New Kimura Foundry Adopts SinterCast for CGI

Indiana start-up operation will offer compacted graphite iron prototyping and low-volume production capability

Kimura Foundry America Inc., the greenfield ferrous foundry that started up recently in Shelbyville, IN, initiated a technology supply agreement with the Swedish process control specialist SinterCast AB for compacted graphite iron (CGI) product development, prototyping, and niche volume production. SinterCast will install a Mini-System 3000 at the Indiana plant and provide technical support for launching CGI production there.

The installation will be complete during Q2 2019, according to the supplier.

Compacted graphite iron (CGI) is a lightweight material that offers greater tensile strength, stiffness, and fatigue strength than gray iron or aluminum. It is mainly used by diesel and gas engine manufacturers seeking to reduce weight, noise, and emissions for their designs.

SinterCast’s CGI process control system centers on a metal sampling and testing technology that has been licensed by numerous foundries and research centers worldwide. The Mini-System 3000 is a mobile unit for CGI sampling and testing, and will make it possible for Kimura Foundry America to produce compacted graphite iron parts.

Kimura Group previously adopted a Mini-System 3000 for CGI production in Japan.

“Further to the installation of the SinterCast technology at our Japanese foundry, Kimura Foundry America is excited to install CGI capabilities at our new foundry in the United States,” stated Dr. Yoya Fukuda, president of Kimura Foundry America Inc.

He continued: “With the addition of the SinterCast process control technology, Kimura Foundry America can now offer short lead-time CGI components to regional OEMs and to our high-volume foundry partners. Together with our planned investment for increased cast iron melting capacity, Kimura will be able to meet the increasing market demand for the rapid development of new CGI engine programs for passenger vehicle, commercial vehicle and industrial power applications.”

The Kimura Group operates three foundries in Japan, producing iron castings for dies for stamping and diecasting, machine tool beds and frame structures, automotive engine parts, pumps, compressors and energy industry components. It also operates three pattern shops and three specialty-machining operations.

The Indiana plant is a start-up operation that relies entirely on 3D-printed sand patterns and molds to produce rapid prototypes and small-lot castings, for automakers and their suppliers; manufacturers of engines, industrial pumps, and machine tools; suppliers of agricultural, mining, and off-road equipment; and oil-and-gas and renewable energy projects.

“Kimura’s commitment to CGI product development capability in Japan and North America is a clear indication of the growing global demand for CGI product development. We are pleased that Kimura has benefitted from last year’s installation in Japan and we look forward to supporting their new facility in the U.S.,” said Dr. Steve Dawson, SinterCast president and CEO. “With the Shelbyville installation, Kimura becomes our eighth customer to have committed to multiple SinterCast installations.”
