What is Sintered metal parts:
Sintered metal parts are made using a powder metallurgy technique called sintering. In this method, metal powder is compressed into a precise shape, and then heat is used to attach the metal particles inside the created item, enabling it to maintain its new shape. Sintering can be used to produce a wide range of metal part types and is compatible with many different metals and alloys.

What is the sintering process:
Sintering process is to prepare iron ore powder, flux, fuel and substitutes according to the requirements of blast furnace smelting, according to a certain proportion of batching, mixing, adding water lubrication. Regranulation, distribution ignition, with the help of the fan, so that under the action of a certain high temperature, the surface of some iron ore powder softening and melting, produce a certain liquid phase, and other final melting ore particles, after cooling, the liquid phase will stick the mineral powder particles into blocks this process is sintering process.
The basic sintering process
powder pressing → charging (preparation before loading and sintering) → sintering (preheating, heat preservation and cooling) → coming out → sintered body
