Compared to cast steel, it is possible to shorten post-processing and cooling time, and to eliminate the need for filling work through welding.

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.

basic information

**Features of "Hi-Duc/Hi-Duc2"** Due to its uniform structure and hardness from the surface to the deep layer, there is no bending during hole processing, and the successful refinement of graphite and strengthening of the base structure result 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." **About Sugiyama Co., Ltd.** The casting industry occupies a very important part of the material sector within all industrial structures. At our Fuji factory, we primarily cast die holders for die-casting molds, as well as castings for resin molds, press molds, and various industrial machine parts. Our products are unique and can be cast into various shapes, accommodating a maximum product weight of 13 tons. Additionally, to meet our customers' further needs, we have an attached processing factory with 16 machining centers, both large and small. As a technical company that achieves high quality and rapid delivery through the full mold casting method, we have established an environment for integrated production from foam modeling to casting and machining, striving to create products tailored to our customers' needs.
