In the precision manufacturing fields of perovskite solar cells, OLED displays, lithium batteries, and functional thin films, coating equipment determines the uniformity and yield of the film layer, and is the most critical link in the production line. Many companies first ask when purchasing: What are the imported brands of coating equipment? Imported equipment does indeed have long-term accumulation in accuracy and stability, but now the technological level of domestic equipment is also rapidly catching up. This article reviews the mainstream imported coating equipment brands on the market and discusses how to choose domestic alternatives.
1、 What are the common brands of imported coating equipment
From a global market perspective, imported coating equipment brands are mainly concentrated in Japan, South Korea, the United States, and Europe, each specializing in different niche areas.
1. Japanese brands: Toray, Hirano, Mitsubishi, etc
Japan is one of the countries with the deepest accumulation of coating equipment technology. The high-precision slit coating equipment developed by Toray Engineering has long been used in processes such as liquid crystal color filters, TFT arrays, semiconductors, and solar cells; Hirano Machinery specializes in high-precision coating, cutting, and composite equipment, which are widely used in the fields of lithium battery separators, optical films, and electronic materials; Mitsubishi Materials also offers slit coating machines with a long history, mainly serving precision coating of LCD panels, high-performance films, and lithium-ion batteries. In addition, Sumitomo Heavy Industries also has strong capabilities in precision fluid control and occupies a place in OLED production lines.
2. Korean brands: DCN, etc
Korean brands are also active in slit coating equipment, such as DCN's desktop slit coating equipment, which is mainly aimed at laboratories and research and development scenarios, suitable for small batch process validation in universities and research institutes, and the price is relatively more affordable compared to mass production equipment.
3. American and European brands: Nordisk FOM、 Valmet, etc
Nordson has obvious technological advantages in precision coating systems and is a choice for many high-end production lines. In Europe, FOM Technologies from Denmark has a good reputation in the field of narrow slit coating, and its equipment is known for its high material utilization rate and low operating costs; Valmet in Finland mainly supplies high-speed external coating machines to the fields of papermaking and specialty coated paper. These brands each have their own strengths, covering a wide range of scenarios from precision electronics to industrial films.
2、 Advantages and disadvantages of imported coating equipment
The reason why imported brands are favored lies in their years of process databases and perfect precision control, especially in terms of stable and consistent mass production, making them suitable for high-end production lines with extremely high yield requirements.
But imported equipment also has obvious shortcomings. Firstly, the high price, often requiring tens of thousands or even millions of upfront investment, has deterred many small and medium-sized enterprises; Secondly, the response of localized services is slow, and once a malfunction occurs, communication across time zones is required, resulting in high after-sales and time costs; Finally, the customization cycle is long and the adjustment of the plan is not flexible enough. These factors have led more and more customers to turn their attention to domestic equipment.
3、 How to choose domestic coating equipment
With the acceleration of commercialization in emerging fields such as perovskite and OLED, domestic coating equipment manufacturers have grown rapidly, gradually catching up with international standards in key indicators such as wide width coating, film thickness uniformity, and material utilization. When choosing domestic equipment, it is recommended to pay attention to three dimensions: first, whether the technical indicators are benchmark, including coating width, film thickness uniformity, repeatability accuracy, and material adaptability; Secondly, whether it supports customization according to the process, such as the adaptability of different sizes and materials; The third is whether the localized service is timely and able to respond quickly to on-site issues.
Taking Shenzhen Baode as an example, as a national high-tech enterprise that has been deeply involved in high-end equipment manufacturing for nearly 20 years, its developed slit coating equipment is dedicated to perovskite solar cells OLED、 Research and development of industries such as lithium batteries, quantum dot LEDs, and OPVs, with a coating width of 50-350mm and a coating thickness of 5-200um, equipment speed of 1-10 meters per minute, and a product qualification rate of not less than 99.5%. While meeting high-precision requirements, we also provide customers with more flexible and economical solutions. If you are evaluating coating equipment manufacturers, you may want to conduct a sample verification based on your own process.
4、 Several suggestions for choosing coating equipment
Firstly, clarify the process requirements. The required coating width, film thickness, and accuracy are completely different between R&D sampling and mass production ramp up, which will directly affect equipment selection. Secondly, pay attention to material utilization rate, which directly determines the material cost for long-term operation. Thirdly, paying attention to after-sales service and selecting suppliers with comprehensive service network coverage and timely response can significantly reduce downtime losses. Fourthly, if conditions permit, it is necessary to use real substrates and equipment for process validation, and speak with data.
Conclusion
Returning to the question of "what are the imported brands of coating equipment", Dongli, Pingno, Mitsubishi, Noxin, FOM, and others do have their own advantages, but equipment procurement is never just about brands, but about whether it matches your process, budget, and long-term operation and maintenance. There are trade-offs between imports and domestic production, and the key is to clarify one's core needs. For customers who pursue cost-effectiveness and fast service, a deep understanding of domestic equipment manufacturers may bring unexpected gains.
