Notes on process selection, tolerance limits and cost structure for powder metallurgy and precision metal parts.
Powder Metallurgy, Machining, Die Casting or Stamping: Where Each Process Fits
The same part can differ several-fold in cost and precision depending on whether it is sintered, machined, die cast or stamped. Sorting out where each process fits saves more time than repeat quoting.
Read moreWhat Sintered Density Really Means, Starting from 6.6 g/cm³
'Density not below 6.6 g/cm³' is not a decorative note on a drawing — it sets strength, hardness and wear resistance. Understanding how density, porosity and mechanical properties relate is the first step to reading a sintered part correctly.
Read moreHow Tight Can a Sintered Part Be? Separating Die-Held from Machined Tolerance
A quoted ±0.01 mm means very different things depending on whether the dimension comes from the die or from a later sizing or grinding step. Separating the two avoids most incoming-inspection disputes.
2026.08.28From Drawing to Production: How a Custom Sintered Part Gets Made
Turning a drawing into a repeatable production part means clearing feasibility review, tooling design, trial compaction, sintering parameter setting and first-article approval. Here is what is confirmed at each stage.
