The advantage and disadvantage for smelt mold casting technique

Professional liebherr excavator lock pins production supplier said the advantage of smelt mold casting technique is never worry about the carbon flaws problem, due to the pouring process is finished in the empty cavity state, but professional liebherr excavator lock pins production supplier said the disadvantage of smelt mold casting technique is its common smelt mold casting needs been produced with seven to eight layer covers, which also needs continue baking with the high temperature( range from eight to nine hundred high temperature), so the surface coating layer on liebherr excavator lock pins cover would produce reaction changes, but increase the strength for cover part.

Professional liebherr excavator lock pins production supplier said the entirety smelt mold casting technique process must be finished with several complex procedures and long time, especially of the high temperature baking process, which would consume more electric energy.

But since recent years, more and more professional liebherr excavator lock pins production supplier start to adopts the vacuum pouring technique to instead of smelt mold casting technique, which would shorten the total cover manufacturing later to only three to four layers, but also never adopts the high temperature baking process anymore.
