Plastic extruder development space upgrade China's plastic machinery enterprises in recent years increased the development of the emerging market for extruders, brand awareness is further expanded, market competitiveness is further improved, and the proportion of exports to emerging countries will also be greatly improved. At present, orders for plastic extruders in China have rebounded sharply, and export growth has steadily progressed.
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 has led to China's plastic machinery industry can not catch up with foreign plastic machinery as soon as possible, after a long period of development, the international influence of China's presses industry continues to increase, to strengthen trade protectionism, manufacturing technology and overall strength To further improve, therefore, China's extruder industry has a lot of favorable conditions for export.
As the economy picks up, extruder orders will pick up substantially. In 2012, a number of positive signals have emerged in the economic operation of China's extruder industry. However, one of the concerns worthy of enterprises is: 1. The growth rate of the production and sales of automobiles with the largest weight in the total industrial output is constantly rising; 2. The key enterprises in the machinery industry Accumulated orders appear to have warmed up.
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. Finally, people in the industry stated that in recent years, the market for plastics machinery enterprises in China will be further expanded, and the popularity will be further expanded, and the competitiveness of the market will be further enhanced. The proportion of exports to emerging countries will also be greatly increased.
On the whole, the export growth of China's extruder products will show steady progress. 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.
In recent years, China's conventional extruders and production lines have gradually become popular in international markets with excellent price/performance ratio. At the same time, China continues to innovate in the field of advanced extrusion technology and has pioneered a variety of new extrusion products.
Precision extrusion technology to meet the needs of high-precision machining precision extrusion molding can eliminate the follow-up processing methods to better meet the needs of product applications, while achieving the purpose of reducing material costs and improving product quality. Today, to meet the needs of precision direct extrusion of plastic products, a variety of mature technologies have been promoted to the field. Polymer melt gear pumps are one of the important means. This technology has been widely used in chemical fiber, film, profiles, tubes, plates, cables, composite extrusion, granulation and other production lines.
After many years of systematic research on the melt gear pump, the Institute of Rubber and Plastic Machinery of Beijing University of Chemical Technology has successfully completed the series development and development of plastic melt gear pumps. Now it has been able to design and manufacture plastic melt gear pumps such as 28/28 (center Distance/tooth width), 56/56, 70/70, 90/90, etc. The maximum inlet/outlet pressure difference can reach 30MPa, which can meet the requirements of different production, and has been applied in practice to achieve good results. The Institute of Rubber and Plastic Machinery of Beijing University of Chemical Technology conducted an in-depth study of the integrated gear pump extruder and designed and developed a 115-type gear pump extruder.
Gear pumps are also very useful for precision molding in the rubber industry. In order to meet the domestic demand for rubber melt gear pumps, Beijing University of Chemical Technology cooperates with Beijing Aviation Manufacturing Engineering Research Institute and Hangzhou Chaoyang Rubber Co., Ltd. to jointly develop and develop XCP150/100 and XCP120/90 rubber melt gear pumping models. The crew. This unit has ideal working characteristics to ensure a linear relationship between the extrusion volume and the rotational speed of the gear pump, which can achieve precise control of the output and improve the dimensional accuracy of the product.
A project crane is a dedicated crane for all kinds of project construction. The most commonly seen project crane is Gantry Crane. A project gantry crane can be used for road, bridge construction, metro construction, shipbuilding, tunnel construction, power plant construction and other project construction.
The gantry structure can be box type girder and truss type girder with light weight, small wheel pressure and reliable performance. Project crane is mainly made of steel splicing, which can be Single Girder Gantry Crane and Double Girder Gantry Crane. The hoisting mechanism cane be a hoist or a hoisting trolley. The lifting and running speed are slow, and the cost is low, which is suitable for construction.
