  "description": "Powder coating cost is driven by surface area (which determines powder consumption via transfer efficiency), labor for hanging/masking/unhanging, and the fixed oven/booth operating cost amortized across a batch run. Powder transfer efficiency for electrostatic spray typically runs 60-80% for simple shapes and drops to 40-60% for complex geometry with recesses (Faraday cage effect), meaning a meaningful share of sprayed powder never lands on the part — reclaim systems recover some of this overspray but not all. This calculator estimates powder used from part surface area, coating thickness, and transfer efficiency, then adds labor and a per-batch oven/booth overhead allocation divided across batch size. Use it to quote finishing as an add-on service or to decide whether in-house powder coating beats outsourcing to a job coater at their per-part or per-pound pricing.",
  "formula": "Powder Weight (g) = Surface Area (in²) × Thickness (mil) × Density Factor ÷ Transfer Efficiency. Cost = Powder Cost + Labor + (Oven/Booth Overhead ÷ Batch Size).",

    {
      "q": "What transfer efficiency should I assume?",
      "a": "Simple flat or box-shaped parts with good electrostatic ground typically hit 70-80% efficiency. Parts with deep recesses, tubing, or complex fixtures where the Faraday cage effect blocks powder from reaching inner corners often drop to 40-55%, even with post-cure touch-up spraying."
    },
    {
      "q": "Does powder reclaim change this cost?",
      "a": "Reclaim systems recover 40-70% of oversprayed powder for reuse, effectively raising your usable transfer efficiency. If your booth has a working reclaim system, you can input a higher effective transfer efficiency to reflect that recovered powder, though reclaimed powder often gets blended at a lower ratio to maintain finish quality."
    },
    {
      "q": "How does this compare to outsourcing to a job coater?",
      "a": "Job coaters typically price at $0.50-$3+ per part depending on size and complexity, or by the pound for large batches. Run this calculator for your in-house numbers and compare directly — outsourcing usually wins for low volume or occasional jobs, in-house wins once you have steady volume to keep the booth and oven utilized."
    },
    {
      "q": "What's a typical coating thickness target?",
      "a": "Most functional and architectural powder coating specs call for 2-4 mils (dry film thickness). Thinner coats (under 2 mil) risk poor coverage and corrosion protection; thicker coats (over 5 mil) waste powder and can cause orange peel or edge coverage issues."
