• Testing Equipment and Devices

We handle "simple casting devices." After arc melting, you can easily cast bulk materials by simply pressing the suction start button. There is a gap adjustment mechanism at the bottom of the mold, allowing for suction adjustment. Equipped with a video camera, operations such as casting can be performed without directly viewing the arc. 【Features】 ■ Easily cast bulk materials by simply pressing the suction start button after arc melting ■ Gap adjustment mechanism at the bottom of the mold ■ Suction adjustment is possible ■ Equipped with a video camera ■ Operations such as casting can be performed without directly viewing the arc *For more details, please refer to the external link page or feel free to contact us.

• Casting Machine

We handle "differential pressure casting equipment." By driving the bottom of the mold at high speed, molten metal that has been arc melted in an Ar gas atmosphere is cast into a water-cooled mold, resulting in rapid cooling and solidification. Since there is no crucible, there are no impurities from the crucible, allowing for high-purity melting, and it is suitable for casting high melting point materials that exceed the heat resistance temperature of the crucible. 【Features】 ■ High cooling rate - Purification of bulk amorphous metals and nanocrystalline materials ■ Heat source is an arc - Heating temperature in the thousands of degrees - No crucible, resulting in purer cast samples than high-frequency methods ■ Suction source is a cylinder - Less gas entrapment and fewer casting defects *For more details, please refer to the external link page or feel free to contact us.

• Casting Machine

We handle the "Converge Mill." The media balls and samples introduced into the rotating container are redirected by guide vanes shaped like spatulas, causing them to fly towards the opposite wall. These balls collide with a powder layer formed by the clearance between the guide vanes on the wall and the container, resulting in the production of extremely contamination-free fine powdered samples. 【Features】 ■ High efficiency in energy addition and good thermal dispersion ■ High processing speed due to the uniaxial rotation center ■ Reduced wear particles as a powder layer forms on the inner wall of the container ■ High powder recovery rate due to heat generation suppression and scraping effect *For more details, please refer to the external link page or feel free to contact us.

• Crusher
• Fine grinding machine

We handle "multi-stage crushing devices." After vacuum evacuation, inert gas is replaced in the dissolution chamber, and the metal is melted through high-frequency induction, which is the first stage of crushing with gas. Next, the metal, atomized into a mist, collides with a high-speed rotating disk that supplies refrigerant in the second stage. This multi-stage process of crushing and rapidly cooling the dissolved samples has advantages for producing fine powders with non-equilibrium structures such as amorphous and nanocrystalline materials. [Features] ■ Multi-stage crushing and rapid cooling of dissolved samples ■ Advantages for producing fine powders with non-equilibrium structures *For more details, please refer to the external link page or feel free to contact us.

• Crusher
• Fine grinding machine

We handle "Gas Atomization Equipment." By creating a differential pressure between the melting chamber and the spray chamber, and by raising the stopper, molten metal is dropped downward. High-pressure gas is then sprayed onto the molten metal to produce spherical metal powder particles. After vacuum evacuation, the powder is rapidly cooled and solidified in an inert atmosphere, allowing for easy powdering of samples with strong oxidizing properties that cannot be achieved with water atomization. 【Features】 ■ Rare earth magnet powder for injection molding (MIM) - Samples are collected without exposure to the atmosphere in an inert gas atmosphere using a glove box. ■ Powder for 3D printers - We provide spherical powders for 3D printers, including aluminum powder, titanium powder, cobalt-based powder, and Inconel powder. ■ High melting point sample powder - By heating samples up to 2000°C, it is possible to powder high melting point samples like pure iron. *For more details, please refer to the external link page or feel free to contact us.

• Powder Molding Machine

We handle "Liquid Rapid Cooling Devices." After vacuum evacuation, inert gas is replaced in the dissolution chamber, and molten metal is sprayed onto a rotating roll by gas pressure, rapidly solidifying to produce ribbon-shaped samples such as amorphous alloys, metallic glasses, and nanocrystals. We also accept tests using demo units. 【Overview of Sample Test Commission】 - The test period is one day, with up to three tests possible in a day. - High-speed cameras are used to capture the phenomena. - The recorded footage is provided as still images. - We can accommodate various materials, including magnetic materials and battery materials. - Delivery times can be discussed, ranging from a minimum of one week to one month. (Please note that it may take longer during busy periods.) *For more details, please refer to the external link page or feel free to contact us.

• Cooling system

The "Single Roll Type Atmosphere Liquid Rapid Cooling Device" is a device that uses an induction heating method powered by a high-frequency oscillator. The molten metal, melted by high-frequency induction, is sprayed onto a rotating roll under gas pressure, rapidly cooling and solidifying to produce ribbon-shaped samples of amorphous metal, metallic glass, and nanocrystals. 【Features】 ■ Samples are rapidly cooled and solidified at a cooling rate of 100,000 to 1,000,000 °C per second ■ Produces metal thin strips approximately 1 to 20 mm wide and about 40 μm thick (objective) ■ We accept tests using our in-house demo machine *For more details, please download the PDF or feel free to contact us.
