With the development of die casting industry in China, digitalization and automation have become an inevitable trend. With the further expansion of die casting market, there are more castings with different quality, function and structure requirements. The traditional mold manufacturing technology can not fully meet the demand of opening mold. 3D printing technology has gradually entered the field of die casting.
Of course, at this stage, 3D printing technology has not entered the field of die casting on a large scale. In short, the price and technical threshold of 3D printing technology are still very high. However, it is undeniable that the combination of 3D printing technology and traditional die-casting technology can maximize the advantages of die-casting technology and produce high-quality die-casting parts.
Traditional die casting technology: customer order → mold design → mold manufacturing → mold test → mass production.
3D technology application: customers place an order → directly 3D print out the finished product.
Customer order → 3D printing direct manufacturing mold → mold test → mass production.
From the process point of view, 3D printing technology, mainly in the proofing and mold manufacturing links to replace, with its technical advantages, greatly shorten the manufacturing time.
3D printing technology can directly materialize the data layer from CAD, improve the quality, accuracy and production time of the mold, and the mold design can be more bold, without worrying about many die-casting process restrictions.
However, at present, 3D printing technology is still relatively expensive, so only in the aerospace field, the automotive field is more widely used, other industries, the cost is still a big problem.
However, at this stage, 3D printing technology can rely on small batch orders, that is, orders with high unit price but tight delivery time. This part of orders obviously can't be done according to the traditional thinking of making products by opening mold, so the speed advantage of 3D printing is reflected.
