High-speed injection molding machines are a specialized type of injection machine, characterized primarily by their exceptionally high injection speeds, making them ideal for rapidly producing thin-walled, miniature, or highly precise plastic parts. ### I. Core Definition and Key Features **Core Metrics:** - Injection speed typically exceeds 300 mm/s (with some advanced models reaching over 1,000 mm/s), - Injection acceleration is ≥1,000 mm/s²—significantly higher than standard injection machines (usually ≤200 mm/s). **Core Functionality:** By delivering molten material at ultra-fast rates, these machines effectively address the challenges associated with thin-walled components (wall thickness ≤1 mm), where rapid cooling and short flow distances can lead to issues like insufficient filling or sink marks. This ensures flawless part quality while maintaining production efficiency. ### II. Core Technological Support **Power System:** Most high-speed machines rely on fully electric or servo-hydraulic drives, paired with highly responsive servo motors and precision ball screws to ensure stable, high-speed operation. **Injection Mechanism:** Optimized screw and barrel designs minimize melt flow resistance, while short-stroke injection cylinders enhance responsiveness. Some models even feature dual-injection cylinder configurations to further boost power and performance. **Control System:** Advanced closed-loop control technology enables millisecond-level adjustments of both injection speed and pressure, preventing melt fracture during high-speed filling processes. ### III. Typical Application Scenarios **3C Industry:** Thin-walled, precision plastic components such as mobile phone casings, charger housings, and earphone accessories. **Packaging Industry:** Mass-produced, high-speed manufacturing of items like disposable cutlery, beverage bottle caps, and lightweight packaging containers. **Medical Industry:** High-precision medical devices, including miniature medical components and thin-walled syringe assemblies.
