1 Nordson Europe Industrial Coating Systems 3 rd Generation Powder Coating Equipment

2 Founded in 1954 Worldwide presence in 57 countries 4000 employees worldwide + 25,000 Nordson customers 2007 sales performance: $993 million Sales outside the United States: 67 percent of 2006 sales Corporate homepage The world's leading manufacturer of systems that apply adhesives, sealants and coatings during manufacturing operations.

3 Headquarters in Cleveland, Ohio, USA Direct operations and sales offices in 30 countries with more than 100 distributor organizations

4 Industrial Coatings The company is structured into three major business segments : Adhesive DispensingAdvanced Technology

5 Coating and finishing systems Since the 1970’s powder coating application technology has……… Industrial Coating Systems 1st Generation Low voltage cable fed guns (IPS) Improved booth technology (focus) Tribo High voltage cable fed guns Application focused High output – low transfer efficiency 2nd Generation

6 Consistent, constant and reliable results If you were to design the perfect powder coating system ? Third Generation Technology Industrial Coating Systems Clean environment Place powder only where its needed Reduced waste Control and manage the production Reduced labour Reduce operator acceptance and skill level Quick colour change

7 The Heart / HDLV Pump Nordson examined the three disciplines of powder coating: What is ‘third generation’ coating technology Powder Transport Powder Circulation Precision Dispensing To improve each area we developed our ‘dense phase’ product family named Prodigy ® HDLV ®

8 The Heart / HDLV Pump Powder delivery hose has a high concentration of powder, very little air. Traditional venturi pumps use hi-velocity air – HDLV pumps meter powder to the gun using less air to propel. HDLV is 4 times slower – softer spray. What is ‘Dense Phase’ Equipment ? HDLV = High Density powder, Low Velocity air Prodigy ® HDLV ® Technology Delivery hose cross section Dense Phase Hose Venturi Pump Hose

9 The Heart / HDLV Pump What is ‘Dense Phase’ Equipment ? Prodigy ® HDLV ® Technology Delivery hose cross section

10 What Does It Do For The User ? Prodigy ® HDLV ® Technology Provides process control Less overspray Higher transfer efficiency Lower velocity powder = higher useful electrostatic force Paints faraday areas and corners easier Higher powder output with better charging

11 The Heart / HDLV Pump Prodigy ® HDLV ® Technology At the centre of dense phase technology is the HDLV (High Density Low Velocity) pump. It resembles a human heart in that it consists of two side by side pumps each with an upper and lower chamber working together to provide precise, carefully synchronized powder transport.

12 How Does It Work ? Prodigy ® HDLV ® Powder Transport

13 Dense Phase Pump Flow rate controlled by cycle rate & suction duration Very little air goes out to the gun 0.5 to 1.2 scfm of conveyance air Use 6mm ID powder tubing The old and the new Traditional Venturi Pumps vs Dense Phase Pumps Venturi Pump Flow rate controlled by combination of Flow + Atomizing air flow rates Lots of air goes out to the gun Use 11mm or 12.5mm ID powder hose

14 Dosing air Venturi pumps are non-linear in output Traditional Venturi Pumps vs Dense Phase Pumps

15 Dense phase pumps achieve linear output Traditional Venturi Pumps vs Dense Phase Pumps

16 Lack of wear components means consistency over time Traditional Venturi Pumps vs Dense Phase Pumps

17 Reduced total air consumption compared to venturi pumps Traditional Venturi Pumps vs Dense Phase Pumps

18 Prodigy ® HDLV ® Powder Transport Self cleaning / colour changing Constant powder output over time 30 second colour change High volume – low air consumption 6mm ID powder hose Dense Phase Pump Without Moving Parts

19 Prodigy ® HDLV ® Precision Dispensing Unique profile prevents powder build up on the gun New gun to spray dense phase Automatic gun with straight through powder path, optimised for dense phase dispensing and quick colour change

20 Prodigy ® HDLV ® Precision Dispensing Voltage multiplier positioned at the back of the gun – so it operates outside of the booth, reducing gun flex and grounding issues New gun to spray dense phase

21 Prodigy ® HDLV ® Precision Dispensing Advanced transfer efficiency even improves speed of coating ! New gun to spray dense phase

22 Coating parameters stored in application controller Digital control and storage of : Voltage Current Air Flow Gun Movers Prodigy ® HDLV ® Precision Dispensing

23 Coating parameters stored in iControl 1 place to focus on… The Central Controller Copy / paste function for settings Security access levels Simple graphics or icons % Adjust button Prodigy ® HDLV ® Precision Dispensing

24 High capacity pump Prodigy ® HDLV ® Powder Circulation Simple pneumatic control for ease of operation Less compressed air used to propel the powder results in more efficient recycling  Improved sieve efficiency and throughput Automatically purge-able Less wear, no venturi throats to replace

25 Recycling Colour change Recycle more efficiently with reduced air and more powder Prodigy ® HDLV ® Powder Circulation Small compact surge hopper Designed for automatic fast color change without disassembly Small flexible tubing - 12mm ID

26 High transfer efficiency of Prodigy spraying in a ColorMax 3 booth Advanced Booth Design Clean working environment Less to clean; faster colour change The Old Way The New Way

27 Third Generation Coating Equipment Prodigy ® HDLV ® Technology 3 Steps To Process Control  Transport process control is achieved by eliminating venturi wear from the equation and ensuring that air inputs to the pump are monitored and driven by a closed loop control system, dynamically compensating for fluctuations in factory air supply

28 Third Generation Coating Equipment Prodigy ® HDLV ® Technology 3 Steps To Process Control  Dispensing process control is achieved by conserving all application parameters in the control system, and by spraying through a soft spray gun suited to dense phase applications. This ensures the same results are achieved day after day

29 Third Generation Coating Equipment Prodigy ® HDLV ® Technology 3 Steps To Process Control  Recycle process control is achieved by reduced compressed air used to propel the powder, producing more efficient recycling, sieving and bulk feeding

30 Process Improvement Prodigy ® HDLV ® Technology Fig.1 shows a powder coating line running without Prodigy technology, showing the film thickness across the product. Point 1 is the minimum required film thickness

31 Process Improvement Prodigy ® HDLV ® Technology When dense phase coating is compared process control can be clearly displayed

32 Process Improvement Prodigy ® HDLV ® Technology Once process control is accomplished, improvement is achievable by using the control system and ‘digital’ nature of the technology to % adjust the gun outputs (linear output)

33 Dense Phase Equipment summary Process control and improvement Better coating penetration Consistent powder flow rate over time Less air consumption Faster color change Higher quality color change Prodigy ® HDLV ® Technology
