  3. Introduction to Maguire • 22 years manufacturing blending equipment for plastics • 1989 : ‘Weigh Scale Blender’ launched • 1993 : Becomes the World’s best selling gravimetric blender • Sales are close to 3,000 per annum • More than 80 WSB models • Wide range of application & throughputs • Market Leader

  4. Maguire WSB Sales per Annum

  5. Maguire 97 & 98 World Sales

  6. Maguire World Sales & Support

  7.  Dosing & Blending Traditional Options for Processors

  8. The Dosing Choices • In general, a processor who is going to switch from pre compounded materials to raw materials will have 3 options for mixing. • Proportional Valve + Doser • Volumetric Blending • Gravimetric Blending

  9. Dosing by Volume • The Most Common Methods : • ‘Pocketed Wheel’ Metering • ‘Screw’ Metering

  10. Pocketed Wheel Metering

  11. Screw Metering

  12. Volumetric Dosing Variations Set % Required %

  13. What about Regrind ?

  14. Proportional Valve

  15. Closed Loop Systems

  16. Problems : Volumetric Dosing • Time consuming manual calibration • Skilled personnel required for setting • Formulas and process data required for calibration • Assumes consistent bulk density of materials

  17. Blending Requirements • Minimise labour • Minimise involvement of skilled personnel • Accurately control material usage • Cut waste and scrap • Less down time; More production time • Repeatability of product • Peace of mind

  18.  Gravimetric Blending Introduction to Maguire Technology

  19. Why Gravimetric ? • Technological affordability • Consistent accuracy • Automatically adjusts for variations in bulk density • Calibration is an automatic function • Setup in minutes - not hours • Measures by Weight - not Volume • Eliminates errors calculation

  27. Mixer Clean-out

  28. Maguire Auger Feeder

  29. Accuracy • Every batch followed by error correction routine • Accuracy rises by restricting a slide gate or auger feeder • Immune to vibration 1% Setting = Typical accuracy of + / - 0.05 %

  31. Maguire: Further Features • Audible & Visible Alarms • Lock Out Settings • Recipe Storage • Password Access • Regrind Control • Off Line Batch Operation

  32. Off-line Batch Blending

  33. Maguire: Advantages • Only Gravimetric to mount directly on throat • This system will never drop an incomplete batch • Automatically adjusts additive quantities as regrind levels fluctuate • Automatic calibration and correction • Extremely user friendly

  34. Maguire: Advantages • Ease of maintenance, few mechanical parts • Efficient mixing with no ‘dead spots’ • Highly accurate • Excellent for ISO 9000 Standards • Proven with over 11,000 units • Quick Clean-out

  35.  New Developments New additions to the range

  36. Maguire Micro Pulse • Patented new technology • Revolutionary design • Micro Pulseallows the processor to dose a pellet at a time • Micro Pulse can replace conventional Auger feeders bringing cost and maintenance down • This new technology is immediately available only with Maguire

  37. Maguire Micro Blender • Maguire has launched a new innovative Micro Blender to its already comprehensive range of 80 blenders : • Throughput of approximately 30 Kg/hr • New patented Micro Pulse technology • Immune to Shock & Vibration • New Pneumatic Mixer process • Fully removable materials hoppers • Weight of less than 29Kg • Footprint of 15cm x 15cm

  40.  Data Retrieval Monitoring & Recording blend data

  41. Standard Data Retrieval • Individual material weights used • Total batch weights dispensed • Set percentages • Achieved percentages • Works order & operator tractability • Dates & times • Blender ID number

  42. WSB Printout

  43. Total Blend Data Benefits - • Sales tool to develop client confidence • Planning of material costs • Historical information • Quality control • Job costing • ISO 9000

  44. ‘MLAN’ PC Communications • 2 way communication for Maguire blenders • Maintain material database • Set blends from a remote location • Monitor all blends from one terminal • Produces Reports from retrieved Data • Graphical data interpretation • Download data to Disk or Hard copy
