The strength of the DCFSegment & Sprocket SEGMENTOur segments combine strength and excellent wear with produc-tion efficiencies that result in a high level of customer satisfaction.

SPROCkETDCF Sprockets are able to supply safe, reliable drive systems,soundly based on the hallmark characteristics of the DCF brand:extensive know-how, flexible design responding rapidly and effec-tively to customers' needs.

According to common experience, 50% or more of the maintenance costs during the life of a crawlertractor(dozer) or crawler loader belongs to undercarriage maintenance and repairs. Increasing the lifeof undercarriage components is the winning strategy to reduce ownership and operating costs.

Due to the robustness and economy, DCF’s sprockets and segments have been applied to variousmodels.

Forging

ART PRODUCTION

Daechang Forging(DCF), Since its founding, inthe field of forging industry has been lead-

ing the production of UndercarriageParts for Heavy Equipment(Excavator,Bulldozer), Crankshaft for Automo-bile & Marine Engines and many other

Industrial fields.

DCF is globalized, and famous forworldwide distribution of GenuineParts and Repair Parts for thoseUndercarriages, Crank shafts andother industrial parts.

One of DCF’s strongest points isits knowledge of hot forging tech-

nology, developed through years ofhistory and experience. DCF investedconsiderable resources in the biggest

hot forging line, whosemain component is a6,300 Ton ForgingPress. In addition,we robotized linesfor productivity im-provements, costreductions andsafety of theForging Process.

Artificial intelligence and vision techniques have beendeveloped for the automatic inspection of each single

component, thus reducing productiondefects (such as those occurring

after hot forging or heat treat-ment) practically to zero.

Great efforts have beendedicated to develop-ing new materials andrefining heat treatment

processes, in orderto guarantee bet-ter, longer lastingproducts.
