Main Parts of Injection Molding Machine
As we know, most of injection molding machine have 3 main parts: Machine`s Frame, Injection Unit & Clamping Unit. The machine`s controlling system connect these injection molding machine parts together to an injection machine. But fewer people knows how many components of injection molding machine have. As a prefessional injection molding machine manufacturer, today we would like to talk this topic and help more people to understand plastic injection machines better.
Frankly speaking, there are hundreds to more than a thousand components are assembled in an injection moulding machine. The number is not a solid word depends on the manufacturer, tonnage size and functions of plastic injection machine. There are dozens to hundreds parts difference for some different injection plastic machine.
Let`s make a sample with our Guanxin machinery`s different models. Our 160 ton small injection molding machine have about 500 kinds parts (more than 1300 pcs parts) on BOM list, but there are 700 kinds parts ( more than 1500 pcs parts) for our 1000 ton injection molding machine. And it`s with our standard configurations only, there are more if have some other part for different regions and countries used. We may need to add voltage stabilizer for Africa used, and voltage regulating transformer for some other countries not in 380V power. And that will cause many auxiliary coms is installed together.
Injection Molding Machine Parts and Functions
Below we will try to explain more about injection molding machine parts and their functions. We slide it into few main parts of injection machine for easies understand: The clamping unit, injection unit, electronic unit, hydraulic system, protecttion guard parts. These parts are named by there fuctions on an plastic injection molding machine. And it`s most known by people worldwide.
The clamping unit`s function is to hold the plastic mold and offer the clamping force for mold holding pressure when the molten plastic injected into the mold.
The injection unit`s function is used to melt the granule plastic and mixed with colorant and inject it to the plastic injection molding mold. The electronic unit is the control system of injection plastic machine, you can think it as the brain of the machine and offer the interface to human.
The hydraulic system turns the power from electric motor to mechanism movings, it`s the power supply chain on an plastic molding machine.
The protection guard is used to protect the machine from damage and keep human in safe for the machines movement and accidants.

Injection Molding Srcew and Barrel Parts and Functions
The parts of injection molding screw are screw body, screw rocket head, chuck ring and stop ring. The crew rocket head, chuck ring and stop ring are called as injection molding screw tip or 3 small parts by most of plastic molding machine manufacturers.
There are many parts for the barrel as well: injection molding barrel, barrel bracket, fasten bolts and nozzle head.
Injection Molding Machine Parts Name
We found some friends are searching the plastic injection molding machine parts or even for all the parts names. I think thats meaning less to list all the names as there are hundreds names. And it may be an eldless list due to there are lost of funcions are added onto the plastic molding machines. And there are many types of injection molding machines and the parts will be big different.
