Why are electric injection molding machine ideal for the medical field?

The medical field requires precise manufacturing processes to produce high-quality parts with strict tolerances. Compared with traditional hydraulic injection molding machines, the most significant advantage is the accurate control that electric injection molding machines can provide. These machines use electric servomotors to control the entire injection process, from clamping force to speed, allowing for precise and repeatable motion.

Another advantage is cleanliness. The fact that fully electric machines do not require hydraulic oil also means that fully electric injection molding machines are quieter and more energy efficient, eliminating the risk of oil leaks and contamination. This is particularly important in medicine, where maintaining cleanliness and sterility is essential.
At the same time, their ability to precisely control the injection process reduces cycle times, significantly increasing production capacity.

Core features of Topstar electric injection molding machine

Servo self-drive and ultra-low speed operation

At the heart of Topstar electric injection molding machines is the self-developed servo self-drive system, which can control the various movements and functions of the machine with extremely high precision. Unlike traditional hydraulic systems that rely on fluid pressure and valves, the servo self-drive system can directly and accurately control injection speed, pressure, and position. In addition, servo self-drive technology helps improve the machine’s overall energy efficiency. By using electricity only when needed, the system minimizes energy waste.

Ultra-low speed operation enables them to carefully control the material flow into the mold when producing thin-walled parts or complex components, eliminating undesirable defects such as product flow marks. By reducing the injection speed, the machine ensures that the material fills the mold completely and evenly, producing higher-quality parts with less scrap.

High-precision pressure control and low-damping injection unit

The high-precision pressure control system accurately regulates the pressure during the injection process and ensures that the molten material delivers the required force to the mold cavity. When it comes to medical plastic parts, by maintaining optimal pressure throughout the injection cycle, Topstar’s machines help prevent common defects such as sink marks, voids, or flashes, which can occur when pressure is too high or too low.

The low-damping design minimizes the resistance encountered by the injection screw as it moves forward, allowing for more consistent and controlled delivery of material into the mold. The benefits of the low-damping injection unit are particularly evident in applications that require high-speed injection or when processing materials with challenging flow characteristics. The machine can maintain a steady injection speed by reducing the damping effect, improving part stability.

High-performance holding pressure capability of electric injection molding machine

High-performance holding pressure capability ensures that the pressure applied during the injection process remains consistent, even after the initial injection phase. Pressure maintenance is critical to ensure that the molten material fills the mold cavity correctly, especially in areas where the material may begin to cool and solidify prematurely. When producing medical products, pressure changes can cause defects such as sink marks, voids, or warping. By maintaining consistent pressure throughout the holding phase, electric injection molding machines help ensure the final product meets strict quality standards and improve the ability to mold thick-walled products in one go.
