INJECTION MOLDING MACHINE: Energy-efficient injection molding solution
1. Product features
High-precision control
Servo injection molding machine drive system, repeat positioning accuracy can reach ±0.03mm, product weight error is controlled within 0.5%. The closed-loop control system adjusts the pressure, speed and position parameters in real time to ensure the stability of the molding process.
Energy saving and high efficiency
Compared with traditional hydraulic injection molding machines, it saves 50%-80% energy, the response time is less than 0.05 seconds, and the molding cycle is shortened by 15%-30%. The servo motor supplies energy on demand and stops running completely when in standby mode to avoid energy waste.
High precision and high response
Adopt high-precision and high-sensitivity pressure sensors and rotary encoders to achieve closed-loop control of pressure and flow, with a repeat progress error of less than 1%, and the servo motor takes only 0.05 seconds to reach the maximum output power.
2. Working Principle
The operation of the servo injection molding machine is based on the coordinated work of four major systems:
Power system
The servo motor directly drives the screw, with an energy conversion efficiency of more than 95%, and the speed is precisely controlled through encoder feedback (error ±1rpm).
Injection molding process
It is divided into five stages: plasticization, injection, pressure holding, cooling, and ejection. The pressure/speed of each stage can be independently programmed. For example, the pressure holding stage is fed back in real time through the pressure sensor to dynamically adjust the servo motor torque.
Temperature control system
Adopts multi-stage PID temperature control (temperature difference ±1℃), combined with heating coil and water cooling dual mode, to meet the processing requirements of different materials such as PC and PA.
Intelligent control
The servo drive and PLC controller are connected with CAN bus to realize the synchronous control of opening and closing molds, injection, melting and other actions, shortening the production cycle.
3. Core advantages
Significant economic benefits
Energy consumption costs are reduced by more than 60%, and the hydraulic oil replacement cycle is extended by 3 times
Scrap rate can be controlled below 0.5%, and the equipment life is 8-10 years
Outstanding performance advantages
The response speed is 2-3 times that of traditional machines, suitable for the production of precision parts (such as medical catheters, electronic connectors)
Noise ≤70dB, more friendly working environment
Strong application flexibility
Thin-wall packaging with a wall thickness of 0.1mm or large parts weighing up to 5kg can be produced through rapid parameter switching
Clean room compatible design meets medical and food grade production requirements
4. Key points for later maintenance
Daily maintenance
Check guide rail lubrication (ISO VG68 lubricant recommended) and belt tension daily
Clean barrel residue and mold cooling water channel every week to prevent blockage
Maintenance of key components
Servo motor: Check encoder connection status every 2000 hours
Screw barrel: Measure wear clearance every 5000 hours (standard ≤0.2mm)
5. Precautions for use
Safety regulations
The mold must be powered off during installation, and the parallelism must be corrected with a dial indicator
Low-temperature startup is strictly prohibited (the material must reach the set melting temperature)
Environmental requirements
Workshop temperature 15-35℃, humidity ≤70%RH
The power supply voltage fluctuation must be controlled within ±5%, and a voltage stabilizer is recommended.
