Research On The Qualification Ratio Improvement Of Gypsum Mold Casting In Huahong Company

In this developing age,informatization not only leading us to a convenient and intelligent life,but also changing our pursuit to fashion.Eyewear is a symbol of fashion as well as a kind of attitude to life.Nowadays eyewear should satisfy people both in function and their expectations to fashion.That exactly stimulates the development of casting and results in the new challenge of casting technology.This article aims at improving the qualification ratio of gypsum mold casting in component plant of Huahong glasses company and analyzes the reasons of low qualification ratio by TQM,process optimization theory and related tools.It points out that product structure design,process to be optimized and quality inspection to be improved cause the low qualification ratio.Based on the above reasons,this article proposes solutions in three aspects for enhancing the qualification ratio of gypsum mold casting.Firstly,consider chamfer design at the design phase and optimize the running gate design.Secondly redesign the cutting tools and optimize the barreling process to reduce the scratch in terms of production working flow.Optimize the casting system,improve the anti-static process and reselect decontamination tools to reduce the defect of surface crack,porosity and scratch.Thirdly,optimize inspection system to decrease the misjudge and undetected from quality people.In the end,this article evaluates the results of enhancing qualification ratio of gypsum mold casting.As a foundational process in industrial development,casting has its long history,but still there is space for its quality and process improvement,especially for gypsum mold casting.This article focuses on the research of casting qualification ratio in component plant to summary some solutions to process optimization and quality inspection.It would be a lesson for casting continuous development and optimization.
