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
