MODERN COLD-FORGING APPLICATIONS FOR THE MANUFACTURE OF COMPLEX AUTOMOTIVE PARTS

The demands for the automobile industries have spearheaded the develop ment of complex precision cold forging of steel. The trend is still co ntinuing toward further sophisticated near-net-shapes thus required. T he precision cold forging of complex automobile parts stays, as it wer e, within a realm of experience-based workmanship, and will be most su ccessful through the total management of the meaningful pre-production trials, the careful preparation of slugs, the satisfactory press perf ormance, and the product and quality assurance system certifications a s well. The compatibility among the Q, C and D levels is another consi deration for the manufacture of over 10(5) pieces in several successiv e production lots, with a Q index of ppm rejection during manufacturin g. Some of the current practices in the Aikoku Alpha Corp. are present ed from these aspects of cold forging of steels.
