HPM-7 plastic mould Steel Hot rolled flat bar Thickness 10mm-100mm Width 200mm-710mm
HPM-7 plastic mould Steel block Usage: suitable for large& medium-sized and precision plastic mould and low-melting point alloy .
plastic mould steel block:
Characteristic: with good machining performance excellent polishing performance and hardenablity, high hardness and wear resistance, at the same time the cross-section of a larger size will enable a more uniform hardness.
