1) Regional Demand & Process Challenges

Bolivia’s mining and construction machinery sectors require high-strength, high-toughness structural and critical components. Many such parts need complex processes at 1100–1250°C, including normalizing, solution treatment and high-temperature quenching. This places demanding requirements on the maximum temperature, power and chamber size of any heat treatment furnace used.

2) Customer Application Scenario & Constraints

The customer is a machining plant producing critical parts for mining and construction equipment. Parts are large, and materials are mostly medium- to high-strength alloy steels. Their existing heat treatment equipment had a small chamber and insufficient maximum temperature, forcing them to outsource many high-temperature processes. This resulted in long lead times and high costs. The customer wanted an in-house high-temperature heat treatment furnace to bring key processes under their own control.

3) Furnace Configuration & Key Specifications

Wuxi Wondery Industry Equipment designed and supplied a heat treatment furnace with a 2000×1500×1000 mm chamber, 180 kW power and a maximum temperature of 1250°C:

• Chamber size: 2000×1500×1000 mm, suitable for most critical construction machinery parts;

• Heating power: 180 kW with multiple heating zones, ensuring heating rate and temperature uniformity;

• Maximum temperature: 1250°C, covering normalizing, solution treatment and some high-temperature quenching.

This heat treatment furnace uses high-temperature-resistant linings and insulation designed for stable operation and reduced thermal losses. Multi-step process curves can be set for different steels and process routes.

4) Operating Results & Customer Feedback

After commissioning, the customer brought high-temperature normalizing and some solution treatments back in-house, significantly shortening delivery times. The 2000×1500×1000 mm chamber can hold most critical parts without splitting or multi-furnace assemblies.
The customer reported that high-temperature cycles run in the Wuxi Wondery heat treatment furnace show better distortion control and more uniform microstructures, reducing machining difficulty in subsequent operations. The 180 kW power rating offers a good balance between capacity and energy consumption, leaving room for additional shifts in the future.

5) Project Value Summary

For Bolivia and other markets focused on mining and construction machinery, a high-temperature heat treatment furnace with a 1250°C limit and appropriate chamber size can greatly enhance local control over critical part heat treatment. The high-temperature furnace solution from Wuxi Wondery Industry Equipment provides a solid foundation for customers to extend into more advanced processes in the future.
