With the gradual development of 3C products towards the trend of light, thin and short, related parts are also more and more high-precision and miniaturization, but where the carbon steel screws in the mobile phone, fan small motor shaft or pinion, etc., are common micro-parts, after the stamping process, will enter the heat treatment stage. According to the research, among the heat treatment technology projects that Taiwan's heat treatment enterprises think are worth developing, the precision heat treatment technology ranks first, which has been recognized by 41% of the enterprises. However, there is no corresponding heat treatment equipment and process research in Taiwan, which shows that the lack of heat treatment technology for fine parts by enterprises also hinders the transformation and upgrading of the industry.

Small parts are very important.

In the modern era of human hands and one machine, it is necessary to know that there are precision screws in the mobile phone and the fan/motor in the notebook also needs to rely on the micro shaft or gear to run. Whether the product can function normally depends on these micro parts. The reason is simple: when the parts are stamped and formed, in order to enhance the strength and toughness of the metal, the material must be uniformly heated to improve the hardness, otherwise the material will be hard and brittle, so the "heat treatment process" plays a key role in the entire production process.

The heat treatment pain point of subtle parts is small and invisible!

Cai Fengchun, chairman of Xiangyi Company, said that with the pulse of the times, intelligent technology and precision machinery have become more mature, and the company's products have also moved towards high-value refinement. However, the biggest bottleneck is heat treatment. Once it cannot be properly solved, the strength and stability of metal parts cannot be improved.

At present, the industry generally uses the traditional large-scale heat treatment system equipment production, the lack of fine parts dedicated heat treatment system equipment and various process parameters. The general heat treatment process includes heating, quenching, material receiving, cleaning, tempering and other steps. As the parts are small and light, all micro parts are mostly wrapped with stainless steel mesh bags, resulting in quenching of the parts stacked together, which is easy to cause poor quality problems such as insufficient torque, brittle fracture, deformation and the like. However, if the mesh bag is not used, the parts will scatter everywhere, affecting the material collection rate. Moreover, due to the small size, sufficient quantities must be collected to carry out heat treatment, and even delivery delays often occur, affecting the overall benefit.

Four innovative designs, continuous micro-component heat treatment system equipment came out.

In order to break through the industrial predicament, Xiangyi Company found a metal center to assist. In view of the fact that an overseas heat treatment equipment costs tens of millions, but only has a single quenching function, the cost performance is really not high for enterprises. The research and development team of the metal center has been insight into the usage habits of the industry all the year round and independently developed special equipment for subtle components to solve the pain points for the industry. For highly complex structures or parts with a diameter of less than 2mm, this equipment can integrate functions such as automatic feeding, real-time monitoring and real-time control of the main heating furnace, innovative oil tank and receiving equipment, intelligent services, etc. It can also quickly replace process modules according to product or functional requirements, reducing the dependence and exploration of human experience. In addition to improving the key structure, the appearance of the equipment has also been reduced from the original 20 to 30 meters long to only 2 to 6 meters in size. 100% independent development has also helped the industry to localize the equipment, and the equipment cost has been reduced by at least 50%.

Won the double material international award, yield/material receiving rate quality assurance

Chairman Cai Fengchun said that the birth of this set of local equipment, built-in intelligent management system, so that they no longer have to queue up. "In the past, the sample delivery period was at least one month, and now the processed parts can be obtained within two days, which can be quickly provided to our customers, greatly improving production efficiency and competitiveness."

Only with good heat treatment technology can the quality be stable and the size shrinkage be within the control range. Moreover, experiments have proved that this "continuous micro-component heat treatment system equipment" solves the pain points of traditional heat treatment, with a material collection rate of 100 and a yield rate of 99%. It has excellent precision and wear resistance characteristics, and its quality reaches international standards. The technology also won the Edison Award (Edison Awards), which has the reputation of the Academy Award for Innovation in 2021, and the R & D100 Global 100 Invention Award.
