As global carbon emissions increasingly impact the environment and climate, and with governments around the world promoting environmental policies and ESG (Environmental, Social, and Governance) trends, energy saving and carbon reduction have become pressing issues across all industries. With rising electricity and carbon tax costs, companies are under pressure to implement effective strategies to cut emissions. In response to this trend, Victor Taichung has actively promoted its series of all-electric machines, while also offering concrete solutions in two major areas: plastic material conservation and energy efficiency.
Reducing Plastic Usage
In reducing plastic usage, Victor Taichung is actively exploring how to increase the proportion of recycled plastics used, without compromising production yield. To achieve this, Victor Taichung has integrated its existing full-electric adaptive functionality, barrel design knowledge, and in-mold sensing technologies to implement high-efficiency quality inspections and developed the “Recycled Material UP” solution. As illustrated in Figure 1, this solution significantly improves the use of recycled materials, reducing the consumption of virgin plastics and lowering carbon footprint.

Another method to reduce plastic usage is thin-wall molding. Traditionally, thin-wall molding is considered challenging due to two main reasons:
1.The thinner the wall, the greater the resistance the plastic melt faces while flowing through the mold, requiring higher molding speed and precision.
2.The time window for molding becomes narrower, and any delay or inaccuracy may cause product defects such as short shots, warping, or unevenness.
To tackle these challenges, Victor Taichung launched the VαⅢ HR Series in 2024. This series features a low-inertia mechanical structure combined with dual-motor synchronous drive technology, delivering acceleration performance over 3.5G. Testing has confirmed its ability to meet the requirements of thin-wall molding.

Take a 0.2mm-thick PC product as an example: the VαⅢ HR Series successfully reduced the injection time from the traditional 0.066 seconds to just 0.043 seconds—a time savings of approximately 65%. This also effectively reduced occurrences of short shots at the end of the weld line, enhancing both molding efficiency and product quality.

Efficient Energy Utilization
When switching from conventional hydraulic machines to all-electric ones, the greatest energy loss usually comes from barrel heating. Traditional methods use insulation materials such as fiberglass or aerogel to retain heat, which are effective but face challenges with high-viscosity or high-crystallinity plastics. During plasticizing, more screw shear is needed, which can lead to insufficient cooling and overheating. Additionally, when using heat-sensitive materials, residual heat during downtime may degrade the melt, causing defects like black specks.
To address this, Victor Taichung developed an energy-saving thermal shield that combines both insulation and cooling functions. These shields not only minimize heat loss during heating but also manage heat dissipation in high-temperature environments, preventing melt degradation and ensuring product quality. In the future, Victor Taichung plans to further integrate software and hardware to improve temperature control precision and maximize energy efficiency.
Reducing Ineffective Holding Pressure
In traditional injection molding, the holding pressure stage can consume a large amount of energy, especially when pressure is set too high or held for too long, leading to unnecessary energy waste. To address this issue, Victor Taichung introduced in-mold sensing components that monitor the injection process through waveform comparison and verify holding pressure effectiveness. This allows the system to eliminate ineffective pressure and achieve energy savings.
In practical applications, by shortening the holding time, Victor Taichung has reduced the total energy consumption of injection molding machines by 6%. This improvement not only cuts down on energy usage but also enhances product quality, as more precise holding pressure settings help reduce internal stress and minimize the risk of deformation.

Conclusion
Victor Taichung’s energy-saving and carbon reduction solutions for injection molding machines span multiple areas of technical innovation. First, the use of recycled materials and thin-wall molding technologies helps reduce plastic consumption and achieve environmental goals. Second, replacing hydraulic systems with all-electric machines and applying advanced thermal insulation and cooling methods improves energy efficiency. Lastly, in-mold sensing technology enables data-driven control to eliminate unnecessary holding pressure, further lowering energy consumption.
These technologies not only help reduce energy use but also improve production efficiency and product quality—bringing significant benefits to sustainable development. Victor Taichung will continue to explore and integrate more feasible technologies to advance energy-saving efforts in the injection molding industry and contribute to global environmental protection.
