Product Description
Nano-level Edge Passivation Tungsten Steel Cutter Die For Clean Cutting Of Copper And Aluminum Foil
Nano-level edge passivation (R0.03mm) breaks through the bottlenecks of sticking and chipping of traditional SKD11 molds, achieving ultimate clean cutting with burr height ≤3μm in 0.006mm copper and aluminum foil cutting.
Introduction
During lithium battery processing, the positive and negative ears of the battery require precise cutting. Our tungsten steel cutter die, made of hard alloy material, delivers superior performance for these applications.
Pioneer negative ear upper cutter: 40*15-12*13-10*2-R6*8-C0.5
Pioneer negative ear lower cutter: 49*42-2- φ3.4-φ6*25-2-φ4*15*5*2-R6
