At EPoS Technologies SA, sustainability is at the heart of innovation. Our unique Electro-Sinter-Forging (ESF) technology offers a revolutionary alternative to traditional sintering methods, allowing for significant reductions in energy consumption and CO₂ emissions. This advanced process is designed not only to produce high-performance materials but to do so with minimal environmental impact.

Environmentally Friendly Manufacturing Process

Traditional Sintering vs. Electro-Sinter-Forging (ESF)

Conventional sintering methods require long process times and high temperatures—often exceeding 1600°C for several hours—resulting in considerable energy demands and CO₂ emissions. By contrast, our ESF process achieves similar results at room temperature with a rapid discharge time of just 30 milliseconds and an overall processing time of only six seconds per part. This substantial reduction in process time and temperature translates into a lower energy footprint and fewer emissions.

Comparative Energy and CO₂ Emission Reduction, the case of Copper-Molybdenum-Copper for Semiconductor Thermal Management

From a detailed analysis of our processes, including both traditional batch sintering and ESF, we see a marked advantage in sustainability due to the importance reduction in processing steps (5 instead of 10) and the reduced energy and materials consumption required to prepare the same parts:
• Energy Consumption: The ESF process for producing materials competing with CPC laminates uses only 5.5 kWh/kg, a dramatic improvement over the 16.65-20.65 kWh/kg required in traditional sintering processes.
• CO₂ Emissions: By switching to ESF, CO₂ emissions are reduced by 65-72% compared to conventional methods.

Advantages for Thermal Management Applications

Our CPC (Copper-Molybdenum-Copper) composites are essential for advanced thermal management and semiconductor packaging, where efficient heat dissipation is crucial. With ESF, we achieve a thermal conductivity of up to 320-330 W/mK, comparable to traditionally sintered materials but with a significantly smaller environmental footprint. This makes ESF-produced CPC composites an ideal choice for companies committed to both performance and sustainability in their supply chains.

Sustainability in Every Step

The ESF process supports a sustainable lifecycle, from production to end-of-life. With our high material yield (~80%) and minimal waste generation, we reduce resource consumption and maximize efficiency. Additionally, our products come with batch traceability, ensuring responsible end-of-life recycling and reducing the environmental burden associated with electronic waste.
