Service We Offer


PKPM ADVISORY GROUP (PKPM) was founded by Rocco Petrilli (PRIMA BUSINESS SPECIALISTS LLC,) and Dr. Michael Krehl (MTSG Consulting,), as a compliment to their individual business specialties firms, to provide professional, commercial and technical consultation to the global powder metal (PM) industry. Both Krehl and Petrilli enjoyed long-term management careers in the PM global marketplace and are experienced in all aspects of the PM business.

Powder metallurgy (PM) is a long-standing disruptive technology that has significantly impacted the metals manufacturing landscape over the last half century. As a prime example, in the period from 1988 to 2003, the average weight of components in a North American built car/truck grew from 8 to 55 lbs. (3.6 to 25 kg). Advances in powder and net shape processing technology now make the manufacture of key performance components like connecting rods, main bearing caps, high performance transmission gears cost effective, reliable and routine. Processing advances such as MIM (metal injection molding), soft magnetics for automotive electrification and 3D additive manufacturing continue the proliferation of this technology and promise to secure its future.

PKPM services its clients in the areas of strategy development/execution, operations, sales, marketing and business development, R&D and talent acquisition and retention. A focused specialty of PKPM is advisory services involves mergers and acquisitions including but not limited to valuation of acquisition targets, planning and execution of due diligence processes and integration of the newly acquired enterprise. 



The PM industry, like many global manufacturing businesses, is challenged with the shortage of WISDOMTM or the combined knowledge and experience required to quickly solve complex problems. Additionally, PM has always suffered from the absence of any real university-based curriculum that provides a ready source for its new talent. This absence has created a perpetual recycle of top industry human capacity to satisfy (temporarily) these growing company needs.

Given the retirement of many of the industry pioneers, the availability of true business and technology specialists for consultation has also diminished. PKPM serves the PM industry with its unmatched WISDOMTM and the ability to lead, solve or compliment any PM related endeavor.
