Plastics calculators.

Quick, practical estimates to plan a part — volume and weight, tooling break-even, throughput, and mold shrinkage. They're rough by design; when you're ready for real numbers, we'll quote it.

Part volume & weight

Estimate solid-part volume and mass by material — and total resin for a run.

Tooling break-even

Compare a tooled process (molding) against no-tooling fabrication to see which wins at your volume.

Rough comparison from your inputs — not a quote.

Cycle & throughput

Estimate output and run time from cycle, cavitation, and efficiency.

Mold shrinkage

Size a cavity from the part dimension and material shrink rate.

Added for shrink

Cavity = part ÷ (1 − shrink). Typical values; actual varies by grade, geometry, and process.
