Established Tooling Applications


— Serial Tooling ( Plastic Injection )•Typical EOS MaragingSteel MS1•Conformal Cooling often used•Benefits in better part quality, process control, shorter cycletimes and longer lifetime of the mold

— Vulcanisation•Typical EOS MaragingSteel MS1•reduced cycle times due to tempering channels
