One notable point about the DED method is the ability to manufacture molds that can bond dissimilar materials, which was difficult with conventional processing methods. For example, it becomes possible to coat areas that experience severe wear with a steel type that has excellent wear resistance. Additionally, since the surface temperature of casting molds must be kept from being too high to avoid reducing the yield of cast products, continuous cooling of the molds is necessary. By using a highly thermally conductive steel type for the interior of the mold and coating the surface with tool steel, the cooling effect can be improved from a physical performance standpoint. **Features** - It becomes possible to coat areas that experience severe wear with a steel type that has excellent wear resistance. - By using a highly thermally conductive steel type for the interior of the mold and coating the surface with tool steel, the cooling effect can be improved from a physical performance standpoint. - Improved yield of cast products and increased productivity can be expected. *For more details, please refer to the PDF document or feel free to contact us.*

The DED system owned by Fujik Corporation has two powder supply tanks, allowing for the simultaneous supply of two types of materials. This enables the continuous variation of the material ratio during the manufacturing process. Thanks to this feature, it is possible to combine different materials within a single component, making the realization of gradient functional materials feasible. [Features] ■ Continuous variation of material ratio during manufacturing ■ Realization of gradient functional materials possible *For more details, please refer to the PDF document or feel free to contact us.

The "LASERTEC 65 DED hybrid" is a metal 3D printer capable of automating the welding process. In conventional TIG welding, manual work is required, which takes a significant amount of time, and in recent years, the shortage of skilled welders has become a problem. TIG welding that takes 10 hours by hand can be completed in just 1 hour using laser welding with this product. Welding area, bead size, heat input, and other parameters can be controlled numerically through programming, eliminating the need for rework due to insufficient welding, and allowing for welding on the machine without the need for setup changes. 【Features】 ■ TIG welding that takes 10 hours by hand can be done in 1 hour ■ Welding area, bead size, heat input, etc., can be controlled numerically through programming ■ No rework due to insufficient welding ■ Welding on the machine eliminates the need for setup changes *For more details, please refer to the related links or feel free to contact us.

This document provides detailed information on the applications and cutting conditions of "tungsten" as taught by mold makers. Generally, die steel is used as the material for molds used in casting and shell molding, but why tungsten for molds? It presents proven applications and success stories that demonstrate how its adoption can significantly extend the lifespan of molds. It also introduces two main cutting conditions and examines whether machining-specific marks can be polished with grinding stones. We encourage you to read it. 【Contents】 ■ Why tungsten for molds? ■ Applications and success stories ■ Cutting conditions ■ Verification ■ Summary *For more details, please refer to the PDF document or feel free to contact us.
