Security vulnerabilities, failures and efficiency losses arose from errors due to the manufacturing processes and design of cases. For maintenance purposes, it is so vital to dismount cases and remove components in a short time.
In classical cases, mobile recorders, time delay relay contacts, hard drives and power converters, poe card, recorder cards are mounted to the body of case by opening holes to the front-back panel and inside of the case and screwing cards to the cases. This study mainly focuses on developing a case without any screws and soldering. Components and cards can be mounted to the case with a click system. The projected case prevents from soldering errors, the jamming during removal of the hard disk, easing for both remote monitoring and re-opening the case by the end user in case of the insertion of a sim card for the internet. In this study, two molds are designed and manufactured using CAD software and classical subtractive manufacturing techniques. Two molds were designed and manufactured for using in extrusion process of aluminum and plastics materials.
Aluminum and plastic parts were produced with extrusion machine. The cards were mounted to the case by clicking. This study improved production processes, reduced both soldering amounts in developing electronic cards and the cost & time delay. It also increased the efficiency, reduced product loss and idle/die change times, provided user convenience, and shortened production time.
