GW/S Series Servo Plastic Injection Molding Machine
A comprehensive series of servo-driven plastic injection molding machines, offering clamping forces from 700 kN to 10,000 kN. Designed for energy efficiency and precision, these machines provide A/B/C screw configurations to suit various plastic materials and product requirements.

Why Choose the GW/S Series Servo Injection Machine
Energy-Saving Servo System
Equipped with a high-performance servo motor. The servo drive precisely matches power output to the actual molding demand, significantly reducing energy consumption compared to traditional hydraulic systems.
Extensive Tonnage & Screw Options
With clamping forces ranging from 700 kN to 10,000 kN and A/B/C screw diameter options for most models, you can precisely match the machine to your specific mold size and material characteristics.
High Precision & Repeatability
The servo control ensures highly accurate injection speed and pressure. Combined with a robust clamping unit, it delivers consistent part quality, tighter tolerances, and reduced reject rates.
About This Servo Plastic Injection Molding Machine
The GW/S series is a versatile line of servo plastic injection molding machines designed to meet the demands of modern plastic manufacturing. From the compact GW78/S to the large-scale GW1000/S, this series covers a vast array of production requirements.
At the heart of the machine is the servo motor system. By replacing traditional constant-speed motors, the servo system only consumes energy when the machine is actually performing work (injection, clamping, ejecting). This results in substantial energy savings, especially during the cooling phase, while providing faster response times and more precise control over the molding process.
To accommodate different materials and product designs, the GW/S series offers A, B, and C screw configurations for most models. This allows manufacturers to optimize the injection unit for specific shot weights, injection pressures, and plasticizing capacities, whether processing standard plastics, engineering plastics, or high-precision parts.
The machines feature a rigid clamping unit with a wide tie-bar space (up to 1100*1100 mm on the largest model) and generous mold thickness capacities. This ensures stability and precision even when running heavy molds or high-cavitation tooling.
If you require a reliable, energy-efficient, and highly adaptable injection molding solution, the GW/S series provides a model for virtually any plastic molding application.
Please contact us with your specific product requirements, mold dimensions, and material type to determine the optimal machine size and screw configuration.
