The impact of changes in automotive power sources and plastic processing technology will have much impact

If the power source is switched to a motor, the demand for machine tools will decrease in the future. Changing the Processing Mode With the development of plastic processing technology, parts previously processed by cutting methods are now more cost-effective than cold forging methods. Compared with plastic processing such as forging and cutting, the former is inferior to the latter in terms of processing time and material utilization. The automobile assembly plant requires auto parts processing plants to reduce prices. On the premise of guaranteeing quality, we will continue to work hard to reduce manufacturing costs. In particular, when parts of new models are used, it is required to reduce the cost by 30% compared with the same kinds of parts before.

To achieve this goal, it is not enough to just consider the rationalization of management. We must comprehensively consider various issues including manufacturing methods. Aida Engineering Co., Ltd., a forging machine tool factory, is actively working hard to finish machining without cutting, grinding, and other finishing operations. In the past, large auto parts factories also proposed this program, reducing the cost by 30% to 35%. Other auto parts factories are also reducing manufacturing costs by reducing cutting. In the future, according to the user's requirements for reducing costs, cutting will be further reduced. No chip processing will be the main means of reducing costs. It is estimated that the use of chipless processing for some parts is a foregone conclusion.

Cutting and grinding processes are still needed, and it is impossible to replace them entirely with plastic processing. The changes in automotive power sources and the development of plastic processing technology will actually have much impact, and it is difficult to predict. It is certain that the demand for machine tools will be reduced in the future. There should be a full understanding of this point.
