The main product lines consist of chain guide bars, spring housings for large engines, and key cylinder head components for medium-sized engines. The company produces various precision parts such as valve rotators, valve guides, bushes for cylinder heads, valve seat rings, studs for fuel valves, and thrust shafts for idle gears & camshafts.Themainproductlinesconsistofchainguidebars,springhousingsforlargeengines,andkeycylinderheadcomponentsformedium-sizedengines.Thecompanyproducesvariousprecisionpartssuchasvalverotators,valveguides,bushesforcylinderheads,valveseatrings,studsforfuelvalves,andthrustshaftsforidlegears&camshafts.
The chain guide bar acts as a cushioning and protective device, preventing collision damage between the chain and engine frame during engine operation and ship inclination. This product is an exclusively produced item, developed through patented technology for specific adhesion between rubber and steel, and continuous research for enhanced durability.Thechainguidebaractsasacushioningandprotectivedevice,preventingcollisiondamagebetweenthechainandengineframeduringengineoperationandshipinclination.Thisproductisanexclusivelyproduceditem,developedthroughpatentedtechnologyforspecificadhesionbetweenrubberandsteel,andcontinuousresearchforenhanceddurability.
The spring housing absorbs the reaction force of the fuel injection valve during oil spraying, reducing impact and extending the valve's lifespan. It is applicable to all types of MAN B&W engines, with a quality assurance system involving dedicated pressure tests for all products.Thespringhousingabsorbsthereactionforceofthefuelinjectionvalveduringoilspraying,reducingimpactandextendingthevalve'slifespan.ItisapplicabletoalltypesofMANB&Wengines,withaqualityassurancesysteminvolvingdedicatedpressuretestsforallproducts.
The valve rotator enhances the durability of the valve spindle and valve seat by rotating the valve spindle. This rotation prevents carbon deposition and one-sided wear, and effectively distributes temperature across the valve spindle and valve seat.Thevalverotatorenhancesthedurabilityofthevalvespindleandvalveseatbyrotatingthevalvespindle.Thisrotationpreventscarbondepositionandone-sidedwear,andeffectivelydistributestemperatureacrossthevalvespindleandvalveseat.
As a pioneer in the development and completion of valve rotators in Korea, the company's proprietary technology allows application to all 4-stroke diesel engines and custom manufacturing to meet customer requirements. It holds a patent for a valve rotator with 11 oil holes.AsapioneerinthedevelopmentandcompletionofvalverotatorsinKorea,thecompany'sproprietarytechnologyallowsapplicationtoall4-strokedieselenginesandcustommanufacturingtomeetcustomerrequirements.Itholdsapatentforavalverotatorwith11oilholes.
