Injection Molding Machine 20-1

Injection molding machines enable manufacturers to produce a wide range of products with complex designs and high precision. As technology advances, injection molding machines evolve and incorporate new features to improve performance, reduce operating costs, and enhance product quality. In this article, we will share with you the four significant features of injection molding machines that make injection molding machines indispensable in today’s manufacturing environment. These features are non-contact tie rods, lubrication-free tie rod mechanisms, low-damping injection units for precise metering, and high-rigidity, low-friction mechanical structures. Each component ensures that the injection molding machine operates efficiently, accurately, and cost-effectively.

Injection molding machine: non-contact tie rods for improved precision

One of the outstanding features of modern injection molding machines is the non-contact tie rods. Traditional injection molding machines often rely on mechanical tie rods to connect different machine parts. Still, over time, these parts will wear out, reducing the efficiency and precision of the machine. However, non-contact tie rods eliminate this problem using a design that does not require physical contact between the tie rod and other parts. Using non-contact tie rods ensures less friction between moving parts, reducing wear and tear on the machine. At the same time, it also makes the movement of the injection unit smoother and more precise, thereby improving the overall accuracy of the molding process. By reducing the effects of friction and wear, non-contact tie rods increase the machine’s durability and help maintain high precision.

Injection molding machine: lubrication-free tie rod mechanism

The tie rod in the injection molding machine is essential to its operation because it helps stabilize and support the moving parts during the molding process. The tie rod must be lubricated regularly to ensure smooth operation and prevent excessive friction. However, modern injection molding machines have adopted a lubrication-free tie rod mechanism that does not require constant lubrication while maintaining optimal performance. This feature can significantly reduce maintenance time and costs because there is no need to check or change lubricants regularly. In addition, the lubrication-free design prevents contaminants from entering the molding process, ensuring cleaner production and higher-quality products. By reducing the reliance on lubricants, manufacturers can reduce operating costs and improve the overall efficiency of the production process. In addition, they are particularly beneficial in cleanroom environments.

Low-damping injection unit for precise metering

Precision is crucial in injection molding because the success of the molding process often depends on the exact amount of material injected into the mold. Injection molding machines with low-damping injection units have significant advantages in this regard. Low-damping injection units are designed to provide consistent and precise material metering, essential for producing high-quality products with tight tolerances. The damping characteristics of the injection unit affect the speed and accuracy of the injection process. High damping can cause injection rate fluctuations, leading to inconsistent part quality and increased scrap rates. By incorporating low-damping injection units, modern machines ensure that material is injected at a steady, controlled rate, reducing the likelihood of defects such as inconsistent wall thickness or flow marks.

High-rigidity, low-friction mechanical structure

The mechanical structure of an injection molding machine plays a vital role in its overall performance. A high-rigidity, low-friction mechanical structure ensures that the machine can withstand the stress of the molding process while maintaining accuracy. The frame’s rigidity prevents deflection during operation, ensuring that the mold remains perfectly aligned throughout the injection cycle. This alignment is essential to achieving accurate and consistent part quality.

The low-friction design of the mechanical structure also reduces wear on moving parts, extending the life of the injection molding machine and reducing maintenance costs. The combination of high rigidity and low friction allows modern injection molding machines to produce high-precision parts with minimal distortion or variation. This feature is particularly beneficial in applications that require fine details or tight tolerances, such as in the automotive or aerospace industries, where precision is critical to product performance and safety.

High-rigidity, low-friction mechanical structure

Servo self-driven motors for stable operation

Servo self-driven motors enable extremely low and stable operating speeds. This motor technology eliminates the need for traditional hydraulic systems, which are often inefficient and unstable. Servo motors operate with high precision and can operate smoothly and stably even at low speeds.

This feature improves the machine’s overall energy efficiency and helps achieve more consistent molding results. The precise control of the servo motor ensures that the injection process is carried out with minimal fluctuations, which is essential for eliminating product flow marks and achieving a high level of surface finish. In addition, the reduced operating speed helps minimize noise and vibration, making the injection molding machine more comfortable to operate and less prone to mechanical wear.

Maximize efficiency with these features.

From non-contact tie rods and lubrication-free systems to low-damping injection units and servo motors, these features improve the machine’s overall performance, resulting in improved energy efficiency, reduced maintenance costs, and improved product quality. Investing in an injection molding machine with these advanced features can provide a significant competitive advantage.
