Five characteristics of the development trend of plastic extrusion mold factory

The current development trend of the mold market is constantly improving, and the pipe extrusion molds have the market is also gradually improving, the comprehensive development trend of the current plastic extrusion mold market, a total of the following five characteristics.

Characteristic one: high speed, high yield extruder high speed, high yield, can make the investor with lower input to obtain larger output and high return. However, high-speed extruder screw speed also brings a series of difficulties that need to be overcome: such as the material in the screw to reduce the residence time will lead to uneven mixing and plasticization of the material, the material is subjected to excessive shear may result in rapid heating and thermal decomposition of the material, extrusion stability control difficulties will cause fluctuations in the geometry of extruded material, the relevant auxiliary devices and control systems must improve the accuracy of the screw and the barrel of the need to intensify the wear and tear. The use of high wear-resistant and ultra-high wear-resistant materials, reducer and bearings in the high-speed operation of how to improve their life and other issues need to be resolved.

Feature 2: high efficiency, multi-functional plastic extrusion molds are mainly reflected in the high output, low energy consumption, low manufacturing costs. In terms of function, screw extruder has not only for polymer materials extrusion molding and mixing processing, its use has been broadened to food, feed, electrode, explosives, building materials, packaging, pulp, ceramics and other fields. In addition, the mixing and granulation and extrusion molding process into one "one-step extrusion process" also deserves attention.

Feature 3: large-scale and precision to achieve extrusion molding equipment, large-scale can reduce production costs, which in the large twin-screw pelletizing units, blown film units, pipe extrusion units, etc. The advantages are more obvious. National key construction services required for major technical equipment, large-scale ethylene projects supporting one of the three key equipment of large extrusion granulator group long-term reliance on imports, so we must accelerate the localization process to meet the needs of the petrochemical industry development. Precision can improve the gold content of the product, such as multi-layer co-extruded composite films and other precision extrusion is required, and as an important means of achieving precision extrusion melt gear pumps must increase efforts to develop research.

Feature 4: modularization and specialization of modular production can be adapted to the special requirements of different users, shorten the research and development cycle of new products, and strive for a larger market share; and specialization of the production of extrusion molding equipment can be arranged for the production of various system modules and components or even global procurement, which is to ensure that the whole period of the quality, reduce costs, accelerate capital turnover are very favorable.

Feature 5: Intelligent and networked extruders in developed countries have been widely used in modern electronic and computer control technology, the entire extrusion process process parameters such as melt pressure and temperature, the temperature of each section of the body, the main screw and feed screw speed, feeding volume, the ratio of various raw materials, the current and voltage of the motor parameters such as online detection, and the use of microcomputer closed-loop control. Some companies have adopted online remote monitoring, diagnosis and control for network control of extrusion molding production line. This is extremely favorable to ensure the stability of process conditions and improve the precision of products.

From the above five points it is easy to see that in the future our mold market will have more room for development.
