1 PLASTIC MOLD STEELS

2 PROIDING UNIQUE SPECIALTY STEELS FOR TODAY'S PLASTIC MOLD TOOLING BÖHLER Mold Steels have been designed, developed and refined specifically to provide the optimum solution for the most demanding mold tooling applications in today's expanding plastic mold market. A number of unique products have been successfully introduced recently in answer to increasing market demands. These steels provide advantages and benefits to mold makers and molders worldwide compared to traditional mold steel grades. A plastic product is only as good as the mold and the mold steel from which it is produced. Special BÖHLER Quality Levels:...ESR Remelted...acuum Remelted...PM, Powder Metallurgy For the Moldmaker, we strive to provide you with the best steel available together with a comprehensive technical application consulting service. For today's Plastic Processor, our goal is to provide the best mold performance, overall economy and profitability.

3 TOOL MAKERS REQUIRE THE BEST MACHINABILITY You as a toolmaker want to have Economic manufacturing, especially if a high degree of machining is necessary Best polishability Uncomplicated, consistent manufacturing process Optimum grindability Material Properties Excellent machinability High cleanliness Steel of consistent quality Homogenous material properties MANUFACTURERS REQUIRE THE HIGHEST QUALITY You as a plastic processor want to have Long tool life Short cycle times Resistance to corrosive influences, resulting in less service and maintenance Consistent tool quality Assured by High wear resistance Best thermal conductivity Corrosion resistance Best hardness and toughness properties and compressive strength
