The SinterFire process is both very simple but very complicated. Good designs, efficient manufacturing operations and control of the processes are a must. Metal composite materials are blended and compressed under tonnage and heat treated to a temperature that induces a metallurgical change. The heat treatment process is done in a controlled inert atmosphere using specialized equipment with strict and redundant controls.
The variability of materials and processes are endless and a very small change to any of the elements will effect a very large change in ultimate performance. A quality system using Statistical Process Control is in place to document the manufacturing processes and critical characteristics of frangible bullets.
