Description
DIN 1.***8 Plastic Mould Steel 1, Features:
1) Use vacuum degassing method to refine, obtaining lower content
of impurities and gas;
2) Ultrasonic examination on steel, and applicable to fabricate
mirror-polishing die (if rolling plate exceed **0mm, not recommend
to fabricate mirror-polishing die);
3) Pure steel, capable of being etch machined, with good
performance in electric discharge machining;
4) The steel is of good nitriding performance, and its surface
nitridng after hardening can significantly extend the service life
of die. 2, Supply Condition: Hardened, Tempered, Hardness
**0~**0HBS, **0~**0HBS. 3, 1.***8 Plastic Mould Steel of
Applications:
Injection die, extrusion die, compression mold, blowing die and
absorbing mole that are applicable to all kinds of plastics, are
commonly used as dies for housings of such products as air
conditioner, washing machine, computer monitor, printer and fax
machine which have higher requirements on the smoothness of
surface.
