Doosan Infracore Engine
Doosan Infracore has manufacturing plants building engines and metal castings
Engine manufacturing plants cover 38,300m2 and a casting manufacturing plant covers 20,000 m2.
Doosan builds 55,000 tons of castings a year.
All Doosan Infracore engines have its own built cylinder blocks and cylinder heads.
In 1975, Korea’s first casting manufacturing plant was established to build Doosan’s own
cylinder blocks and cylinder heads.
A cylinder block and a cylinder head are 5C parts of engines which are the most important parts
of an engine.
Let’s look into how a cylinder block and a head are built.
First, main material, metal should be melted.
Melted metal is poured into a mold to harden into shape.
We called this “Liquid Metal“ and pour them into a mold which is made from sands.
In order to produce a block and a head which have complicated internal and external surface,
“Core” procedure is necessary.
A core is a replica, of the internal features of the part to be cast which mold internal of parts.
Over 1,500 degrees Celsius of liquid metal is pored into a mold and wait for a while to cool down
Then next, inside and outside of parts are cleaned.
Now parts are ready to be painted.
Final process is inspection. After going through thorough test, then it’s good to be delivered to customers.
Doosan Infracore has 18 models of cylinder blocks and 10 models of cylinder heads
Does Doosan Infracore only build its own parts?
Of course not. We also develop new products.
Here is a customer who needs a new hydraulic pump and other parts.
New equipment require newly designed parts.
Doosan Infracore develops new parts with a customer.
Long and rich experiences in development of various products and mass production are enable
to meet diverse demands of customers.
Doosan Infracore always tries to meet the needs of customers.
