Process Steps<\/strong><\/h2>\n\n\n\n
    \n
  1. Mixing<\/strong> – Fine metal powder is homogenously blended with thermoplastic binders<\/li>\n\n\n\n
  2. Injection molding<\/strong> – Feedstock compounds into precision tool cavities through molding machines<\/li>\n\n\n\n
  3. Debinding<\/strong> – Binder removal via thermal or chemical solvent techniques<\/li>\n\n\n\n
  4. Sintering<\/strong> – Brown parts densified into final components reaching 95-99% solid metal densities<\/li>\n\n\n\n
  5. Post processing<\/strong> – Secondary machining, joining or surface enhancement<\/li>\n<\/ol>\n\n\n\n

    Correct sequencing and optimized parameters are critical to cost-effectively maximizing mechanical properties.<\/p>\n\n\n\n
