控制塑料加工模具的溫度，也更容易控制成型周期，同時可以保證模具壁溫的均勻性；如果與鋼模相比，鈹銅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.
