Capacity Upgrade | Hebei Boao Rubber Adds 2400mm Wide Vulcanization Line, Leading in Manufacturing of Large-Scale Conveyor Belts

To meet the demands of industries such as mining, ports, and power for high-bandwidth, high-intensity, and long-life conveyor belts, Hebei Boao Rubber Technology Co., Ltd. (referred to as "Boao Rubber") has officially launched a 2400mm ultra-wide intelligent vulcanization production line. It has become one of the few enterprises in North China with large-scale production capabilities for large-sized conveyor belts, and its production capacity and technical strength have reached new heights. 

I. Background of Upgrade: Breaking through the bottleneck of large bandwidth supply 

As industrial transportation continues to evolve towards higher capacity, greater efficiency, and longer distances, the demand for conveyor belts over 2000mm in width has skyrocketed. However, most enterprises in the industry are constrained by their equipment, resulting in insufficient production capacity for 2400mm belt widths, long delivery cycles, and poor quality stability, making it difficult to meet the construction schedules and quality requirements of large-scale industrial and mining projects. 
Boao Rubber has been engaged in the research and production of conveyor belts for over 20 years. Leveraging the advantages of the rubber industrial cluster in Boye County, the 2400mm wide vulcanization line that was put into operation this time precisely fills the gap in the regional production capacity for large-sized conveyor belts. It can quickly respond to customers' customized demands and shorten the delivery cycle by more than 30%. 

II. Core Advantages of the Production Line: Intelligent Precision, Quality Upgrade 

Ultra-wide compatibility, complete coverage of specifications 
The new line can produce a full range of conveyor belts with a width of 500–2400mm and a thickness of 8–50mm. The types include nylon (NN), polyester (EP), steel wire rope core (ST), patterned, and edge guards. It meets the requirements for large incline, long-distance, and heavy-load transportation scenarios in industries such as mining, coal, ports, power, and metallurgy. 
2. Intelligent vulcanization, with more stable performance 
The fully automatic temperature-controlled vulcanization system is adopted to precisely control the vulcanization temperature (145–155℃), pressure (1.2–1.8MPa) and time, ensuring uniform inter-layer bonding of the belt, no air bubbles or wrinkles. Combined with a high-precision tension control system, it guarantees uniform longitudinal and transverse force distribution of the belt, reducing the deviation rate by 40% and increasing the peel strength by 20%. 
3. High-end configuration, with greater durability 
The matching special high wear-resistant and high anti-aging rubber formula is adopted. The tensile strength of the covering rubber is ≥ 25 MPa, and the wear rate is ≤ 0.08 mm/10,000 times. The core layer uses high modulus PA66/EP canvas, which is treated with secondary impregnation. The interlayer bonding force is ≥ 12 N/mm. Under heavy-load operation, there is no delamination or layering, and the service life is extended by more than 50%. 

III. Capacity and Value: Cost Reduction and Efficiency Enhancement, Empowering Customers 

Production capacity surge: The newly added production line is designed to have an annual production capacity of 1.2 million square meters. After reaching full production capacity, the company's total annual production capacity will exceed 3 million square meters, enabling it to handle large-scale project batch orders. 

Quality Assurance: The entire process adheres to the ISO9001 quality system. An independent chemical analysis laboratory and physical laboratory are equipped. 28 performance indicators are monitored throughout the process. The products comply with national standards such as GB/T9770 and MT668. The inspection rate of the national rubber quality inspection center in 2025 was 100% qualified. 

Customer Value: The high-bandwidth conveyor belt can reduce the number of conveyors, simplify the equipment layout, and lower the operation and maintenance costs, helping customers improve the conveying efficiency and reduce the overall energy consumption. It has received batch orders from large-scale mines and ports in regions such as North China and Northwest China. 

IV. Future Planning: Continuous Innovation, Leading the Industry 

The commissioning of this 2400mm wide vulcanization line is a crucial step in Boao Rubber's "technology-driven, capacity upgrade, and service value-added" strategy. In the future, the company will continue to increase its research and development investment, focus on breaking through high-strength, high-heat resistance, flame retardant, and environmentally friendly high-end conveyor belt technologies, and improve the "research and development - production - testing - service" full-chain system. With higher-quality products and more efficient services, it will help the industrial conveyor belt industry achieve high-quality development.
