As the industry's leading manufacturer of sanitary equipment, every year, Hengchang Machinery (HCH) will bring many new ideas and technologies to new and old customers, and its advanced technologies and concepts fully reflect their far-sighted strategic layout. At this year's Nanjing Household Paper Exhibition, the company brought more mature ultrasonic technology applications, unmanned and intelligent full-process solutions.

Successfully addressing the challenge of ultrasonic sealing
According to Mr. Yuan Jun, general manager of Hengchang machinery marketing department, in the past two years, Hengchang's key direction in technology and research and development is more inclined to the application of high-end technology, especially some bottleneck technologies encountered by domestic and foreign equipment, such as the side sealing of pull-up pants.

"In recent years, the Chinese market has been demanding more and more quality baby diapers, and the ultrasonic sealing has a very soft surface and feels good to the touch, so it has been favored by everyone. But the bottleneck is the adaptability of the material and the matching of speed." At present, many manufacturers in the industry are using super soft materials, including hot air cloth and spunbonded cloth with high flexibility. In addition, large manufacturers have been pursuing high production speed. Accordingly, on the one hand, the diaper equipment must meet the adaptability to the material, but also adapt to the requirements of high speed, which poses a high challenge to the equipment supplier.

When several materials are sealed together by ultrasonic waves, it is a difficult problem how to achieve the required sealing force while achieving high-speed production due to the different melting points of the materials. "So all along, the domestic use of heat sealing production speed is generally around 200 pieces per minute, if the speed is further increased, the sealing force will not meet the requirements. In addition, the super soft spunbonded cloth now on the market, although the price is lower than the hot air cloth, but its sealing still has difficulties."

Mr. Yuan Jun is proud that Hengchang is one of the few companies that can successfully meet these challenges. First of all, the speed of its pull-up pants production line has broken through the above limit, reaching more than 800 pieces per minute; second, no matter what kind of soft material is used, Hengchang's equipment can do the job well, and the most important thing is It has no effect on speed.

In the current pursuit of more environmentally friendly products, the non-gelling of sanitary products has triggered heated discussions. Although there are no completely non-gelling products yet, Hengchang's success in solving the application difficulties of ultrasonic sealing in hot air and waist seals will obviously help sanitary products manufacturers take a big step forward.
Careful grinding techniques are very important, and a further step is to apply these cutting-edge technologies to the functionalization of sanitary equipment. For a long time, Hengchang has been committed to serving the middle and high-end market, providing customers with sanitary equipment with core functions, so that its products can stand out in the highly competitive sanitary products market. The application of ultrasonic sealing on the waist seal of pull-up pants is a good example.

Unmanned technology allows dreams to shine into reality
In addition to product features, Hengchang's cutting-edge technology also benefits its customers in the entire production process, such as the unmanned technology they have vigorously developed in recent years. "In the field of domestic sanitary products and equipment, we are the first company that has put forward a plan in a real sense and has realized commercialization. We have let intelligence really enter the workshop of sanitary products manufacturers." Mr. Yuan Jun said.

The real realization of unmanned here is not simply adding robots to exchange materials, or simply realizing production monitoring, "When there is a problem in a certain part of the production, not only to monitor the situation in real time, but more importantly, to respond quickly to solve the problem. Then the host obviously has to be equipped with more monitoring and automatic error correction units, which all come at a cost."

Although China's demographic dividend is no longer, the labor cost is still acceptable for the sanitary products industry, especially for some links that do not require high technical content. Then the customer obviously has to consider between the investment cost required to realize the full automation of the production line and the corresponding labor cost.

From a long-term perspective, unmanned is the general trend. Mr. Yuan Jun said: "What we are doing now is also to prepare for the truly unmanned and intelligent era in the future. After all, only leading the market can take the lead. At present, Hengchang has realized the unmanned technology that can be commercialized in many key links, and has been adopted by very forward-looking leading enterprises. I believe that after the industry has seen the advantages and benefits of unmanned technology, small and medium-sized enterprises will follow suit." From the laying of unmanned materials, unmanned packing and even unmanned factories, Hengchang is gradually bringing the dream of unmanned into reality.

In the current fierce competition in the Chinese sanitary products market, whether it is the functionality of the product or the high quality of the product, in the final analysis, it is not only the product characteristics that determine whether the brand can survive, but also a decisive factor-cost control. Those who have begun to advance the layout of unmanned, intelligent technology brand, is also based on this consideration.

"So we say that to see whether a brand can have the last laugh is actually to see whether its early layout is prudent and whether it has a forward-looking strategic vision. These all determine their current and future investment direction and focus." Mr. Yuan Jun finally said, "Hengchang is very happy to cooperate with such customers and let our truly commercial solutions help them move towards a successful future."
