Our brand "Hi-Duc/Hi-Duc2" has been developed as a "material for large thick-walled molds" suitable for large die-casting molds. In particular, "Hi-Duc2" possesses strength comparable to cast steel, despite being a casting, due to improvements in graphite particle size and the addition of special elements. It has a uniform structure and hardness from the surface to the depth, preventing bending during hole processing. The successful refinement of graphite and the strengthening of the base structure have resulted in no internal defects. Moreover, its tensile strength and elongation are comparable to cast steel, providing various advantages unique to castings, such as "significant reduction in material costs," "shortened delivery times," and "reduced processing time due to improved machinability." *For more details about this material, please download and view the catalog.*

Are you struggling with reducing material costs for cast steel products? Since cast steel requires the installation of a large pouring system, it is fundamentally unable to achieve shape formation on the back side, leading to unavoidable machining operations. Our brand "Hi-Duc/Hi-Duc2" has been developed as a "material for large thick-walled molds" suitable for large die-casting molds, and particularly "Hi-Duc2" possesses strength comparable to cast steel due to improvements in graphite particle size and the addition of special elements, despite being a casting. This material allows for near-net shape formation on both sides, unlike cast steel, which can eliminate machining operations. "Hi-Duc/Hi-Duc2" offers various advantages unique to castings. ⇒ Please download the catalog to view more details about this material.

Do you have any of these concerns in the manufacturing process of cast steel products? ■ The need for a large riser results in longer post-processing (finishing) time... ■ The high pouring temperature leads to longer cooling times... ■ It is common to fill shrinkage with welding in cast steel, which takes additional welding time... Our brand "Hi-Duc/Hi-Duc2" has been developed as a "material for large thick-walled molds" suitable for large die-casting molds, and particularly "Hi-Duc2" possesses strength comparable to cast steel due to improvements in graphite particle size and the addition of special elements, despite being a casting. With this material, the amount of riser required is less compared to cast steel, allowing for a reduction in the finishing process. The pouring temperature is lower than that of cast steel (approximately 1550° to 1300-1400°), which leads to shorter cooling times. Furthermore, the welding process to fill shrinkage can also be eliminated. "Hi-Duc/Hi-Duc2" offers various advantages unique to castings. ⇒ Please download the catalog to view more details about this material.

Are you experiencing machine troubles due to chips in steel casting manufacturing? Since cast steel has a low carbon content, it has the property of producing chips that are difficult to break. This is especially true during hole processing with drills or surface machining with mills, where there is a high possibility of chips getting clogged, leading to concerns about lost processing time. Our brand "Hi-Duc/Hi-Duc2" has been developed as a "material for large thick-walled molds" suitable for large die-casting molds. In particular, "Hi-Duc2" has strength comparable to cast steel, despite being a casting, due to improvements in graphite particle size and the addition of special elements. This material contains a certain amount of carbon, which gives it the property of producing chips that are easier to break, thereby reducing the occurrence of clogging and machine troubles like those seen with cast steel. If you have such concerns at your site, please download our catalog to learn more about this material!

Our Yamanashi factory is a mass production facility for large lot items, primarily producing air conditioning parts, automotive parts, and industrial machinery parts using two high-speed casting lines. The castings for mass-produced parts not only require shape accuracy but also have a significant impact on the production efficiency of the processing plants at the delivery destinations due to even the slightest variations in material and hardness. These variations can greatly affect processing costs and finishing accuracy, and since they are incorporated into machinery as components, they also influence the performance and lifespan of the manufacturer's products. The achievements of our castings, which are still in operation as key components in millions of air conditioners and refrigerators worldwide, are a testament to their high precision and quality. 【Features】 ■ Produced on two high-speed casting lines ■ High precision and high quality ■ JIS G5502 certified, ISO9001 certified *For more details, please refer to the materials.
