The mold industry development space to increase the future of the mold machine market
The modern mold industry is often referred to as a "non-declining industry," and it's widely considered a key indicator of a city's industrial development. When assessing the maturity of an industrial sector, one of the first things to examine is the state of its mold manufacturing. Cities like Shanghai, Zhejiang’s Beicang and Huangyan, Ningbo, Shenzhen, and Dongguan in Guangdong have invested heavily in advanced machinery such as machining centers, CNC milling machines, and precision spark machines to improve production speed and quality. These advancements have significantly boosted the number of molds produced and enhanced their accuracy. However, despite these improvements, the most fundamental aspect of mold manufacturing—flying mode—has been largely overlooked.
Flying mode, which involves flipping molds during the manufacturing process, has remained at 20th-century levels. Small and medium-sized molds are still manually turned and hammered, while large molds are forcibly flipped using lifting equipment, often resulting in uncontrolled drops. This outdated method leaves lasting damage and hidden risks for the final product. The manual tapping of small and medium molds can lead to several serious issues:
1. It generates significant noise, polluting the working environment.
2. It consumes a lot of physical energy, increasing the risk of work-related accidents due to fatigue.
3. Since mold materials are typically made of medium-carbon steel, which is relatively soft, repeated tapping with copper rods can create deep pits on the mold surface, affecting both appearance and performance. The placement of the copper rod also affects the final mold effect, making it difficult to determine the correct model without considerable experience. Variations in worker judgment can result in inconsistent injection products, such as missing glue or excess glue, leading to more trial runs and longer production times.
For large molds, the manual process is even more dangerous and complex. They are often forced to be flipped using lifting equipment, then dropped freely, creating strong inertia and impact forces that can damage both the equipment and personnel. This poses serious safety risks.
In developed countries like the United States and Japan, this practice was largely phased out in the 20th century. They introduced the first generation of flying die systems—traditional platen clamping machines—which were applied in mold production. In China, many large and medium-sized enterprises have gradually recognized the need to replace manual tapping and forced flipping with automated solutions like mold clamping and remolding machines.
Although traditional platen clamp machines have reduced labor intensity, they still require time-consuming processes, especially for large molds. The mold must be installed on the machine, and pressing with the pressure plate can take over half a day. To address this, industry experts combined mold theory with years of practical experience, working with magnetic and engineering professionals to develop a new generation of flying die machinery. This innovation, based on the principle of memory magnetic locking, introduces an electric permanent magnet chuck locking and closing machine. It eliminates the need for screws, allows for 0-90° horizontal flips, and 0-180° vertical flips, enabling partial fly modes (A and B board modes). It saves significant time, operates via full computer control, and allows for quick, safe, and reliable mold opening in just one minute. This is the only system in the world using permanent magnetic disks, and it can also produce traditional pressure plate locking machines upon request. The production process has successfully transitioned from manual tapping to fully mechanical operation.
