Analyzing Development Trend of Plastic Machinery
In recent years, plastic machinery industry is to upgrade the main line, adhering to independent innovation, saving energy and environmental protection, high-end development path, accelerating research cooperation. Now plastic machinery industry has been developed and produced a large number of highly efficient energy-saving products. For example, according to the article geometry and product size, the launched [servo energy-saving plastic injection molding machine" achieves energy -saving rate of 40% to 80% which reaches the international advanced level and is recognized and welcomed by the market. Let me introduce main three types of plastic machinery to you.
First, the injection molding machine
The great characteristic is to apply molten plastic injected into the mold. After cooled, it becomes product. The injection molding machine can product directly, it is also important equipment for injection stretch blow process. The injection molding machine control system features: adopting advanced computer control; Self-diagnosis fault function; directly inputting pressure, speed, time, trip, and temperature data; pressure the coupling oil line to save power; mold cooling water regulating means; high-precision electronic ruler stroke control accuracy of up to 0.1mm, etc.
Second, Extruder
The basic mechanism of screw is simple - a screw in the cylinder rotates and puts the plastic to move forward.
Molten plastic is squeeze out by extruder under screw through a fixed shape extrusion then cut after water-cooling setting under the role of the tractor. Extruders are mainly used for the variety of the same cross-section of the products of continuous production, such as tubes, rods, different profiles, etc. and can also be used for plastic modification granulation.
Third, the blow molding machine
The blow is a common method for manufacturing hollow thermoplastic products; the blow can also combine with injection molding process and extrusion process which are capable of producing abundant products widely used in food, pharmaceutical and cosmetics industries.
From a global perspective, three main categories of the plastic machinery is injection molding machine, extruder / extrusion lines and blow molding machines which account for more than 80% of the total output value in plastic machinery fields, International Mould & Metal & Plastic Industry Suppliers Association official Luo Baihui said. Therefore plastic machinery industry market has great potential.
