Metals Processing

Aerospace Coatings

Fine grain powders, new alloys and advanced thermal technology enable ever wider application of sintered metal parts throughout the industry.

Approximately 20 pounds of powdered metal are currently used in the manufacture of one automobile, and usage is rising yearly. The high density of sintered powders makes them ideal for components such as gears and other advanced applications.

From mesh belt conveyor furnaces for brazing, annealing, and powdered metal sintering, to high-production, 1400°C roller hearth furnaces for refractory metals processing, Harper technology continually evolves to match the needs of the metals processing industry. Harper’s mesh belt design is so highly regarded that its features have been widely incorporated worldwide.

Harper elevator-retort furnace systems provide superior temperature uniformity and ultra-pure atmosphere to process critical engine components with minimal gas consumption. Harper gantry furnaces optimize production while enabling the processing of the most delicate fixture loads. Whether you are engaged in a traditional or emerging application, you can look to Harper for the precise thermal technology and equipment you need.
