M333 plastic die steel properties
The main features of M333 are: excellent toughness and high hardness after quenching, so that the mold has a long life; Excellent thermal conductivity, reduce the cooling time of the mold, speed up the production efficiency of the product; The mirror polishing effect saves the production cost of polishing mold and reduces the maintenance and repair time; High purity mold, so that the electrical processing performance is more convenient; Excellent acid and corrosion resistance to further extend the life of the mold.
The heat dissipation of M333 plastic mold is better than that of general mold steel, which effectively solves the problems such as too long opening time due to insufficient heat dissipation.
M333 plastic die steel use
M333 plastic die steel has a high performance mirror effect, strong acid resistance, especially suitable for audio and video products; Laser records are suitable for acidic, corrosive plastic molds, such as PVC cosmetics box molds.
M333 plastic die steel hardness
Soft annealed to HB220. Hardness 48-50HRC.
