Plastic injection molding machine

Approach

Introduction

A plastic injection molding machine is a machine used in the industry to manufacture plastic parts through the injection molding process. This is one of the most common methods for mass-producing plastic components, such as automotive parts, toys, household appliances, packaging, and more. How does a plastic injection molding machine work?

    The basic process involves the following steps:

                
  • Plastic melting:
    • 
            Plastic, in the form of granules or pellets, is fed into a heated barrel. Inside the barrel, a rotating screw or plunger melts the material through heat and pressure.

            
  • Injection:
    • 
            Once the plastic is melted, the screw or plunger pushes it forward with high pressure, injecting it into a closed mold.

            
  • Molding:
    • 
            The melted plastic completely fills the mold cavity, taking the desired shape. The mold is cooled (often through an internal cooling system), solidifying the plastic.

            
  • Ejection:
    • 
            Once the part solidifies, the mold opens, and an ejection system removes the finished part.

Main ideas

The command "git add." was used to add all the changes saved in visual studio, then "git status" to know if all the changes were saved, then we tried to upload the files with "git commit -m "title"", but since there was no registered user or email, they had to register them with "git config –global user.email "your@example.com"" and "git config –global user.name "your name""

    The basic process involves the following steps:

                
  • Horizontal plasticizing cylinder
    • 
This makes it easier to use a motor with a gearbox.
            
            
  • Different nozzle sizes
    • 
The possibility of having different nozzles for various functions is being considered.  

            
  • Auger screw
    • 
Although there is a method to build this injector without the auger screw (using a metal cylinder and lever to compress the material), I prefer to implement the screw in this case.  

            
  • Motor with gearbox
    • 
While it’s possible to use the motor without the gearbox, including it seems like a better option.  

            
  • Adjustable temperature
    • 
Modules will be added to regulate the resistance temperature, allowing the use of different types of plastics.  

            
  • Adjustable motor speed
    • 
By including speed control for the motor, better results can be achieved in the generated shapes.
