ENGINEERED SOLUTIONS
Powder solutions built around your part and process
Tongcheng supports material selection, filling behavior, sintering shrinkage, hardness, wear resistance and production consistency through alloy and particle-size engineering.
Enter the solution centerParticle-size distribution is unsuitable
Flow, filling and the sintering window are difficult to balance
Incorrect material choice
Hardness, toughness, corrosion resistance and cost pull in different directions
Stable in trials, variable in series production
Improve consistency through powder production, particle-size control and batch management
Standard grades do not meet the requirement
Develop an alloy formulation and particle-size plan around the target properties
