Introduction of HTE immersion heaters in the automotive manufacturing industry: heating efficiency exceeding 98%, with simultaneous improvements in production capacity and precision

Integrated die casting has become a mainstream manufacturing process in the automotive industry. Utilizing ultra-large die casting equipment with a clamping force of ≥6,000 tons, this technology enables the one-step die casting of large aluminum alloy automotive structural components. Currently, multiple automakers—including Zeekr, and XPeng—have established in-depth collaborations with SGJL. The HTE immersion heater achieves a thermal efficiency exceeding 98%, eliminating the risk of localized overheating in molten aluminum, effectively enhancing the purity of the molten aluminum, and empowering customers to achieve dual advancements in production capacity and machining precision.

From a thermal efficiency of only 82%–89% with conventional immersion heaters to the adoption of HTE immersion heaters brings benefits to manufacturers:

Ultra-high thermal efficiency —— The heaters independently developed by SGJL boast a thermal efficiency exceeding 98%, meeting the needs of major manufacturers for rapid heating and precise temperature maintenance.

Ultra-low energy consumption —— Under production operating conditions, the molten aluminum temperature was maintained at 690 °C for 12 consecutive hours, with an electricity consumption of approximately 1,100 kWh; the average energy consumption per heater was 11.46 kW·h.

Minimal loss —— Annual aluminum melt loss is only 100–200 kg, significantly reducing raw material loss.

“In the framework of our long-term strategic partnership, SGJL will uphold the shared value principles of lean operations, energy efficiency and consumption reduction, and enduring reliability; leveraging our exceptional capabilities in technological research and development, we will continuously drive product upgrades across the industry and establish a pioneering foundation for high-end materials.”
