Advantages
Superior Dimensional Accuracy
Produces near-net-shape components with tight tolerances (±0.1-0.5mm)
Minimizes secondary machining requirements
Enhanced Material Strength & Durability
Refines grain structure through controlled deformation
Eliminates internal voids/porosity (superior to casting)
Achieves 15-30% higher fatigue resistance vs. machined parts
Optimal Material Utilization
Achieves 90-95% material yield (vs. 40-60% in machining)
Reduces raw material waste and costs
High Production Efficiency
Enables rapid mass production (up to 1,200 parts/hour)
Consistent output quality across production runs
Case Material:Our main case material is H13(SKD61) HRC46-48
