From April 8 to 10, 2025, the Shanghai International Corrugated Exhibition, which has attracted the attention of the global corrugated packaging industry, has come to a successful conclusion. Qingdao JUSTU Machinery Technology Co., Ltd., with the theme of "Intelligent Navigation, Intelligent Manufacturing Future", made a high-profile appearance with its independently developed 2800 fully automatic longitudinal and transverse cutting machine. With its disruptive technological breakthroughs and intelligent solutions, it became the top 3 star exhibitor in terms of customer consultation volume during the exhibition.
1. About the new equipment and technological innovations unveiled at this exhibition
Qingdao JUSTU focused on displaying the following two core equipment at this "China International Corrugated Exhibition". Its technical features and innovative breakthroughs are as follows:
1. 2800 computer thin knife longitudinal cutting and creasing machine (equipped with Siemens electronic control system)
- Technical highlights:
- Ultra-high precision: Through 0.01mm dynamic compensation and mechanical free gap compensation technology, it achieves ±0.1mm slitting accuracy, far exceeding the industry average.
- High-speed synchronization: 450 meters/minute isochronous synchronization speed, combined with IoT intelligent fault prediction function, ensures stability under high-speed operation, and improves order change efficiency by 40%.
- Intelligent energy efficiency management: IoT technology monitors equipment status in real time, improves energy efficiency by 18%, and reduces unplanned downtime.
- Innovation breakthrough:
Compared with traditional longitudinal cutting equipment, the Siemens electronic control system and dynamic compensation technology are deeply integrated for the first time, which solves the problem of precision fluctuation in high-speed slitting, and optimizes production response speed and energy consumption management through intelligent means.
2.2800 and 3300 computer spiral knife cross-cutting machines (INVT four-wheel drive common DC bus solution)
- Technical highlights:
- Four-wheel drive energy-saving technology: adopts a two-way energy flow design to directly feed back the equipment's feedback power to the power grid or supply other motors, with a power recycling rate of 98% and a group energy consumption reduction of 25%.
- Millisecond-level power allocation: more than 30% power saving effect is achieved under multi-machine collaboration, and cutting stability is improved, which is especially suitable for high-speed continuous production scenarios.
- Dynamic balanced power supply: Through peak shaving and valley filling technology, the load fluctuation of the power grid is reduced to ensure the efficient operation of multiple devices in a coordinated manner.
- Innovation breakthrough:
Traditional cross-cutting machines rely on single motor drive, with high energy consumption and delayed response; the new solution realizes "electricity self-circulation" in corrugated equipment for the first time through four-wheel drive coordination and DC bus design, greatly reducing the overall operating cost.
2. Future market positioning and business development concept
1. Market positioning:
- Technology-leading high-end equipment supplier: Focus on high-precision, intelligent, and energy-saving equipment, focus on the mid-to-high-end corrugated packaging market, and meet customers' core needs for cost reduction and efficiency improvement.
- Green smart manufacturing solution provider: Relying on energy efficiency optimization technology (such as four-wheel drive power circulation), promote the industry's low-carbon transformation and strengthen the "green equipment" brand label.
2. Business portfolio:
- Core equipment upgrade: Continuously iterate longitudinal and cross-cutting equipment, deepen the application of IoT and digital twin technology, and provide remote operation and maintenance services.
- Expand overseas markets: With the endorsement of "German technology", layout emerging packaging markets such as Southeast Asia and South America, and establish a localized service system.
[Customer interaction] Three-day reception exceeded expectations
During the exhibition, a total of 486 groups of professional customers from 23 countries were received (of which international customers accounted for 35%), and preliminary cooperation intentions were reached with 8 leading packaging companies in Southeast Asia and the Middle East. An old customer, a listed packaging group in Zhejiang, placed an additional order for 3 equipment on site, confirming the market's deep trust in JUSTU technology.
