The company’s low energy consumption extrusion machines incorporate advanced technologies such as servo motors, heat recovery systems, and optimized screw designs to achieve significant energy savings without compromising production efficiency or product quality.
Energy Consumption in Plastic Pipe Extrusion
Energy consumption is a major concern in the plastic pipe industry, as it accounts for a significant portion of the total production cost. The main energy-consuming components of a plastic pipe extrusion line include:
Extruder Motor
The extruder motor is the largest energy consumer in an extrusion line, accounting for **60-70%** of total energy consumption. The motor drives the screw, which melts and transports the plastic material through the extruder barrel.
Heating System
The heating system is used to melt the plastic material and maintain the required temperature in the extruder barrel. It typically consists of electric heaters or oil heaters, accounting for **20-25%** of total energy consumption.
Vacuum System
The vacuum system is used to remove air and moisture from the plastic material during the extrusion process, ensuring the quality of the final product. It accounts for **5-10%** of total energy consumption.
Haul-off Unit
The haul-off unit pulls the extruded pipe through the cooling system and cutting machine. It accounts for **3-5%** of total energy consumption.
Cutting Machine
The cutting machine cuts the continuous pipe into specified lengths. It accounts for **2-3%** of total energy consumption.
