Green manufacturing - Its purpose is to use technical means to optimize manufacturing procedures, reduce environmental pollution, and achieve the purpose of resource conservation and sustainable development.
The basic model of green manufacturing is divided into three aspects, namely green resources, green production, and green products. Among them, green resources refer to the use of green materials and energy in the manufacturing process. From the perspective of raw materials and energy, on the one hand, it can improve energy efficiency. On the other hand, the use of clean energy and environmentally friendly materials can not only guarantee the demand for products but also meet The purpose of environmental protection. Green production includes green design and green production technology. Green design refers to the design of product manufacturing schemes that should follow the concept of environmental protection in the design stage of machinery manufacturing, starting from the perspective of green manufacturing. The green production process includes machinery and equipment using advanced low-energy-consumption technology, green manufacturing process planning, and green production technology. Green products refer to the combination of green concepts in the packaging, transportation, use, and recycling of products to reduce energy consumption and environmental pollution in the later cycle of products.
How to realize "green manufacturing" in mechanical manufacturing?
1. Green design
The proposal of the design plan is the basic stage of the entire machine manufacturing process. The so-called green design refers to the addition of every feasible "green concept" to all aspects of machinery manufacturing on the basis of meeting the original product functional design requirements, whether it is the appearance design of a part of a more in-depth structural design wait, and then convert the plan into a feasible production process through careful analysis and calculation. The "green concept" here refers to the concept of taking environmental protection as a guiding principle, carefully considering the impact of environmental pollution during product processing and manufacturing and after manufacturing, and trying to reduce or even eliminate pollution.
2. Green selection
In each link of machinery manufacturing, the selection of materials has an important impact on the formation and emission of pollutants in the entire production process. Therefore, based on the concept of green production, the selection of raw materials and energy needs to follow three important principles: first, in the selection, we must adhere to diversity and low cost; second, try to ensure the selected materials and energy the usability is strong; third, avoid the selection of toxic materials.
3. Green processing
The green process is the same as the original production process. It uses certain equipment and technology to produce products that meet the requirements according to the mechanical production process and order. The difference is that it must also meet the requirements of saving resources and energy, improving economic efficiency, and reducing pollution. At present, the widely used green processes include dry cutting measures, low temperature cutting measures, high-precision cold grinding measures, metal powder injection molding processes, and the use of programmable controller technology, digital display technology, and data technology to transform old lathes Purify waste liquid, etc.
4. Green pollution
Green treatment refers to the treatment of waste generated in the entire production process, the use of corresponding equipment to realize the pollution-free conversion of pollutants, and the recycling of reusable materials to achieve the purpose of reducing pollution and improving resource utilization.
As the latest product of the modern industry, green manufacturing technology can effectively reduce product input costs and reduce environmental pollution. Green manufacturing will become the key direction of the future development of my country's machinery manufacturing field. When green manufacturing technology is applied to all links of the machinery manufacturing process and throughout the entire life cycle of the product, it is necessary to grasp the impact of each link on the environment and use reasonable methods and scientific technology to deal with it, which can effectively reduce energy. Consumption and environmental pollution to promote the sustainable development of the manufacturing industry while improving product quality.
