1. Market Background

As Tanzania’s construction and automotive repair markets expand, demand for recycled aluminum castings continues to grow. Early adopters of upgraded equipment soon realized that a single melting furnace had become a capacity bottleneck. The challenge is how to expand melting capacity smoothly without significantly increasing management complexity.

2. Customer & Application Scenario

This customer already operated a 350 kg resistance crucible melting furnace from Wuxi Wondery Industry Equipment. After stable operation of the first furnace, orders increased and the single unit had to run near full load for long periods, leaving little time for maintenance. The customer decided to purchase a second 350 kg resistance crucible melting furnace and run two furnaces in a coordinated mode while maintaining proper maintenance intervals.

3. Our Solution (Product & Specifications)

Wuxi Wondery Industry Equipment supplied a second 350 kg resistance crucible melting furnace with the same capacity, heating method and control system as the first:

• Capacity: 350 kg

• Heating: electric resistance

• Control: the same controller model and temperature control logic

The two resistance crucible melting furnaces are assigned by alloy grade or product type: one handles main alloys, and the other serves small batches or trial production, reducing frequent alloy changes on a single furnace.

4. Customer Feedback

With two furnaces running in coordination, the customer’s maximum daily pouring capacity increased significantly. During peak periods, both resistance crucible melting furnaces can be used; in off-peak seasons, one furnace can be shut down to save energy. Because the two furnaces share the same structure and operating interface, operators required no additional training and spare parts inventory could be unified.
The customer noted that casting quality did not deteriorate as capacity expanded. Stable temperature control from the resistance crucible melting furnaces ensured molten aluminum quality, giving them greater confidence when opening new markets.

5. Conclusion

For Tanzanian recycled aluminum plants expanding capacity, adding multiple units of the same resistance crucible melting furnace is a manageable and low-risk approach. The 350 kg resistance crucible melting furnace combination from Wuxi Wondery Industry Equipment maintains process continuity and provides a proven template for further expansion of melting units.
