Did you know that an all-electric injection molding machine can mold a part with 0.1mm wall thickness in just 0.1 seconds? In the wave of automotive lightweighting, Tesla's battery module housing exemplifies a dual breakthrough in strength and insulation—thanks to all-electric injection molding technology. This is not only a technological triumph but also a reflection of the global manufacturing industry's shift toward efficiency, precision, and sustainability.
According to Grand View Research, the global market size for all-electric injection molding machines reached USD 9.8 billion in 2023 and is expected to exceed USD 22 billion by 2030. Behind this growth lie three major barriers traditional hydraulic machines struggle to overcome: high scrap rates due to poor precision, environmental risks from hydraulic oil contamination, and uncontrolled costs caused by high energy consumption. In contrast, all-electric machines offer ±0.5% injection accuracy, 60% energy savings, and zero oil pollution—making them a game-changer for manufacturers.
So, what pain points can all-electric injection molding machines truly address? What critical components can they produce? This article explores the main application fields and demonstrates how these machines drive production innovation across industries.
