Explore Tongcheng’s engineering approach to material and manufacturing challenges involving scissors, nail clippers, thin-walled MIM parts, sintering shrinkage, powder flow, batch consistency, watch components, and valve and pump parts.
This column is constructed based on common parts requirements in the industry and is used to demonstrate the material and process support that Tongcheng can provide. It does not point to specific customers or unconfirmed delivery results.
From part issues to materials, processes and verification paths
Typical parts and production challenges illustrate how Tongcheng develops projects from material and particle-size selection through forming, sintering and validation.
Enter project from part target
Application cases should not just list product names. Tongcheng starts from part goals such as hardness, wear resistance, corrosion resistance, size, surface and series production stability, and then determines the material, particle size and manufacturing route.
Design solution from problem chain
Put alloy formulation, powder particle size, feedstock or pressing, debinding, sintering, heat treatment and surface treatment in the same problem chain to reduce the repetition caused by adjusting only a single parameter.
From verification project to procurement
Each typical plan lists the recommended information to be submitted, verification projects and procurement communication points, making it easier for customers to directly convert similar needs into evaluable inquiries.
The engineering team can further evaluate based on actual grade, particle size, process, target results and procurement plan.
Typical parts and manufacturing problem resolution paths
Use engineering scenarios to present problems, material directions, process troubleshooting and verification projects to help similar needs quickly enter into communication.
