HOT MELT ADHESIVE OPTIMIZATION

1. HOT MELT ADHESIVE OPTIMIZATION How to optimize ADHESIVE consumption

2. Is your company using more hot melt adhesive than they need to? ..... …..Let’s look at some issues common to adhesive application. A B About Ellsworth | Ask The Glue Doctor | Engineering Sales Reps | www.ellsworth.com | 1-800-888-0698

3. If the fibre tear of A is strong enough, why use B ? How much extra adhesive is used by bead B ? B A About Ellsworth | Ask The Glue Doctor | Engineering Sales Reps | www.ellsworth.com | 1-800-888-0698

4. Reality is close to 4X If we start with the original glue bead… … and then half the bead width, how much do we save ? ½ the original bead About Ellsworth | Ask The Glue Doctor | Engineering Sales Reps | www.ellsworth.com | 1-800-888-0698

5. Why is it common to use too much adhesive ? Often because we have blocked nozzles from system CHAR. So … We increase the size of nozzles 1 = About Ellsworth | Ask The Glue Doctor | Engineering Sales Reps | www.ellsworth.com | 1-800-888-0698

6. Or ... Because we increase the pump pressure 2 Pump visual of the glue bead % increase pressure with same nozzle size in adhesive consumption 1.5 bar = = 0.45 g/m 2.0 bar = = 1.0 g/m = 122 % 2.5 bar = = 1.4 g/m = 211 % 3.0 bar = = 2.4 g/m = 433 % 3.5 bar = = 3.2 g/m = 611 % NOTE: 1 Bar = 14.5psi About Ellsworth | Ask The Glue Doctor | Engineering Sales Reps | www.ellsworth.com | 1-800-888-0698

12. As we move up the value / performance grid, what benefits do we achieve?... 1 350oF Exposure Test Adhesives that are more viscosity stable and resist charring. Both avoid having to increase nozzle size and change system pressure. Image provided by H.B.

13. As we move up the value / performance grid, what benefits do we achieve?... 2 Adhesives that cut off cleanly rather than produce a “tailing” effect. Clean cut-off means less clean up, less downtime and less adhesive consumed. Image provided by H.B.

16. As an adhesive user, you have the ability to… • Achieve lowest total cost of ownership • Minimize internal and external costs. 10-40% savings are typical and achievable. • Increase Mileage • 10-35% mileage advantage is attained through lower density, thermal stability, precise application and aggressive bonding. • Reduce Line and Maintenance Costs • Eliminate char. Less nozzle, module & hose replacements. Reduces line, tank and cleaning costs. • Increase Plant Yield and Throughput • Reduced downtime and rejects. Fast speed of set yields maximum line speeds.
