How do I calculate powder fill weight for a PM part?

Fill weight equals the finished part volume times target green density, adjusted for machining stock and expected powder loss, plus the admixed lubricant. The Powder Fill Weight calculator takes part volume, target green density, and lubricant percentage to return grams per part and fill depth given your apparent density. That figure sets the die fill and feeds directly into Compaction Tonnage and Cost Per Sintered Part.

What compaction tonnage does my part require?

Tonnage is the target compaction pressure times the part's projected area normal to pressing. The Compaction Tonnage calculator multiplies projected area by the pressure needed for your target green density, typically 400 to 800 MPa for ferrous PM, and returns required press tons with a safety factor. Comparing that to your press rating tells you whether a part fits the press or needs a larger machine, which changes hourly rate and throughput.

How much shrinkage should I allow between green and sintered dimensions?

Sintering shrinkage depends on powder type, green density, and sinter temperature, often 0 to 2 percent linear for ferrous and higher for some alloys. The Shrinkage Allowance calculator applies your measured or specified shrink factor to green dimensions so the die is oversized correctly to hit final size. Pairing it with Density Variation helps predict non-uniform shrink across sections that may need a Sizing Press repress.

How do I size sinter furnace capacity for a production run?

Furnace capacity is set by belt width and speed or tray load, part footprint, and the time at temperature. The Sinter Furnace Capacity calculator returns parts per hour from belt loading and cycle time, and Debind Time and Furnace Energy Cost add the delube zone and the energy per part. Together they tell you how many furnace hours a lot needs and whether sintering, not pressing, is your bottleneck for Batch Throughput.

How is cost per sintered part calculated?

Start with powder cost from Powder Fill Weight and Powder Loss Rate, net of Scrap Reclaim Value, then add press time via Compaction Tonnage and throughput, Furnace Energy Cost, Labor Per Batch, and Inspection Cost. The Cost Per Sintered Part calculator sums these and Tooling Amortization spreads die cost over program volume. This shows how higher green density or better part yield lowers the per-piece number before Quote Margin is applied.

How does powder loss rate affect material cost?

Powder loss covers spillage, fines, rejected green parts, and admix that never becomes a good part, usually a few percent of feed. The Powder Loss Rate calculator converts that percentage into extra powder purchased per thousand good parts, and Scrap Reclaim Value credits back recoverable material. Since powder is the dominant material cost in PM, trimming loss from 5 to 2 percent can move cost per part more than most press-speed gains.

Powder Metallurgy & Sintered Parts calculators

This category covers the math of press-and-sinter powder metallurgy, from powder fill and compaction force through green density, sintering shrinkage, and finished part cost. It is built for PM process engineers, tooling designers, and estimators who need to size presses, furnaces, and powder consumption before committing a part to production.

Best calculators in this category

Powder Fill Weight: Powder Fill Weight is the mass of metal powder that must drop into the die cavity to press a single green compact at the target dimensions.
Compaction Press Throughput: This calculator turns a shift's press output into an effective parts-per-hour rate for a powder metallurgy compaction line.
Green Density: Green density is the as-pressed density of a powder metallurgy compact before it enters the sintering furnace, and it is one of the most watched numbers in the process.
Sinter Furnace Capacity: Sinter furnace capacity tells a powder metallurgy plant how many good, dimensionally sound parts a belt or batch furnace can actually deliver over a planning period, not just how many it can theoretically hold.
Shrinkage Allowance: Shrinkage allowance is the dimensional gap a powder metallurgy part loses (or, for some alloys, gains) as it densifies during sintering, and it is the number that decides how big the compaction die and core rods must be cut.
Powder Loss Rate: Powder loss rate measures how much of the metal powder you charge into a PM operation ends up as spillage, fines, oversized reclaim, or scrapped green parts rather than usable product.
Press Tooling Run Output: Tooling amortization in powder metallurgy comes down to how many good parts a die set actually produces per hour of press time, because that throughput is what you divide the tool's build cost across to get a per-part tooling charge.
Furnace Energy Cost: Furnace Energy Cost is the total electricity or gas spend attributed to running a sintering furnace for a given batch of powder-metal parts, split into a per-part figure.
Part Yield: Part Yield in powder metallurgy tracks the share of pressed-and-sintered components that fail inspection, cracks, laminations, density gradients, dimensional drift after sizing, or blister defects from poor dewaxing.
Cost Per Sintered Part: Cost Per Sintered Part is the fully loaded cost to make one acceptable powder-metal component, blending variable conversion cost, a yield adjustment for scrap, and fixed tooling and setup spread across the lot.
Lubricant Blending Capacity: This Lubricant Addition calculator translates a shift's pressing output into an hourly throughput rate, then discounts it by a blend-efficiency factor that reflects how well the admixed lubricant is performing during compaction and ejection.
Debind Time: Debind time is the furnace or oven time needed to remove the binder and lubricant from green powder metal compacts before sintering.

The producer price index for steel mill products stands at 361.439 (BLS, Jun 2026), up 16.9% from a year earlier. Quotes priced off last quarter's material cost miss this move.
U.S. iron and steel imports ran $2.2B in Jun 2026 (Census International Trade). The U.S. ran a trade deficit of $0.4B in the category that month. Import volumes are the pressure gauge behind tariff and reshoring decisions.
