1937

  • Chicago White Metal Products was established on October 17, 1937 by Walter G. Treiber, and Samuel Gullo. The business produced zinc castings using the slush casting method (hand pouring hot, molten metal into molds).

1940s

  • CWM purchased their first die casting machine, a used Madison Kipp machine, for $500.00 (on display in CWM’s lobby). Additional die casting machines were soon purchased, allowing CWM to increase metal casting production.

1950s

  • Customer demand for slightly larger parts was increasing, and the current location was too small to handle the extra space and weight. CWM built a new 12,000 sq. ft. facility on the northwest side of Chicago and moved into the new building in 1956.
  • Walter Treiber Jr., our current Chairman, joined the company in 1959.

1960s

  • A long-time customer designed a one cylinder lawn mower, one of the first of its kind, and asked CWM to make the aluminum die casting for the motor housing. Through much trial and error, the process was perfected and CWM became an aluminum die caster.

1970s

  • CWM moved into a new, 76,500 sq. ft. state-of-the-art facility in Bensenville, IL to handle increased die casting demand.

1980s

  • CWM builds a 23,500 sq. ft. addition to the Bensenville plant, serving as an R&D center

1990s

  • Eric Treiber joins the company in 1990.
  • CWM expands again, adding a 25,000 sq. ft. addition to house conventional machining, contract assembly, and CNC machining services.

2000s

  • Eric Treiber becomes President and CEO, following in the footsteps of his father and grandfather.
  • CWM purchases Magmasoft mold flow simulation software to enhance our design capabilities. 

2010s

  • CWM celebrates its 75th year as a leading die casting company.
  • 2016: CWM is one of only 4 die casting companies in North America to upgrade to the 2015 standard for both ISO 9001 and ISO 14001.
