Chicago White Metal Casting Ornamental and Mechanical Products was founded on October 17, 1937年作者:Walter G. Treiber, (President) and Samuel Gullo, (Secy/Treas). The 公司’s first location was near the south side of Chicago, on the third floor of a loft building with no elevator. Walter Treiber and Samuel Gullo saw an opportunity to produce slush castings (hand pouring molten metal into molds) of better quality and with a more decorative appearance than other current market offerings.

The slush casting business continued to grow, primarily serving the lamp base industry and the casket corner industry. The molds were designed and hand built by Walter Treiber, while Samuel Gullo found customers to buy the castings.

The early World War II years brought about significant changes in the 公司. 第一个, 并且对未来具有重大意义, one of Walter Treiber’s close friends who was in the machinery business convinced him to buy a used Kipp cast 压铸 machine for $500.00. As money was very tight for the young 公司, Walter’s wife Madeline loaned the 公司 $500.00. Madeline Treiber at the time was working in the household of one of the founders of Sears Roebuck. This original Kipp machine is on permanent display in the CWM Lobby.

在第一台机器投入使用后, the aggressive entrepreneurs saw more opportunities to produce greater quantities of this new type of casting. Having relocated to a larger 设施 in the early 40’s, they could now accommodate the addition of many more of these small 压铸 machines, where the opening and closing mechanisms were hand operated, the molten metal was injected into the molds under approximately 100 lbs. 空气压力.


While still heavily involved in slush casting, the 压铸 portion of CWM’s business continued to grow, 但只是用更小的组件.

Customer demand for slightly larger parts was increasing and the current location, with limited size and floor weight restrictions, forced the 公司 to once again consider a move.

CWM commissioned an architect to design a new plant, the first of which to be owned by the 公司 on the northwest side of Chicago. In mid 1956 CWM moved into this new 12,000 sq. ft. 设施. Still only producing small 锌 压铸s and slush castings, the opportunity to grow presented itself with the overall economy expanding. 沃尔特Treiber小., current Chairman of the Board joined the 公司 in mid 1959.



Once firmly situated in the larger 设施, CWM was able to meet increased needs for larger 锌 压铸s. The slush casting business was declining and was sold off to a friendly competitor, allowing the primary focus to be the growth of the 压铸 segment.

In the mid 60’s a very good customer designed a one cylinder lawn mower, 这是第一批, insisted that CWM make the 铝 压铸 for the motor housing. This was a tremendous challenge for the 公司. 第一个, a building had to be constructed to house the new 铝 压铸 machine. Then came the tasks of designing and building a very large die for the housing, having little background knowledge of how it would work, ultimately producing a very complicated casting with steel inserts cast in place. After much trial and error and a very patient customer everything worked and CWM was in the 铝 压铸 business.


CWM now offered 铝 and 锌 压铸s for a narrow niche market that required very highly cosmetic and close toleranced castings. 用它, CWM’s market grew beyond what had historically been a geographical area of 250 miles from Chicago.

A corporate change occurred in 1973 when founding partner Samuel Gullo retired from the 公司. The Treiber family purchased his 50% share and increased 公司 ownership to 100% which is the status today. As CWM was an industry leader in adopting new automated procedures, (e.g., 全自动压铸机, improved die making procedures) many new customers were attracted in the niche markets the 公司 was focusing on more and more.

In 1971, CWM purchased seven acres for future growth 在Bensenville, IL. (Western boundary of O’Hare Airport) and started very preliminary plans for long term growth. With the buyout of Samuel Gullo, this plan was delayed until the mid 70’s. During the intervening period, 沃尔特Treiber小. visited 压铸 factories in many parts of the world to solicit ideas for the new plant. 在1974年初, an architect was hired and with very close cooperation, CWM’s state of the art 压铸 设施 was completed in May 1975. 该公司从大约. 18,500 sq. ft. 76500平方. ft. 在Bensenville.

With a state-of-the-art 压铸 设施, CWM吸引了欧洲的新客户, 中东, 远东, 加拿大, 等. This also started CWM’s very early venture into hot chamber 镁 压铸. As an industry, it had for all purposes died in the U.S. due to a single material supplier and highly volatile pricing. 然而,小沃尔特·特雷伯. actually saw this as an opportunity for growth. 在接下来的30多年里, CWM continued to effectively grow the hot chamber 镁 压铸 business to its present-day success.

In 1985, once again anticipating the future needs of our customers, Walter Treiber commissioned our architect to design and build an R&D设施. 两层楼的复杂, situated at the NW corner of CWM’s structure, 今天我们的工程技术, 销售/市场营销, 过程, 采购, 和IT部门.

In 1988, Carolyn Treiber joined the 公司 and worked with our extensive sales representative organization. Carolyn continues to serve CWM as a Corporate Director.


In 1990, Eric Treiber joined CWM, following in the footsteps of his father and grandfather. The global economy was heating up at a record pace. CWM’s customers favored our strategy of providing them with complete “value added” solutions. CNC 加工 was becoming a much more prevalent service offering along with contract assembly. In what was considered an extremely bold move, in 1992 CWM built a 25,000 sq. ft. addition to house conventional 加工, contract assembly, CNC 加工 services. The 公司 was now well positioned to support an incredible influx of business opportunities that would materialize between 1995 – 2000.

To support quickly growing domestic and international business, management knew that enhancements to our quality structure would be required. In 1994, the management team embarked on a journey to adopt ISO 9001 registration, 1995年完成了哪些工作. 成功地解决了这个障碍, sights were set on ISO 14001 registration which was accomplished in 1999. CWM was the first 压铸 公司 in the U.S. 执行本环境标准.

The dawn of a new millennium brought both excitement about the opportunities to come and extreme challenges as a result of the changing economic landscape. The early 2000’s saw a major pullback in the technology markets due to overbuilding that took place in prior years, coupled with a transition to offshore sourcing in the manufacturing sector. 美国.S. 压铸 industry was hit very hard and many of our competitors did not survive.

CWM worked diligently during these tumultuous times with the support of a dedicated, 忠诚的, agile team in order to ensure that we are well-positioned to meet the ever-evolving needs of our current and future customers. 

In December of 2009, Eric Treiber was appointed President and Chief Executive Officer. With this new post, Eric became the third generation of his family to lead the business.


CWM saw two big milestones in the 2010s as we celebrated our 75th anniversary in 2012 and our 80th anniversary in 2017. These milestones are significant because less than 25% of companies make it through their first three years, 只有10%的人活到75岁以上.

CWM has also remained extremely environmentally conscious. In 2016, we became one of only 4 压铸 companies in North America to upgrade to the 2015 standard for both ISO 9001 and ISO 14001. 今天, Chicago White Metal remains committed to our founding principles of service, 专业知识, 和完整性. We continue to develop new and innovative manufacturing solutions for our customers.
