Blow Molding & Hollow Plastic Products calculator

Trim Recovery Value Calculator

Trim recovery value helps decide whether flash and trim should be ground, reused, sold, or scrapped. Materials managers use it to quantify recovery from HDPE, PP, PET, and other blow molding trim while accounting for contamination, color, labor, grinder time, and customer regrind limits.

What this calculator does

  • Estimate recovered value from blow molding trim, flash, tails, and regrind using recovered material weight, value per unit, capture share, and fixed recovery costs.
  • a blow molding operation needs to value recoverable trim, flash, tail, or neck scrap from a run or shift
  • Returns the value associated with captured trim and flash recovery using the entered recovery basis.

Formula used

  • Gross captured trim value = recoverable trim and flash weight × recovered resin value × recovery capture share
  • Net trim recovery value = gross captured trim value + fixed grinding and handling cost

Inputs explained

  • Trim Recovery Value quantity: undefined
  • Trim Recovery Value rate: undefined
  • Trim Recovery Value capture factor: undefined
  • Trim Recovery Value fixed cost: undefined

How to use the result

  • Use it for regrind economics, scrap reviews, grinder justification, and material recovery reporting.
  • It does not prove regrind is acceptable for the product; verify contamination, color, melt history, and customer limits.

Common questions

  • What information do I need for trim recovery value? Enter recoverable trim weight, value per lb or kg, recovery capture share, and fixed grinding or handling 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 prove regrind is acceptable for the product; verify contamination, color, melt history, and customer limits.
  • How can I use the result? Use it to decide whether to grind trim, segregate colors, sell scrap, or invest in better recovery equipment.
