▶ Product name : Transmission gear used for large trucks or buses
▶ Production equipment : Produced using large scale press (3,500 tons and 4,500 tons) equipment
▶ Work scope : Workable up to ø320 mm in external diameter of flange. Regarding the product appearance, the Rib part is thin and wide, therefore, overload can be caused to the machine, and thus design has been made in consideration of safety rate.
▶ Technology features : Because many quality problems occur at the Rib joint part, caution is required in designing. To reduce weight and standard operation time, this product is produced by inserting a hole in the Rib part.
▶ Product name : Drive pinion used for joint part with axle, when driving power is delivered from transmission to axle of a car.
▶ Production equipment : Tooth form's transformation extent has been improved in carburizing through collection rate increase and grain flow line improvement using a vertical forging method in the rough shaping.
▶ Product name : Ring gear used for a device changing the rotation direction of rotating force delivered from car's transmission and driving to both wheels (This is the rotating part interlocking with drive pinion).
▶ Production equipment : When grain flow line is formed vertically against the tooth surface, minimum tooth form transformation is caused in the case of carburizing after processing. Therefore, the grain flow line has been improved by setting the standards of original material dimensions and carbon steel dimensions.
▶ Product name : Rear axle shaft for cars
▶ Production equipment : Produced by UPSETTER, a forging device for car axle shaft, and there are 5'' UPSETTER and 7.5" UPSETTER.
▶ Work scope : Currently producing FLANGE with ø210 mm in external diameter, SHAFT with ø70 mm in external diameter and forged products with max. 40kg in weight
▶ Technology features : The product, manufactured by welding a shaft and a flange in the past, is forged and completed as all-inone type using the UPSETTER equipment. Therefore, there are such effects as welding cost savings and strength improvement.
▶ Product name : Yoke, which is a propeller shaft part delivering transmission's rotating force to an axle
▶ Production equipment : Forming of the product shape is difficult, and thus complex flash shape is shown.
▶ Work scope : Production facility is decided, according to product size, and the above product is produced using a 2,500 ton PRESS.
▶ Technology features : Quality problems like underfill or overlapping can be easily caused; therefore, blocker mold design is important, and the material needs to be accurately placed on both horn parts in forging.
▶ Product name : C/V joint, C/G joint assembled in the driving axle connecting transmission and a wheel.
▶ Production equipment : A product with a cup shape connected with a long axle. This product can be an auxiliary part.
▶ Work scope : Mainly produced using a small scale press, and the product with max. 180mm in length is produced.
▶ Technology features : Because, this product has long axle, an extruding forging method and bound forging method should be simultaneously used to ensure good quality at the end of the axle.
