 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

Pocketed Wheel Metering

Screw Metering

Volumetric Dosing Variations Set % Required %

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

 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 saving 20% 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

Compound v Natural US$ / 1000Kg
