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: Process Improvements: Temperature gradients are virtually eliminated. Viscosity gradients are virtually eliminated. Composition gradients of colorant, chemical additives, fillers and regrind are virtually eliminated. Stagnant polymer wall-creep material is incorporated into the bulk polymer stream. Extrusion Applications Static Mixers are used in most extrusion applications including the following: Sheet Blown Film Foam sheet Profile extrusion Co-extrusion Pipe Extrusion Blow Molding Rod & Tubing Wire & Cable Coatings Fiber extrusion & monofilaments Benefits Reduction of color additives with comparable extrudate color density. Even thickness across the entire extrudate width. Streak-free product. Improved quality when using regrind material. Foam cell size and cell distribution uniformity. Improved surface quality Improved mechanical characteristics. Rapid color change-over SMB-R Static Mixer SMB-GXS Static Mixer Mixing of blue and white epoxy resin with the SMB-GXS Static Melt Blender. It improves the melt homogeneity by factor 5-6. 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. Mixing of blue and white epoxy resins. Empty tube (top)provides no mixing. Eight (8) mixing elements (bottom) provide an excellent mix quality in a short length. 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. 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.

Our agricultural stretch films (Blown Stretch Films) are PIB-based blown stretch films. Due to the special blown-film extrusion process they provide an even greater protection than cast stretch films. In agriculture, they predominately serve for the production of so-called silage bales which reliably protect the feed in small consumption units against weather and moisture for a long time and thus ensure that the feed retains its high quality. With their excellent adhesive characteristics our agricultural stretch film optimally seals the bale against the outside. The film has a thickness of 25µm and is available in the colours white, black, light green and dark green in the dimensions 750 x 1500 m² or 500 x 1800 m².

For automated processing we produce machine films in blown-film extrusion as well as cast processes. Film formulas with various amounts of maximum elasticity and resistance to penetration in various strengths and roll widths allow us to cover the entire spectrum of processing requirements for a stretch film. The type of film application depends on the respective load, the application purpose (dust protection or actual load security) and the machine utilised for the stretching. We are able to service all types of machines - from simple stretch machines operating only with braking power to the high performance stretch facilities with high rotational speed. To improve visual protection and protection from theft, we also produce our machine films in the standard colours black and white. Further colouration according to our colour reference catalogue are also possible. However, we also develop special colouration for our customers - so for example to incorporate a brand colour. Depending on the customer's request, we equip our machine films one-sided normal-adhesive / one-sided strong-adhesive or with a smooth side.

We produce our manual films in a variety of widths, thicknesses and quality levels from blown-extrusion films to cast stretch films. As well as the usual, still elastic hand rolls, we also offer pre-stretched manual films. To improve visual protection and protection from theft, all our manual films can be coated in the standard colours black and white. Further colouration according to our colour reference catalogue are also possible. However, we also continuously develop individual colourations in cooperation with our customers, so for example to incorporate the brand colour of the customer. Depending on the customer's request, we equip our manual films one-sided normal-adhesive / one-sided strong-adhesive or with a smooth side.
