Metal Injection Molding

Design Potential and Practicality

Recently, products such as information technology, electronic and medical device have been downsizing while increasing in complexity and tolerances. In response to this trend Castem started developing MIM methods and technology in 1991. We now manufacture many components which can only be manufactured utilizing MIM. We also have committed to the most technologically advanced quality control and production equipment to ensure we can provide the most economical and quality MIM products to our clients.

Process Flow

Let us show you how we can provide excellent quality while reducing costs of you current machined component regardless of volume.

Comparing Strengths

Castems MIM production is superior to conventional machining for many reasons. The graphic below compares the strength of density – Metal Injection density is more than 95% and the mechanical strength is high with independent spherical pores. Whereas traditional sintering is 88% and the mechanical strength is inferior with many pores existing in the grain boundary.

Conventional Machining

  • Design limitations
  • Labor intensive
  • Costly process
  • Significant material waste
  • Low production volumes
  • Multiple set up requires
  • Difficulty to machine internal treads
  • Identification separate step

Metal Injection Molding

  • Ideal for complex shapes
  • Highly automated process
  • Lower cost
  • Minimal material waste
  • Easily adapted to low or high production levels
  • Single tool
  • Exterior and interior treads
  • Identification can be moulded in
