The technology behind plastic injection molding machine in industries such as automotive, electronics, and consumer goods is critical to delivering high-quality products while optimizing operating costs. One of the most innovative advances in these technologies is the use of servo-driven plastic injection molding machines, which offer many advantages and differences over traditional hydraulic systems. Below, we share the key benefits of Topstar’s servo-driven plastic injection molding machines, their technical features, and why they are the right choice for your precision manufacturing process.

Improve Energy Efficiency with Servo Drive

One of the most obvious advantages of using servo-driven technology is its improved energy efficiency. Unlike traditional hydraulic presses that run continuously, servo-driven machines adjust their energy consumption according to process needs. Servo motors control the movement of the injection unit and clamping system, allowing precise control of speed, pressure, and position. This real-time adjustment means that energy is only used when necessary, reducing total power consumption by up to 30-80% compared to standard hydraulic presses. For manufacturers, this can save a lot of electricity costs.

Improved precision and control in plastic injection molding

In the medical field or electronics, even the slightest deviation in the molding process can lead to defective or rejected parts. Servo-driven plastic injection molding machines offer precision and control over traditional hydraulic systems. Servo motors can provide precise positioning and motion control, making the injection, clamping and ejection processes more accurate. This high level of control allows for more excellent repeatability, ensuring the same quality for every part produced. Topstar’s proprietary servo drive technology can adjust factors such as injection speed, pressure, and clamping force in real-time, allowing manufacturers to fine-tune the process to meet exact specifications.

Servo-driven plastic injection molding machine reduces cycle times

Another significant benefit of servo-driven plastic injection molding machines is the ability to achieve faster cycle times. The servo motors can quickly accelerate and decelerate machine motion. At the same time, the new oblique hinge layout allows for ultra-long mold opening, which reduces mold opening and closing times, speeds up injection speeds and improves ejection process efficiency. This increase in speed can significantly reduce the total cycle time per part, thereby increasing production capacity. For manufacturers in high-volume manufacturing industries such as automotive, the ability to produce more parts in less time can provide a substantial competitive advantage. In addition to speeding up the production process, servo drives also provide smoother transitions between the different stages of the molding cycle. This reduces wear on machine components and extends the life of the equipment.

Servo-driven plastic injection molding machines are more flexible and versatile

Flexibility is essential for manufacturers who produce multiple products or frequently change molds for production. Plastic injection molding machines using servo drives are highly flexible, and the new mold adjustment mechanism can achieve automatic and precise mold adjustment with one click, allowing manufacturers to easily switch between different molds, materials and processes without a lot of adjustments or reconfigurations.

The precise control provided by servo drive technology enables it to handle a variety of plastic materials, including high-performance engineering plastics that require specific processing conditions. This versatility allows manufacturers to use the same plastic injection molding machine to produce parts for multiple industries, such as automotive, electronics, medical and consumer goods. At the same time, Topstar’s servo control technology can also be highly integrated with other auxiliary machine systems, allowing users to obtain auxiliary equipment operating data directly on the injection molding machine and making operation more convenient.

It can target a variety of process technologies for specific industry equipment, such as robot end jitter suppression, multi-pump converging/dividing hydraulic control, and multi-axis coordinated synchronous control.

Improved Product Quality

One of the main ways servo-driven machines improve product quality is through precise control of the molding process. By precisely controlling injection speed, pressure, and cooling time, manufacturers can minimize common defects such as flash, warping, and short shots. Servo drives also provide better control of clamping force, ensuring the mold remains tightly sealed during injection and preventing problems such as material leaks or incomplete fill. The improved repeatability of servo-driven machines means manufacturers can produce a large number of parts with consistent quality, reducing the number of rejected parts and minimizing waste.
