About HMA Group Divisions
Formed in 1966, Halley & Mellowes represents an impressive list of internationally respected companies and manufactures under licence to a number of these companies. We also manufacture a range of products and equipment developed and designed by our own engineers. In 1990 an employee owner group was formed and acquired 50% of the company from co-founder Mike Mellowes. These shareholders span a diverse section of the company and underwrite the efficient function of the Halley & Mellowes Group.
The Halley & Mellowes Group of Companies (The HMA Group) manufactures, services and sells a wide range of capital plant equipment to a diverse range of industries. This includes the mining sector, processing, material handling, power generation and oil and gas refineries.
