Dosing & Blending
Traditional Options for Processors
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
Dosing by Volume
• The Most Common Methods :
• ‘Pocketed Wheel’ Metering• ‘Screw’ Metering

What about Regrind ?
Proportional Valve
Closed Loop Systems
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
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
Gravimetric Blending
Introduction to Maguire Technology
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

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 %

Client Cost Analysis
Increased performance at a lower cost
Cost Savings
• Why specify a Maguire?
Maguire now is proven as the market leader due to features and benefits at an affordable price.
• How can Maguire help with Materials?Maguire gives the manufacturer the ability to blend with ease and confidence at a fraction of the cost of utilising a compounded material.
Cost Saving Analysis• Time
5 days, 20 hr/day, x 50 weeks = 5000 hr/yr• Materials
200 kg/hr = 1,000,000 kg consumption• Masterbatch addition
2.0 % masterbatch used = 20,000 Kg/yr• Price
masterbatch price US$16/Kg = US$320,000 per year
Cost Saving Analysis
• Maguire In our experience with volumetric systems we estimate that processors while aiming to dose at 2.0% actually dose between 1.9% to 2.6%; on this basis 20% fluctuation is not unusual
• Financial saving20% of US$320,000 masterbatch =US$ 64,000 in masterbatch saved per annum
Compound v Natural
• The savings for companies using compounds will again be high.
• Direct material costs savings can range from 5% to 30%.
• Indirect costs for the manufacturer include– Warehouse & Stocking– Distribution costs– Re Drying– Materials degradation in regrind
