INTRODUCTION DIE & MOLD MACHINING When speaking of molds, there are different types in the world. For example: molds for plastic materials, sheet metal - cutting and forming, die - casting, rubber molding, blow molds, and forging molds. Within the mold industries there are also several defined spare parts that complete the mold structure. This great variety implies the machining process on a wide range of materials, such as pre-hardened steels, hardened steels, cast iron, aluminum for prototypal molds, stainless steels for manifold and hot runner parts, graphite and copper for electro-erosion processes. The abundant tools YG-1 offers are able to support the needs of the Die & Mold customers, whatever the material to be processed and the application to be implemented. 4 5

APPLICATIONS STEEL & PRE-HARDENED STEEL The Die & Mold industry makes use of different types of steels, according to the type of mold to be made. Normally they are divided into 2 families: - Hot work steels (molds for plastic injection, rubber, forging, die-casting) - Cold work steels (dies for shearing and plate deformation) In the latter type of molds, the use of cast iron is also frequent. Die & Mold industry needs a right partner to machine a wide range of different pre-hardened materials YG-1 can cover that demand, whatever the material, application or machine YG DRILL Experience the tremendous cost reduction and high standard of quality that our indexable drills provide. Our selection of chipbreaker geometries is ever growing and our carbide grades are providing you an easy choice.
