Three plastic machinery into industry important support

HC plastic mesh News: four tied with steel, wood, cement foundation material of plastic polymer material. Plastic products have also been widely used in various sectors of the national economy and people's lives in all areas. International Mould & Metal & Plastic Industry Suppliers Association official Luo Baihui, all plastic raw materials shall be subject to the manufacture of plastic machinery and mold to molding uses a wide range of plastic products, plastic machinery has become the aerospace, defense, petrochemical important support, marine, electronics, optoelectronics, communications, building materials, packaging, electronics, automotive and transportation, agriculture and light industry of the national economy.
In recent years, plastic machinery industry to industry to upgrade the main line, adhere to independent innovation, energy saving and environmental protection, high-end development path, accelerate research cooperation, have been developed and produced a large number of highly efficient energy-saving plastic machinery products. For example, the industry launched servo energy-saving plastic injection molding machine, according to the article geometry, product size, to achieve energy saving rate of 40% to 80%, the energy-saving effect reached the international advanced level, recognized and welcomed by the market.

"With the growing demand for plastic, plastic machinery industry market has great potential." International Mould & Metal & Plastic Industry Suppliers Association official Luo Baihui that, from a global perspective, the three categories of the plastic machinery varieties turn injection molding machine, extruder / extrusion lines and blow molding machines, and they account for more than 80% of the total output value of plastic machinery, injection molding machines accounted for more than half of the total of these three types of mechanical.

First, the injection molding machine

The injection molding machine is the molten plastic is injected into the mold after cooling products. Uses a very wide range of different plastics used is also different. The injection molding machine is used in the plastics processing industry the largest processing machinery, not only a large number of products are available direct production of injection molding machines, and it is composed of key equipment injection stretch blow process.

The injection molding machine control system features:

A famous factory advanced computer control;

Self-diagnosis fault function;

3. Direct input pressure, speed, time, trip, and temperature data;

4.LCD color LCD display

5 centralized lubrication;

6. Pressure the coupling oil line to save power;

7.24 VDC hydraulic directional valve coil never damaged;

8 mold cooling water regulating means;

Electric control of 9.M.C.B. insurance;

10 advanced computer control system, large screen display, operation interface clean and easy-to-use, tube;

11 high-precision electronic ruler stroke control accuracy of up to ± 0.1mm;

12 by using a pressure, fuel feedback to improve the reproducibility;

13. Mechanical, electrical, hydraulic safety device, any circumstances to ensure the security of the operation (PD60-PD148 optional hydraulic);

14 by installing a superior position sensor to improve the reproducibility and operability;

15 using a closed-loop control of the control to achieve ultra-precision molding.

Second extruder

Extruder is the screw under the action of the molten plastic through the fixed shape of the extrusion exit extrusion, cutting the effect of the traction machine, after water-cooling setting. Mainly used for a variety of products of the same cross-section continued production, such as tubes, rods, profiles, etc., but also can be used for plastic modified granulation.

Extrusion of the basic mechanism is simple - a screw in the cylinder rotation and put the plastic to move forward. The screw is actually a ramp or slope, is wound on the center layer. Its purpose is to increase the pressure in order to overcome the large resistance. One extruder, there are three kinds of resistance to be overcome: the solid particles (feed) of the friction and the screw on the wall of the cylinder to rotate the front laps (feed zone) the mutual friction between them; melt melt is pushed forward when the internal logistics in the adhesion of the cylinder wall; resistance.

According to the International Mould & Metal & Plastic Industry Suppliers Association official Luo Baihui observed, the demand of the market for high-tech injection molding machine will gradually strengthen. First all-electric hydraulic precision injection molding machine, its main market of electronic communications, home appliances, automobiles, and other requirements of the processing conditions also improved the precision requirements of the injection molding machine; hollow injection molding machine, a variety of rubber and plastic materials combined application plus the hollow injection technology, which can effectively improve the plastic parts in a state of vibration stress damage problem; Third, the new injection molding machines with air-assisted water assistive devices, such technology has a lot of recent market, especially higher requirements to the appearance of long-lived products, such as home appliances, automobiles, construction, and other more attractive.

Third, the blow molding machine

The blow is a common method for manufacturing hollow thermoplastic products, the main product is a tube membrane and hollow container. Blow molding machine preform is plasticized by heating, and then into the mold, Blow molding, this method is mainly used for high-speed high-yield production of PET bottles and BOPP bottle, a two-step process; blow with combination of injection molding process injection stretch blow one machine, which is commonly used method for the production of PET container; combination of the blow molding process can be used with the extrusion process, to adapt to a wider range of extrusion blow molding equipment, capable of producing more products rich, including multi-layer composite films and all kinds of polyolefin hollow container products, widely used in food, pharmaceutical and cosmetics industries.

Lower prices blow molding equipment, low energy consumption, adaptability, it make up for the shortcomings of injection molding, molding of industrial parts with a high degree of integrity, good overall performance, high added value, and lower cost. " International Mould & Metal & Plastic Industry Suppliers Association official Luo Baihui that, blow molding machinery lowest proportion in the three presses, but the future will be to maintain the strong momentum of development, is the fastest growing and the most potential for development models.
