DIE SLICK® 1548 C

CASE STUDY – MACHINING & GRINDING

 

CHALLENGES


 

A leading west coast die caster of aluminum and zinc alloys was experiencing problems with the powder painting of castings:

  • They were experiencing a high volume of fallout (25-30%) due to blisters appearing on the aluminum castings after powder coating
  • GW Smith immediately stepped in to help identify possible causes and to remedy the fallout situation
  • Increased risk of downtime due to blinding of filtration devices

 

THE SOLUTION


 

  • GW Smith collaborated with not only the customer but with the paint supplier, paint vendor, and die manufacturer to get to the root cause
  • Castings were sent to GW Smith lab for testing for any possible residue that might contribute to out-gassing from the die spray/plunger lube
  • An on-site audit of the existing die caster and powder painter’s process and materials was conducted
  • Sample castings were sent to an alternative powder paint source, to test for similar results
  • A GW Smith competitor’s die spray and plunger lube were tested on the same machines
