Inner Diameter Thickening Processin

  • Sprocket for Oil pumps

    Usage：Oil pumps for transmisison

    Pressing spline shapes for O.D. gears and I.D. gear.

  • Gear Sun

    Usage：Electric actuators

    Using a transfer press, we machine a tooth profile with a shear face of 70%, a protruding profile at 9 locations, and a protruding profile on both sides of the inner diameter.

Precision Shearing

  • Sprocket for Oil pumps

    Usage：Oil pumps for transmisison

    Pressing spline shapes for O.D. gears and I.D. gear.

  • Sprocket Drive

    Usage：Electric bicycles drive parts

    Using only pressing, the center 8 mm is raised, machined into a spline shape on its inner diameter, and its dimension is secured, from a plate thickness of 2.9 mm.

  • Sprocket

    Usage：Oil pumps for transmissions

    Precision press enabled us to change from the conventional sintering method to press-worked inner diameter splines.

  • Gear Ring

    Usage：Electric actuators

    The transfer press is used to form the tooth shape of the inside diameter and the outer circumference.

  • Gear Sun

    Usage：Electric actuators

    Using a transfer press, we machine a tooth profile with a shear face of 70%, a protruding profile at 9 locations, and a protruding profile on both sides of the inner diameter.

  • Sprocket

    Usage：Engine camshafts

    We have succeeded in reducing costs and weight by proposing "press + carbonitriding" instead of the conventional "sintered + induction hardened products." We work on sprockets of various shapes.

  • Crank Angle Sensor

    Usage：Engine crankshafts

    High-precision machining of outer sensing area.

  • Gear Sprocket

    Usage：Electric variable valve timing system

    Sintered products are processed by all-press. Gears in the inner diameter section are shaved to ensure 80% shear surface.

Precision Plate Forging

  • Cam Pilot

    Usage：4WD units

    The conventional sintering method has been changed to pressing. Furthermore, carburizing and nitriding achieved cost reduction and increased strength.

Extrusion Processing

  • Forged Gear (Extrusion method)

    Usage：Reduction unit gears

    Pressing is used to form the outer tooth tips by applying pressure from above and below.

Precision Molding Processing

  • Motor Rotor Magnet End Plate

    Usage：Hybrid motors

    High-precision forming of SUS material with rolling anisotropy is realized.In particular, the stepped forming of the oil channel portion for motor oil cooling reduces warping distortion.

  • Adapter

    Usage：Air conditioning units

    Aluminum material is formed into complex shapes. In addition, processing with minimal burr.

Insert Molding

  • Gear Pulsar

    Usage：Engine camshafts

    While maintaining the features of products conventionally formed by the sintering process, the combination of steel and resin not only reduces weight, but also ensures strength.

  • Insert Gear

    Usage：Actuators

    The outer gears, which require strength, are pressed from steel to ensure accuracy.We proposed resin insert molding for the areas where strength is not required to make them light.

  • Gear

    Usage：Water pumps

    Forging + tooth cutting method" was changed to steel press for fastening part and tooth part was changed to insert molding product. Multi-materialization has made this product stronger and lighter.
