Nabote laser cutting system overcomes cutting pain points and has been implemented at Dongfang Heavy Industry.

The Lingguang series of thick - plate laser cutting systems jointly launched by Nabote Technology and Tuanjie Prima were officially put into use at the production site of Dongfang Heavy Industry in April 2026, achieving two industry records in the field of shipbuilding and heavy steel structure processing: cutting 27 pieces of 12mm carbon steel plates in a single day, and being the first in the industry to use laser cutting for bulb flats. Both breakthroughs point to the same core pain point - the long - term reliance on manual gas cutting and flame cutting for thick - plate blanking in the domestic shipbuilding industry, which is characterized by low efficiency, poor precision, and high post - processing costs.

Pain Point: Traditional Cutting Methods Restrict Shipbuilding Production Capacity

Shipbuilding and heavy steel structure processing are industries that require a large amount of steel plates and strict processing precision. Among them, thick - plate blanking and bulb flat cutting are core processes and also bottleneck links that have not been efficiently solved for a long time.

Taking thick - plate blanking as an example, the industry generally uses flame cutting or plasma cutting. The average daily cutting volume of 12mm carbon steel plates is about 12 to 13 pieces. The cutting section has many burrs and large dimensional deviations. A large amount of manual grinding is required before the next process, resulting in relatively low actual comprehensive efficiency.

Bulb flats are special steel sections dedicated to shipbuilding, with an asymmetric "L" - shaped cross - section - one end is a spherical round head and the other end is a web. This structure makes the cutting much more difficult than that of ordinary flat plates. For a long time, the cutting of bulb flats in the industry has relied on manual gas cutting, which is slow, has rough cut edges, has obvious on - site safety hazards, and cannot meet the increasingly high requirements for shipbuilding precision. Before the Lingguang series of laser cutting systems were put into use, there was no mature laser cutting solution that could be applied on a large scale in the bulb flat cutting process.

Technical Solution: Overcoming Five Engineering Problems One by One

The reason why laser cutting of bulb flats has been a long - standing industry gap is that the special structure brings multiple technical challenges that are superimposed at the same time.

Focus Tracking: The bulb head is an arc surface and the web is a flat surface, with an obvious height difference between them. Ordinary cutting heads cannot be aligned with the heights of the two curved surfaces simultaneously. The Lingguang series of systems uses adaptive focus tracking to achieve dynamic adjustment of the focus during the cutting process.

Laser Reflection Control: The arc surface of the bulb head reflects the laser back, causing energy loss and ablation of optical lenses. The system suppresses harmful reflections and reduces lens wear by optimizing the incident angle and cutting path.

Five - Axis Linkage Path Planning: The cutting of bulb flat bevels, ends, and holes requires five - axis linkage, and the path planning complexity is much higher than that of flat cutting. The system has a built - in dedicated trajectory algorithm based on the cross - sectional shape of bulb flats.

Variable - Power Progressive Control: The bulb head and the web have different thicknesses. When cutting with the same laser beam, the power needs to be increased in the bulb head section and reduced in the web section to achieve continuous gradual change, avoiding the problems of burning through at thin parts and incomplete cutting at thick parts.

Slag Discharge Process Optimization: A semi - enclosed cavity is formed at the bottom of the bulb head, making it difficult for the auxiliary gas to effectively blow away the molten slag. The system improves the slag discharge effect and reduces the cross - section roughness through the cooperation of process parameters and gas path arrangement.

In terms of thick - plate blanking, the Lingguang series of systems adopts a speed strategy of "narrowing the acceleration and deceleration sections and extending the constant - speed section" in response to the constraints of rack stability. Combined with the process database accumulated at multiple sites such as Suqian and Xinjiang, the daily cutting volume has been increased from the industry average of 12 to 13 pieces to 27 pieces, nearly doubling the production capacity.

The maturity of the above - mentioned technical solutions is based on the long - term on - site debugging by the core team of Nabote Technology. General Manager Zhang Xiaolong led the team, and commissioning engineer Xu Jialong and laser process engineer Zhong Quanwei were on - site at Dongfang Heavy Industry throughout the process. The team completed the exploration and verification of a full set of process parameters under conditions of climate discomfort and sudden equipment failures (such as the laser head hitting the plate).

Market Space: Stable Demand in Shipbuilding and Heavy Steel Structure Processing

The domestic shipbuilding market has a stable scale. According to data from the China Association of the National Shipbuilding Industry, China's shipbuilding completion volume has ranked first in the world for many consecutive years, and the annual consumption of steel plates is huge. Thick - plate blanking and section steel cutting are high - frequency processes on the production line. The advantages of laser cutting over traditional methods in terms of precision and efficiency provide obvious room for large - scale replacement of traditional processes.

The heavy steel structure processing market is also a potential extended track. Steel structural parts in fields such as bridges, port equipment, and construction machinery also face the contradiction between the efficiency and precision of thick - plate blanking. The process capabilities of the Lingguang series of systems have a certain scope for horizontal transfer.

Currently, the Lingguang series of equipment has been put into use at customer sites in many parts of the country, and Dongfang Heavy Industry is a benchmark case.

Business Model and Current Progress

At present, Nabote Technology's main business model is direct equipment sales, and its target customers are shipbuilding enterprises and heavy steel structure processing enterprises. The Lingguang series of thick - plate laser cutting machines are customized products jointly launched with Tuanjie Prima, and have been specially developed for the special working conditions of the shipbuilding industry.

The Dongfang Heavy Industry project was launched in April 2026, and the equipment delivery and production line verification have been completed. The production manager of Dongfang Heavy Industry gave a positive evaluation of the cutting effect, believing that the precision of the bulb flat laser - cut products far exceeds that of traditional methods, eliminating the need for subsequent manual grinding, and the daily production capacity of thick plates has also reached a level that was previously unattainable.

Currently, Nabote Technology has not publicly disclosed information related to the financing round and the amount of financing.
