The hottest precision has become the pursuit goal

Precision has become the pursuit goal of the plastic extruder industry

with the increasingly high requirements of modern social industries for products, precision has become the pursuit goal of the plastic extruder industry. Starting from the process, we should strengthen the research and development breakthrough of the precision performance of products, update the extruder products, pay attention to the computer control of the machine, and continue to research and develop in intelligent and automatic performance, so that the extruder can regain a good momentum in export

to realize the precision of extruder can improve the gold content of products, such as multi-layer coextrusion composite film, which requires precision extrusion. As an important means to realize precision extrusion, the application of melt gear pump must be strengthened for development and research

with the development of plastic processing machinery industry, China's extruder industry has flourished, and now it can meet the basic needs of the domestic market. On the premise of continuously improving product performance and quality, it has maintained a good trend in exports. Since the first half of this year, the export of extruder products has fluctuated, and the overall export amount of the industry has decreased slightly

judging from the export amount of each month in 2013, the export amount of each month except March is 0 Fluctuated between us $300 million, of which the export amount in January and may was the highest, reaching US $30 million, and fell to US $17 million in March. In 2013, the overcapacity crisis was the most serious at the beginning of the year, and manufacturers took price reduction measures to maintain profitability, resulting in a sharp decline in the export amount of extruders in March; With the gradual weakening of the impact of the financial crisis on the world economy, the warming of the international market situation, and the measures taken by various production enterprises to reduce production capacity and stabilize prices, the international market demand gradually increased, the domestic machinery price tended to normalize, and the export amount of extruders gradually rebounded

compared with the same period last year, the export amount of each month changed significantly. On the whole, Extruder "In terms of China's new materials, the export amount of Ningbo is lower than that of the same period last year, with a significant downward trend, and the export amount in the first half of this year is not very optimistic. The optimization and upgrading of the industrial structure has continuously improved the requirements of the domestic and foreign markets for the precision of extruder products. Whether the precision production of extruders can be achieved and a breakthrough can be made in the multi-layer coextrusion performance has become the key to win the market competition.

at present, extruders in developed countries have become popular Modern electronic and computer control technology is used to monitor the process parameters of the whole extrusion process, such as melt pressure and temperature, body temperature of each section, rotating speed of main screw and feeding screw, feeding volume, ratio of various raw materials, current and voltage of motor, and microcomputer closed-loop control is adopted. Some companies have adopted remote monitoring, diagnosis and the situation control of rapid growth in the domestic takeaway market in 2016, which is extremely beneficial to ensuring the stability of process conditions and improving the accuracy of products
