rapid plastics - injection molding\'s basics
After heating, inject the fluid plastic into the mold opposite the shape of the desired product at high pressure.
Injection molding is widely used in the manufacture of various parts, from the smallest parts to the entire body panel of the car.
The process of injection molding can be described in four simple steps.
These include plasticization, injection, cooling and injection.
Each of these steps is different from the other and it takes the right procedure to complete the whole process successfully.
These steps can be discussed as follows: plasticization includes the conversion of the polymer material from the normal form of hard particles at room temperature, betting on the required liquid at the correct melting temperature.
Injection This is the stage in which this melt is introduced into the mold to fully fill the cavity or cavity.
Cooling is the act of removing heat from the melt and converting it from the liquid consistency back to the original rigid state.
The pop-up stage is the final stage of taking out the cooled molded part from the mold cavity.
The ball or powder materials used in the injection molding machine are mainly: o ethylene multi-styrene multi-carbonated multi-propylene-oAcrylonitrile-Butadiene-Styrene (ABS)
The use of these basic steps in sequence or in a loop is an injection molding process to obtain or manufacture parts.
The cycle time typically ranges from 10 to 100 seconds and is controlled by the cooling time of the melted plastic.
The melted plastic comes from the hard plastic particles injected into the hopper-Forming Machine.
The particles or plastic powder are melted inside the machine and then forced into the mold by heating the long spiral inside the cylinder through the nozzle.
It is the most common production method, some common items including bottle caps and outdoor furniture.
Injection molding usually has tolerances.
Plastic molding applications are in the medical field, such as blood analyzer equipment, heart pump components, plastic surgery equipment and components for custom knee brackets.
It is used for mechanical levers, gears, washers and switches in automotive engineering.
It is also used for aerospace, automotive, avionics and computer components.
