Successful die casting or sand casting process adds value to your business and gives you a head start on the competition.  You can stand out with high product quality, great service, low prices. 

But it's important to choose suitable process to your product, as they eventually decide how to win in the market. 

In this post, I'll help you learn the processs of die casting and sand casting .

What is difference between Sand casting and Die casting?

1. 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 parts.

but the die casting part has less gas porosity and much good surface appearance. you can choose surface finish like: plating, sand blasting, passivation.

3. The thickness of sand castings need to be larger than 3mm, and need to be machined by CNC much more locations. so the product cost is very high.

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

4. Sand casting mould is very easy to be modified. we can make it by wooden and aluminium. so if you have larger change on the design. the cost also very cheapest.

Instead, the material of die casting mould is iron (H13 or 8407 or 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 first.

5.  Sand casting is the use of clay bonded sand molding materials for the production of castings, is a long history of the process, is also the most widely used process methods. Speaking of a long history can be traced back thousands of years ago;

A metal casting process characterized by applying a high pressure to the molten metal using a mold cavity. Molds are usually made of alloys with higher strength, and this process is somewhat similar to injection molding.

Sand casting and die casting each have advantages and disadvantages.
