Haichen machine power consumption varies depending on machine type, size, and operating conditions.
All-electric machines tend to be more energy-efficient than hydraulic or hybrid machines, potentially offering significant savings, especially in high-volume production.
Factors like cycle time, material type, and mold design also influence energy usage.
Power consumption of Haichen injection molding machines
Injection molding machines are key equipment in the injection molding production process, converting raw materials into finished products through various mechanisms.
Among them, the type and size of the injection molding machine will significantly affect its power consumption.
Hydraulic presses that use hydraulic systems for mold locking and injection usually consume more electricity than pure electric motors.
The cycle time during the injection molding process will also directly affect power consumption.
A longer cycle time will lead to an increase in energy consumption for the production of each component.
In addition, injection molding machines also consume a certain amount of energy and electricity during the heating and cooling processes.
How is the power consumption of an injection molding machine calculated per hour?
First of all, we will determine the power consumption of each component of the injection molding machine.
Including the hydraulic system, the motor, the auxiliary equipment of the injection molding robot, etc.
Next, we determine the energy consumption of each component at different stages of the injection molding process.
For example, heating, injection and cooling during the molding cycle.
Once you know the power consumption of each component, you can calculate the total energy consumption of the injection molding machine within a given time period (usually in hours).
The optimal power consumption per hour is to add up the power consumption of all components.
And then multiply it by the operating time (power consumption (kilowatt-hours) = power consumption rate (kilowatts) x cycle time).
Haichen machine power consumption of different types
- All-electric injection molding machines
- Hydraulic injection molding machines
All-electric injection molding machines
These machines are usually highly energy efficient, with a Power consumption of about 0.5 kWh per hour.
According to another study, the average Power consumption per kilogram of polymer in an all-electric injection molding machine is 4.8 MJ (about 1.33 kWh/kg).
Hydraulic injection molding machines
These machines have a high Power consumption of around 2.5 kWh per hour.
According to another study, the average Power consumption per kilogram of polymer in a machine is 11.3 MJ.
Hybrid injection molding machine: combines the advantages of hydraulics and electricity, with Power consumption in between, around 3-4 kWh per hour.
Haichen machine power consumption calculations
- All items of the power consumption calculation formula
- Calculation of power consumption
- Calculation of comprehensive Power consumption per unit of product
All items of the power consumption calculation formula
E represents comprehensive power consumption, measured in kilograms of standard coal.
n denotes the total number of energy types consumed.
Eᵢ indicates the physical quantity of energy used in production activities during the same period.
Pi is the scaled factor for the ith energy source.
Calculation of power consumption in injection molding process
According to this, the power consumption of the injection molding process can be calculated by the following formula: Ee=Ez
Ee is the power consumption of the injection molding process, in kilowatt-hours (kWh).
Ez is the injection molding machine consumption in kilowatt-hours (kWh).
Calculation of comprehensive Power consumption per unit of product
According to this, the comprehensive Power consumption per unit of product can be calculated by the following formula: e=E/G
e is the comprehensive Power consumption per unit of product, and the unit is the kilogram of standard coal per ton (kgce/t)
E is the comprehensive Power consumption in kilograms of standard coal (kgce).
G is the total output of products in tonnes (t) during the statistical reporting period.
Power consumption = (heating power, motor power) ×60% Power consumption = (16KW 30KW) ×60% = 46KW×60% = 27.6 degrees
Taking Haichen 280 tons injection molding machine as an example, the heating power is 16KW, the motor power is 30kw, and the actual power consumption is about 27.6 kWh.
Haichen’s energy-saving measures
Use of high-efficiency motors and frequency converters: Reduce unnecessary Power consumption by precisely controlling the motor speed.
Optimized heating and cooling systems: Power consumption can be significantly reduced with advanced heating and cooling technologies.
Intelligent control system: Sensors and IoT devices are used to monitor and adjust production parameters in real-time to optimize Power consumption.
