Çin plastik ekstruderinin geleceği

Özet

In China’s plastic machinery market, China plastic extruder, as an important processing equipment, has a very optimistic development prospect. In the past two years, my country’s plastic extruder market has made a lot of progress and breakthroughs, which is reflected in the increased development of emerging markets for extruders, the further expansion of brand awareness, the further improvement of market competitiveness, and the proportion of exports to emerging countries. will be greatly improved.

At present, in China plastic extruder equipment, the plastic extruder is usually called the main machine. After a century of development, the extruder has been derived from the original single screw to twin-screw, multi-screw, and even no-screw models. The plastic extruder can be matched with various plastic forming auxiliary machines such as pipe, film, holding material, monofilament, flat wire, packing tape, extruded mesh, plate (sheet) material, profiled material, granulation, cable coating, etc. Various plastic extrusion molding production lines, producing various plastic products. Based on its excellent performance, plastic extruders have been widely used, and its future development prospects are also optimistic in the industry.

"Three" Trends of China Plastic Extruder’s Future Development

1. Development in the direction of large-scale, high-speed and high-efficiency

Foreign extruders with screw diameters of 200-250mm are very common, and special extruders with screw diameters greater than 400mm are not uncommon. Increasing the screw diameter can improve the production capacity of the extruder. When the screw diameter is doubled, the production capacity of the extruder can be increased several times.

High-speed and ultra-high-speed extruders with a speed of more than 300r/min appear abroad, which greatly improves the production capacity of the extruder. However, after the rotation speed is increased, it will bring problems such as poor plasticization, which leads to the emergence of many new types of screws, such as separation type, mixing type, barrier type, split type, combination type, etc. The length-diameter ratio of the screw has also developed from 20:1 to 36:1, and some are as high as 43:1.

2. Modular

The auxiliary equipment of China plastic extruder has also been perfected and standardized to meet the requirements of different plastic products. Modular production can adapt to the special requirements of different users, shorten the research and development cycle of new products, and strive for a larger market share. Specialized production can arrange fixed-point production or even global procurement of various system module components of extrusion molding equipment, which is very beneficial to ensuring the quality of the whole period, reducing costs, and accelerating capital turnover.

3. Intelligence and networking

Extruders in developed countries have generally adopted modern electronic and computer control technology. The ratio of raw materials, the current and voltage of the motor and other parameters are detected online, and closed-loop control by microcomputer is adopted. Some companies have adopted online remote monitoring, diagnosis and control to control the extrusion molding production line. This is extremely beneficial to ensure the stability of the process conditions and improve the accuracy of the product.

4. Customization

In order to adapt to the requirements of new materials and new processes, new or special extruders are constantly emerging. Such as three-screw extruder and planetary multi-screw, no-screw extruder, reactive extruder, two-color extruder, foaming extruder, etc.

China plastic extruder response strategy

In the past two years, China’s plastic extruder market has continuously made breakthroughs. After long-term development, the international influence of my country’s plastic machine industry has been continuously improved, the ability to deal with trade protectionism has been enhanced, and the level of manufacturing technology and overall strength has been further improved. Favorable conditions for foreign trade and exports are gradually emerging.

At the same time, China plastic extruder supplier JWELL has developed a wealth of energy-saving solutions from various perspectives to meet the energy-saving needs of users to the greatest extent. Therefore, China plastic extruder industry has many favorable conditions in terms of foreign trade export.

At present, various plastic extrusion technologies have been used in all aspects of the industry, from the improvement of the screw structure of the extruder itself, to the application of new drive motors, and even the application of various new heating technologies, all of which are promoting extrusion technology toward More efficient, energy-saving and high-yield development. With the promotion of the market, the industry presents three characteristics.

• The industry pays more and more attention to high-efficiency and energy-saving technologies, and energy-saving, high-efficiency and high-yield extruders have become an important direction of technological innovation.

• The demand for high-performance flexible packaging films in industrial fields such as food, beverage, and new energy continues to rise, which promotes the continuous innovation of multi-layer co-extrusion technology of plastic films.

• China’s extrusion technology has begun to increase research and development efforts in the fields of various supporting parts and auxiliary equipment, and the pace of application and expansion of new technologies has accelerated, promoting the rapid improvement of the overall technical level.

Since China plastic extruder products are closely related to strategic new industries, they have the advantages of high efficiency, energy saving and high cost performance, and their exports to developed countries are mainly low-end and middle-end, and this part of the consumer demand is rigid. Therefore, as a China Plastic Extruder manufacturer, JWELL will have broad market prospects in the plastic machinery industry. At the same time, we also need to see the challenges we face!
