PLASTIC MOLD STEELS

PROVIDING 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

.....................................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.
