At present, recycled foam particles have been used in textiles, automobiles, food and beverage packaging, and consumer electronics. This has also driven the steady development of the foam pelletizer industry. However, there is still a shortage of technology in the foam pelletizer industry in China, and the exploration and development of new technology roads is still very long.
There is a shortage of domestic foam pelletizer technology. However, due to the lack of domestic production technology, the production process is inferior to foreign products, so the domestic foam pelletizer production line still has a certain gap with respect to foreign countries. There are still many deficiencies in domestic products, imported plastics. The number of machinery is also growing rapidly, so the domestic foam pelletizer production line has a long way to go.
Foam granulators move to the top of the industry; technology becomes a stumbling block
The 21st century is the century of environmental protection. Environmental issues are increasingly important. Resources and energy are becoming more intense. In order to meet the requirements of the new era, foam granulators, foam pelletizers, and waste foam pelletizers are required to be able to meet market demands for packaging quality and quantity. In addition to the ever-increasing demands, it is necessary to insist on saving resources as the starting point.
With the continuous development of new materials, new products and new processes of foam pelletizers, more and more foam pelletizer production lines are developing towards multi-functional and environmentally-friendly types, and they are continuously expanding into other application fields. In order to have a wider range of applications, foam pelletizers must have better production performance, research and development capabilities, and higher quality production processes to meet the needs of the waste recycling industry.
Foam granulators will be highly efficient and multifunctional in the next four directions: The high efficiency of plastic machinery is mainly reflected in high output, low energy consumption, and low manufacturing costs. In terms of function, the screw extruder has been used not only for the extrusion molding and mixing processing of polymer materials, but its use has been broadened to food, feed, electrodes, explosives, building materials, packaging, pulp, ceramics and other fields. In addition, the "one-step extrusion process" in which the kneading granulation and extrusion molding processes are combined is also worthy of attention.
Large-scale and precise: Realizing the large-scale production of plastic machinery and equipment can reduce production costs, which is more obvious in large twin-screw foam granulation units, blown film units, and pipe extrusion units. The precision can improve the gold content of the product. For example, multi-layer co-extruded composite films need precision extrusion, and as an important means to realize precise extrusion, the melt gear pump must intensify its efforts in development research.
Modularization and specialization: Modular production can meet the special requirements of different users, shorten the research and development cycle of new products, and strive for greater market share; and professional production can arrange the various system module components of extrusion molding equipment to produce fixed points even Global procurement is very beneficial to ensure quality throughout the period, reduce costs, and accelerate cash flow.
Intelligent and networked: foam pelletizers in developed countries have adopted modern electronic and computer control technologies. Process parameters such as melt pressure and temperature, temperature of each section, main screw and feed screw for the entire extrusion process are widely used. Speed, feeding amount, ratio of various raw materials, current and voltage of the motor and other parameters are detected online, and closed-loop control of the microcomputer is adopted. Some companies have adopted online remote monitoring, diagnosis, and control to perform network control of extrusion molding lines. This is extremely advantageous for ensuring the stability of the process conditions and improving the accuracy of the product.
With the release of constraints in all aspects in the future, it is not difficult to find that the prospects for the development of recycled plastics are considerable. Foam granulators have become the market leader. With the introduction of the national policy and the support of the government, the development of the foam granulator industry has accelerated and it has reached the peak of the industry.
From consumer, business, policy and other levels, the demand for recycled plastics is constantly increasing, and the market share of foam pellet machines is getting heavier and heavier, and its overall development is expected to achieve breakthroughs in the near future. In recent years, due to large-scale, precision and high-speed equipment, domestic products still have many deficiencies. In recent years, the number of plastic machinery imported by China has also been growing rapidly. In particular, people’s awareness of recycling is increasing, so they take foam. Granulators are still in short supply.
