Understanding Energy Consumption in Extrusion Blow Molding
Energy consumption represents one of the most significant operational costs in extrusion blow molding operations, typically accounting for 30-40 percent of total production expenses in traditional hydraulic machines. As energy prices continue rising globally and environmental regulations become increasingly stringent, manufacturers are seeking low energy consumption extrusion blow molding machine (EBM) solutions that reduce operational costs while maintaining or improving production efficiency. Apollo Machinery Co., Ltd., with over 20 years of experience in plastic machinery manufacturing, offers comprehensive low-energy solutions through fully electric and servo-hybrid technologies that deliver substantial energy savings compared to conventional hydraulic systems.
The energy consumption in extrusion blow molding machines primarily occurs through several key systems: plastic extrusion and heating (45-55 percent of total energy), hydraulic system operation (25-35 percent), mold clamping (8-12 percent), and blow molding air compression (5-10 percent). Traditional hydraulic extrusion blow molding machines waste significant energy through constant hydraulic pump operation regardless of actual demand, hydraulic fluid heating, oil leaks, and inefficient motor operation during low-load periods. Apollo low-energy EBM machines address these inefficiencies through innovative drive technologies and advanced control systems that dramatically reduce energy consumption across all operational modes.
Environmental considerations and sustainability initiatives have become critical factors in modern plastic manufacturing. Companies worldwide face increasing pressure to reduce carbon footprints, lower energy consumption, and demonstrate environmental responsibility.

Apollo Fully Electric EBM Machine Technology
Apollo fully electric extrusion blow molding machines represent the cutting edge of energy-efficient plastic manufacturing technology. These machines eliminate hydraulic systems entirely, using servo motors to drive all major functions including plastic extrusion, mold clamping, blow molding, and material handling. The fully electric design achieves energy savings of 40-60 percent compared to traditional hydraulic machines while simultaneously providing superior precision, reduced maintenance requirements, and cleaner operation without hydraulic oil contamination risks.
The core energy-saving principle in Apollo fully electric EBM machines stems from servo motor technology that only consumes energy when actually performing work. Unlike hydraulic pumps that run continuously regardless of demand, servo motors deliver precise amounts of energy exactly when needed and consume virtually no power during idle periods. Additionally, servo motors achieve efficiency ratings of 85-90 percent compared to hydraulic systems at only 40-60 percent efficiency, with energy losses occurring through hydraulic pump inefficiencies, oil pipe leaks, fluid friction, and heat generation. This fundamental efficiency advantage translates directly into substantial energy savings across all production operations.
