结合适当的喷涂工艺

使铝合金轮毂低压铸造用保温涂料的使用效果得到明显改善

提高了轮毂成品率

降低了生产成本

有效提高了生产效率。

Abstract

The existing problems of heat insulating die coating for low-pressure casting aluminum alloy wheels were analyzed in order to improve the adhesion force of the coating.During the low-pressure casting process

because of its unreasonable composition and single structure

the existing die heat insulating coating is easily dropped off block or being scoured and worn thin

and even it takes metal die be exposed to the air and aluminum liquid.Improvement methods for the existing insulating die coating was presenetd on the basis of comprehensive analysis of its composition.By means of improving the composition and introducing potassium titanate whisker and combining suitable spray ways

casting production efficiency was promoted effectively

and yield product rate was improved and production cost was reduced.
