Machine & Energy — Machine Specific Energy
Machine Specific Energy for injection molding operations.
Specific energy is the molding plant's fuel gauge: fixed-pump hydraulics run 0.6–0.9 kWh/kg, all-electrics 0.25–0.35. The kWh/kg gap times annual throughput is the machine-replacement business case in one line.
Formula
Note: Starting-point process values — the resin grade's datasheet and an in-mold study govern. Verify with a gate-seal study and a cooling-time ladder on the actual tool.

About Machine & Energy — Machine Specific Energy
Machine & Energy — Machine Specific Energy computes the governing relationship SE = kWh ÷ kg vs class benchmarks (~0.7 / 0.45 / 0.3) live as you type. Specific energy is the molding plant's fuel gauge: fixed-pump hydraulics run 0.6–0.9 kWh/kg, all-electrics 0.25–0.35. The kWh/kg gap times annual throughput is the machine-replacement business case in one line. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Machine & Energy — Machine Specific Energy
- 1Enter your values — Measured energy, Resin processed in the period, Machine (1 hydraulic · 2 servo-hydraulic · 3 all-electric) (sensible defaults are pre-filled).
- 2Read the live results: Specific energy.
- 3Check the "with your numbers" line to see SE = kWh ÷ kg vs class benchmarks (~0.7 / 0.45 / 0.3) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Machine & Energy — Machine Specific Energy?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
