What is difference between die casting and sand casting





Sand casting —the cost of mould is lowest ,and the production time is short. you can  quick occupy the market with low risk of project input.

but die casting need more time for making the mould .and the cost of mold  is so expensive .

2. There are more sand holes in the sand casting part ,and the surface apperance is bad.we only suggest choosing powder coating for sand casting part .

but the die casting part has little Gas porosity and good surface appearance . you can choose   Surface Finish like :plating ,sand blasting ,anodizing .

3.sand casting thickness need large than 3mm, and need machine more by  cnc the product cost is very highest

but the thickness of die casting part can be min 1.5mm

4.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.
