Carbon Steel Construction Casting
Casting Alloy: 1025, 1035 1045 are the most common alloys we poured. This alloy grade is relatively soft among all carbon steel alloys. 4130 4140 4330 4340 are the most common alloys we poured. This alloy has high-level hardness and it is really hard to be bended.
Casting process: Carbon steel silica sol investment casting. Carbon steel sand casting is the most economical way to make the part. However, the surface roughness will not be that good. If you want relatively big part with OK surface finish, Water glass process is your best option. Besides, silica sol investment casting process will be your best choice if you want to get the good finish part. It all depends on your requirements and budget range.
Casting Tolerance: CT4-CT6
Machining Tolerance: IT4-IT12
Investment Casting Process
As we started as an investment casting foundry, we know details of this metal-forming technique. Investment casting is also known as lost wax casting. Basically, it refers to make a wax pattern formed with a ceramic. Then, melting the wax makes the ceramic empty. Eventually we get the casting after pouring the metal into the ceramic. OTTOMMO Casting continues to improving our process and utilizing the newest technology available in our industry.
Die Casting Process
Die casting refers to force the molten metal under high pressure into reusable metal dies. Then, we get the raw casting after metal solidifies rapidly. This process is a quick and cost-effective method for high volume geometrically complex parts. In 2010, OTTOMMO Casting established the die casting plant as our joint venture. We aim to provide you high-quality non-ferrous casting parts. Besides, we are capable of full in-house CNC machine, surface treatment and assembly.
Sand Casting Process
As a cost-efficient casting method, sand casting is still popular in China. Basically, it refers to make a sand mold with cavity of casting shape inside. Then, we get the casing after pouring metal into the cavity and metal solidifies. In OTTOMMO sand casting plant, we have both manual and semi-automatic sand casting production lines for castings with various size, weight and geometries. Besides, our sand casting capacity ranges from 3 lbs. to 2500 lbs.
