On April 8th, the procurement team from a major US heavy machinery brand visited the Duma Machinery Crusher wear-resistant parts Casting Base to conduct a full-process factory inspection of core wear parts, including jaw plates and crushing walls, which they had already ordered. The clients thoroughly examined all 12 production stages, from raw material testing to finished product packaging, and particularly praised the smart casting production line powered by photovoltaic energy.
Photovoltaic Roof Powers Green Casting
During the inspection, the 1800KW photovoltaic project covering 20,000 square meters of the factory became a focal point. This project generates 6,000 kWh of electricity daily, meeting 30% of the casting workshop's energy demand, equivalent to reducing carbon dioxide emissions by 472 tons annually. "Using solar energy directly for the high-energy-consumption casting of Crusher wear-resistant parts is a model worth promoting," said the US client's Technical Director.
Off-Peak Electricity Furnace Start-Up + Smart Melting Yield Results
The factory showcased its green production and energy-saving scheduling strategy for wear parts: electric arc furnace melting is carried out during off-peak hours at 2 a.m., combined with photovoltaic energy during the day, reducing the energy consumption per ton of casting by 18%. This "photovoltaic + off-peak electricity" dual-track approach has led to a 23% reduction in the company's overall electricity costs.
Full-Process Quality Control of Wear Parts Certified
The clients focused on inspecting key production steps for Crusher wear-resistant parts: spectral analysis ensures material hardness reaches HRC58-62, sand cleaning guarantees surface smoothness, and X-ray testing ensures internal zero defects. Randomly sampled crushing wall castings exceeded industry standards by 12% in wear-life testing.
"From the application of green energy to millimeter-level precision control, this factory has redefined the production standards for wear parts casting," said the US client's Purchasing Manager in the debriefing meeting.
