アステック入江 List of Products and Services

Our company conducts "resin plating recycling." We collect resin-plated products used in automotive parts such as front grilles and door mirrors, as well as faucets, and separate and recover the resin and valuable metals through a ferric chloride recycling system. Please feel free to consult us when needed. *For more details, please refer to the PDF materials or feel free to contact us.

• Other resource recycling

Our company is engaged in the sale of copper and nickel (powder and briquette manufacturing). We process difficult-to-handle recovered metals into easily manageable briquette (compressed solid) forms using the technology we have established, making them effectively usable as metal raw materials. Additionally, we offer various briquette processing services. 【Features】 ■ Processed into easily manageable briquette (compressed solid) forms using our established technology ■ Can be effectively utilized as metal raw materials ■ Capable of handling various briquette processing *For more details, please refer to the PDF document or feel free to contact us.

In our "Iron Chloride Liquid Recycling Business," we regenerate and recycle waste acids such as etching wastewater (waste iron chloride) and can individually separate and recover dissolved valuable metals (copper, nickel, chromium (chromium hydroxide), etc.). There are benefits to waste reduction through the recovery and re-resourcing of valuable metals from waste. Additionally, we also sell iron chloride liquid. We can adjust the concentration (Baumé) according to your needs, so please let us know. 【Features】 ■ Regeneration and recycling of waste acids such as etching wastewater (waste iron chloride) are possible. ■ Individual separation and recovery of valuable metals (copper, nickel, chromium (chromium hydroxide), etc.) dissolved in waste acids such as etching wastewater (waste iron chloride) are possible. ■ There are benefits to waste reduction through the recovery and re-resourcing of valuable metals from waste. *For more details, please refer to the PDF document or feel free to contact us.

Our company is engaged in the manufacturing and sales of iron powder. Iron powder is produced by collecting airborne dust generated during the converter process at steel mills using dust collection equipment, and manufacturing it from the coarse dust recovered from the collected dust. Due to its high bulk density and low specific surface area, it has a mild reactivity for chemical reactions and is mainly used for stainless steel cutting and heavy liquid separation. 【Features】 ■ High carbon concentration and excellent hardness ■ Spherical particles with excellent flowability ■ High bulk density and low specific surface area ■ Mild reactivity for chemical reactions *For more details, please refer to the PDF document or feel free to contact us.

Introducing our FM (Fine Metal) business, which is attracting attention from various industries as a process for the regeneration treatment of ferric chloride. We use iron powder produced by our company as a reducing agent for the etching wastewater generated from steel sheets (lead frames) in the IC industry and electronic components industry. We separate and recover valuable metals (such as nickel and copper) from the wastewater, while regenerating ferric chloride (II) and (III). 【Business Overview】 ■ Manufacturing and sales of iron powder ■ Recycling business for ferric chloride solution ■ Sales of copper and nickel (powder and briquette production) ■ Resin plating recycling *For more details, please refer to the PDF materials or feel free to contact us.

Astech Irie Co., Ltd. was established in 1901 (Meiji 34) when the government-operated Yawata Steel Works began operations in Yawata Village, Fukuoka Prefecture, marking the first step in establishing Japan's steel industry. About ten years later, in 1910 (Meiji 43), the company started its operations as a contractor for the Yawata Steel Works. Since then, the company has changed its name from Irie-gumi to Irie Kōsan, and then to Astech Irie, expanding its business while focusing on the iron industry, and has now also ventured into the fields of environment and recycling. 【Business Overview (Excerpt)】 ■ Iron Business - Steelmaking (refining, slag treatment, refractory construction) ■ Derived from the Iron Business - Fine ceramics precision processing ■ Environment & Recycling - Manufacturing and sales of iron powder and ferric chloride solution *For more details, please refer to the PDF materials or feel free to contact us.

The "Cleaner (Conveyor Belt Cleaner)" is a belt cleaner that can accommodate various sizes of belt conveyors, allowing for the selection of materials and contact widths suitable for the application based on the conveyed items and the shape of the belt conveyor. Conventional belt cleaners have a scraping part and plate shape with a width of 100 to 150 mm and a thickness of 5 mm, which leads to uneven contact with the belt conveyor, making scraping ineffective and resulting in material spillage. Additionally, adjusting and replacing the belt cleaner has been cumbersome. Our product addresses all of these issues. 【Features】 ■ Small segmented chips closely follow uneven surfaces ■ Excellent wear resistance with ceramic material ■ Partially flexes to instantly avoid protrusions ■ Superior elasticity with urethane rubber ■ Easy installation *For more details, please refer to the catalog or feel free to contact us.

The "D-TEC PILE Method (Rotary Driven Steel Pipe Pile Method)" is a construction method that allows for the management of reaching the bearing layer for all piles by measuring the rotational torque. Steel pipe piles are used to penetrate the ground and prevent differential settlement of buildings on soft ground. By attaching circular wings to the tip of the steel pipe piles and giving them a spiral shape, construction time can be shortened, and the bearing capacity can be increased, thereby reducing the number of piles required. Additionally, for the joints, a plug-type joint that does not require on-site welding has been adopted, achieving improvements in quality and operability. 【Features】 - Low noise and low vibration among foundation reinforcement methods - No residual soil generated - Management of reaching the bearing layer for all piles is possible by measuring the rotational torque - Stable quality is achieved by integrally molding the tip components in cast steel *For more details, please refer to the catalog or feel free to contact us.
