The support of policies is a favorable guarantee for the development of recycled plastic granulators. In addition, the advantages of recycled plastic granulators make it possible. Continue to develop.

At present, the recycling rate of waste plastics in China is not high, and there are not many waste plastic recycling factories, especially the uneven distribution. Most of the places are almost blank. On the other hand, in recent years, China has developed rapidly and the market is prosperous. There are dozens of large plastics markets. Waste plastic pellets have been in short supply, and prices have risen and then risen. Therefore, waste plastic pellet processing will become a hot spot for future development. As a main processing machine, recycled plastic pelletizers will have a large customer base.

The plastic recycling granulator processes the waste plastics of daily life to regenerate the plastic raw materials required by the company. The price of recycling waste plastics is far cheaper than the price of plastic raw materials that have been rising in recent years. With the support of the state, it is recycled. The new type of plastic granulator is continuously optimized and updated to achieve full, firm and smooth plastic recycled material. Therefore, it will be favored by more and more businesses.

Since the establishment of recycled plastic pellets is less risky, the scale of investment can be large, and the entrance is low, you can start from one production line, or you can purchase multiple sets of equipment at the same time. But the profits are higher, so there will be more factories in the future, which is undoubtedly a huge business opportunity for recycled plastic granulator equipment manufacturers.

However, in the face of severe energy and environmental challenges, China has recently adopted a comprehensive, coordinated and sustainable scientific development concept as the guiding ideology, and formulated a medium and long-term energy science and technology development strategy and development plan to 2020. This energy environment development strategy The formulation also pointed out the direction for the development of China's plastic granulator technology, and it is imperative to explore the new development path of plastic granulator technology.

Efficient and multifunctional

The efficiency of plastic machinery is mainly reflected in high output, low energy consumption and low manufacturing cost. In terms of functions, screw extruders have been used not only for extrusion molding and mixing of polymer materials, but also for applications such as food, feed, electrodes, explosives, building materials, packaging, pulp, and ceramics. In addition, the "one-step extrusion process" in which the kneading granulation and the extrusion molding process are combined into one is also worthy of attention.

Large size and precision

The realization of large-scale plastic machinery and equipment can reduce production costs, which is more obvious in large-scale twin-screw foam granulators, blown film units, and pipe extrusion units. The precision can improve the gold content of the product. For example, multi-layer co-extruded composite film needs precision extrusion, and as an important means to achieve precision extrusion, the melt gear pump must be intensively developed and researched.

Modular and specialized

Modular production can adapt to the special requirements of different users, shorten the development cycle of new products, and strive for a larger market share; and specialized production can arrange the various system module components of extrusion molding equipment to be fixed-point production or even global procurement. It is very beneficial to guarantee the quality of the whole period, reduce costs and accelerate capital turnover.

Intelligent and networked

Foam granulators in developed countries have generally adopted modern electronic and computer control technology, process parameters for the entire extrusion process such as melt pressure and temperature, body temperature, main screw and feed screw speed, feed amount, The parameters of various raw materials, the current and voltage of the motor are measured online, and the closed-loop control of the microcomputer is adopted. Some companies have adopted online remote monitoring, diagnosis and control to network control the extrusion molding line. This is extremely advantageous for ensuring the stability of the process conditions and improving the accuracy of the product.

As the supply and demand of PS foam particles in China are very unbalanced, the supply is far less than the demand, so the price of PS foam particles has been rising continuously, it has reached about 10,000 yuan, and the profit has reached 3,000 yuan. The huge demand for equipment production lines, such a huge demand, has created a fiery development of the foam granulator production line. Now there are many customers investing in the foam granulator production line. After the investment construction is completed, after a series of processing and production, Let the foam granulator industry develop better.

Plastic granulator refers to a unit that adds different additives to the resin according to different purposes, and is heated, kneaded and extruded to make the resin raw material into a granular product suitable for secondary processing. The plastic granulator is widely used in petroleum. Petrochemical industry. There are two large granulator manufacturers in the world, one in Japan and one in Germany. The Japanese Kobe Steel Company has a very high market share in the Chinese market.

According to a survey by the US Industrial Market Research Corporation, demand for plastic granulation machinery in the US and Japan will re-emerge in signs of recovery, and demand in Western Europe will accelerate in 2009. Prospects for sales of plastic machinery in China, India and Russia are promising. Demand for plastic machinery will also increase gradually in Turkey, the Czech Republic, Iran and other developing countries and regions. The global construction market continues to evolve in terms of the global market landscape. It will drive demand for extruded products such as plastic pipes and siding, which will drive demand for extrusion equipment. Therefore, it is expected that the global demand for extrusion equipment will exceed that of other types of press products.

Among them, the German granulator industry ranks first in the world. Looking back at 2008, the total import volume of granulators was US$5.46 billion. The total amount of imports accounts for more than 20% of the world's total imports, and the global granulator competition is in a dominant position. Italy and Japan are ranked second and third.
