Commitment to China to the world at the general debate of the 75th session of the United Nations General Assembly

Carbon dioxide emissions strive to peak by 2030, and strive to achieve carbon neutrality (le “double carbon” target) Tuméen 2060. Facing the goal of “double carbon”, the energy-saving improvement of injection molding machine is an imperative way.

Energy consumption analysis of injection molding machine

By the injection molding process, the molten polymer solvent is injected into the mold cavity. After the polymer solvent is cured, the mold cavity is opened and the plastic parts are pushed out. Specific action: move the injection seat forward to the injection pressure cooling (preplastic), the injection holder back to move the roof of the top reset mold.

In wéet k'iin, it is also necessary to reduce the heating power of the material cylinder and the baking bucket, etc. Through these improvements, the power consumption of injection molding machine is minimized as far as possible.

Improvement of injection molding machine

Bejla'e', the injection molding machine has the application of servo system (including some full electric control), and the industry is gradually carrying out the heating ring and drying hopper supporting [4]. The energy saving benefits is a large amount, but also a measure to reduce emissions. The huge space of the plastic industry has driven the rapid development of the injection molding machine (including extruder) industria, and driven the development and development of energy-saving heating device, energy-saving heating device as plastic machinery.

Secadora plástico (also known as baking bucket) is an essential peripheral equipment in injection molding, which plays an important role in stabilizing the injection molding and surface quality of plastic parts. The working principle of the traditional plastic dryer: the hot air of the internal heating pipe of the fan dryer is blown into the inside of the cone hopper, with the upper and lower sieve and the surface of the hopper as the heating wire in the dryer bucket

Under the action of the fan blowing, the wind blows into the material barrel to achieve the purpose of drying.The traditional dryer has no intelligent detection sensor, can not be intelligent.

Control the dry air volume, is constant air volume operation, more power consumption, low thermal energy conversion rate, serious energy waste and other phenomena.

In order to improve the energy saving of the original baking barrel, the control part of the baking barrel is specially treated intelligently, and the structure of other baking barrels remains unchanged. The digital temperature intelligent control servo automatic system, basically composed of computer programs, can compensate the power required for constant temperature according to the set temperature of the material barrel controller, so as to intelligently control the temperature, air volume and heating power, and achieve the energy saving effect of constant temperature heating of drying material. Energy saving effect between 40%~60%, simple installation, no additional after debuggingmaintenance.200 kg oven barrel power 3.3 kW.h one hour before improvement,

After the improvement, it is 1.5 kW.h, the basic power saving rate is 54%, and the cost can be recovered in 6 Utia'al 10 months. As shown in Figure Figure 22. The first of its energy saving principle is to automatically adjust the power, give the matching power according to the drying degree of the material, maintain the temperature required by the drying material and stabilize the constant temperature to reduce the waste. Segundo, the air volume is automatically adjusted, real-time measurement of the temperature dryness of plastic, through the system automatically control the size of the tuyere, so as to reduce the heat loss. Tercero, eliminate potential safety risks, when the temperature reaches a certain extent, the system will automatically cut off the power supply, play a role in safety protection.

Six CCD cameras can generally be installed.

As an important molding equipment in plastic parts processing, injection molding directly affects the quality of plastic parts. It occupies an important proportion in injection molding processing. Paying attention to the use and maintenance of molds and extending the service life of molds, it is an important issue of energy saving, emission reduction, cost reduction and efficiency increase in injection molding industry.

tagIt is reported that plastic production and incineration are expected to occur in 2019

Asab u 850 million t CO 2 equivalent, equivalent to emissions from 189 500 MW coal-fired power plants. Experts estimate that global plastic production and incineration will emit 56 billion t carbon dioxide equivalent from now to 2050, representing 10 Utia'al 13 percent of the total carbon budget that can be “spent” by the middle of the century based on current emissions reduction commitments. By the end of the century, plastic-related emissions could account for half [18] of the total carbon budget. From these data, the carbon emission of injection molding industry is still very large, in the futureThere is a long way to go to reduce emissions. In wéet k'iin, we need to reduce emissions and apply new energy through technological progress. Bejla'e', the injection molding industry is an important way to reduce emissions by saving electric energy, controlling product quality and producing more qualified products. The implementation of energy saving and emission reduction, cost reduction and efficiency increase is the basis of realizing the “double-carbon” goal. Beey xan, “intelligent manufacturing” should be used to reduce carbon, and provide source power for the intelligent manufacturing upgrading and green transformation. A series of measures will be implemented to reduce emissions and do little to mitigate the global greenhouse effect.
