Thermoplastic blowing mold
Main parts of heavy-duty mold
Structural fabrications
Usually used for manufacture of television casing, washing machine, refrigerator
Inner casing, and water-pot.

Characteristics:
Pure steel quality due to vacuum degassing treatment
The screwing die is formed by forging, and the flat steel and round steel are formed by rolling at a high ratio of deformation. It is compact in structure, suitable for making the plastic molds requiring Polish or etch machining.
Porosity occurs if the thickness of rolled sheet is higher than 120mm. It is not recommended for use to the molds with mirror polishing requirements.

Plastic mould steel P20/618/PDS3/2311 Precipitation hardened mirror surface steel. Steel for high-rigidity mirror die steel
Pre-hardened to deal with the state to supply 37-43HRC, and suitable for direct processing tool steel mold polishing, cutting performance can be manufactured with the same process rather NAK80 steel.

Can heat to 45-48HRC, made up of steel NAK80 shortcomings can not be combined with hardware to meet the requirements of multi-purpose
