The coating die is called the heart of the coating machine. It is an essential equipment for high-speed quantitative coating and a key device to improve product quality and yield.
Gaogong Lithium Battery learned that with the rapid development of the new energy vehicle industry, the supply capacity and performance of power batteries are required to be continuously improved. This also puts forward higher requirements for the coating process including speed, efficiency, yield, and cost. Such as: the speed should reach 80m/min-120m/min; cleaning and changing time <1 hour, debugging time <15 minutes; real-time monitoring and real-time adjustment; reducing debugging costs, etc.
This also means that continuing to use the previous coating process can no longer meet the requirements of power battery companies. Judging from the production lines of leading companies such as CATL and BYD, they have begun to try to introduce new processes and equipment.
As an innovative enterprise centered on the research and development of coating technology, Mannst has taken "making coating simple" as the core of the company's development since its inception, to meet the continuous changing needs of power batteries for coating processes , to carry the banner of localized replacement of coating die heads.
Reviewing the development of the past ten years, in the coating die market where imported products are rampant, Manst relies on its strong technical strength, reliable customized solutions and timely response services to tear open the coating die abruptly. The opening of domestic application has led the domestic die head market to continuously achieve breakthrough development.
From differential threads, differential heads, push-pull rod adjustable single-layer coating dies, to the introduction of technologically advanced products such as double-layer coating dies and fully automatic coating dies, Manst's technical strength has continued to rise. This is the result of Manst's firm exploration and innovation since its establishment, and it is also the value proposition that has been continuously highlighted in its development process.
Make coating "simple"
Rewind the time pointer to ten years ago, when the imported die head formed an absolute monopoly in the domestic market relying on the long-term technical barriers. At the same time, due to the fixed cavity design of the imported die head, the company needs to adjust the slurry to adapt to the die head, and the high price, frequent application problems and lagging after-sales service make the imported die head a criticism of the industry.
In this context, the call for localized replacement of coating die heads has begun to rise, which has also prompted the birth of a number of domestic coating die head companies, and Mannst is one of them.
Since its establishment, Manst has established an independent product R&D and design team. Relying on its many years of experience in the lithium battery industry, Manst has designed its die products according to the characteristics of different slurries and the specific requirements of different use environments. . Coating is made simple through technical adaptability.
Compared with imported products with a fixed die head and a small number of cavity designs, the advantage of Manst products is that, under the premise that the precision and stability are comparable to imported products, they can be designed according to the specific needs and specific characteristics of battery companies. stronger product.
In Manst's view, due to the differences in technology and product routes of various lithium battery companies, the applicability of the technology can better fit the development of each company. Being able to combine customers' product needs and provide a full range of services to create truly valuable products for customers is the real competitive barrier for equipment companies.
In the process of realizing the localization of coating, Manst's maintenance service and after-sales team are also particularly commendable.
In the process of realizing the localization of coating, Manst's maintenance service and after-sales team are also particularly worthy of praise. In fact, in the Chinese market where the imported die head was hunted, MANST was the first to achieve a market breakthrough. After sales team and service in die repair. road.
At that time, due to the fact that there were only agents in China for imported products, or the number of technicians and equipment was scarce, resulting in "incapable of doing" after-sales maintenance. A large number of lithium battery manufacturing enterprise customers.
Founded only three years ago, since 2017, Manst's die head business has rapidly expanded from the Pearl River Delta to the whole country, and has firmly grasped the after-sales maintenance business of coating die heads in the Chinese market. Since 2019, Manst has become an irreplaceable supplier of die products and services for mainstream domestic battery factories.
The market combination of "customized products + quality assurance + after-sales service" has also become the core fulcrum of Manst to leverage the localization market of coating die heads.
New technology strengthens new power
With the emergence of new technologies such as blade batteries, thicker cell sizes, and new functional coatings, the speed and width requirements of the coating machine have changed, which has also brought new challenges to the coating die.
In order to solve the new demands of the coating process, Manst has launched two major products, the automatic coating die and the double-layer coating die.
Compared with the traditional manual adjustment die, the advantage of the Manst automatic coating die is that it can introduce more monitoring points (cavity pressure distribution, temperature, mass flow); the position of the adjustment block is electrically adjusted (±1um ); adjustment process visualization; multiple closed-loop adjustment; Cov 0.35%-0.45%→0.2%-0.3%; greatly shorten the debugging time, reduce debugging waste and other advantages.
Based on the analysis of the factors that make the slurry into pole pieces, through artificial intelligence deep learning empowerment, the continuous accumulation of massive data continues to support the optimization of the algorithm model, supplemented by an automatic closed-loop control system, a complete operating system, fully automatic die head It can realize automatic adaptation to the process, automatic adjustment, and precise automatic control of the overall coating process.
The characteristics of the Manst double-layer coating die are that it can realize double-layer co-extrusion coating, specific flow channel structure design, adjustable double-layer density, optional adjustment method, and customized installation size can be compatible with existing ones. Simple docking of the coating machine. At the same time, the customized cavity and lip design can meet different process requirements.

More importantly, by using special alloy materials, new steel and the industry's first coating technology, Manst has solved the battery safety risk caused by wear of the coating die, and has excellent wear resistance and corrosion resistance. And it can achieve the effect of higher energy density of the battery under the same rate performance and better rate performance under the same energy density.
Gaogong Lithium Battery has learned that at present, Manst's fully automatic coating die and double-layer coating die products have been gradually applied in head power battery enterprises.
It can be seen that, following the footsteps of leading power battery companies, adapting to the development of new processes and new materials, and constantly completing technological changes, Manst makes coating "simple".
Die head market pattern will be reshaped
With the rise of Chinese die-head enterprises, the competition pattern of the overseas die-head monopoly market is changing.
From a macro perspective, Chinese equipment companies are playing an increasingly important role in the new round of global power battery capacity and new infrastructure. Whether it is Chinese, Korean or European, they are beginning to prefer Chinese companies in equipment selection. Including Chinese coating die enterprises.
From a microscopic point of view, China's leading coating die companies have begun to enter the vision of world-class OEMs such as Volkswagen and Tesla, including in-depth technical exchanges and supply chain access.
At present, the power battery in the European market is developing rapidly, and the competition of coating dies in the European market is imminent. Whether it is the gap between market growth and overseas die supply, or the rapid rise of Chinese die companies relying on technology, production capacity, cost, and services, in the new cycle of power battery development, the die market pattern will begin to reshape.
And Chinese coating die companies represented by Manst will also be able to taste a new round of growth dividends in the power battery market.
It is reported that while increasing the proportion of domestic die replacement, Manst has accelerated its entry into the European market in order to further expand its market share. Prior to this, the company has already prepared corresponding technical reserves and talent reserves.
It can be seen that, as the head force of the domestic coating die, Manst has made sufficient preparations in the dimensions of technology research and development, product layout, market adjustment, and customer development. Under the outbreak of a new round of lithium battery market. Manst's market share in the field of coating die is also expected to further increase.
