Features of the LK POTENZA-II Energy-Saving Servo Injection Molding Machine

• Hydraulic unit applied Europe/Japan imported oil valve with advanced seals to reduce piping and prevent leakage.
• Worldwide brand, powerful hydraulic motor offer higher torque and performance.
• Europe/USA imported, fast and reliable gear type mold height adjustment mechanism.
• The compact injection unit is driven by hydraulic system. Which is user-friendly and easy to maintenance.
• Centralized automatic toggle lubrication system ensure fixed volume of lubricant deliver to each moving point with adjustable cycle time, which increase the lifetime and reduce maintenance.
• Equips with advanced computer system and user-friendly interface, which enhance mold date memory system and can show SPC production parameters. Closed loop control can be chosen which integrates high performance and easy operation features.
• Servo systemwith closed loop control, which meet the requirement of low pressure with high torque, faster ACC/DEC time, stable speed control and designated stop function.
• Lightweight and small size precision oil filter driven by mechanical power, equipped with special flow regulator, which ensures the stability and precision of the filter. Easy to install, operate and maintain.
• European linear transducer control for mold-clamping, injection and ejector action, stroke control up to 0.1mm accuracy.
• Hydraulic oil return to the oil tank through the oil cooling device to ensure the stability of the oil temperature.
• Extreme Power Saving: Compared with the variable displacement pump system, servo system, which is designed base on the needs of every injection step, power saving up to 30%-80%. Servo system can control the speed and torque of the servo motor automatically to make the operation smoothly.
• Closed-loop Control: In order to meet the speed and pressure requirement of the machine, hydraulic system is controlled by motor operation speed and torque, which are monitored by speed encoder and pressure sensor, to make corrections to the servo system according to the feedbacks, so as to achieve consistently with the input & output of the flow and pressure.
• High Response:: The pressure and flow of variable pump system are controlled by proportional valve and swash plate of the pump with response time around 0.12s~0.15s. On the other hand, the pressure and flow of hydraulic system are controlled by hydraulic servo motor with high response time of 0.03s, which with optimize design and improve productive efficiency.
• High Precision:: High precision speed control up to 1/1024 rpm accuracy as well as high precision position control for the servo system motor.
• Good Quality of Plasticizing: In order to improve the quality and competitiveness of the product, LK servo injection molding machine adopted good quality and good mixing effect screw as standard configuration.
• Low Oil Temperature: Compare with hydraulic system, overflow problem of unloader valve and proportional valve happen in FDP & VDP system and cause the loss of system pressure, hydraulic system can variable control the pressure and quantity of flow to reduce pressure loss, cooling water consumption save.
• High Performance Under Low Speed: Creeping and impulsive phenomenon will not happen under low pressure and flow working status, high performance and stability.
