Technical Center: The Nerve Center of Ahresty’s Technology Development Efforts

Pursue and Advance MONOZUKURI

Ahresty is engaged in continuous research and development efforts to develop new materials and production methods, staying one step ahead of customer needs that demand advances in die casting technology.
The Technical Center is the nerve center of our technology development efforts. It also functions as a support base, helping us to achieve consistent production quality at all of our production facilities worldwide.

Head Office and Technical Center (Toyohashi, Aichi)

2,250 ton casting machine (for testing purposes)
Our Technical Center has a heavy-duty casting machine for testing purposes, and conducts analyses and assessments of die cast products under various conditions.

Material property assessments carried out by various testing machines
Our Technical Center is equipped with a full range of testing machines for evaluating the mechanical properties of castings, including tensile, impact/shock and fatigue testing machines.

Observation and analysis using electron microscopes
We use electron microscopes to observe surface aspects and conduct elemental analyses at high magnification, helping us to determine the causes of various phenomena, and leading to improvements in quality.

Excellent design and analysis setup
We have a full complement of over 80 design engineers who make speedy proposals and develop solutions to match the needs of our customers.

Optimal shape achieved through CAE
By utilizing CAE to carry out molten metal flow and solidification analyses and assessments, we seek to achieve optimal manufacturing and productivity.

High-productivity manufacturing process support framework
With the support of our Technical Center, we aim to achieve the same level of quality and high-productivity manufacturing processes globally.

Setting optimal production conditions
By ascertaining and managing characteristic factors such as casting pressure, time and speed of pressure increase, we work to ensure optimal production conditions at our manufacturing facilities.

Production method development: ーAhresty’s own, self-developed method of aluminum die casting―

Ahresty is working every day to research and develop new production methods and technologies that will enable greater quality and higher efficiency in production.

High GF Casting

Ahresty’s casting method enables T7 heat treatment and improves on the elongation performance (0.2% yield strength) demanded for automobile body components, etc.
Increasing the level of vacuum inside the cavity (in comparison with low-pressure die casting) means that Ahresty’s method can also be applied to the production of higher quality, large-scale thin wall casted products.

［Components to which this method can be applied］
Chassis, body and EV/FCV case components

New Injection Casting

Achieving a whole new class of quality that exceeds conventional expectations for die cast products
In comparison with regular die casting methods, Ahresty’s casting method creates products with greatly superior mechanical properties. Ahresty was awarded the Minister of Economy, Trade and Industry Prize for this casting method in 2004, as a proprietary production method that has greatly expanded the scope of applications (with a primary focus on undercarriage/ suspension-related products).

［Components to which this method can be applied］
Suspension components, engine and transmission mountings, brake components

Pore Free Die Casting

Improved strength, welding and hardness solved by heat treatment (T6)
This method of casting replaces the air in the cavity with oxygen, thereby greatly reducing gas defects. Application of this die casting method to automobile components enables us to contribute to reducing weight and respond to tougher fuel efficiency requirements.

［Components to which this method can be applied］
Various mounting and member components, brackets, pressure-resistant parts
