| Extrusion |
|
|
Sulzer Melt Blenders are fitted just before the extrusion die, where the mixer equalizes the variations in the laminar flow layers of the polymer melt. This ensures that the melt entering the die is of the highest quality and allows the extrusion process to be optimised in order to achieve the highest quality product possible.

| Foaming |
|
|
Foams modify material properties, improve product quality and yield a number of benefits to processors and consumers. When it comes to foaming polymers and cellular applications, the equipment plays a key role since foaming processes are very sensitive.

| Foaming with static mixers in Extrusion |
|
|
Foamed polymers are widely known in extrusion of insulation sheets and packaging applications. Bubble size and temperature distribution are key figures in this process. Therefore Sulzer SMB-R and SMB-H mixers play a major role in these applications due to low shear forces and high homogeneity within the mixer.
The mixer can be installed before and after the polymer cooling unit.

| Injection Molding |
|
|
In injection molding, processing problems, such as the formation of colour streaks, are often solved by modifying the machine parameters. In the production of coloured products, striation problems, which cannot be solved through modifying machine conditions, are often overcome simply by increasing the master batch concentration.

| Optifoam™ for Liquid Silicone Rubber (LSR) |
|
|
Optifoam is a retrofit solution for LSR foam injection molding relying upon two modules. A physical blowing agent is added into the components A and B using proprietary sinter metal technology. Static mixers secure a homogenous solution and optimum results in product properties.
