Characteristics of M333 Mold Steel
The main characteristics of M333 include excellent toughness and high hardness after quenching, which gives the mold a long service life; Excellent thermal conductivity reduces the cooling time of the mold and accelerates the production efficiency of the product; Mirror polishing effect saves production costs of polishing molds and reduces maintenance and repair time; High purity molds make electrical machining performance more convenient; Excellent acid resistance and corrosion resistance further extend the lifespan of the mold.
M333 plastic molds have better heat dissipation than general mold steel, effectively solving problems such as long mold opening time due to insufficient heat dissipation.
Application of M333 plastic mold steel
M333 plastic mold steel has a high-efficiency mirror effect, strong acid resistance, and is particularly suitable for audiovisual products; Laser discs are suitable for acidic and corrosive plastic molds, such as PVC cosmetic box molds.
M333 plastic mold steel hardness
Soft annealing to HB220. Hardness 48-50HRC.
