Laser Manufacturer News: As an advanced laser source supplier for precision manufacturing, what are the advantages of GZTECH in terms of R&D accumulation, product technology, and practical applications?

Dr. Huang Zhihua of GZTECH: In 2022, GZTECH preliminarily completed the market layout with Wuhan as the production and R&D center, and Shenzhen, Suzhou, and Jinan as the sales and service centers in South China, East China, and North China, respectively.

In fact, in the past few years, GZTECH's R&D investment each year accounted for no less than 10% of its revenue, because high-intensity investment guarantees the company's core competitiveness, and continuous high-intensity investment is a marathon that will not stop in the future.

Thanks to the multiple-point layout, despite the impact of pandemic control measures in various regions in 2022, GZTECH has always been able to ensure stable operation of the core business and minimize adverse effects. In 2022, we achieved about 80% of the planned targets at the beginning of the year and still achieved high-speed business growth in the unfavorable situation of the pandemic.

In addition, relying on a young team, GZTECH has also made breakthroughs in market development and new product research and development.

Laser Manufacturer News: In addition to domestic business, GZTECH has also begun to initiate overseas business. Could you tell me how the company is expanding the overseas market?

Dr. Huang Zhihua of GZTECH: In addition to domestic business, GZTECH started to expand foreign trade business at the end of 2021.

After more than a year of efforts, the company has made some breakthroughs in the foreign trade market, and has had some transactional customers in India, Brazil, Mexico, and Europe, and the customers are very satisfied with the products. With the reintegration of the global manufacturing supply chain, the overseas market will become an important market segment for the laser industry in the future.

Laser Manufacturer News: In recent years, the development of China's laser industry has been rapid, and many excellent enterprises have emerged. What gaps do you think we still have compared to foreign laser powers? What are our advantages?

Dr. Huang Zhihua of GZTECH: In recent years, China's laser industry has developed rapidly and gradually realized independent research and development of some core technologies and devices. However, compared with laser powers abroad, there are still certain gaps in our laser industry: First, there is a technological gap, such as disk laser with fast speed, which may not have matching products in China yet; Compared with this kind of old-fashioned laser companies with deep accumulation in technology and products, IPG has a complete layout in the field of fiber lasers. Second, there is a gap in application. Many applications were first developed abroad, where foreign companies could access the most advanced applications and improve product performance according to product requirements. Third, there is a gap in product quality and low-price competition. Some laser companies have given up the performance requirements and quality control of products in order to pursue price advantages.

Of course, in addition to the gaps, Chinese laser companies also have their own advantages: First, facing a vast domestic market, they can provide more efficient and convenient localized services; Second, in recent years, domestic enterprise technical research and development capabilities have improved rapidly, and they can propose their own precision machining product solutions; Third, they have cost-performance advantages in product iteration and upgrading.

As is well known, the domestic laser industry has been continuously promoting the localization process, from the earliest core components such as fiber materials and optical devices, even electronic control chips were imported, to now the pump sources, fibers, and devices have basically achieved localization, and some core materials are still being promoted for localization.

It is worth mentioning that the overall product development capabilities of the domestic laser industry and the upstream and downstream supporting industrial chains are becoming more and more perfect. In the field of lasers, there are many entrepreneurs who originate from research institutes or returned from overseas. This represents that the entire Chinese manufacturing industry is constantly expanding towards high-end and gradually realizing import substitution.

Laser Manufacturer News: What are your thoughts on the development trends of lasers? How do you view the future development direction of China's laser industry?

Dr. Huang Zhihua of GZTECH: For China's laser industry, industrial laser equipment has seen rapid development over the past decade, with an increasingly broad range of applications. However, compared to many other industrial sectors, the laser industry is still relatively small.

If lasers can become a fundamental tool for future intelligent manufacturing, the application of laser equipment will expand significantly, promoting the continued high-speed development of the laser industry. The penetration rate of China's laser industry in the entire manufacturing industry is still low, and there are still a large number of unexpanded areas to be developed, and the future market space is still large.

For GZTECH, on the one hand, we have benefited from the localization achievements of the laser industry chain in the past ten years; on the other hand, we are also promoters of progress and innovation in subdivision categories of laser products.

I think laser companies should actively embrace changes in the times, embrace new industries and applications, strive to develop new products, and expand incremental markets.

In the future, GZTECH will focus on completing the categories of industrial laser products, expanding customer groups and application industries, and strengthening brand recognition and market position.
