Shell Molding & Sand Castings Foundry | Heat, Wear, Abrasion, and Corrosion Resistant Steels

 

Steel Castings for Mining, Rail, Municipal, Power Generation, Machinery, Industrial Plants, and Steel Mills

 

 

Founded in 1989, our shell molding and sand castings foundry based in Cheonan, Korea is a TUV ISO 9001:2008 certified facility for castings of carbon steels and stainless steels and is also Lloyd’s and DNV marine classification certified. Through our diverse experience with various industries, we are able to meet a wide range of casting requirements for the mining, locomotive, power generation, and petrochemical industry. We have a production capacity of 300 tons and the capability of producing green sand castings up to 2,500 kg.

 

Some of our exemplary clients include companies such as Doosan Heavy Industries, Hyundai Steel, POSCO, Dongwoo Finechem, Advance Valve Solutions, Metso, WEIR, and Kurimoto.

Industrial Castings | Carbon Steel, Stainless Steel, Alloy Steel

Our foundry in South Korea was founded in 1989, specializing in producing various wear-, heat-, corrosion-, and abrasion-resistant castings. Typical castings include a range of carbon and carbon-manganese steels (SCHP2, WCB), austentic stainless steels (SCS14A, CF8M), and various alloy steels (SCHP32/CF, WC9).

 

Our refining and alloying practice includes Carbon, Metal Nickel, Ferro Chrome, Ferro Molybdenum, Ferro Silicon, Ferro Manganese, Copper, Nitrogen-Chrome, Columbium, Titanium, Tungsten, Aluminum, Vanadium, and Calcium-Silicon. We may also be able to accommodate special requests for other materials.

 

We utilize high speed induction furnaces and have 3 ton ladles to producing steel casting weights ranging from 1 kg to 2,500 kg. The majority of our processes are conducted in-house including nondestructive x-ray and gamma-ray (Co-60 & Ir-192) radiography testing.

Power Generation & Industrial Plant Steel Castings

We have over 25 years of experience casting carbon steel and stainless steel valves and valve components for the power generation and industrial plants include globe valves, check valves, ball valves, butterfly valves (BFV), plug, rotary, safety, strainer, and gate valves. We are also able to produce complex shaped steel castings for volute covers, pump casings, and impellers.

 

Our expertise in shell mold casting of various heat resistant and wear resistant steels allows us to maintain tight casting tolerances. Due to the ability to maintain close tolerances for products such as biomass incinerator grate bars, many of our clients have often found that minimal or no further post-casting machining process is required thus resulting in time and cost savings.

Manufacturing & Casting Process

Our foundry utilizes CO2, Sand Casting, and Shell Mold Casting processes. Depending on the size and shape of the casting, we are capable of producing sand castings up to 2,500 kg and shell mold castings up to 50 kg. Typical castings that we produce include components for valves, pumps, machinery, mining, train, and refuse biomass incinerator components.

 

Nondestructive testing (RT, UT, MT, PT) is performed in-house and with third-party NDT inspection companies with DNV-certified inspectors. Our in-house radiographic testing (RT) equipment includes x-ray, iridium (Ir-192), and cobalt (Co-60) gamma ray testing.
