We offer you OEM service for casting parts , especially in sand casting.

Sand casting,also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting  process.Sand casting is relatively cheap and sufficiently refractory even for steel foundry use. In addition to the sand,a suitable bonding agent is mixed or occurs with the sand. The mixture is moistened with water to develop strength and plasticity of the clay and to make the aggregate suitable for molding.The sand is typically contained in a system of frames or mold boxes known a flask. The mold cavities and gate system are created by compacting the sand around models, or patterns, and or carved directly into the sand. Can maintains typical tolerance accuracy within CT12-CT14 standard, with a surface finish of Ra50-100.


Yes,  We offer CNC service to make the surface of casting parts as polished & precise as you request.
