Ontario shop takes risks, invests in people, process and technology to improve productivity.


Walking into the Windsor, Ont., facility of Cavalier Tool & Manufacturing is like being in the eye of a moldmaking hurricane: Everything is calm in the walkways, but around you is plenty of motion, with every machine running, making chips, being productive. Really productive.

Established in 1975 the company has an early history that is similar to that of many shops in the area. When the automotive industry was booming, the shop was busy; when the market cooled, so did Cavalier’s business.

It was how the industry worked.

Windsor today is still home to the most tightly grouped number of moldmakers in the country. It’s ubiquitous, almost cliché. But the industry has changed, especially since the recession in 2009. Companies that had been operating in the traditional fashion started to fall by the wayside, closing their doors after decades in business.

Cavalier didn’t want to be another statistic, and that led to change.

Today Cavalier still is known for building medium-sized to large molds for, yes, automotive, but the company also has diversified its product offering to include mold creation for recreational, agricultural, and commercial customers.

Its customer base reads like a who’s who of brand names, and they come to Cavalier for a reason, says Cavalier Tool President Brian Bendig.

“It’s our goal as a company to be a model of moldmaking efficiency,” said Bendig, who is the second generation of his family to run the shop. It was Bendig’s father, Ray, and two partners who first opened the shop 40 years ago.

“Our customer base comes to us because they need what we provide in terms of production and care,” said Bendig. “We like to be challenged. We feel that with the people we have in place and the investments we’ve made in equipment that we can solve any mold problem for any customer.”

You hear that mantra a lot from Bendig. The company’s strategic plan for success mainly revolves around three things: people, process, and equipment. By striving for continual improvement in all three of these areas, he believes that Cavalier will be able to continue its current growth cycle and also push the boundaries of what a 21st century Canadian moldmaker can accomplish.

Brave New World of Manufacturing

The manufacturing world has changed dramatically in the 40 years since Cavalier first opened its doors and began making molds. Supply chains, competition (both domestic and foreign), and customers have all changed, forcing Cavalier to change as well.

In particular, the moldmaking industry has been hard-hit in this part of the country. Gone is the simple work, moved to China and other lower-cost locations. This shift in manufacturing, in combination with the recent recession, caused Cavalier to rethink its business … every part of its business.

“If we want to change the way people think about manufacturing, we need to start now,” said Bendig. “At Cavalier that means a process of continual improvement, innovation, and automation.”

It’s a plan that seems to be working.

In just five years the company has grown its revenue from $8 million per year to more than $30 million. The goal? Double its sales in the next few years.

That means more injection, structural foam, tools with gas assist, multishot, thermoset, compression, and prototype jobs. This work is currently all performed in the company’s 50,000-sq.-ft. shop, which runs 24/7. To reach its sales goals, Cavalier will need to expand the shop, and it’s already planned.

“It all comes down to having the right people and the right equipment at the right time,” said Bendig. “When you have the capability like we do to set up machines and run them constantly, whether it’s with a palletizing system or with parts loaded into a tombstone, it frees you up to perform other work. This reduces costs and increases productivity at the same time.”

Bendig recognized early in his tenure as president that to be at the top of every customer’s contact list the company had to invest in the newest and most complex technology that was available. This has led to a program that continually analyzes the current technology in the shop and replaces older equipment with newer, faster, automated machinery when it’s available. On average, three or four new pieces of equipment are brought into the shop every year.

This type of buying is a large financial outlay, but one that is necessary to both the present and future of the shop, according to Bendig.

“If having a piece of equipment means that we can do something our competition can’t, then it’s simply the cost of doing business,” he said. “Some shops might say they can’t afford to update machinery in this way, but for us, we feel we can’t afford not to.”

One example of Cavalier’s “spend money to make money” strategy is its electrical discharge machining (EDM) operation. In 2012 the company purchased an OPS-Ingersoll Eagle 1200, a gantry-style EDM sinker, becoming one of the first shops in North America to have one on its floor.

“Making an investment in this one EDM alone saved us more than $100,000 in consumable and operational costs in the first year of operation,” said Bendig.

Two more OPS-Ingersoll Eagles (the larger 1400 models) have since been added, sitting together in a line with the other EDMs, which enables all three to be monitored by the company’s EDM experts.

This year Cavalier added an OPS-Ingersoll Eagle V9 high-speed, simultaneous 5-axis milling machine that can create graphite electrodes in a single setup.

