The Five Elements of Injection Molding Technology
By Nice Rapid | Jun 02 , 2020

The first thing we need to know is that the injection pressure is provided by the hydraulic system of the injection system. The pressure of the hydraulic cylinder is transmitted to the plastic melt through the screw of the injection molding machine. The plastic melt is driven by the pressure and enters the mold through the nozzle of the injection molding machine. The vertical flow channel, the main flow channel, the split flow channel, and enter the mold cavity through the gate, this process is injection molding.

The following five elements of injection molding

1. Temperature: material barrel temperature, material temperature, mold temperature, dry out and oil temperature, environment temperature etc... 


2. Pressure: injection molding pressure, keeping pressure, backpressure, demolding pressure, build-mold pressure and lock-mold pressure etc... 


3. Time: Injection time, holding time, cooling time, drying time, metering delay time etc…


4. Speed: Injection speed, carriage return speed, mold opening and closing speed, demolding speed, etc.


5. Position: measuring position, ejecting position, mold opening position etc…

These five elements of the injection molding process are indispensable. Any value affects the quality of the plastic products, so the technology of the injection molding master is also very important.
