Selection of Concepts for Manufacturing Custom Plastic and Metal Components by Integrated Viewing Model

Plastic-metal-components in the contact and connection technology have rising growth figures in many markets and industries. Typical products are molded housings, premolded parts, hybrid or plug board connectors, which find their application in control devices or other mechatronic assemblies.

Already at a very early development phase, the questions for the serial conditions appear, even before the first prototypes are being produced. The binding character of offers, even at this early state, pushes the manufacturers of plastic-metal-components to consider all possible cost-related factors. These include not only the pure product, but also the customer conditions (such as the cycle time, which is the demand numbers in the time interval or the duration of the product life cycle).

For this problem this thesis provides a user-oriented solution model based on a scientific approach.The model contains two additional methods in style of the Toyota Production System to highlight waste. The untypical, but absolutely necessary, is the proactive estimation of expected losses. The Net Equipment Effectiveness looks at the efficiencies of individual production systems in combination of machine, peripherals, tools and personnel. The second method is the value stream mapping, in which the entire process chain from incoming goods to outgoing goods including order specific conditions of the customer are visualized. The manufacturing systems including resources, set-up times, cycle times, lot sizes, etc. Even the loss factors of Net Equipment Effectiveness are listed here. Furthermore, all storage areas are represented with their stock quantity. The company that knows the total costs of planned future manufacturing concepts and is be able to optimize the concepts technically and economically, has a clear competitive advantage over its competitors.
