Plastic Mold Steels Providing Unique Specialty Steels for Today's Plastic Mold Tooling

PLASTIC MOLD STEELS PROVIDING UNIQUE SPECIALTY STEELS FOR TODAY'S PLASTIC MOLD TOOLING

BÖHLER Mold Steels have been designed, developed A number of unique products have been successfully and refined specifically to provide the optimum solution for introduced recently in answer to increasing market demands. the most demanding mold tooling applications in today's These steels provide advantages and benefits to mold makers expanding plastic mold market. 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

...... Vacuum 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. TOOL MAKERS REQUIRE THE BEST MACHINABILITY

You as a toolmaker want to have Material Properties

Economic manufacturing, especially if a high Excellent machinability degree of machining is necessary

Best polishability High cleanliness

Uncomplicated, Steel of consistent quality consistent manufacturing process

Optimum grindability Homogenous material properties

MANUFACTURERS REQUIRE THE HIGHEST QUALITY

You as a plastic processor want to have Assured by

Long tool life High wear resistance

Short cycle times Best thermal conductivity

Resistance to corrosive inﬂuences, resulting in less Corrosion resistance service and maintenance

Best hardness and toughness properties Consistent tool quality and compressive strength MOST FREQUENTLY USED STEELS
