📊 Stop Arguing About Capacity in Meetings. Calculate It from Speed, Micron, Roll Length, Changeover and Efficiency — in Metric Tonnes.

📖 12-min read · Capacity · PPC + Plant Heads · Live calculator

Converting capacity is not brochure speed × hours. It is what remains after uptime, changeovers (driven by roll length and job changes), quality loss and speed efficiency — converted into weight using width, micron and density. This article shows the method and gives you a working calculator you can host or use offline.

📌 Method in One Block
  • Available minutes = days × shifts × hours × 60 × overall efficiency
  • Overall efficiency from: Uptime × (1 − changeover loss) × (1 − quality loss) × speed efficiency
  • Changeover loss from: roll length + changeover time + machine speed
  • MT from: metres × width × thickness × density
  • Bottleneck capacity = lowest of Print / Lam / Slit / Pouch MT
Capacity calculation method

Live Calculator

Open the calculator below (same folder for hosting). Enter your machine counts, speeds, microns, roll length and loss factors. It returns monthly capacity in MT and highlights the bottleneck process.

💡 Use in interviews and reviews: “I don’t quote brochure speed. I calculate MT after real changeover and efficiency losses — and I know which process is the bottleneck.”

📊 मीटिंग में क्षमता पर बहस बंद करें। स्पीड, माइक्रोन, रोल लेंथ, चेंजओवर और एफिशिएंसी से MT में निकालें।

📌 विधि

उपलब्ध मिनट × स्पीड → मीटर → माइक्रोन + घनत्व से MT। बॉटलनेक = सबसे कम प्रोसेस।

💡 इंटरव्यू में: “मैं ब्रॉशर स्पीड नहीं बताता। असली चेंजओवर और एफिशिएंसी लॉस के बाद MT निकालता हूँ।”
