Injection Molding Process

As the name suggests in this molten material (thermoplastic material mostly) is use for injection material to get the desired product

Working Injection Molding Process:

• In this pellet is feed first which are compressed by the spiral plunger to reduce the air gap and later onwards they heated up to a stage where they will convert it into a molten state.
• Then the spiral plunger rotate and move forward to feed the molten thermoplastic into the die cavity by the nozzle to get the desired shape product
• When spiral plunger moves backward check ring and thrust ring stop the backward flow of the molten thermoplastic 

Advantages of Injection Molding Process:

• Complex shape can be made by this process
• Good production capacity
• Good Dimensional Accuracy

Disadvantage of Injection Molding Process:

• High Initial Cost
• High Tool cost
• Not very small and too big size can be used for this process
• Experties need for the design for die use in injection molding process to prevent unnecessary leakage of the material

Applications of Injection Molding Process:

• Toys , product covers ,chair and much more
