【摘要】 本文简要地介绍了利用石膏混合料造型,在真空条件下浇注,压力作用下结晶,快速制造铝合金复杂模具型腔的工艺办法。对石膏特性、灌浆、硬化机理、脱蜡、焙烧、浇注和压力对结晶过程的影响作了较进一步的分析。更多还原

【Abstract】 In this paper,a last technique tor making complex aluminium alloy eavi- ty,which was casted under vacuum and crystallized under pressure,was intro- duced briefly.The mixture plaster was used for making model.It takes further steps to analyses influence of character of plaster,grouting,harder mechanism,de- waxing,roast,casting and pressure on crystal process.更多还原
