In 1964, Mac Cal was formed to service the Defense and Aerospace industries as a label and overlay maker and soon after expanded its services to precision sheet metal manufacturing. As Mac Cal grew, it focused on hiring talent and encouraged leadership. People, Service, Quality and Speed became the cornerstones to its success as it ventured into machining, painting and silk screening. It is the same determination that allowed the Mac Cal team to once again take on the challenge of launching its cable and contract manufacturing divisions, which include: electro, mechanical, optical and clean room assembly.
