For scissors, shearing mechanisms and precision cutting-edge components, develop a project plan around 440C, fine-powder filling, sintered density, heat treatment, edge quality and surface finish.
This page is a typical project plan and does not correspond to a specific customer name or unconfirmed delivery results.
Divide similar projects into four executable links
Demonstrate how scissors and shears can be used to develop projects around 440C, thin edge filling, sinter density, heat treatment and edge results.
Project Goals: Hardness, Wear Resistance and Edge Retention
Shear parts must not only obtain sufficient hardness and wear resistance, but also take into account toughness, assembly size, edge processing and corrosion resistance requirements in the use environment.
Common difficulties: thin edge filling and sintering deformation
Variations in cutting edges, shaft holes, stiffeners, and thickness will amplify differences in feedstock fill, local density, debinding support, and sintering shrinkage, ultimately affecting cutting edge straightness and fit.
Tongcheng solution: 440C Powder and particle size synergy
Taking 440C as the priority material direction, combined with customer feedstock, mold, sintering and heat treatment routes, the complete particle size distribution, filling performance, sintering density and hardness window are evaluated.
Validation focus: part results rather than single powder parameters
It is recommended to compare critical dimensions, warpage, sintered density, heat treatment hardness, edge processing, wear and corrosion testing, and record powder batches and heats.
The engineering team can further evaluate based on actual grade, particle size, process, target results and procurement plan.
