Material selection for injection molds of thick-walled PP-R parts: experimental comparison of conventional 316L steel, CuBe alloy, and selective laser melting with conformal cooling: thermal performance, part quality, and financial viability
本研究通过实验证明,对于厚壁 PP-R 注塑成型,传统机械加工的铜铍合金模具在所有经济指标上均优于具有共形冷却功能的选择性激光熔融(SLM)模具,尽管初始投资较高,但其在缩短周期时间和节省成本方面表现更佳,同时两种先进概念均能成功生产出符合功能鉴定标准的产品。
