The Margin Squeeze Facing Small EU Foundries#
European electricity prices for industrial users averaged EUR 0.18 per kWh in 2025, roughly double the 2020 level. A 12-person foundry near Brescia, Italy, running a 2-tonne induction furnace saw energy climb from 18 % to 29 % of casting cost. Without granular data, management could not tell which product lines still earned a positive contribution. AskBiz broke costs into energy, scrap input, alloy additions, refractory, and labour per melt cycle, revealing that three low-volume part numbers were losing EUR 0.40 per kg.
Measuring Melt Yield Accurately#
Melt yield is the ratio of good castings to charged metal. Industry benchmarks for small induction shops sit between 55 % and 70 %. A Czech foundry logging each heat in AskBiz found its actual yield was 58 %, largely because of oversized risers on a legacy pattern. Redesigning the gating system lifted yield to 65 %, saving EUR 0.32 per kg of finished casting at a scrap price of EUR 0.38 per kg.
Energy Benchmarking Per Tonne of Liquid Metal#
A well-run induction furnace melts steel at roughly 550 to 650 kWh per tonne of liquid metal. AskBiz logs kWh meter readings per heat alongside charge weight so the foundry can track drift. The Brescia shop discovered that Monday morning heats consumed 12 % more energy because the furnace lining had cooled over the weekend. Scheduling a low-value maintenance melt on Monday mornings cut average consumption from 640 kWh to 605 kWh per tonne, saving approximately EUR 4,500 per year.

Alloy Surcharge and Scrap Price Pass-Through#
Nickel, chromium, and molybdenum prices swing weekly. AskBiz links alloy cost tables to each product recipe so quotes update automatically. A Spanish stainless-steel foundry using grade CF8M avoided a EUR 7,200 loss on a single order when nickel jumped EUR 1,100 per tonne between quotation and pour date, because the system flagged the margin erosion before production started.
Quoting With Confidence#
Small foundries often quote from memory or outdated spreadsheets. AskBiz generates a cost build-up in seconds: metal cost per kg at current scrap rate, energy per kg at the latest tariff, labour minutes from historical cycle times, and a configurable margin. A German foundry reported that quote turnaround fell from two days to thirty minutes, winning three new customers in a single quarter.
People also ask
What is a good melt yield for a small steel foundry?
Small induction foundries typically achieve 55 % to 70 % melt yield depending on casting complexity and gating design. AskBiz tracks yield per pattern so foundries can target improvements where losses are highest.
How much electricity does it take to melt one tonne of steel?
Induction furnaces consume roughly 550 to 650 kWh per tonne of liquid steel. AskBiz logs actual consumption per heat to identify drift and schedule maintenance before efficiency drops further.
How can small foundries pass on rising energy costs?
Transparent cost-plus quoting backed by real data is the most effective approach. AskBiz builds energy cost into every quote automatically, making surcharge conversations with customers factual rather than adversarial.
Our team combines expertise in data analytics, SME strategy, and AI tools to produce practical guides that help founders and operators make better business decisions.
Melt Smarter, Quote Faster
AskBiz gives small foundries live cost-per-tonne data so every casting ships at a known margin.
