Pavlograd Mechanical Plant (PMZ) was established in December of 1963 as a specialized production facility of the Plant #586 (now Yuzhmash Production Assn.).  quotes 1931 as establishment date. Perhaps, that relates to a previous facility, which existed at that place and was used as a basis for PMZ. (According to some sources, it was initially a workshop associated with an artillery test range.)
PMZ is a dedicated factory for assembly, perfection and production of solid-fueled rocket engines and missiles. By 1975 PMZ became the largest solid-rocket factory within the Ministry of General Machine Building of USSR. PMZ made fuel tanks for booster rockets and plastic ICBM rocket motor casings; parts, components, and assemblies for aerospace systems manufacturing.
PMZ remains a constituent part of Yuzhmash Production Assn.
EMPLOYMENT: approximately 6,800 
KEY TECHNOLOGIES/EQUIPMENT EMPLOYED: Machining; electric and gas welding; parts and components manufacturing from composite materials; electroplating; titanium casting and assembly.
The Plant possesses one of the greatest rocket engines test stand and the unique facility for drop tests of the missiles with the "cold" type of launch.
PMZ intends to produce parts and components made from composite materials for aircraft; and electric household devices.
CIVIL PRODUCTS include casings for wind generators; titanium bicycle frames; titanium church bells; household food processors; electric buses; trolleys; excavating machines; wind turbine electric generators; electric and household machinery.
