Insufficient surface quality, long cooling times, uneven thickness tolerances or other quality problems often limit maximum production output. Promix melt blenders eliminate these limitations sustainably and lead to significant cost savings. Would you like to optimize your extrusion process? Improved melt homogeneity and a more uniform melt temperature create tighter thickness tolerances and better surface quality. And quite often, it can also increase production throughput. Promix offers you highly effective static mixers and melt blenders at low investment costs. They are supplied ready for installation, including heater bands and holes for pressure and temperature sensors. The melt blenders are usually installed downstream of the screen changer & gear pump, and upstream of the die. The very short installation length allows easy retrofitting in existing extrusion lines.

Promix specializes in demanding cooling and heat exchanger tasks such as cooling and heating of viscous or decomposition-sensitive media / plastic melts. The Promix P1 heat exchanger is the unique combination of a very efficient static mixer and a powerful cooler. The novel patented technology opens up completely new process engineering possibilities in the cooling and heating of plastic melts and other viscous fluids. The simultaneous mixing and cooling processes in the P1 allow for very efficient cooling and heating without the formation of deposits or the risk of product decomposition. Advantages Promix P1 heat exchanger Very efficient cooling of polymer melts close to the solidification point Precise temperature control and uniform temperature distribution at the outlet Very robust construction Extremely gentle cooling and heating of residence time critical fluids Unique self-cleaning behavior Reliably scalable from laboratory test to production scale Test options

Fat melting systems The KASAG fat melting system are compact systems for melting fat blocks from palm kernel fat, palm oil fat, coconut fat and concentrated butter. The liquid grease thereby gained is kept in the collecting tray at a specified temperature to be used in the respective production process. Size and design are determined by KASAG according to the requirements of the customer. Fat oil station KASAG fat oil station is an extension of the fat melter and is used to mix the ingredients into the liquid fat. The plants are installed on a base frame with levelling feet. All built components are ready for connection. The hot-water treatment and regulation is conducted via a tempering unit or connection to an existing hot-water network.

Mixing nozzles and static mixers from Promix ensure excellent melt homogeneity and efficiently prevent color streaks or flow lines. Quality problems in injection molding are often solved by modifying the process parameters. Masterbatch concentration and back pressure must be increased, which makes production costs more expensive. This does not have to be the case! Mixing Nozzles from Promix ensure excellent melt homogeneity. Color streaks or irregularly distributed additives in the component are a thing of the past. The ready-to-connect mixing nozzle is installed on the injection molding machine replacing the standard nozzle. Contact us for a mixing nozzle to test.

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.
