Sand casting and Die casting

Sand Casting Vs Die Casting

1 Moldeo en arena —Pequeño costo de molde, corte rápido en el mercado, bajo riesgo de entrada de proyecto. pero a presión fundición necesidad de más tiempo para hacer el molde .and el costo es tan caro .

2. There are more sand holes in the sand casting ,and the surface apperance is bad .and die casting part has good surface appearance . only a little sand hole .so we need fix the problem by hand .for example ,putty or welding the surface,polish the rough surface .

3.sand casting thinkness need large than 3mm, and need machine more by cnc machining .so the product cost is very highest than die casting part .

4. Surface finishedwe only suggest choosing powder coating for sand casting part . and for die casting ,you can use Surface Finish Metal Parts

5.sand casting mould is very easy to modify . we can make it by wooden and aluminium . so if you have large change on the design . the cost also very cheapest . instead ,hard and more cost for modifing the die casting tooling .the die casting mould material is iron (h13,8407,skd61),the hardness is about HRC 46° -48° . so if you choose die casting ,we suggest to make rapid prototype first to check the design.
