Injection Molding

What is Injection Molding?

Injection molding is a manufacturing process used to produce parts by injecting molten material into a mold. This process is commonly used for producing plastic parts, but it can also be used with metals, glass, and other materials. Injection molding offers high efficiency, accuracy, and versatility in creating complex shapes with consistent quality.

What is the process of Injection Molding?

Injection Molding Process

  1. Clamping: The mold, consisting of two halves (the stationary side and the movable side), is securely closed by the clamping unit of the injection molding machine.
  2. Injection: Molten material, typically plastic pellets, is fed into the injection molding machine's hopper. The material is then heated to a specified temperature and injected into the mold cavity under high pressure through a nozzle and runner system.
  3. Pack and Hold: After the mold cavity is filled with molten material, the machine applies additional pressure to pack the material tightly and compensate for shrinkage as it cools. This step is known as the pack and hold phase.
  4. Cooling: The molten material inside the mold cavity is allowed to cool and solidify. Cooling can be accelerated using water channels within the mold or other cooling methods.
  5. Opening: Once the material has solidified, the clamping unit of the injection molding machine opens the mold, separating the two halves.
  6. Ejection: The finished part is ejected from the mold cavity by ejector pins or other mechanisms. It is then collected for further processing or inspection.
  7. Closing: The mold halves are closed again, and the injection molding machine is ready for the next cycle.

This process repeats continuously, allowing for high-volume production of plastic parts with precision and consistency.
