Doosan Infracore,
Korea’s largest manufacturer of construction equipment and diesel engines, looks
set to embark on equipping some of its diesel engines with compacted graphite iron
(CGI) cylinder blocks.
The company has ordered a second process
control system from the Swedish CGI process control specialist SinterCast.
Following the first SinterCast installation
in 2006, and successful materials research and product development within
Doosan Infracore, the new MiniSystem 3000 will be used for the production of
the CGI cylinder block of a new diesel engine developed for demanding off-road
applications.
Doosan Infracore needs the additional system for two reasons: it wants to allocate one system for product development and the other for production. It is common for foundries to have an 'off line' area for material and product development. With the latest system Doosan engineers can focus on production at the same time as development, hence speeding upboth processes.

Initially at
least the CGI cylinder blocks will feature in a new, bespoke high-displacement
off-highway engine destined for demanding applications. But other
applications could follow as the company gathers experience with this important
automotive engineering material.
Doosan
manufactures a wide range of high quality diesel engines for industrial, construction,
power generation, commercial vehicle and marine applications.
In the
off-highway sector, Doosan’s engines range from a 5.8-litre unit giving 116bhp
and 353Nm torque, through 8.1-litre, 11.1-litre, 14.6-litre and 18.3-litre to
the largest at 21.9-litre. The 21.9-litre unit can deliver 800bhp and 3,205Nm
torque.
In on-highway
applications, Doosan engine sizes range from 5.9-litre, 7.6-litre, 8.1-litre, 11-litre
and 11.1-litre to the largest at 14.6-litre. In this duty, the 5.9-litre
delivers 240bhp and 804Nm torque whereas the largest 14.6-litre unit gives
420bhp and 1,666Nm torque.
Together, the two SinterCast installations
will be used to enable independent and formidable CGI product development and
series production within Doosan Infracore.
The Mini-System 3000 is expected to be
installed during the second quarter of 2015, with the initial CGI production
beginning upon commissioning of the system. The installation of the second
system will mark an important milestone for SinterCast which has been making
steady progress with equipment installation in Asia.
“We are pleased that Doosan Infracore’s
successful CGI product development, together with SinterCast’s commitment to
the important Korean market, has led to this second installation. The launch of
a new engine, and Doosan Infracore’s investment in a second process control
system, reinforces the global trend toward CGI in the heavy-duty diesel sector
for both on-road and off-road applications” said Dr. Steve Dawson, president and
chief executive officer of Stockholm-based SinterCast.
“We are motivated by Doosan Infracore’s
confidence in our technology – repeat business is the strongest endorsement of
any technology, and one of our core objectives,” he concluded.
