Title: John J Fulmer: Innovator in Powder Metallurgy

Introduction

John J Fulmer is a notable inventor based in Mt. Laurel, NJ (US). He has made significant contributions to the field of powder metallurgy, particularly through his innovative methods for preparing sintered components. His work has implications for various industries that utilize iron-containing and alloy steel powders.

Latest Patents

Fulmer holds a patent for an "Optimized double press-double sinter powder metallurgy method." This patent outlines methods for preparing sintered components from iron-containing and alloy steel powder. The process involves compacting a powder mixture in a die set at a pressure of at least about 25 tsi to produce a green compact. This compact is then presintered at a temperature of about 1100°F to 1600°F (593°C to 870°C) for at least about 5 minutes to create a presintered preform. The presintered preform is subsequently compacted at a pressure of at least about 25 tsi to produce a double-pressed presintered preform, which is sintered at a temperature of at least about 1000°C for at least about 5 minutes. This results in a sintered component that exhibits improved transverse rupture strength and higher density.
