What Injection Molding Does
  • Injection molding produces plastic parts by injecting molten material into a mold, allowing complex shapes to be formed in a single step.
 
  • It also supports insert molding, where metal components such as threaded inserts, pins, or terminals are integrated directly into the plastic during molding — eliminating secondary assembly and improving part strength and reliability.
  • This makes it suitable for parts that require consistent dimensions, repeatability, and clean surface finishes across large quantities.
