AI Technical Summary
In the existing technology, the quality of ceramic substrate casting is relatively low, mainly due to inconsistent slurry parameters leading to unstable dry film thickness. The existing process lacks real-time closed-loop feedback and dynamic adjustment, resulting in unstable product quality.
By establishing a mathematical model with multiple parameters, the degassing device and the casting device are linked, the viscosity of the slurry is obtained in real time and the height of the scraper is dynamically adjusted, and the casting process parameters are automatically adjusted. This includes establishing a relationship model between the viscosity, vacuum degree, shear rate and temperature of the slurry in the degassing tank, so as to ensure that the viscosity of the slurry is stable during the casting process.
It enables automated adjustment of casting process parameters, solves the problem of unstable casting sheet thickness caused by viscosity fluctuations, improves product thickness uniformity and quality stability, increases production efficiency, and reduces quality fluctuations caused by manual intervention.
