Know-How
Our Process
We use our experience of more than 30 years in the field of petrochemicals and our network of experts, to create new powders.
And this is procedure of our development work:
And this is procedure of our development work:
The formulation
The compounding
The grinding
The powder
The formulation
The material contains several polymers and additives. It is important that each component has a similar melting point. To find the right formulation we use the DSC analysis and the Kofler hot stage.
The compounding
In a twin screw compounding machine the components are melted together and granules are produced.
The grinding
We use special mills so that the grinding process does not influence the material properties. The shape of the particle is important and must not be too spherical or too square.
The powder
To analyze the size and shape of the powder, we use scanning microscopy. The powder must have a good flowability to ensure a homogeneous creation of layers during the laser sinter process.
