Press dies & Method development

In the Press dies & Method development business, we have proposed a new construction method development using ZENFormer, ZENFormer nano.

We propose a significant man-hour reduction in the use of high precision press.

We can consistently processing to delivery from the purchase of material.
Available upon contract processing also happily in semi-finished products and prototypes.
Equipment sales in conjunction to the processing content and corresponding to meet the customer's needs is possible.

We developed the servo press machine of high precision and high efficiency of the world's highest level.
We proposed the new method development and man-hour reduction plan due to the high precision servo press.
Not only sale of press machine, can be manufactured prototypes and mass.

Case of two-stage cycloid gear molding by cold forging one step

Product	Decelerator for automotive variable intake system

Focused quality	Profile of line of two-stage cycloid gear, Concentricity between the two-stage gear, Cylindrical degree by the gear 3-stage surface

Mass production line	By utilizing the high-precision parallel pressurization and the micron bottom dead center accuracy of ZENFormer, it molds two-stage cycloid gear from ring blank by cold forging one step.

Result	Repeatability of the contour(a few micron level), Product strength improved by work hardening, Cost reduction

The case of shear by double-acting up and down simultaneously molding

Product	Tape feeder sprocket for semiconductor chip mounter

Focused quality	The concentricity between the tooth bottom and the center reference hole is smaller than 10μm.

Mass production line	Taking advantage of the double-acting slide of ZENFormer, it pulls tooth dies simultaneously up and down.

Result	It has achieved the concentricity smaller than 10μm in the high productivity press working.

Case of Laminate processing between different materials, different shapes

Product	Angle sensor for vehicle electronic throttle valve, accelerator pedal, exhaust gas recirculation valve, etc.

Focused quality	Position accuracy, Straight angle, Joint strength between magnetical laminations.

Mass production line	Laminating magnetic steel sheets and non-magnetic steel sheets alternately, and high accuracy the gap of the magnetic part.

Result	It has achieved the complex hollow three-dimensional structure by different materials in the high productivity press working.

Case of Cross-laminating of oriented magnetic steel sheets

Product	Automotive battery current detection sensor

Focused quality	Step accuracy of the left and right of the slit

Mass production line	Laminating of oriented electromagnetical steel sheets to be orthogonal in the rolling direction for each one.

Result	By to be orthogonal for each one and to laminate accurately electromaginetical steel sheets: it is low cost but it has insulating layer of high hardness that hurts significantly mold, it has achieved to ensure the magnetic properties and a significant material cost reduction compared to the upscale non-oriented magnetical steel sheet.

Case of high precision plane overhang by double-acting molding

Product	Metal separator for fuel cell

Focused quality	Uniform overhang height accuracy and flatness in the entire flow path

Molding process	Restrainting a large area thin plate entirely uniformly by parallel control of the outer with double-acting ZENFormer, confining, and molded overhanging the entire flow path with a high accuracy by centralized load of independently driven inner.
