construction criterion

The economic efficiency strongly depends on how much of the characteristics and possibilities of the process are required for the end use of the produced part. The process as such is by no means inexpensive, however it can enable enormous savings when used selectively. Whether the process is economic for a particular use, has to be examined/verifies, case by case. Thereby it is most important that the design engineer fully understands the possibilities of the MIM process. A part already designed for manufacture by a purching or stamping process is almost certainly more expensive when manufactured with the MIM process, if however, the MIM process is included initially while designing, the possibility of this process can enable the construction of functions of the part which make possible substantial simplifications of the whose constructional unit (assembly group). Often it is possible to reduce the number of parts required for a constructional unit, to eliminate the machining costs for conventionally manufactured parts or to substantially increase the quality of the constructional unit by selecting the appropriate material. All of this can lead to substantial cost savings.
