Our Company History

Summary of PASSACO Activities

2011-2013

Optimizing the performance and lifespan of pelletizing disk scrapers – Gol Gohar Sirjan Mining and Industrial Company
In this project, with one year monitoring of the life of pelletizing scrapers of Gol Gohar Sirjan Company, their existing conditions were investigated and the scraper blade with ceramic material along with tungsten carbide coated screws was proposed.

2013-2014

Preparation and supply of cobalt-based superalloy electrode for use in coating.

2014-2015

Forming a research team for the industrial production of stud in the country at a low cost

Our Values

Commitment expertise innovation perseverance continuity

These factors motivate us to continue until the end
