SMB-GXS Static Mixer Melt Blender

The New STAMIXCO Extrusion Melt Blender SMB-GXS* consists of four (4) to eight (8) very efficient static mixing elements with integrated longitudinal bars. This design offers an improved strength with an open structure (no ring). The SMB-GXS mixing elements are extremely resistant due to their monolithic cast construction where the mixing elements are obtained via a single molten metal pour. They are made of heat treated high strength 17-4 PH stainless steel.

SMB-R Static Mixer

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 considered as high performance design where they create a very high degree of mixing in a short length.

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

The SMB-GX motionless mixer is a design that has been used in melt flow mixing extrusion service for over 25 years.
The SMB-GX mixing elements are considered as high performance design where they create homogeneous mix in a short length. It has the same fundamental X-Grid crossing-bar structure as the StaMixCo SMB-R static mixer (Figure #8), but without the support ring around the mixing blade structure which gives the SMB-R its remarkable strength.

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.

SMB-H Static Mixer Melt Blender

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.
The Helical design is considered a low mixing performance-long length-low pressure drop motionless mixer as compared to the later developments of high performance static mixers such as the SMB-R and SMB-GX which have become the technology standards in the industry.
