Description

Baoding Guokun Machinery Co., Ltd and Baoding Guokun Export and Import Trading Co., Ltd are located in Baoding city, Hebei province, China. 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.

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

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.

Ductile iron or nocular cast iron or spheroidal graphite iron is a type of cast iron with added magnesium or cerium, which gives it enhanced ductility and toughness compared to traditional gray cast iron. Its key propeties include: high tensile strength, good impact resistance, excellent corrosion resistance, machinability and wear resistance. A flange is a protruding rim used to connect pipes, valves, pumps, and other equipment in piping systems. Ductile iron flanges are commongly used in water and wastewater systems, oil and gas pipelines, fire protection systems, industrial and municipal applications. The cast ductile iron sand casting flange produced by Baoding Guokun is an excellent choice for water, sewage, and moderate-pressure industrial applications due to their strength, durailities, and cost benefits. However, for extremely high-pressure or corrosive environments, stainless steel flange or speicialized alloys pipe flange may be preferred. Ductile iron flanges are manufactured under various standards, including: AWWA C110/A21.10 ( Waterworks flange), AWWA C115/A21.15 Flange ductile iron pipe, ANSI/ASME B16.1 Class 125 & 250 flanges, EN 1092-2 European standard and ISO 7005 international standard.
