PR message
We have an integrated production system for pig iron casting products.
We are able to provide a wide range of services such as wood mold production, casting, heat treatment, painting, machining (NC lathe machining, turning machining, machining), etc.
We can provide a wide range of services such as
We handle gray cast iron (materials FC200 to FC350) and ductile cast iron (materials FCD400 to FCD700).
We have a wide range of products for industrial machinery parts, ship machinery parts, construction machinery, machine tools, public facilities, etc.
We strive to create optimal castings by making full use of casting simulation.
We propose low-cost, high-quality manufacturing methods that meet our customers' needs.
We also use a 3D scanner to quickly and accurately measure dimensions, and we are able to convert errors between drawings and the actual product into data.
We guarantee the accuracy of our products.
Product weight: 30 kg to 1.5 t. Other weight can be handled by our partner companies.

<Inspection capability
Inspection of internal defects using ultrasonic waves
→Internal flaws are determined by ultrasonic flaw testing method.
Inspection of external defects by color check
→The penetrant flaw test (color check) is used to determine whether surface defects on the casting surface and machined surface are acceptable or not.
Analysis and inspection of composition, flow, and solidification using various equipment.
→Daily control of each material component using emission spectrophotometers to maintain component quality.
→Use casting simulation software to predict in advance the flow of hot metal and the solidification process.
→The casting simulation software is used to predict the flow and solidification process in advance to reduce the risk of defects and to make improvements.
Quick and easy-to-understand dimensional measurement by 3D scanner
→Æ Perform 3D visualized dimensional shape inspection by comparing nominal drawing CAD data and scanned mesh data.
