The final stage of the cycle is ejection, where the solidified plastic part is removed from the mold. First, the clamping unit releases the mold: the moving half of the mold pulls away from the fixed half, creating space between the two halves. Next, ejection systems—typically small pins, plates, or air blasts—push or blow the finished part out of the mold cavity. The ejection force is gentle enough to avoid damaging the part but strong enough to overcome any friction between the plastic and the mold’s surface.
After ejection, the mold closes again, the screw rotates to feed and melt a new batch of plastic pellets, and the entire cycle repeats. The speed of the cycle (from feeding to ejection) varies by part size and plastic type but typically ranges from 10 seconds (for small, simple parts) to several minutes (for large, complex parts). High-speed injection molding machines can complete cycles in under 5 seconds for ultra-small components like medical micro-connectors.
Throughout the entire process, the injection molding machine’s controller plays a central role in maintaining precision. Operators set parameters like barrel temperature, injection pressure, holding time, and cooling time via a touchscreen interface. Modern machines often integrate sensors that monitor real-time data (e.g., melt temperature, mold pressure, screw position) and adjust parameters automatically to correct deviations—reducing human error and ensuring consistent quality. For example, if a sensor detects that the melt temperature is too low, the controller will increase the barrel heater output to compensate.
In summary, the working principle of injection molding machines is a harmonious blend of heat, pressure, and precision control. By cycling through material melting, injection, clamping, cooling, and ejection, these machines transform simple plastic pellets into millions of the products we use daily—from toy parts to life-saving medical devices. As technology advances, innovations like electric drives (replacing hydraulic systems for faster, more energy-efficient operation) and IoT integration (for remote monitoring) continue to refine this process, making injection molding even more versatile and sustainable.
