Challenging high quality at a low cost, starting in 1972.
Equipped with cold forging presses with a capacity of 220 to 630 tons, we have expanded the range of our forging processes from the conventional carbon steel and alloy steel to the nonferrous field, including copper and stainless steel. To realize integrated production, we employ various types of ancillary equipment such as cutting machines, non-oxidizing annealing furnaces, zinc phosphate coating devices, and barrel grinders. We have earned customer satisfaction by establishing a comprehensive system to carry out all the tasks in-house: from process design, simulation, die design/manufacture, to product inspection. |
