摘要

快速模具可以制造聚合物模具刀片，减少对减法制造和模具加热的依赖。本研究比较了微注射成型中的快速聚合物和金属模具，重点是机械性能和能源效率。微拉伸杆设计采用了聚合物模具和铝制模具。在μ-IM机器上对两种模具进行了测试，监测循环过程中的能量消耗。研究表明：(i)聚合物模具在金属的6.4%内实现拉伸性能，（ii）每次成型可节省17.6%的能源，（iii）快速工具可以替代金属生产微型产品，提供能源效率，缩短产品迭代的交货时间。

Rapid tooling: comparative analysis of mechanical properties and energy efficiency in micro-injection mouldings using polymer and metal moulds

Rapid tooling enables the fabrication of polymer mould inserts, reducing reliance on subtractive manufacturing and mould heating. This study compares rapid polymer and metal tooling in micro-injection moulding, focusing on mechanical properties and energy efficiency. A micro-tensile bar design was used polymer mould and an aluminium counterpart. Both moulds were tested on a μ-IM machine, monitoring energy consumption during cycles. The study showed: (i) Polymer tooling achieves tensile properties within 6.4% of metal, (ii) up to 17.6% energy savings per moulding, (iii) rapid tools can replace metal for micro-products, offering energy efficiency, reduced lead times for product iterations.
