We would like to introduce our 'Graphite Screw (TTST)' made from isotropic graphite materials that we handle. It is suitable for mechanical joining of graphite components, and we accept orders in units of one for each size. Additionally, you can specify the nominal length (underhead length) as an option. Since graphite (carbon) does not have standard sizes or fixed lengths like metals, we cut it from artificial graphite block materials with a black skin and finish it to the specified shape and dimensions. Please contact us when you need to place an order. 【Specifications (partial)】 ■ Material: Graphite CIP material (isotropic graphite) with carbon content of 99.9% or higher ■ Standard sizes - M6×1.0 Nominal length (underhead length): 45mm - M8×1.25 Nominal length (underhead length): 45mm - M10×1.5 Nominal length (underhead length): 45mm *For more details, please download the PDF or feel free to contact us.

The "Graphite Flat Plate (TTFP)" is a product made from isotropic graphite material that exhibits minimal variation in strength across all surfaces. Since graphite (black carbon) rarely comes in standardized or fixed sizes like metals, it is cut from artificial graphite block material with a black skin and finished to the specified shape and dimensions. The plate thickness is surface-ground, and the outer shape is finished by milling or vertical machining. Please contact us for inquiries. 【Specifications (partial)】 ■ Material: Graphite CIP material (isotropic graphite) with carbon content of 99.9% or higher ■ Tolerances - Plate thickness: ±0.05mm - Outer shape: ±0.5mm ■ Options: Specification of dimensional tolerances *For more details, please download the PDF or feel free to contact us.

• Processing Contract

We handle "Graphite Round Bars (TTRB)" that are cut from artificial graphite blocks, chamfered, and finished into a round shape. Since graphite (carbon) rarely comes in standard sizes like metals, we cut it from artificial graphite blocks with a black skin and finish it to the specified shape and dimensions. Dimension tolerance specifications are also available as an option. We handle each size on a per-piece basis, so please contact us first. 【Specifications (partial)】 ■ Material: Graphite CIP material (isotropic graphite) with carbon content of 99.9% or higher ■ Finish: Centerless finish ■ Tolerance ・ Outer diameter: ±0.05 ・ Length: ±1.0 *For more details, please download the PDF or feel free to contact us.

• Contract manufacturing

The "Tire Battery (R)" technology combines the creation of positive and negative electrode materials and conductive materials from the thermal decomposition components of used tires with processing and production techniques for carbon materials. As a result, we have established a technology for manufacturing low-cost, high-capacity batteries using used tires as raw materials. 【Features】 ■ Clarification of technology for low-cost manufacturing ■ 30% to 50% of used tires are electrode materials ■ Remaining components can be reused as terrestrial resources or energy sources ■ Negative electrode materials made from 100% tire raw materials have been developed *For more details, please refer to the PDF document or feel free to contact us.

• Secondary Cells/Batteries

We would like to introduce our "CFRP (Carbon Fiber Reinforced Plastic) products." We mainly handle CFRP, also known as dry carbon, which is produced using the "autoclave method" or the "vacuum bag method." Prepreg sheets are stacked in a mold and formed, with several atmospheres of pressure applied in a high-temperature furnace to cure the resin. After that, trimming and drilling are done to achieve the specified shape. *For more details, please refer to the PDF document or feel free to contact us.

• Other polymer materials

We would like to introduce our "C/C Composite (Carbon Fiber Reinforced Carbon) Products." This is a composite material made of carbon fibers and carbon (or graphite). It is used in rocket nozzles, turbine rotors, brake materials for high-speed vehicles and aircraft, and melting crucibles, among others. It has superior mechanical properties compared to graphite CIP materials and can withstand high temperatures like graphite. *For more details, please refer to the PDF document or feel free to contact us.
