A manufacturing lifeline that supports advanced manufacturing industries

The materials business that produces foundational components through the integration of excellent materials and technologies for all fields including automobiles, machine tools, precision machinery, construction machinery, transportation equipment, industrial machinery, and electrical and electronic components. As a leading company in the advanced components industry that performs cast iron and steel, precision casting, die casting, and steel processing, the Kawakin Holdings Group will continue creating innovative components into the future.

Cast Steel and Cast Iron

Advanced casting technologies flexibly meet any shape and quality requirements.

Our high-quality products are manufactured using casting technology that can create any shape from any material including ordinary cast steel, alloy cast steel, ordinary cast iron, ductile cast-iron, and austenitic cast-iron (Ni-resist). They are broadly used in wide-ranging applications and have been highly rated in industrial circles.

Since its foundation, Kawaguchi Metal Material has used advanced technological capabilities to manufacture high-quality cast products of various shapes using a variety of materials for use in fields including industrial machinery, construction equipment, vessels, civil engineering, and construction.
The high degree of completion of its products has attracted particular attention in the development and manufacture of large components used for large-scale construction machinery, vessels, and structural steel castings.

Precision Castings and Die Castings

High-quality precision casting technologies lead global standards.

The lost-wax process offers high dimensional accuracy, making it ideal for mass production of products with complex shapes, while nano casting, a type of semi-solid die casting method, achieves excellent mechanical properties and pressure resistance. With these and other techniques, we are a leader in industry standards for high-precision and high-quality precision casting technology.

Hayashi Lost-Wax Industries is a pioneer in the overseas expansion of business in the precision casting industry. The company sells high-quality, precision castings manufactured at its production base in Dalian, China. Its products are widely used in automobiles, industrial machinery, medical equipment, and other applications. The company is reinforcing its production site and synergies to meet increasingly sophisticated and diverse needs.
