Product Information

Product Category： Injection Molding Machines

D series electric injection molding machine

Self-locking five-point toggle clamping for industry-leading clamping rigidity Servo-driven ball screws for smooth, precise movement Advanced motor drive and control system with repeatability up to ±0.01 mm Premium components for outstanding machine stability Grease lubrication reduces hydraulic oil consumption, noise, and energy use for greener production
Product Category： Injection Molding Machines

SeF Series Servo Energy Saving Thin-wallHigh Speed Special Injection Moulding Machine

Maximum injection speed of 555 mm/s, with single-cylinder high-speed injection and plasticizing, high-response servo-hydraulic drive and advanced control system—ideal for thin-wall packaging applications. Synchronized plasticizing shortens dry cycle time and boosts production efficiency. High-strength, low-strain clamping structure withstands demanding high-cycle production, while proportional valve control ensures precise, stable and reliable machine movements. Advanced flow-diversion and merging design enables intermittent unloading of the servo motor and pump during high-speed molding, reducing energy consumption and component fatigue while extending machine service life.
