Allied states that the Powder Metallurgy production method ensures a robust end product with strength and durability, making them particularly advantageous in situations prioritising reliability and resilience. This contributes to their extensive use across various mechanical systems and devices.

Machined or precision gears, being a subtractive process, are produced from cutting a gear shape via hobbing, grinding, or milling processes. These three methods enable exact control over gear size and tooth profiles, resulting in high accuracy. CNC machining enables the creation of gears with intricate designs and tight tolerances, meeting the demands of industries requiring precise gear engagement.

In its blog post, Allied Sinterings outlines the advantages and disadvantages of sintered gears compared to machined gears, based on:

  • Production costs
  • Production time
  • Precision
  • Strength
  • Quality
  • Scrap waste
  • Design flexibility
  • Self-lubrication capabilities
  • Ability to be impregnated with a variety of materials
  • Volume repeatability and overall cost
