Customer
Linamar Group of Companies
Type of Industry
Automotive components and assemblies, motor vehicle parts and accessories.
Problem
Linamar had more than three thousand motor vehicle parts that needed to be completely de-rusted due to some
manufacturing issues. These parts were made of powder metal and had a fine machined finish. It was very important that the
method of rust removal did not harm this surface in any way.
Previous Rust Removal Method
Employees used acid to remove rust. Acid was hazardous and brought many other expenses including
personal protection clothing, gloves, goggles and health and safety risks to the users. Additionally, the acid harmed the
surface of the metal and was not easy to dispose of.
ARMOR Solution
Linamar had a long history as a customer of Armor Protective Packaging® for other rust preventative products and
they called on ARMOR to assist with this 3,000-part rust removal project. An ARMOR technical service representative visited them
within one day. First, ARMOR diagnosed the problem and found that the parts presented small spots of red rust (hydrated oxide -
Fe2O3•H2O), which is typically promoted by contaminates due to exposure to a very corrosive environment. A test was conducted at
the Linamar plant to prove that Metal Rescue™ in fact could effectively remove corrosion per their requirements. Results were
excellent, after 30 minutes of treatment the rust was successfully removed with no side effects to the surface of the part itself
and without risk to the employees.
Results/Savings
The approximate cost to scrap one of the 3,000 rusty parts totaled $16.00/part. By successfully de-rusting all
of the parts, Linamar saved at least $48,000 USD.
