1. Market Background

In Poland’s precision casting and non-ferrous processing industries, medium-batch melting of aluminum and copper alloys is very common. If the crucible furnace capacity is too small, frequent charging and melting are required, reducing efficiency. If it is too large, energy is wasted. Finding a balance in the 300–500 kg range is a key concern when selecting a crucible resistance furnace.

2. Customer & Application Scenario

The customer is a precision casting shop producing small and medium cast blanks for local machinery manufacturers. Their old crucible furnace had limited capacity and relied on operator experience for temperature control, resulting in unstable melt quality. As orders increased, they wanted a 500 kg crucible resistance furnace to boost per-heat output and achieve more stable temperature and holding performance.

3. Our Solution (Product & Specifications)

Wuxi Wondery Industry Equipment supplied a 500 kg crucible resistance furnace with:

• Crucible capacity: 500 kg

• Heating: electric resistance

• Control: multi-point temperature measurement and intelligent controller, supporting heating curves and holding time settings

This crucible resistance furnace has a compact footprint but enough melt per heat to support multiple mould pours within one shift. Multi-point temperature measurement improves furnace temperature uniformity, helping to control alloy chemistry and melt cleanliness.

4. Customer Feedback

After a period of operation, the customer reported that the 500 kg crucible resistance furnace fits their order profile very well. The melt volume per heat matches mould cycle times, reducing frequent charging and waiting. With better temperature stability, mechanical properties of castings became more consistent and batch-to-batch variation decreased.
The customer also noted that, compared with the old furnace, the Wuxi Wondery crucible resistance furnace offers better insulation and energy utilization, reducing energy consumption per unit product and improving shop environment, which helps with environmental compliance.

5. Conclusion

For precision casting shops in Poland and other European countries, a well-designed 500 kg crucible resistance furnacecan balance capacity, quality stability and operating cost. The solution from Wuxi Wondery Industry Equipment is ideal for plants upgrading from small, outdated furnaces and focusing on higher efficiency in medium-batch alloy melting.
