Craft Pattern’s current focus, and Cremers is driven to bring pro- cesses in-house in order to keep his lead times down. “We do as much as we can


under one roof,” said project manager Steve Shade. “If there is a bottleneck, we look at bringing it in-house. For instance, we do heat treating, shot blasting and broaching at our facility. In the past, these were subcontracted services.” In-house casting is a large part of

provides business flexibility. “We can make a pattern tool,


produce sand molds, pour them and adjust the pattern tooling if needed, all in the same day,” Cremers said. Craft Pattern pours the alu-


minum castings at its facility in Maple Plain. And while all molds


are made in-house, they partner with several local production casting facilities to pour ferrous prototype parts. Many times, Craft Pattern will also perform secondary machining operations in order to supply a finished cast component to its customers.


Cross-Trainers In Craft Pattern’s 24-employee


shop, workers are cross-trained across several skill sets and experts at multi- tasking. Cremers himself, who started at the company as a pattern maker, will step in at times to run a machine, per- form maintenance or make sales calls. Te business’ eight CAD engineers are the same employees producing the tooling and machining the parts. Te overlapping skills lend Craft Pattern flexibility that Shade said is an advan- tage in a business where customers may change models, prints and project requirements on a daily basis. “It can be a high-energy level


experience building prototype parts, but it is also rewarding when the job is complete,” Shade said. “Our require- ments change so fast from the front office to the shop floor and it can be a high pressure environment to com- plete jobs on time. We try to keep a relaxed atmosphere to keep mistakes to a minimum. I want guys on the molding line to be confident in their abilities and alert the staff of poten- tial issues early in the process so that problems can be corrected immedi- ately and effectively.”


Going Up In order for Craft Pattern to


survive in 2008, it needed to find new customers. Cremers understood that would require converting the primar- ily three-axis machining capabilities to four-axis and adding horizontal machining centers. “I had to invest some money to
