How to adjust the parameters of Haitian injection moulding machine MA1600 to reduce energy consumption?

The following are the specific methods and steps for adjusting the parameters of Haitian injection moulding machine MA1600 to reduce energy consumption, combined with the characteristics of the machine and industry experience:

I. Activate energy saving mode

1. Activate ECONOMY mode 

   - Go to ‘System Settings’ in the control panel, select ‘Energy Saving Mode’ and turn it on. This mode will reduce the power output of non-essential actions (such as standby pump speed down to 50%).  

   - Effect: It can reduce energy consumption by 10%-15%.

2. Dynamic Response Control

   - Enable ‘pressure/flow closed-loop control’ to adjust the oil pump output in real time through the sensor to avoid excess pressure.  

   - Path: Main interface→Parameter setting→Hydraulic control→Closed loop mode.

Optimising injection and pressure maintaining parameters

1. Optimise the injection speed in stages 

   - Filling stage: reduce the initial injection speed from 100% to 70%-80% to reduce the instantaneous power peak.  

   - Pressure holding phase: use multi-stage pressure holding, e.g.:  

   - Pressure holding stage 1: 80% pressure (30% time share)  

   - Pressure holding stage 2: 60% pressure (50% of time)  

   - Holding pressure stage 3: 40% pressure (20% of time)  

   - Tool: Use the built-in ‘Injection Speed Curve Editor’ of Haitian injection moulding machine for graphical adjustment.

2. Reduce holding pressure and time  

   - Determine the minimum holding pressure through mould flow analysis (e.g. Moldflow), which can usually be reduced by 15%-20%.  

   - Case: If the original holding pressure is 120MPa, try to reduce to 100MPa and observe the product quality.

Cooling and temperature control

1. Dynamic cooling management  

   - Enable ‘mould temperature dynamic compensation’, according to the production cycle automatically adjust the cooling water flow.  

   - Operation: Enter ‘Mould Settings’ → Check ‘Intelligent Cooling’. 2.

2. Reduce cooling time 

   - Reduce the cooling time by 10%-15% by optimising the mould water circuit design or using mould materials with higher thermal conductivity.  

   - Verification method: Record the cooling time and product demoulding temperature for 10 consecutive moulds to ensure that the demoulding temperature is ≤ the ejector deformation threshold (usually ≤ 60℃).

Fourth, plasticising and back pressure adjustment

1. Optimisation of screw speed 

   - Reduce the screw speed from 60rpm to 45-50rpm, and extend the plasticising time (e.g. increase 1-2 seconds).  

   - Formula: Plasticising time (sec) = Injection volume (g) / (screw speed x screw cross-section area x melt density).

2. Back pressure control 

   - Reduce the back pressure from 8-10MPa to 5-6MPa to reduce the energy consumption in the plasticising stage.  

   - Note: It is necessary to ensure that the melt is uniform and there is no bubble or discolouration problem.

V. Other parameters adjustment

1. Optimisation of mould opening and closing speed  

   - Reduce the fast mould opening speed from 150mm/s to 120mm/s to reduce the mechanical impact energy consumption.  

   - Balance method: Compensate the speed loss by increasing the slow section stroke (e.g. extend the slow mould opening stroke from 50mm to 80mm).

2. Ejector pin movement simplification 

   - Eliminate the unnecessary ejector delay time and increase the ejector return speed from 80mm/s to 100mm/s.

VI. Verification after parameter adjustment

1. Energy consumption data comparison 

   - Use the built-in ‘Energy Consumption Statistics’ function of Haitian injection moulding machine (Path: Main Interface → Production Monitoring → Energy Consumption Report) to compare the average energy consumption of 3 working days before and after adjustment.  

   - Target: Achieve 15%-25% reduction in energy consumption per unit product.

2. Product quality confirmation  

   - Check whether there are problems such as flying edge, shrinkage, size deviation, etc. in the adjusted products, and fine-tune the parameters if necessary.

VII. Precautions

1. Step-by-step adjustment: adjust only 1-2 parameters each time to avoid multivariate interference.  

2. Professional support: complex parameters (such as PID parameters) need to contact Haitian technical staff for optimisation.  

3. Regular calibration: Use tools such as pressure gauges and flow meters to verify parameter accuracy every 6 months.

With the above adjustments, the energy consumption of Haitian MA1600 injection moulding machine can be significantly reduced while maintaining productivity and product quality. It is recommended to combine with servo system upgrading (e.g. replacing the dosing pump with servo pump) to further improve the energy saving effect.
