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. Baoding Guokun can produce and export various agricultural casting components for agricultural machinery, combine harvester, farm implements, tractors, plows, harrows, seeders, fertilizer spreaders, balers, wagons or trailers, cultivators. The investment casting and sand casting process are usually the most cost-effective casting techniques to produce complex or simple agricultural casting replacement components in low, medium and high-volume quantities.

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:

Cast iron railway axle box body

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.

The railway wagon axle box is a critical railway component, applied on railway vehicle bogies. The axle box is mounted on axle journal to connect wheelset and bogie frame. The cast iron axle box produced by Baoding Guokun is to transfer the weight of railway vehicle body and the load to wheel and axle, to lubricate the axle journal, to reduce the friction, and to reduce the train running resistance. The customized axle box is typically made of cast iron or cast steel.
