Cleaning for Deep Drawn Metal Stampings

As a manufacturer of deep drawn metal stampings, it is important that you partner with a chemistry provider who has diverse product portfolio and expertise in finding efficiencies in your process.  With a rich history in metal finishing, we have helped deep drawn manufacturers like who are facing issues such as:

Complex Parts Geometry 
Hubbard-Hall is one of the chemistry suppliers who can offer you both solvent and aqueous chemistries.  Our recommendation for which product to use will be based on a few factors such as: process, equipment in place and desired final outcome.

Frequent cleaning bath replacement
The contributing factors for this issue could be lubricants that over saturate the cleaning baths, chelators that are designed to reduce metal contamination but tie up the cleaning chemistry, and phosphate-based/citric acid passivators that interfere with waste treatment operations.

Parts staining/corrosion
If you are experiencing staining/corrosion on your parts after the forming lube has been cleaned off, it may be caused by amine compounds in water emulsifiable lubricants. These compounds have a high pH and can react with soft metals, resulting in oxidation and staining. Although the compounds contain inhibitors, there are limits to their effectiveness.  Learn more.

Scale formation
Conventional chemistries such as silicated cleaners have several advantages such as; safe for all metals, comes in powder or liquid and are inexpensive. However, you cannot use them with certain washers, they can leave an undesirable film, they can cause scale formation and are high sludging.

Wastewater treatment or haul-off issues
Treating the wastewater or hauling away the sludge keeps you in business but doesn’t contribute to your bottom line. Choosing the right chemistry upstream for your cleaning process;

  • Reduces wastewater costs (haul off, overhead and from fines) and keeps operations in compliance
  • Reduces frequent dumping of the cleaning bath, which puts less strain on your wastewater treatment operations
  • Reduces sludge generation by treating waste at the source

Determine your Cleaning Costs

Several factors need to be considered beyond the cost/gallon of cleaning chemistry.

Cleaning is more than picking a chemistry.  The type of alloy and soils, cleanliness & throughput requirements, waste handling and cost all need to be considered.
