5 Key Metrics Every Mold Shop Should Track

2026-05-31

Tracking the right KPIs helps mold shops identify inefficiencies and improve profitability.

1. First-Shot Acceptance Rate
- Target: 85%+
- What it measures: Percentage of molds that produce acceptable parts on first tryout
- Why it matters: High rate = good design and machining accuracy; each rework costs 500-3000

2. Machine Utilization Rate
- Target: 75-85% for well-run shops
- What it measures: Actual cutting time vs available machine time
- Why it matters: A shop with 10 CNCs at 65% utilization effectively has 6.5 machines working

3. On-Time Delivery Rate
- Target: 95%+
- What it measures: Molds delivered on or before promised date
- Why it matters: Late delivery costs penalties and damages reputation

4. Rework Cost as Percentage of Job Value
- Target: Under 3%
- What it measures: Cost to fix errors vs total job value
- Why it matters: Each percentage point over 3% directly reduces margin

5. Average Quote-to-Order Conversion
- Target: Industry average is 30-40%
- What it measures: Percentage of quoted jobs won
- Why it matters: Low conversion may mean pricing is wrong or sales process needs work
