Our sand-casting factory occupies a total area of 30,000 square meters, which have casting foundry workshop, grinding, sandblasting and precision machining shop, laboratory and warehouse. Baoding Guokun has equipped with 4 sets medium-frequency electric furnaces, 15 sets automatic shell core machinery, automatic sand-casting molding line, 7 sets CNC machinery, 20 sets CNC Lathe, and the complete quality inspection devices for mechanical testing and chemical analysis, including tensile strength, hardness tester, metallographic inspection, spectrometer, ultrasonic testing and special testing devices. Before shipping, the quality reports for all inspection will be issued and mailed to our customers. We can offer green sand casting, resin sand casting, precoated sand casting, shell mold casting process for your OEM casting parts. The investment casting and sand casting process are usually the most cost-effective casting techniques to produce complex or simple gearbox casting replacement components in low, medium and high-volume quantities. The types of gearbox reduced housing, helicopter transmission components, gearbox components, main rotor gearbox housing, tail rotor gearbox housing, gearbox casing, transmission housing, bearing housing, we can produced and exported are as follows:

Cast Iron Gearbox Reducer Housing: Durable and commonly used for heavy-duty applications. Mainly produced by sand casting process and lost foam casting process.

Aluminum gearbox reducer Housing: Lightweight and corrosion-resistant, often used in applications where weight is a concern. Mainly produced by gravity casting, sand casting and die casting process.

Stainless Steel helical bevel gearbox Reducedr Housing: Used in corrosive environments or industries like food processing or pharmaceuticals. Mainly produced by investment casting or lost wax casting process.

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, gearbox components, 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

What is lost foam casting process?

Lost-foam casting is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. The lost foam casting techniques take advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need of melt the wax out of the mold. Compared with investment casting method and sand casting techniques, lost foam casting is one of the most cost-effective and environmentally friendly metal casting process for creating complex and intricate metal parts by using a foam pattern that evaporates when molten metal is poured into it:

Lost foam casting process
Create the foam pattern	Create the foam pattern: The pattern is made from pre-expanded polystyrene (EPS) that is heated in an aluminum die to expand and fuse the beads. The pattern can be carved, machined, or created using injection molding.
Coat the foam	A ceramic refractory coating is applied to the foam to protect it from the sand and create a barrier
Compact the sand	The foam pattern is placed in a flask and surrounded by unbonded sand, which is compacted using a vibration table.
Pour the metal	Pour the metal: Molten metal is poured into the flask, causing the foam to evaporate and leaving behind the metal
Remove the coating	Remove the coating: The refractory coating is removed to expose the metal part.
Surface treatment	Sandblasting and machine process.

A cast iron castings is typically made from gray iron as it is the most common cast iron due to its good castability, machinability, and vibration damping properties, although in situations requiring higher strength and impact resistance, ductile iron might be used instead.

Gray cast iron	ASTM A48 Standard Specification for Gray Iron Castings, for example, ASTM A48 Class 30, ASTM A48M class 35, ASTM A48 class 40, etc.	More brittle but has better vibration damping and is generally cheaper than ductile iron.
Ductile cast iron	ASTM A536 Standard Specification for Ductile Iron Castings. ASTM A536 grade 65-45-12, ASTM A536 Grade 80-55-06, ASTM Gade 60-40-18, etc	Offers greater strength and ductility, making it suitable for applications with higher impact loads.

Gray cast iron is the most common cast iron for helical bevel gearbox housing, helical-bevel gearmotor housing, reducer housing, bevel helical gearbox housing, pump housing, motor housing, gearbox housing, bevel gearbox gray iron housing, etc. Baoding Guokun can offer you the machining process for your customized gearbox housing as per your drawings or design.
