Abstract

Obtaining a good surface finish on casting is challenging and depends on the dimension of the sand particles and the processing method of the mold. Evolving modern trends in mould and core production as a binder jetting technology is an option and it is more than desirable to evaluate and remove any possible negative effects. The aim of this study is to compare the influence of furan no-bake technology and 3D printing method on the surface quality of cores and cavities formed in aluminium alloy castings. In addition to the sieve analysis and mechanical properties of the moulding mixtures, the roughness (Ra, Rz) of the cores and resulting casting surfaces of individual samples were compared in this study.

摘要

在铸件上获得良好的表面光洁度具有挑战性，并且取决于砂粒的尺寸和模具的加工方法。作为一种粘结剂喷射技术，模具和型芯生产的现代发展趋势是一种选择，评估并消除任何可能的负面影响是非常必要的。本研究的目的是比较呋喃自硬技术和3D打印方法对铝合金铸件中形成的型芯和型腔表面质量的影响。除了对造型混合料进行筛分分析和力学性能测试外，本研究还比较了各个样品的型芯粗糙度（Ra、Rz）以及最终铸件表面的粗糙度。
