Sintering process

Sintering is a manufacturing process in which a pulverized material is compacted in powder form at high temperature and pressure to form a solid part. This process is used to produce ceramic, metal, and other material parts.

The sintering process generally includes the following steps:

  1. Powder preparation: The material is reduced to a fine powder by grinding or atomization.
  2. Mixing and compaction: The powder is mixed with other additives and compacted by pressure to form a solid piece.
  3. Sintering: The compacted part is subjected to an elevated temperature in a furnace for a specified period of time. The sintering temperature is lower than the melting temperature of the material, but high enough that the powder particles fuse with each other and chemical bonds are formed.
  4. Post Treatment: After sintering, the part may require some post treatment, such as grinding, milling, or polishing, to improve its finish and dimensional accuracy.

Sintering has several advantages compared to other manufacturing processes. Some of these advantages are:

  1. Design Flexibility: Sintering enables the production of parts with complex shapes and custom sizes that can be difficult to manufacture using other manufacturing processes.
  2. High precision: Sintering produces parts with high dimensional accuracy and tight tolerances.
  3. High resistance and durability: The parts manufactured by sintering have a high resistance and durability due to the density and uniformity of the material structure.
  4. Cost: Sintering is an inexpensive process compared to other processes for manufacturing complex parts in small quantities.

In general, sintering is a versatile and efficient manufacturing process that offers a wide range of advantages for the production of high quality and precision parts.

This material contains interconnected pores impregnated with oil. The pre-lubricated bronze is separated from the material with which it rubs by the action of an oil film as long as there is movement. At the moment the movement stops, the oil is reabsorbed through the same pores that exist in the bronze.


This material is manufactured by the metal powder process. Bushings are the main application of this material. This material can be sold as a pre-lubricated bronze bar or a pre-lubricated bronze bushing.
