A sintering press machine is a type of industrial press used to compact powdered materials (often metal or ceramic powders) into a solid form and then heat them just below their melting point. This process is called sintering, and it allows particles to bond together without fully melting — creating dense, strong, and precisely-shaped parts.
How Does It Work?
The sintering process involves two main steps:
-
Powder Compaction:
A die cavity is filled with powdered material, and high pressure is applied using the press. This forms what’s known as a “green compact”. -
Sintering:
The compact is then heated in a controlled atmosphere furnace at a temperature below the melting point of the material. The heat fuses the particles together, increasing the part’s strength and integrity.
Some advanced sintering press machines integrate hot pressing, where heat and pressure are applied simultaneously, improving the mechanical properties of the final product.
