Various Kinds of Heat-Treatment Devices

“Simple and Lasting”
—the basis of Monozukuri of Itsuwa

The feature of the Itsuwa’s heat-treatment devices is in the design that pursues the limit of the lightness and thinness.
Our purpose of lightening is to reduce the load of human and equipments as much as possible, and its final aim is to decrease environmental load.
Moreover, we stick to details of the design in order to make the device more durable in parallel with promoting lightening, based on our know-how cultivated since more than 20 years ago.

【Heat-Treatment Devices】Heat-Resistant Casting Steel by Lost-Wax Investment Casting Process

“Lost-Wax Investment Casting Process”
brings out the maximum exquisiteness of our design.

Heat-treatment devices repeat expansions and shrinkages by the heat, so the joint created by the welding process could be the cause of shortening their lives.
Therefore, “Lost-Wax Investment Casting Process” is the best way to produce the heat-treatment devices because the process enables us to cast the complex figure in a body, precisely and smoothly.
This process makes it possible to materialize our thin-walled design.

Our group factory in Dalian, China has had many experiences of manufacturing thin-walled and big-sized devices that are said to be difficult to be cast in a body.
We always work in close cooperation with the factory. We consistently has the manufacturing, quality, and due date under perfect control, so we can comply with the wishes of the customers at once.
We’re preparing for not only general heat-resistant casting steels but also our original high-Nickel materials. We’re able to suggest better ideas by choosing suitable materials to the heat-treatment conditions of the customer.

【Heat-Treatment Devices】Sand Mold Heat-Resistant Casting

We eliminate every over-specification for your cost benefit.


※Larger photos are showed by a click.

Casting by using wooden molds enables us to lower the initial cost and to make the design changes easier.
While the accuracy and the casting surface become slightly rough, the process is still effective to manufacture large and heavy products such as trays.

Advantage of ITSUWA

Our design is featured by drastic elimination of over-specification.
We always suggest cheaper, lighter and more usable devices.

【Heat-Treatment Devices】Welding of Stainless Steel

High welding technique makes more complex shapes possible.


※Larger photos are showed by a click.

Making full use of skilled welding techniques and various machining methods, we can suggest products with more complex shapes.
Welding is the most suitable way to make prototypes and to manufacture specialized devices.
We also can design and manufacture wire-netting baskets of stainless steel.

The Advantage of ITSUWA
Combining lost-wax casting products and welding techniques enables us to create more long-lived devices with more flexibility.

Casting Parts

Enterprising spirit produces the global network that has the limitless possibility of “Monozukuri.”

Our casting network is globally expanding based on our group factory in China.
Entering into partnership with the traditional casting makers in England and Germany, we are now developing our ability to meet the customer’s needs of the wider area with introducing new technologies.
Adopting casting process as the first step of the manufacturing process makes it possible to dramatically save waste of materials and the man-hour for cutting.

Without considering industrial fields, we can deliver parts in any form such as materials themselves, complete shapes and assemblies at your request.

So please feel free to ask us, whatever the shapes and sizes.

Please make an inquiry from here.
