EconPlast - Energy Efficient Plasticizing for Modern Injection Molding
Rising energy costs and sustainability targets are redefining the priorities of modern injection molding operations. Energy efficiency is no longer an option but a decisive competitive factor. EconPlast is an innovative plasticizing concept developed to dramatically reduce energy consumption during the most energy-intensive phase of injection molding: plasticizing.
By optimizing how energy is introduced, distributed, and retained during material melting and dosing, EconPlast enables injection molding machines to achieve significantly lower operating costs while simultaneously improving process stability and part quality.
Understanding Energy Consumption in Injection Molding
In injection molding, a substantial portion of total energy consumption is used to melt the plastic material and drive the rotation of the plasticizing screw during dosing. Conventional plasticizing units suffer from high energy losses caused by radiation, convection, cooling water, friction, and hydraulic inefficiencies. Much of the supplied electrical energy never reaches the polymer melt effectively.
EconPlast addresses these inefficiencies by rethinking the entire plasticizing energy balance. The result is a system where a far greater share of the supplied energy is converted directly into usable melt enthalpy, instead of being lost to the surroundings.
How EconPlast Works
EconPlast is based on an optimized plasticizing unit design that significantly reduces heat losses and friction while improving temperature control accuracy. Energy input is better synchronized with material flow and screw operation, ensuring that heat is applied precisely where and when it is needed.
Improved insulation, optimized heating zones, and enhanced cooling control of the feed zone allow EconPlast to maintain stable processing conditions with substantially less energy input. The system also minimizes unnecessary hydraulic and mechanical losses during dosing.
Key Advantages of EconPlast Technology
Substantial Energy Savings
EconPlast reduces energy consumption during heating by up to 40 percent and lowers energy losses during dosing by approximately 60 percent. These savings directly translate into lower electricity costs per produced part.
Faster Start-Up and Warm-Up
Thanks to faster and more precise temperature regulation, machines equipped with EconPlast reach stable operating conditions in a shorter time. This reduces start-up scrap and increases productive machine hours.
Improved Melt Quality and Homogeneity
Optimized heat transfer and reduced friction lead to more uniform melting and improved material homogeneity. This results in consistent part quality and enhanced process reliability, even with sensitive or demanding materials.
Lower Scrap Rates
Material-friendly processing conditions and stable plasticizing significantly reduce thermal stress on the polymer. This leads to fewer defects, less material degradation, and lower reject rates.
Extended Service Life
The highly wear-resistant design of the EconPlast plasticizing unit increases durability and reduces maintenance requirements, contributing to lower lifetime operating costs.
Optimized Cooling with Minimal Losses
EconPlast improves feed zone cooling efficiency while drastically reducing energy losses to cooling water and the surrounding environment.
Proven Economic and Environmental Impact
The energy-saving potential of EconPlast increases with higher material throughput and longer operating hours. In multi-shift operations, the annual cost savings can be substantial, making EconPlast particularly attractive for high-utilization production environments.
Beyond cost reduction, the lower energy demand leads to a significant decrease in CO₂ emissions. Depending on machine size and operating conditions, this can amount to several tons of CO₂ reduction per year, supporting sustainability goals and environmental compliance.
Outstanding EUROMAP 60.1 Efficiency Performance
Injection molding machines equipped with EconPlast achieve excellent results according to the EUROMAP 60.1 energy efficiency standard. Specific energy consumption values below 0.32 kW per kilogram of material flow rate are achievable, placing these machines in the top efficiency class.
The highest classification level, including the plus rating for low idle energy consumption, confirms EconPlast as a benchmark solution for energy-efficient injection molding technology.
Compatibility and Flexibility
EconPlast is available for injection molding machines with screw diameters of 18 mm and above and can be integrated across a wide range of machine sizes and clamping forces. This makes it suitable for applications ranging from precision technical parts to high-volume production.
Its compatibility with modern machine control systems allows seamless monitoring, evaluation, and optimization of energy consumption and process performance.
