Casts produced with this method have smooth surfaces, accurate dimensions and high geometrical precision. This method is suitable for shaping complicated thin-wall parts, instrumental to improving product performance, reducing structural weight and manufacturing cost, so it’s applied more and more widely in industrial production.
