Baoding Guokun sand casting pouring process

Ductile iron is a type of cast iron with a unique microstructure that gives it high strength, flexibility, and durability. It is also known as sepherodial graphite iron, nodular cast iron or SG iron. Baoding Guokun can produce various gearbox components, such as gearbox housing, gears, drive shafts, mounting bracket, gearbox components, gearbox parts, reduction gearbox housing, reducer gearbox housing, gear housing, gear box cases, die casting aluminum gearbox, ductile iron gearbox housing, gearbox casting, gearbox casing, etc.

Ductile cast iron grades

Ductile cast iron: ASTM A536 refer to the standard specification for ductile iron castings. Baoding Guokun, a China sand casting factory, can manufacture various pumps, valves, agriculture parts, motor castings, railway castings, marine castings and other engineering casting components in several grades of ductile iron, including:

ASTM A536 Grade 60-40-18 is a nodular iron with a mostly ferritic microstructure and mechanical properties comparable to low alloy steels.

ASTM A536 Grade 65-45-12 is a nodular iron with a ferritic and pearlitic microstructure and mechanical properties comparable to low alloy steels.

ASTM A536 Grade 80-55-06, relating standards SAE J434C D5506 or ISO 1083 500-7, is a nodular iron with mostly pearlitic and smaller amount of ferrite microstructure.

ASTM A536 Grade 100-70-03, named pearlitic ductile iron, includes graphite spheroids in a matrix of pearlite. The pearlite matrix is comparatively hard and has high strength, combined with good wear resistance. This is combined with average ductility and impact resistance.

ASTM A536 Grade 120-90-02, named Martensitic ductile iron, has low to zero pearlite formation due to specific alloy additions, and can be quite hard and brittle in its untampered form.

Sand Casting process, resin sand casting, green sand casting, precoated sand casting, shell mold casting process

Sand casting process is an industrial metal casting process that involves creating a mold from sand and pouring molten metal into it, generally used to cast the shaped parts of nearly any design, including large parts and those with internal passages. Baoding Guokun can produce various sand cast parts in cast iron, ductile iron, gray iron, low-carbon steel, mild steel, alloy steel for pump, valve, agriculture, railway, road, forklift, tillage, mining, automotive, medical, food, and aircraft, etc.

The process of Baoding Guokun sand casting involves several steps after producing a professional tool or mold, including:

No.	Steps	Details
1	Pattern Creation	A two-piece metal pattern is created in the shape of the desired part, typically from iron, aluminum or wooden material.For a single casting or small batches of castings, we prefer to produce to use the wooden material to manufacture the mold to save money for customers.For other sand casting parts in large quantity, we prefer to use aluminum or iron to improve the mold’s service life.
2	Mold creation	The two shell halves are joined together and securely clamped to form the complete shell mold. If any cores are required, they are inserted prior to closing the mold. The shell mold is then placed into a flask and supported by a backing material.
3	Pouring	The mold is securely clamped together while the molten metal is poured from a ladle into the gating system and fills the mold cavity.
4	Cooling	After the mold has been filled, the molten metal is allowed to cool and solidify into the shape of the final castings.
5	Raw Castings	After the molten metal has cooled, the mold can be broken and the casting removed. Trimming and cleaning processes are required to remove any excess metal from the feed system and any sand from the mold
6	Machining	Machining as per drawings
