With the promotion of the global “double carbon” goal, green low-carbon has become the core theme of the development of various industries, manufacturing industry as the focus of energy consumption and emissions, green transformation is imminent. Mould manufacturing as a basic link in the manufacturing industry, the traditional production model exists in high energy consumption, waste, pollution, low utilization of resources and other issues, such as mold processing steel waste, cutting fluid pollution, equipment, high energy consumption, waste mold waste disposal, etc., not only does not meet the requirements of environmental policy, but also increase the cost of enterprise production. In the policy constraints and market-oriented dual drive, green manufacturing, low-carbon production has become a new trend in the mold manufacturing industry, take the road of green and low-carbon, sustainable development, become a mold enterprise transformation and upgrading of the inevitable choice.
Green low-carbon transformation of the mold manufacturing industry, the core is from the design, production, materials, operation and maintenance to the recycling of the whole process, practicing energy saving, consumption reduction, pollution reduction, recycling concepts, to achieve a win-win situation of economic and environmental benefits. First of all, green design is the source, from the stage of mold research and development into the low-carbon concept, maximize the utilization of resources, reduce production losses. In the mold structure design, the use of lightweight, compact design, optimize the layout of the mold cavity, reduce the use of mold steel; promote the design of a multi-cavity mold, increase the number of products molded in a single run, improve production efficiency, reduce energy consumption per unit of product and consumables; at the same time, the use of standardized, modular design, improve the versatility of the mold parts and components for easy maintenance, replacement and reuse, to extend the overall life of the mold. At the same time, adopting standardized and modularized design improves the versatility of mold parts, facilitates maintenance, replacement and reuse, and prolongs the overall service life of the mold. Through green design, we can reduce the consumption of raw materials and energy consumption from the source, and reduce the pressure of environmental protection in the subsequent production process.
Green production process and energy-saving equipment, is the core link of low-carbon transformation of mold manufacturing. Traditional mold processing equipment with high energy consumption, low efficiency, cutting fluid, lubricants and other consumables used, easy to cause environmental pollution, and processing steel waste, metal dust is more, a serious waste of resources. Green production model, the enterprise gradually eliminated high energy consumption, high pollution of the old equipment, the introduction of high-speed, high efficiency, low energy consumption of CNC machining centers, intelligent machining equipment, this type of equipment, high processing efficiency, low energy consumption, can significantly shorten the processing time, reduce the unit of product energy consumption; the use of dry machining, micro-lubrication processing and other green technology, reduce the use of cutting fluid and emissions to avoid the waste of liquid pollution, and at the same time to reduce the consumables Optimize the processing route, reduce repeated processing and waste generation, classify and recycle the steel waste and metal chips in the processing process, and hand them over to professional institutions for recycling, so as to enhance the recycling rate of resources.
The selection of environmentally friendly materials and the promotion of mold remanufacturing technology is an important support for the green development of the mold industry. In terms of mold materials, the gradual elimination of high-pollution, high-energy consumption of poor quality mold steel, the selection of recyclable, high-performance, long-life environmental protection mold materials, such as recycled mold steel, powder metallurgy environmentally friendly steel, this type of material production of low energy consumption, recycling, in line with the requirements of the green environmental protection. At the same time, vigorously promote the mold remanufacturing technology, mold remanufacturing refers to the waste mold repair, refurbishment, upgrading, so that it restores or even exceeds the performance of the original mold, compared with the brand new production molds, remanufacturing molds can save more than 60% raw materials and energy consumption, reduce the production cost of about 50%, is an effective way of achieving low-carbon cycle. For the wear and tear, damaged scrap mold, professional and technical personnel through the surface repair, cavity modification, parts replacement and other processes to complete the remanufacturing of molds, so that it is put back into use, not only to reduce the environmental pollution caused by the waste of scrap molds, but also reduce the cost of the enterprise mold procurement.
The deep integration of digital, intelligent technology and green manufacturing empowers and enhances the low-carbon transformation of the mold industry. Through the MES production management system, accurate scheduling of production plans, optimize the operating parameters of the equipment to avoid idling, idle equipment caused by the waste of energy consumption; the use of big data analysis of production energy consumption data, locating high-energy links, targeted optimization of the production process and equipment parameters, to achieve accurate management and control of energy consumption; intelligent monitoring system real-time monitoring of the workshop exhaust gas, waste liquids, dust emissions to ensure that the pollutants meet the standards and avoid environmental pollution. Avoid environmental pollution. At the same time, the digital simulation technology can reduce the number of mold trials, avoiding the waste of raw materials, energy consumption and consumables in the process of mold trial, and further realize the reduction of consumption and carbon reduction.
Policy support and industry self-regulation, is to promote the green transformation of the mold industry is an important guarantee. In recent years, the state has introduced a number of policies to encourage the green and low-carbon development of the manufacturing industry, the high-end mold green manufacturing included in the key areas of support for energy-saving transformation of enterprises, environmental protection equipment purchases, remanufacturing technology research and development to give subsidies and tax incentives. Mold industry associations also actively promote the development of green standards, guide enterprises to establish a green development concept, to carry out green factories, green mold product certification, to create a green development of the industry atmosphere. For mold enterprises, green transformation is not only a response to policy requirements, but also to reduce production costs, enhance corporate image, enhance market competitiveness of the important initiatives, more and more downstream customers in the selection of mold suppliers, will be green, low-carbon production as an important assessment criteria.
Green low-carbon mold manufacturing industry is the inevitable requirements of high-quality development, but also an important track of the future competition in the industry. Mold companies want to achieve long-term development, we must abandon the traditional crude production model, the green concept into the whole process of business operations, from green design, green production, material selection, recycling and other aspects of the force, and continue to promote energy saving, pollution reduction and efficiency. In the future, with the continuous innovation and popularization of green technology, mold manufacturing industry will gradually achieve low energy consumption, low pollution, high utilization rate of sustainable development, both to protect the ecological environment, but also to promote the industry's healthy and steady progress, helping the entire manufacturing industry to achieve the goal of green low-carbon transformation.
