**Water Pipe Fittings**: The company offers a range of products including YD-coupling, Union (Black/White, 15-80A, FCMB270 material, working pressure below 10kg/㎠, anti-rust or hot-dip galvanized surface treatment), PM Joint, HP Joint, and steel pipe connectors. In 2002, it developed and commercialized the SF Joint, a fitting for PE multi-wall sewage pipes. Newer proprietary products for HI-VP pipes include the Wrap Joint (16A~200A, with improved watertightness and high-pressure anti-detachment capabilities) and the HM Joint (16A~300A, a mechanical joint with integrated watertight packing and a precision-machined aluminum stopper for anti-detachment), along with the HP Joint (125A~400A, a split flange type).**WaterPipeFittings**:ThecompanyoffersarangeofproductsincludingYD-coupling,Union(Black/White,15-80A,FCMB270material,workingpressurebelow10kg/㎠,anti-rustorhot-dipgalvanizedsurfacetreatment),PMJoint,HPJoint,andsteelpipeconnectors.In2002,itdevelopedandcommercializedtheSFJoint,afittingforPEmulti-wallsewagepipes.NewerproprietaryproductsforHI-VPpipesincludetheWrapJoint(16A~200A,withimprovedwatertightnessandhigh-pressureanti-detachmentcapabilities)andtheHMJoint(16A~300A,amechanicaljointwithintegratedwatertightpackingandaprecision-machinedaluminumstopperforanti-detachment),alongwiththeHPJoint(125A~400A,asplitflangetype).
**Automotive Parts**: YDI produces various components for automobiles and heavy equipment, such as engine, manual transmission, propeller shaft, power steering pump, and hydraulic valve parts. The company concentrates on developing new materials essential for automotive lightweighting and fuel-cell vehicle development, including projects for Hollow type cam shafts and Thin stainless steel exhaust manifolds. Production methods involve Green sand, Shell mold processes, and Aluminum gravity casting for cast iron and aluminum materials and their processed products. YDI is recognized for achieving quality stabilization of Pearlitic Malleable Iron and for exclusively supplying Fork Shift and Engaging Piece components for transmissions to Korean automobile manufacturers.**AutomotiveParts**:YDIproducesvariouscomponentsforautomobilesandheavyequipment,suchasengine,manualtransmission,propellershaft,powersteeringpump,andhydraulicvalveparts.Thecompanyconcentratesondevelopingnewmaterialsessentialforautomotivelightweightingandfuel-cellvehicledevelopment,includingprojectsforHollowtypecamshaftsandThinstainlesssteelexhaustmanifolds.ProductionmethodsinvolveGreensand,Shellmoldprocesses,andAluminumgravitycastingforcastironandaluminummaterialsandtheirprocessedproducts.YDIisrecognizedforachievingqualitystabilizationofPearliticMalleableIronandforexclusivelysupplyingForkShiftandEngagingPiececomponentsfortransmissionstoKoreanautomobilemanufacturers.
