In the plastic machinery market in China, the extruder is an important processing equipment and the development prospects are very optimistic. In the past two years, China's plastic extruder market has made significant advances and breakthroughs. Its performance has been to increase the development of new markets for extruders, further expand brand awareness, further increase market competitiveness, and increase the proportion of exports to emerging countries. It will also greatly improve.
Although the extruder market in China has developed rapidly, the export ratio of extruders remains low. The rising cost of raw materials and the pressure on energy costs have made energy-saving and material-saving the focus of the extrusion and processing industry. At the same time, extrusion technology suppliers are able to develop a variety of energy-saving solutions from a variety of perspectives in order to best meet the energy-saving needs of users.
China's plastic machinery adjustment structure enhances the development space of the extruder industry. At present, the status quo of the domestic plastics machinery industry is the existence of the problems of low independent innovation capability, high-end and personalized special varieties, and low industry concentration. The existence of these problems led to China's plastic machinery industry can not catch up with foreign plastic machinery as soon as possible.
After long-term development, the international influence of China's presses industry has continuously improved, and its ability to respond to trade protectionism has been enhanced, and its manufacturing technology and overall strength have been further enhanced. Therefore, there are many favorable conditions for China's extruder industry in export trade. As China's extruder products are closely linked with strategic new industries, they have the advantages of high efficiency, energy saving, and high cost performance. The exports to developed countries are mainly in the low-end market. This part of the consumer demand is rigid, and therefore, the extruder The development of the industry still has a large market space.
Domestically, China is still in an advanced stage of industrialization, informatization, urbanization, marketization, and internationalization, and it is still in an important period of strategic opportunities for development. This will also provide an inexhaustible driving force for the development of the extruder industry. Finally, the warming of the international market has brought confidence to the extruder companies.
China's plastic extruder industry has great potential for development
At present, China's plastics machinery industry is undergoing changes in the global market structure, which is highlighted by the sharp decline in imported equipment. Of course, the decline in imports does not mean that the use of foreign equipment is declining because most of the brand manufacturers have moved production to China; Exports are also slowing down, especially after the rapid growth in 2012. The overall slowdown in 2013 was evident.
In October, 179 extruders were imported, the import amount was 66.79 million U.S. dollars, and imports increased by 61.3% year-on-year. Of course, such a large increase was mainly due to the continuous decline in extruder imports from October last year. The overall decline in imports was relatively large. October was the first increase in imports in the second half of the year. In addition, the export of extruders also declined overall this year. In October, 818 export extruders were exported with a value of 25.574 million US dollars, a year-on-year decrease of 12.3%. From the overall perspective of this year, compared to the sharp increase in 2012, the top 10 of the year Monthly extruder exports fell 7.3%.
Although China's exports to Thailand's injection molding machines have fallen sharply this year, there seems to be signs of recovery. In fact, the extruder also has a trend of increasing demand. From January to October this year, Thailand imported a total of 413 extruders from China, with an export value of 2220. Ten thousand US dollars, an increase of 39.7% compared to 15.878 million U.S. dollars in the same period of last year, despite the fact that last year was a year in which plastics machines in Thailand were heavily replaced. It is also worth mentioning that the export unit has always been cheaper to export, but Thailand's unit price also exceeded 50,000 US dollars this year to reach 54,000 US dollars.
In addition, although Russia’s export extruders fell sharply in October, Russia is still the largest importer of the country’s extruders. The amount of imports in October was 1.656 million U.S. dollars, accounting for 6% of China's total export volume of extruders, which is equivalent to Thailand.
In short, in terms of the current global pattern of presses, there are several main characteristics: First, imports are decreasing; Second, export growth is slowing down; Third, the unit price of exports is increasing.
Extruder originated in the 18th century. Since its development, technology has also been continuously upgraded. At this year's K Show, Reifenhuser has exhibited a 2020 extruder prototype with the theme of "Rethinking".
One of the future studies is the introduction of the innovative plasticization concept Energizer, which minimizes the energy input and most of the cylinder does not require cooling. With Energizer, the melt temperature can be reduced by 20°C with the same yield and melt quality.
In this future concept extruder, Reifenhuser Extrusion Technologies places special emphasis on energy, power, reliability, maintenance, operation, design and functionality. How far are these concepts from us? Bringing together all these concepts and eventually achieving economical commercialization, Reifenhuser believes it will take six years.
By cooperating with Siemens, Extrusion Technology has specifically demonstrated that it is free to select the extrusion drive concept of the motor. Without additional engineering investment, customers can freely choose the required motor protection level and cooling method. This technology is expected to enter the market in 2015. Another promising application is the cooling and target heating applications of Peltier elements in slotted sleeves.
The efficiency of plastic extruders 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 expanded 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.
Extrusion machines in developed countries nowadays have generally adopted modern electronic and computer control technologies. Process parameters such as melt pressure and temperature, various body temperatures, main and feed screw speeds, and feed rates for the entire extrusion process , The ratio of various raw materials, the current and voltage of the motor and other parameters are detected online, and the 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.
