5000kN Ram Traveling Press

5000kNx2 Coupled Press Brakes

Triple Action Type Wheel Press

10000kN Ram Head Traveling Type Press

10000kN Hot Plate Press

35000kN Powder Forming Press

Hydro-Forming Press

Special Features

  • Feature on Die
    Only convex die is required. There is no need for hollow die. Convex die can be made of even plastic.
    Tapered and parabolic drawn parts are produced in one forming operation while the classical drawing method generally requires 5 to 6 press operations and 1 to 2 intermediate annealing operations.
  • Feature on Products
    Since the material thinning at the bottom radii is very small, thinner sheet metal can be formed.
    An outstanding surface finish can be obtained because the sheet metal is drawn over a hydraulic cushion and not over the edges of a drawing die.
    Excellent product shape can be obtained because pressure and speed can be set up according to forming condition.
    No deformation after forming will break out.
  • Feature in Operation
    This Hydroforming Press can be used as both of Double Action Deep Drawing Press and Single Action Deep Drawing Press (with Inner/Outer locked) when the Dome is put out of Press.

Hybrid System

Lead Press in Tandem Line used to necessarily be Double Action Press. In accordance with the progress in Die mechanism and Die Cushion Device Single Action is getting to cover most of Deep Drawing Operation. Eventually Double Action Press is not necessarily required recently as lead presses for the saving of Dies cost and Maintenance cost.
Notwithstanding this situation Double Action Press can not be eliminated, because of its use for the forming of Service Parts and Special Parts, and are operated in Single Action use by using only inner ability to make most use of facility.

KOJIMA developed KOJIMA HYBRID PRESS SYSTEM in collaboration with Hyundai Motor Company (Seoul, Korea) in which both usage as Single Action and Double Action can be obtained by putting additional hydraulic system to Double Action Press.

Special Features

  • Single Action mode will be available on Double Action Press by setting additional hydraulic device.

    1.Full power of Inner and Outer can be utilized.
    2.Maximum area of Slide can be utilized.
    3.SPM remains the same as original specification.

  • Double Action mode is also available.
  • SPM as a line will increase as Turnover Action is not required.
  • Cost for remodeling is not expensive.

Press Forming System(KIP)

This is a new Resin Forming system in which Vertical Type Press and Injection Machine are combined.
SP Mold Process (Multi Forming Process) which was developed by Sumitomo Chemical Co.,Ltd. is adopted.Integrated Molding Method of Surface and Base materials by use of Injection Press, instead of previous Extral Binding Process by separate molding, realized the great saving of labor and cost.This system is adopted as Lower Pressure and Lower Deformation method for following products.

  • Inner and Outer parts of automobiles
  • Large-sized industrial parts
  • Household utensils
  • Others

Special Features

  • Simultaneous forming of Base and Surface materials
  • Less forming process
  • Shorter forming cycle
  • Smaller equipment
  • Cost saving

Incidental Device

The operation can be automated with following equipments.

  • Resin Charging Device
  • Surface Material Feeder
