Application 1： Car lighting Systems

Requirement of Car-lighting mold - Large size range - Complicated structure - High polishing, Mirror polishing or Chrome-plating - Large production amount, require wear resistance

XPM VICTORY ESR for Car Lighting XPM VICTORY ESR

Peter Liu

XPM VICTORY ESR → Advantage ： - Suitable for large size, even >600mm - Pre-hardened, no need vacuum heat treatment - No crack risk during H+T - Faster production cycle -Save cost, low price, no H+T cost.

1.2343 VICTORY ESR 1.2083 VICTORY ESR → Disadvantage: - Not suitable for large size - Need Vacuum heat treatment - Crack risk during H+T - Long production time → Advantage: After H+T，Higher polishing ability, higher wear resistance

Vacuum Hardening Risk

Coarse grain size lead to tiny cracks

Peter Liu Mould cracked during heat treatment due to rough tool marks and bad protection condition
