StaMixCo manufacturers all three commercially proven static mixer designs used for high viscous melt flow mixing of polymers in extrusion service. As with most process equipment, each static mixer design has specific advantages and disadvantages that make it more or less suitable for a specific application and installation. Each type of motionless mixer is discussed below: |

The SMB-R static mixer for extrusion service (licensee of Bayer AG, Leverkusen, Germany) contains eight (8) very efficient motionless mixing elements that homogenize the polymer melt as it enters the extruder die. The SMB-R mixing elements are virtually indestructible due to their monolithic cast construction where the mixing bars are jointed to each other and to the ring wall via a single molten metal pour. |

SMB-GX Static Mixer Melt Blender
Figure #9 |
The SMB-GX motionless mixer is a design that has been used in melt flow mixing extrusion service for over 25 years. Since the SMB-GX is manufactured from metal plates that are welded together, virtually any custom static mixer plate thickness, material and diameter can be fabricated to meet process and installation requirements. |

The SMB-H Helical static mixer design pioneered the static mixing industry and has been used as a viscous static mixer on extruders for over 37 years. |
StaMixCo manufactures SMB-H static mixers by advanced proprietary manufacturing technique where the entire unit is machined from a solid rod of bar stock material without welding. This machining process allows for custom static mixer fabrication in virtually any L/D twist, in very small sizes, with very high strength, straight and true dimensioning and with a RMS 12 mirror polish surface finish which is a much improved surface finish as compared to the traditional 32 RMS finish for the twisted and welded design.
