Stamping die meet the job requirements 1, wear-resistant plastic modified blank in the mold cavity, the flow and sliding along the cavity surface, the cavity surface with a dramatic friction between billet, resulting in mould failure due to wear and tear.
So the wear resistance of materials is one of the most basic, the most important performance of mould.
2, strong toughness die working conditions are very bad, some often bear greater impact load, which can lead to brittle fracture.
Suddenly brittle fracture at work to prevent mold parts, mold with high strength and toughness.
Mould toughness mainly depends on the material state of carbon content, grain size and organization.
3, die working process, the fatigue fracture performance under cyclic stress of long-term effects, often leads to fatigue fracture.
Its form has little energy repeated impact fatigue fracture and tensile fatigue fracture contact fatigue fracture and fatigue fracture.
Fatigue fracture properties of mold mainly depends on the strength, toughness, hardness, and the content of inclusions in the material.
4, high temperature performance when the mould working temperature is higher, can make the hardness and strength, cause mould early wear or produce plastic deformation and failure.
Therefore, die material should have high tempering stability, resistance to ensure that the mold in the working temperature, has high hardness and strength.
Stamping die satisfies the requirement of process performance of mould manufacturing is typically after forging, machining, heat treatment, and a few procedure.
To ensure the manufacturing quality of mould, reduce production cost, the material should be with good malleability, cutting processability.
1, malleability has lower hot forging deformation resistance, good plasticity, forging temperature range wide, cold forging crack crack and precipitation carbide network tend to be low.
2 manufacturability, annealing of spheroidizing annealing temperature range wide, annealing hardness is low, and the fluctuation range is small, spheroidization rate is high.
3, large cutting machining cutting dosage, low dissipation of cutting tool and the processing surface roughness is low.
Stamping die mold satisfies the requirement of economy selected merchants, economy this principle must be considered, as much as possible to lower the manufacturing cost.
Therefore, stamping factory is your first choice of stamping die manufacturers, mold high precision, high cost performance, up to return the mould cost.
