Energy-saving injection molding machine becomes the mainstream of product innovation
In order to enhance energy efficiency in injection molding machines, commonly referred to as "electric tigers," major manufacturers have been actively developing and implementing new energy-saving technologies. As a result, energy-efficient injection molding machines are now becoming the dominant trend in product innovation within the industry.
Driven by continuous research and development efforts, a wide range of new products has emerged in the injection molding machine market. Among these, the all-electric injection molding machine stands out as a key innovation. It operates at low speeds during pressure holding, cooling, and idle phases, significantly reducing energy consumption and noise levels. However, one drawback is its relatively shorter service life compared to traditional models.
Another notable advancement is the electric-hydraulic injection molding machine, which combines the benefits of hydraulic pressure with electric drive systems. This hybrid approach challenges the traditional hydraulic injection molding market by integrating the high performance and energy efficiency of fully electric machines. It improves the efficiency of the power drive system, reduces energy loss, and accelerates the adoption of energy-saving technologies in hydraulic injection molding machines.
In addition to technological improvements, innovations in the core principles of energy-saving injection molding also play a crucial role in reducing energy use. For instance, Ningbo Haihang Plastic Machinery Manufacturing Co., Ltd. has applied the principle of energy-saving injection molding for large parts, using low-pressure and high-speed external heat flow. They have developed an ultra-large 50-kg energy-saving injection molding machine. The hydraulic power system only requires 37 kW of power, which is just 1/7 to 1/6 of the power required by conventional horizontal injection molding machines of the same specification. The total load power of the entire machine is only 192 kW, showcasing remarkable energy efficiency.
These developments reflect the growing emphasis on sustainability and efficiency in the injection molding industry, as manufacturers strive to meet both environmental and economic demands.
