Manufacturing Process

The manufacturing process of sintered parts includes a few basic stages of manufacture. It also includes some complementary stages that change, depending on the technical and functional characteristics of the product.


The first stage consists in taking iron powder in different qualities according to DIN-ISO before mixed or alloyed with other components like Cu + Lubricant, C, Cr, Mo, P, C, or Ni.


On this stage, different components are mixed to obtain the final alloy with a precise and homogeneous form.


Pressing is the operation that gives form to the part. It gives high pressure in special tools of high precision set on the press, which presses the powder. It produces the union of metallic particles and then it obtains a·minimum of mechanical resistance that allows to be manipulated.


In this stage the material is placed in special ovens with a temperature lower than the point of merger of the material, normally 1.120 degrees Celsius / 1.150 degrees Celsius, under a strictly controlled purity atmosphere, which produces a weld of particles for metallic diffusion. These pieces obtained in this stage are similar to steel


A complementary stage of sintering is to calibrate. It is realized by special presses and tools which make a better submit to the parts to improve them in a geometric precision and superficial state for mechanical deformation of the part against the tool. It makes a heavy and hard material.


After these operations in each part in which a strict quality control is realized, the company will have the final product ready to sent it to the customer.
