Aluminum Sand casting is traditional casting process in China, it is
major inventions of ancient China, it is important as China's four
great inventions. The sand cast process originated in the Southern and
Northern Dynasties, about 1600 years ago.
Our aluminum foundry is set up in 1995 year. First, we only have green
sand casting process, then We built resin sand casting line in 2000
year. Now we have five production lines for large aluminum green sand
casting jobs up to 500kg/piece and 30 platforms for smaller aluminum
alloy castings. Meanwhile, we have one production line for resin sand
casting . We are leading in China foundries in Zhejiang province.
There is green sand casting process for sand casting manufacturer, but
we have two process.
We make molds in our foundry and we have a good ability in sand
casting mold design, It is difficult for many China sand casting
factories. So if you have decision to cooperate with us, we must be a
good sand casting supplier for you and your company.
Our cast aluminum products are exported America, Europe and Asia
market, including auto components, furniture components, lighting
components, pump valve components, architectural components and so on.
The Introduction : Sand Castings
Sand casting is used to make large parts, suitable for Aluminum alloy,
Iron, Steel and Brass metal. There are two techniques: green sand
casting and resin sand casting. The sand cast molds are same for the
two ways, their difference is only sand. Green sand is for green sand
casting process, which is the most common used by foundries; resin
sand is for resin sand casting process or making cores.
·The "green sand" consists of mixtures of sand, clay and moisture.
·The "resin sand" consists of sand and synthetic binders cured
thermally or chemically
·The cores used for forming the inside shape of hollow parts of the
casting are
As usually, the material of sand casting moulds is wood, silica or
aluminum alloy. If the aluminum part is small, the quantity is less
and the structure of castings is easy, we make the casting parts by
wood mold or silica mold, such as furniture components, architectural
components; If the structure is complex, the aluminum product is very
big, or the order will be continued several, we suggest to make the
sand casting parts by aluminum alloy mold, such as engine blocks,
cylinder heads, housing.
The sand mould is re-usable and permanent patterns, there are some
pouring cups and risers on the moulds. How to set up the pouring cup
and riser is the key in moulds design
