Prototyping/Co-Development

Fuji-Denshi US is Your Prototypes and Co-Developed Partner.

A complete prototyping and development solutions, for new or existing product solutions.


Trial Heat Treating is a establishes a baseline which aids in the troubleshooting process.


Including heating simulation, heat treatment sample production, cutting inspection, structure analysis, residual stress measurement, material analysis, and more.


Such as from carburization and flame hardening to high frequency or from furnace heating to high frequency induction heating.

Fuji-Denshi US Prototype, Co-Development Process:

Confirmation of work piece shape, heating specifications

Consideration of heating method; Quotation

Heating simulation (Optional)

Heating coil design, production

Prototype trial

Heat treatment sample, trial data submission

*Non-disclosure agreements can be arranged, as necessary.

Fuji-Denshi US Prototype, Co-Development Difference:

Equipment. Experience. Technology. Craftsmanship.

Choose the most suitable hardening machine from our wide range of processing units.

Using the appropriate output, converter frequency, and hardening machine for the work piece shape is vital. With our 15 unique converters and 30 hardening machines, Fuji Electronics Industry can handle any work piece.

Optimal Heat Treatment Proposal

The keys to high quality heat treatment are the heating coil and heating plan.

At Fuji Electronics, hardening machine design, coil design, and manufacturing all take place in one central location, facilitating rapid trial response.

Leveraging our decades of experience and state-of-the-art data measurement equipment.

Collecting highly accurate data is vital to prototyping and co-development. We work closely with customers to develop their products, drawing on our wealth of data from contract hardening and machine production.

Prototype > Mass Production > Equipment Manufacture

Coil and equipment specs differ by maker, making cross-trials difficult. At Fuji Electronics, development runs smoothly from prototype to mass production and equipment manufacturing.
