The history of Mack starts in the early days of plastics back in Thomas Edison’s labs. In the early 1900s, Donald S. Kendall was working as a chemist for the Thomas Edison Cos. in New Jersey. While trying to find a good replacement for the wax used in phonograph records he led experiments with recently invented thermoset resins know as urea and Bakelite, the first plastic made from synthetic components.
Intrigued by the commercial potential for these new materials, in 1920, Kendall joined forces with Kenneth W. Macksey to co-found Mack Molding Co. in Little Falls, New Jersey, with three rebuilt injection presses. It was there that Mack made the world’s first ever plastic part used in a commercial product for the Otis Elevator Company. In 1929, Mack expanded by buying a DuPont plant in Wayne, New Jersey, and then a decade later moved to a larger plant in Arlington, Vermont. True to Kendall’s original vision, Mack mostly made bottle caps until World War II. To serve the war effort, Mack switched much of its production to mortar-shell casings and related products.
After the war, the company began molding automotive and refrigerator components for General Motors Corp and its Frigidaire subsidiary. One of its first products for GM was the Indian head logo that adorned the front of all Pontiacs. Mack molded the formerly metal figure from yellow acrylic.
In 1960, the Kendalls bought out their partners and diversified into consumer products such as Timex watch boxes and Schick razor handles.
In 1974, management of the company passed on to Donald S. Kendall III, the founder’s grandson and current Mack CEO. Annual sales totaled about $4 million.
Then IBM asked Mack to make a plastic computer monitor housing. That launched the company into the computer & business equipment industry, which is still one of its primary markets, along with medical, industrial, transportation, energy/environment and consumer.
Today, Mack Molding operates 6 plants in the United States and is ranked among the top 10 non-automotive molders in North America with sales of approximately $500 million and 120 injection presses.
Mack’s mission is Total Customer Satisfaction. While simply stated, it has become the kingpin around which all major decisions are based. Branching out into rapid prototyping and tooling was based on customer input and the need to reduce time-to-market. Expanding the headquarters plant to augment Mack’s contract manufacturing capabilities was in direct response to the needs of the marketplace.
But beyond responding to customers’ needs to further grow the business, Mack also formally measures customer satisfaction on a quarterly basis around four criteria:
- Return rate
- Number of on-time deliveries
- How the customer ranks Mack as a supplier in relation to its competitors
- General feedback from customers
Results are posted in all plants and compensation is directly linked to customer satisfaction and profitability.
As part of its mission, Mack employees embrace the following key values, which serve as the foundation for continued improvement, growth and success of the company:
Customer satisfaction is everyone’s primary job at Mack. Each of us will strive to satisfy the needs of not only our external customers but each of our internal customers as well.
