Manufacturing The Jastram Factory contains a 1,400 m² machine shop and 600 m² electronics shop. These facilities, along with our skilled machinists and technicians, allow us to produce and maintain a high level of quality control. Raw and ﬁnished goods are stored in two different on-site warehouses occupying 1,675 m². Using our own machine and electronics shops allows us to maintain strict control over the quality of the workmanship that goes into our products. When outsourcing, Jastram maintains control of the ﬁnal assembly and extensively tests the products in-house. This process allows us to maintain our high level of quality assurance and workmanship.
