Assembly Planbook - March 2009 - (Page 27) According to Claus, since ramping up, the line has been in continual operation six days a week. Because of its modularity, the system can be easily reconfigured in the future to accommodate new product types or changes in production capacity.

Not surprisingly, keeping four different pin sizes and two different E-ring sizes in stock was often a problem. The process of manually installing the five pins and 10 E-rings was also very time consuming, because operators had to pay close attention to ensure the correct pins all went in the correct holes. To solve the problem, Norica Laurona switched from the solid, machined pins it had been using to a set of selfretaining light-duty coiled pins from Spirol International Corp. (Danielson, CT). Because the new pins are selfretaining, the switch meant the E-rings could be completely done away with. In Coiled Spring Pins Improve Trigger Assembly F ounded in 1917, Norica Laurona (Eibar, Spain) manufactures shotguns, and compressed-air pistols and rifles. Recently, the company found it was having problems manufacturing the trigger assemblies for one of its air rifles because of the pins it was using to hold them together. Each assembly is composed of a housing, a safety lever, three internal mechanisms and the trigger itself. The parts were being held in place with five separate pins, each of which was secured with a pair of E-rings, one at each end. Four of the machined pins shared the same 3-millimeter diameter, but were Sentinel Leak Test Instruments Cincinnati Test Systems’ line of leak test instruments can handle virtually any product leak testing requirement.
