The global Double Belt Press (DBP) market size is predicted to grow from US$ 134 million in 2025 to US$ 177 million in 2031; it is expected to grow at a CAGR of 4.8% from 2025 to 2031.
Working principle: Two circulating steel belts run in the press body close to the rollers or chain blankets, the lower hot platen is fixed on the lower support surface of the frame, and the upper hot platen transmits pressure and heat through multiple groups of oil cylinders that can move up and down. The two chain blankets respectively surround the upper and lower hot platens and run at half the speed of the steel belts. Driven by the driving roller, the steel belt drives the rollers or chain blankets to roll purely on the hot press. The pre-pressed slab is sent to the press entrance with an entry angle by the conveyor, and then enters the press driven by the steel belt. At the entrance, the slab is gradually compressed and a large amount of gas in the slab is squeezed out. The temperature of the extruded gas rises due to the heating of the slab, and most of it enters the slab to be pressed to preheat the slab to be pressed. The slab continues to run with the steel belt and is pressurized and heated. The process of pressure and temperature stage changes that meet the requirements of slab hot pressing is completed in the entire hot press area. Then the finished plate is gradually separated from the steel belt driven by the steel belt and sent to the plate discharge conveyor.
As an efficient continuous production equipment, the double belt press (DBP) has been increasingly used in many industries in recent years.
First, with the improvement of industrialization level and the continuous advancement of production technology, the application scope of double belt press has gradually expanded. The production demand of composite materials, especially carbon fiber and glass fiber reinforced plastics, continues to grow, and double belt press has become an indispensable and important equipment.
Secondly, environmental protection and sustainable development have also promoted the technological progress of double belt press. With the increasing global attention to energy conservation, emission reduction and environmental protection standards, enterprises have put forward higher requirements for the energy efficiency and environmental impact of equipment. The efficient heating and pressurizing characteristics of double belt press make it excellent in energy consumption and production efficiency, which is in line with the trend of energy conservation and environmental protection.
However, the market development of double belt press still faces some challenges. First, the initial investment of equipment is high, and the manufacturing and maintenance costs are also expensive, which is a considerable burden for small and medium-sized enterprises. Although high production efficiency can bring considerable returns in long-term operation, high equipment investment is still a key factor for many companies to choose whether to adopt double belt press. Secondly, although the double steel belt press can process a variety of materials, the adaptability problem for some special materials still exists, especially for materials with high viscosity or poor fluidity, which may require additional technical improvements and adaptations.
