Using machining in addition to combined hot/cold forging,
Yamaco strives to manufacture possibilities from the impossible.
The strength behind Yamaco is a combination of hot forging and cold forging technologies.
Using time-tested techniques and ingenuity cultivated since its founding,
Yamaco strives to transcend the founding ideas of manufacturing in an effort
to discover new possibilities for higher accuracy, higher quality, quicker delivery, and lower costs.
Combined hot/cold forging (precision forging)
Using various materials in various ways
High-precision forming, and the pursuit of new materials.
In pursuit of cutting-edge technology and more possibilities in precision forging.
When discussing forging, iron is a common topic.
Due to its high strength, iron is often used for important parts such as drive system components.
With an eye toward a wide variety of advanced materials, Yamaco is dedicated to developing next-generation technology.
In heat-based hot forging, a complicated shape is formed by stamping.
Yamaco takes this one step further and combines hot forging with cold forging, which requires greater accuracy,
to create a product that requires less processing.
The true value of Yamaco is evidenced in its combined technology in addition to forging,
allowing products to be created by taking advantage of machining technology as well.
1.Aluminum forging technology
Reducing the weight of automotive components is an essential aspect in improving fuel economy.
This makes aluminum particularly suitable as a substitute for casting or die-casting materials
that would otherwise not be strong enough. Yamaco continues to look at the possibilities of
hot forging aluminum alloy, which offers strength similar to that of iron.
2.Titanium forging technology
Titanium is a lightweight, high-strengthmaterial with excellent corrosion resistance.
This material is expected to continue being widely used in various fields, including
in the medical field for artificial joints, and in the aviation field for aircraft engine disks
and shafts requiring a high level of reliability. Recognizing this potential,
Yamaco quickly adopted titanium as a new material and set about hot forging,
cold forging, combined hot/cold forging, and machining titanium products.
3.Cobarion (cobalt alloy) forging technology
Cobarion is an alloy with a low nickel count, making it suitable for medical-related products
that come into contact with the human body. In addition to use in the biomedical field such
as for artificial bones and joints, Cobarion can also be found in ornamental goods industries,
giving a unique shine to luxury wristwatches and rings.

4.Inconel and Hastelloy forging technologies
Inconel—a nickel-based alloy—is used for industrial turbines and other components used
in harsh environments, such as in aerospace and space industries for its excellent
high-temperature characteristics and resistance to erosion. The difficulty in cutting this alloy
means it must be processed using forging technology (hot or cold) with less processing.
5.CFRP forging technology (patent pending)
Carbon fiber reinforced plastic (CFRP) is a new material being used in place of metal materials.
CFRP is being increasingly adopted for various products due to its light weight and high strength.
Yamaco is able to adapt its plastic processing technology to produce CFRP products
in a wide variety of complicated shapes.

Using various materials in various ways A production system that reliably covers everything
from die design to production as well as forging and machining.
Yamaco incorporates 3D CAD/CAM designing for creating product designs with complicated shapes, which are then used in-house to create dies.
Through its streamlined production method covering design to forging and machining,
Yamaco is able to create products with short delivery times with less processing and at reduced cost.
Yamaco System
1.
3D CAD/CAM designing
Yamaco’s dedicated operators use 3D CAD/CAM designing to develop the latest die designs. This enables creation of efficient, high-quality forging dies. The process also makes it possible to create a 3D model after a preliminary review.
2.
Die creation
Yamaco creates optimized high-speed processing data using 3D CAD/CAM software for a finished product with no precision polishing and minimal waste, allowing for short delivery times to customers.
3.
Steel cutting
By introducing the latest high-speed automatic press cutting machines, Yamaco has improved forging yield through increased cutting precision. This allows for a reduction in overall production costs.
4.
Steel heating
In hot forging, components are heated to the temperature required for the material. This allows large materials to be made into complicated shapes.
5.
Hot forging
Using a high-speed air stamp hammer, the material heated to a high temperature is struck repeatedly to create the desired product shape. The structure of products tempered at high temperatures becomes incredibly dense, allowing for miniaturized structures to embody excellent strength characteristics.
6.
Cold forging
Unlike hot forging, cold forging involves materials not heated beyond room temperature. This allows for highly precise manufacturing with products being processed into dimensions and shapes similar to the finished product. Yamaco uses specialized hot/cold combined forging techniques.
7.
Machining
In addition to processing forged material, Yamaco has access to high-precision machining equipment. Yamaco also has a rolling machine capable of mass-producing specialized screws and similar products. This integrated production system—from design to machining—is one of Yamaco’s greatest advantages.
8.
Inspection / Quality control
The ability to work from design to production ensures improved consistency through 3D data in addition to guaranteed quality. This allows Yamaco to ensure improved quality even before the start of manufacturing.
