Machinery manufacturing is the industry which provides technical equipment for each industry production department. The development of manufacturing industry promotes the development of industry and promotes the construction and development of national economy. Mechanical manufacturing is formed by large-scale exploitation and utilization of natural resources as the basis for the development, this development model has greatly damaged the ecological environment, affecting the sustainable development of the industry, resulting in green manufacturing concept.
Green manufacturing design phase. The first stage of green reflect the application of the mechanical manufacturing process for the design stage in the
product design stage, should fully consider the various environmental problems should be paid attention in the production process, and the energy
conservation and environmental protection as the main design principles. For example, the product material selection, optimization of product structure,
production technology, disassembly and maintenance design, transportation, use and disposal stage, each stage of design should be coordinated, the product manufacture and use of the whole process in energy saving and emission reduction are optimized to realize green production.
Green manufacturing process. Machinery manufacturing in the production process, to achieve the purpose of energy conservation and emission reduction, the need for material selection and strict selection of technology. The choice of materials should be selected for renewable energy, abundant raw materials, low cost and little pollution, energy or material; to avoid the use of radioactive, toxic and harmful materials or energy; technology should be used in dry cutting, low temperature cutting, high precision cold rolling, metal powder injection molding, can edit the NC technology, reduce the energy consumption and reduce material waste, reduce the manufacturing cost of the use of advanced technology, so as to realize the green production process of mechanical manufacturing.
Pollutant treatment of machinery manufacturing. Machinery manufacturing process will produce a large number of waste water, waste residue, waste gas, rough materials, substandard parts and so on, direct waste will not only cause great damage to the environment, but also resulted in the waste of energy and resources. The main methods to deal with above waste, recycling of combustible gas as fuel for reuse, recycling or waste into useful components, the emission of toxic substances into low toxic or non-toxic substances by chemical method, the scrap parts or blank foot material recycling, turning waste into treasure.
