Electric injection molding machines use motors to drive all injection molding movements and processes, and have many advantages over traditional hydraulic injection molding machines.

Characteristics of electric injection molding machines and advantages over traditional hydraulic injection molding machines

1. High precision and efficiency

Electric injection molding machines have higher precision and are suitable for the production of products with higher precision requirements. The response speed is fast, the molding cycle is shorter, and it is suitable for high-volume production.

2. Stable control

Electric injection molding machines can achieve stable speed, pressure and position control through precise servo motor control, thereby improving product quality.

3. Easy maintenance

Because there is no complex hydraulic system, the maintenance of electric injection molding machines is relatively simple, which also reduces the risk of hydraulic failures such as oil leakage.

4. Energy saving and environmental protection

The energy consumption of electric injection molding machines is much lower than that of hydraulic injection molding machines, especially in the cooling stage, where no energy is wasted. There is no hydraulic system, so no oil cooling is required, reducing contamination and oil maintenance costs.

5. Low noise

Electric injection molding machines have low noise during operation and are suitable for use in production sites with high environmental requirements.

Instructions for using electric injection molding machine

1. Environmental requirements

Temperature control: Electric injection molding machines are sensitive to temperature. It is recommended to work in an environment with suitable temperature to avoid the impact of high or low temperatures on electrical components. Clean and dust-proof: Keep the work area clean to prevent dust from entering the mechanical and electrical systems. Especially the guide rails and screw positions of machine tools need to be cleaned regularly to prevent foreign matter from entering.

2. Electric power stability

Electric injection molding machines have high voltage requirements and need to ensure stable power supply to avoid damage to the machine due to voltage fluctuations or sudden power outages. If the voltage in your area is unstable, it is recommended to use a voltage stabilizer to protect the electrical system.

3. Cooling system maintenance

Although electric injection molding machines do not have hydraulic cooling, the servo motor and control system still need to be cooled to ensure that the temperature is within an appropriate range to avoid system overheating.

4. Regular

lubrication Moving parts such as servo motors and ball screws require regular lubrication to ensure smooth operation, reduce wear and extend machine life.

5. Preheating and cooling operations

Preheating should be carried out before starting up, especially when working in a cold environment, to ensure that all parts of the equipment are at the appropriate temperature. When shutting down, the machine should be allowed to cool down for a period of time, especially after continuous high-load operation, to prevent high temperature from affecting the life of components.

6. Parameter setting

Ensure that parameters (such as injection speed, holding pressure time, etc.) are set reasonably and avoid settings that are too high or too low to reduce equipment load and extend service life. Especially when changing products or materials, process parameters need to be readjusted to ensure that the machine is in optimal condition.

7. Safe operation

Electric injection molding machines should be operated by trained personnel to avoid mechanical failures or safety accidents caused by misoperation. Regularly check the safety protection device of the machine to ensure that the machine is working within the normal range.

8. Regular maintenance

Regularly check the performance of servo motors, electrical systems and control units to ensure normal operation of the system. Check the condition of each connecting cable and plug to avoid looseness or damage.

9. Material and mold compatibility

When using different plastic materials, make sure the materials are suitable for the temperature and pressure requirements of the electric injection molding machine. Ensure that the mold is installed and fixed stably to prevent vibration during the injection molding process from affecting machine accuracy.

10. Emergency response

Be familiar with the emergency stop device of the electric injection molding machine, which can shut down the machine immediately in the event of an emergency to prevent further damage to equipment or personnel.

Application fields of electric injection molding machine

1. Electronic and electrical products

Used to manufacture various types of electronic product casings and components, such as mobile phone casings, computer casings, connectors, etc. The high-precision control of the electric injection molding machine enables it to meet the strict requirements for size and appearance of electronic products and reduce the defective rate.

2. Medical devices

It is suitable for the production of precision medical supplies, such as syringes, test tubes, catheters and other medical equipment that require extremely high hygiene and precision. No hydraulic oil is required, which reduces the risk of oil contamination and is more in line with the cleanliness requirements in the medical field.

3. Optical products

Suitable for the production of high transparency and precision optical components such as camera lenses, LED lenses, optical lenses, etc. The stability of the electric injection molding machine ensures that the product is bubble-free and flow-mark-free, and improves optical performance.

4. Auto parts

Used to produce automotive interior parts, instrument panels, connectors and other components that require high strength and precision. The high repeatability of electric injection molding machines facilitates strict dimensional control of parts, improving the reliability and consistency of automotive parts.

5. Food and packaging industry

It is suitable for the production of products with high requirements on hygiene and safety, such as food containers, pharmaceutical packaging bottles, beverage bottle caps, etc. The environmental protection and cleanliness of electric injection molding machines meet the standards of the food and packaging industry.

6. Precision engineering products

It is widely used in high-end engineering products, such as laboratory instrument components, industrial robot shells, small mechanical parts, etc. The stability and controllability of the electric injection molding machine enable it to produce high-precision and high-quality engineering plastic parts.

7. Home appliances

Suitable for the production of home appliance casings and parts, such as washing machine casings, TV frames, air conditioning panels, etc. The electric injection molding machine has a short molding cycle and is suitable for mass production of home appliance components to ensure dimensional consistency.

8. Cosmetic packaging

It is used to produce packaging products with high appearance requirements such as cosmetic bottles, bottle caps, and containers. The electric injection molding machine can achieve a molding effect without flash and smooth surface, which meets the aesthetic requirements of cosmetic packaging.

9. Precision thin-walled parts

It is suitable for the production of precision parts that require extremely thin wall thickness, such as instrument panels and electronic equipment casings. Electric injection molding machines can accurately control injection speed and pressure to ensure the stability and quality of thin-walled parts molding.

Summarize

Electric injection molding machines have the characteristics of high precision and efficiency, but their initial costs are high. They are suitable for production environments with high product quality requirements, strict environmental protection and cleanliness requirements, and are suitable for long-term production applications.
