HOT MELT ADHESIVE OPTIMIZATION How to optimize ADHESIVE consumption

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

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

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

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

Or. . . 2 Pump pressure Because we increase the pump pressure visual of the glue bead with same nozzle size % increase 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. 5 psi About Ellsworth | Ask The Glue Doctor | Engineering Sales Reps | www. ellsworth. com | 1 -800 -888 -0698

As we move up the value / performance grid, what benefits do we achieve? . . . 1 Adhesives that are more viscosity stable and resist charring. Both avoid having to increase nozzle size and change system pressure. 350 o. F Exposure Test Image provided by H. B. Fuller About Ellsworth | Ask The Glue Doctor | Engineering Sales Reps | www. ellsworth. com | 1 -800 -888 -0698

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.

The price per pound of adhesive is just the tip of the iceberg… Total Cost of Ownership Adhesive Price / lb Maintenance Costs Cost of Parts Line downtime Costs Cost of Low Mileage Cost of Low Yield Cost of Field Failures Image provided by H. B. Fuller About Ellsworth | Ask The Glue Doctor | Engineering Sales Reps | www. ellsworth. com | 1 -800 -888 -0698

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.
