The earliest application of the mold, known as the "mother of industry", dates back to ancient times and made an indelible contribution to the path of industrial development. However, with the advancement of technology and the upgrading of machine tools, the mold industry is also facing the impact of various internal and external factors.
Rising raw material prices, manufacturing costs continue to rise
Basically, the entire manufacturing industry will be directly affected by the price of upstream raw materials, and the mold industry is the first to bear the brunt. In recent years, due to the increase in mineral prices, labor, transportation, and increased land price costs, raw material prices have risen and remain high.
The mold industry, which is very dependent on raw materials, is the first to be impacted, and raw materials are rising, which means that the production costs of mold manufacturing enterprises are rising. Cost competition can be said to be an important competitive mode among enterprises. Under the weight of corporate operating costs, reducing marketing costs may become one of the choices for companies to reduce operating costs. Due to changes in the prices of raw materials, many mold manufacturing companies have received large orders before the completion of the loss or even the loss, which has dealt a heavy blow to the company's capital turnover and development.
However, the rise in raw material prices is a double-edged sword for companies and industries. At the enterprise level, the rise of raw materials is not a rare opportunity for industry-quality companies with more scientific, leaner and more efficient management. The product structure of these enterprises is relatively reasonable, the proportion of high value-added products is large, and the products have certain technical barriers, are not easy to copy, and have advantages and competitiveness in terms of price. On the contrary, the rise of raw materials will also speed up the elimination of low-end and inferior enterprises. It may be a disaster for enterprises that are still extensive in management and have serious product homogeneity. In the early stage, due to the large demand for coated abrasives and low barriers to entry, some enterprises originally relied on low-cost competition strategies to support with meager profits. Under the current situation, there is really no order, and orders are more ambiguous. It will be even more difficult for the material costs of the meager profits to be increased.
3D printing puts pressure on the traditional mold industry
As a mature technology that is gradually mature, 3D printing has developed rapidly in recent years. Various research results have emerged, which has caused great pressure on the mold industry. In some areas, it has gradually begun to subvert mold technology and form a direct competitive relationship with it.
The following small series for everyone to briefly introduce the difference between traditional mold and 3D printing. First, in production applications, molds must withstand wear and are economical. Therefore, most of the molds are made of steel, and some are even made of hard alloy. 3D printing is based on the actual needs of users. The current 3D printing materials are very extensive, and new types of suitable materials are available. Secondly, the traditional mold is to draw the mold drawing with 3D modeling software such as PRO-E, and after continuous adjustment to achieve the final molding effect, it is made by tools such as machine tools; 3D printing adopts the mode of additive manufacturing, and the material layer is A layer of overlays eventually forms the desired model.
Again, the product is used. Traditional molds are mainly used for traditional injection molding, die-casting, rubber and stamping. 3D printing is currently used for small and complex parts manufacturing, and large parts need to be assembled by integral printing. Then the product strength and precision, after years of development of traditional molds, the technology is mature, the product can confirm the strength according to user needs, and the precision is also high; the strength and precision of 3D printing are related to many comprehensive factors, such as the selected materials. The accuracy of the bad, 3D model map and the quality of the 3D printer all determine the accuracy of the final product, and the strength is acceptable.
Finally, processing efficiency and time. The traditional mold processing speed is fast, the mass production economy is good, but the economics of single piece and small batch are poor; while the 3D printing molding time is long, the mass production is economically poor, and the economics of single piece and small batch are good.
In summary, it can be known that 3D printing is not suitable for mass production at present, and traditional mold manufacturing still has obvious advantages in mass production in China. In the field of non-bulk, precision requirements are not very high, the mold does not have alternatives. . In the non-bulk, sophisticated, cutting-edge product manufacturing, 3D printing applications have great prospects, such as aerospace, medical equipment and other fields. At present, 3D technology is only for a single piece of small-volume complex shape, and the mold is aimed at large quantities, standard parts and common parts, which are not in conflict with each other, but many places can complement each other.
Every industry will encounter the influence and impact of various internal and external factors in the development process, and the mold industry is no exception. However, in the face of difficulties and obstacles, mold manufacturing enterprises should actively seek change and unity, take the initiative to meet the advent of the era of intelligent manufacturing, enhance the gold content of product technology, reduce production energy consumption, and make the domestic mold industry become a gold made in China. business card.
