CWM is Featured on Village of Bensenville TV Show

Published by:

The Village of Bensenville invited Eric Treiber, President and CEO of Chicago White Metal, to speak as a representative of the company.  The exclusive interview was a comprehensive overview of CWM, the corporate culture, and insights from both Eric Treiber and Village President Frank Soto on the manufacturing field and the beginnings and inner workings of CWM in the modern-day die casting industry.  Watch more here on their discussion.

CWM Location: Die Casting Facility

Chicago White Metal has enjoyed an ideal location of our die casting facility as well as corporate offices, just 10-15 minutes west of O’Hare International Airport.  With the location built from the ground up specifically for CWM, our die casting facility and offices have seen the surrounding industrial park grow tremendously over the years into the manufacturing mecca it is today.

CWM and the Village of Bensenville: A Long-Standing Partnership

CWM moved its die casting facility location to Bensenville in 1977, nearly 40 years ago, expanding the size of of their much smaller metal die casting space to a 76,500 state-of-the-art die casting facility.  Starting off with zinc die casting, CWM has since expanded into magnesium and aluminum die casting manufacturing, as well.

Chicago White Metal has enjoyed a long history in the die casting manufacturing business and has paved the way for not only Illinois die casting companies, but the die casting industry in general.  CWM was the first North American die caster to have earned ISO 14001 certification and receive environmental recognition from the EPA.  In 2001, CWM was the first die caster to achieve ISO 9001:2000 for product design, and in 1995, became one of the first die casting facilities to achieve ISO 9002:1994.

With a history and current day dedication to innovation, Chicago White Metal has put Bensenville and Illinois on the die casting manufacturing map.  Always maintaining a friendly and mutual partnership with Bensenville, this opportunity for CWM to interact directly with Village President Soto was both an honor and a privilege.

Read Between the Lines: Parting Line Placement in Metal Die Casting Design

Published by:

Two halves of a die meet where the parting line exists on the metal die casting
OEM engineers as well as die cast engineers consider several factors when addressing the elements that are involved in metal die casting design.  One of the key elements in this process involves the geometry of the die cast part and how it relates to the placement of the parting lines.

What is a Parting Line?

An engineer within a die cast company knows that die casting dies must be constructed in at least two parts.  When the die is placed within the die cast machine, the two plates come together in order to form the two halves of the part, whether it is in aluminum, magnesium, or zinc alloys being used.

Around the perimeter of the part will be a visible line that runs exactly where the two die would meet.  This line is called the parting line. This line determines which half is the “cover” die and which will be the “ejector” die.  This also is a determinant of how the rest of the part will be designed in conjunction with additional processes.

Why is the Parting Line Important?

The parting line determines the overall design of the part in conjunction with the following considerations:

Cost Efficiency

Metal Die Casting Worker is hand filing an aluminum component at the parting line.

  • Reduction of flash formation
    • Elimination/reduction of trimming, hand filing, or additional flash removal processing.
  • Elimination/reduction of machining.

Engineering Requirements

  • Influences tolerances to be held in the area of the casting.  Tolerance standards must follow NADCA guidelines.
  • Influences draft angles, wall thickness, and geometry considerations.
  • Influences metal flow and casting integrity.

Cosmetic Appearance

  • Designating a parting line to “flow” with the contours of the design will optimize the overall aesthetics of the die casting part.

Cosmetic Surface Finishes vs. No Surface Finishes


Surface finishes for die casting component design should be discussed in the pre-planning phase of the engineering of the part.  It is critical this discussion takes place beforehand because the location of the parting line, the gate, overflows, and vents, should accommodate and not blemish the finish of the part’s surface.

1)      If cosmetic surface requirements are not a priority, the die casting component will be designed in a way where the die halves will utilize the most advantageous casting conditions as well as cost efficiency.

2)      If cosmetic surface requirements are a priority, the die cast engineer will work with you to incorporate design practices and additional processes to efficiently meet your needs.

Who makes the final decision on the Parting Line Location?

The die casting engineer should be the final decision maker on the location of the parting line when working with a metal die casting design.  Because the OEM designer may not be familiar with the importance of the parting line, it should be discussed with the die cast engineer to see what options are available.