“This latest purchase is a big deal for us,” said Bending. “Not only can we create most of our electrodes in a single setup now, but we can also make them much faster. It’s a good example of how we research a tool that can help us, install it on the shop floor, and use it to improve the overall process and reduce costs.”

In the past few years the company also purchased complex multiaxis machining centers, large horizontal machining centers (HMC) designed to machine a large mold plate in one setup, horizontal boring mills, and gun drills.

Sometimes it was simply to improve a machining process, and sometimes these purchases, for example two IMSA gun drills added in 2013 and 2014, were brought in to bring work back into the shop that was being outsourced.

Customizing Machines

The continual improvement process doesn’t end once the equipment is installed on the shop floor, either. That’s when the true changes are just beginning.

When chips from the company’s Toshiba 4-axis boring mills were coming too close to other machines and walkways, the company decided it needed to build custom shrouds around the machines. These enclosures were designed and built in-house and added to the machines.

This is just one example of many around the shop of the company’s willingness to change the status quo and not be afraid of change.

“If you aren’t actively seeking out ways to improve, you already are falling behind,” said Bendig.

For Cavalier this means improving and empowering its employees, not just its equipment. Continual training that uses employee input as a basis helps new employees integrate faster and enables the company to put employees in the best position to succeed.

“If we hire someone with a great background in computers and technology, we should be thinking, in the long-term, about how that person will one day be working with our CAD/CAM team,” said Bendig. “Not everyone in a manufacturing company is going to be running a machine. I think that’s where the general public needs some educating. We definitely need machine operators, but we also need designers, engineers, and sales staff.”

The company’s cyclical program of machine replacement ensures that it will not fall behind other moldmaking shops, no matter where they are located in the world.

“Our competition today is not just down the street,” said Bendig. “If we want to reach our goals — and not just our sales goals but our strategic goals — then we need to keep on top of trends in machine tools, cutting tools, and software.”

Continual Improvement

The company spends a lot of time and energy examining and re-examining its processes. Spindle utilization and other metrics help the production staff refine processes, especially as new technology is integrated. Collaboration between the design staff and the manufacturing teams, and even the sales staff, also helps Cavalier develop better molds in less time.

And that’s what business really is all about at Cavalier. Moldmaking. The shop still sits in the heart of the country’s traditional moldmaking industry, but it is operating just a little differently than everybody else.

Additive Manufacturing Specialist and Injection Mold Manufacturer Adds Wire EDM Capabilities to Enhance Efficiencies

Linear Mold & Engineering, specializing in 3D metal printing and the manufacture of innovative, tight-tolerance injection molds, has added wire EDM to its capabilities


Linear Mold & Engineering, specializing in 3D metal printing and the manufacture of innovative, tighttolerance injection molds, has added wire EDM to its capabilities.

The new Mitsubishi Model MV2400-S wire EDM will serve both the 3D metal printing – Direct Metal Laser Sintering (DMLS) and Selected Laser Melting (SLM) – side of the business as well as the mold manufacturing division. Prior to obtaining this capability, Linear sub-contracted this work, or cut the parts from the base plate on which parts are built using a manual saw, said Mike Misener, General Manager for Linear.

“Performing the cutting manually means that the parts also required a manual post-finishing process to clean the part,” explained Misener. “The wire EDM cuts through the various metals we use regardless of the hardness of the material, leaving a clean, high-quality finish. And it reduces or in some cases eliminates post finishing.”

The 3D printing process is growing as demand for more end-use parts for the aerospace, automotive and medical markets increases. “The wire EDM will help us increase our efficiencies, reduce our build time and improve the overall quality of our sintered metal components,” said Misener. “It also allows us to grow 3D printed parts closer to the plate.”

Linear builds end-use parts as well as mold components such as conformal cooling channels, using the DMLS and SLM processes from a variety of metals including Inconel, Stainless Steel, Cobalt Chrome, Titanium, Aluminum and MS1, a maraging tool steel, having differing levels of hardness. Therefore, the wire EDM will provide efficient, accurate cutting for all types of materials.

Additionally, the wire EDM will allow Linear to cut up to six plates at one time virtually unmanned. And the Mitsubishi MV2400-S cuts within +/- 0.002 inch, and employs a range of high-tech features such as automatic wire feeding, user-friendly controls and internal software capable of accurately calculating machine hours needed to do specific jobs to improve job scheduling
