Blow Molding & Hollow Plastic Products calculator

Defect Cost Calculator

Defect cost makes quality losses visible when bottles or hollow parts are rejected for leaks, short shots, thin walls, flash, poor neck finish, contamination, weight variation, or cosmetic defects. Quality and operations teams use it to prioritize corrective action and supplier or tooling fixes.

What this calculator does

  • Estimate cost of blow molded defects from rejected bottles or containers, average defect cost, allocation share, and fixed containment or sorting costs.
  • a blow molding plant needs to quantify the cost impact of rejected containers, sorting, rework, or customer containment
  • Returns estimated cost tied to defective blow molded output and containment activity.

Formula used

  • Allocated variable defect cost = defective bottles or containers × average cost per defective container × defect cost allocation share
  • Total blow molding defect cost = allocated variable defect cost + fixed containment and sorting cost

Inputs explained

  • Defect Cost quantity: undefined
  • Defect Cost rate: undefined
  • Defect Cost capture factor: undefined
  • Defect Cost fixed cost: undefined

How to use the result

  • Use it for cost of poor quality, customer complaints, MRB reviews, mold repair justification, and corrective action prioritization.
  • It does not capture brand impact, recall exposure, or safety risk; critical defects need escalation beyond the cost estimate.

Common questions

  • What information do I need for defect cost? Enter defective container count, average cost per defect, allocation share, and fixed sorting, containment, or customer response cost.
  • Which units should I use? Use one consistent basis for the whole calculation, such as grams, pounds, kilograms, bottles, containers, mold cycles, hours, psi, or dollars. Do not mix grams and pounds or bottles and cases without converting first.
  • When is this only an estimate? It does not capture brand impact, recall exposure, or safety risk; critical defects need escalation beyond the cost estimate.
  • How can I use the result? Use it to justify tooling repair, process tuning, inspection changes, supplier claims, or added leak-test capacity.
