Faster production of environmentally friendly fasteners requires government-enterprise cooperation

Since March 1, 2007, when China responded to the EU Environmental Protection Directive and promulgated the "Measures for the Control of Pollution Caused by Electronic Information Products" known as the "China RoHs Directive," both in the international market and in the domestic market, "Made in China" is facing A green threshold. Today, this threshold has continued to increase, and in August 2009, the EU "Environmental Product Design Framework Directive" was fully implemented. This is the EU's "WEEE Directive" and "RoHS Directive" after the launch of the A technical trade barrier.

In the face of barriers, the Chinese fastener industry, which has always won with “more quantity and less price”, has begun to seek a more viable development plan after constantly encountering “Waterloo”. In fact, even if there are no environmental directives, we believe that the future development of China's fastener companies cannot and will not harm the environment. Then, to achieve a coordinated development of fastener companies and environmental protection, where is the road?

The environmental pollution caused by the production of fasteners mainly includes exhaust gas, waste water, dust, fumes (fog) and noise generated and emitted during production. The environmental protection of fasteners requires the cooperation of government and enterprises.

1. Establish a scientific outlook on development. The developed countries in the world put forward the goal of zero energy reduction and zero pollution in machinery manufacturing. Their thinking can be said to be a step ahead and worthy of our study. For a long time, many people in the domestic fastener industry have focused on immediate economic benefits and have been passive about energy saving and emission reduction. Especially under the influence of the idea that "growth is the political achievement and the figure is the truth", in recent years there have been many phenomena of simply pursuing GDP growth in a statistical sense.

To establish a scientific outlook on development, the government should take the lead and increase corporate social responsibility and sense of honor through policy guidance and public welfare publicity. Enterprises should re-examine and evaluate their own business ethics and values, and thoroughly change the past principles of design, production, and operation with the goal of practical performance and short-term economic benefits. As a user of fasteners, it is also necessary to strengthen environmental awareness, and whether or not it meets energy and environmental protection requirements as an important prerequisite for evaluating, selecting, and using fasteners. It must be acknowledged that in the current situation where the concepts, policies and laws and regulations related to environmental protection are not perfect, the constraints of energy and the environment should rely more on the users of high-strength fasteners and even the common supervision and participation of the whole society. .

2. Change the traditional mode of economic growth. Although great achievements have been made in the development of the fastener industry in China in recent years, these achievements are based on the traditional extensive basis, and this growth approach has not yet achieved a fundamental reversal. China's mass production of low-grade, low-cost, low-value-added fastener products has exerted tremendous pressure on resources and the environment. The transformation of the economic growth model to the development of high-end routes is one of the ways in which the domestic fastener industry has crossed the threshold of environmental protection. At present, due to the pull of domestic demand, high-speed rail, aviation, nuclear power and other special areas have strong demand for fasteners, and high-end fasteners are facing tremendous business opportunities. This is the transformation mode of fasteners in China and the development of high-end routes.

3, to develop strengthening measures. In 2007, China responded to EU environmental protection directives and promulgated the "Measures for the Control of Pollution Caused by Electronic Information Products" called the "Chinese RoHs Directive." The RoHS Directive requires that the content of six hazardous substances, ie, lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers, not exceed the maximum limit stipulated in the RoHS Directive, before they enter the European Union. Market passes. China should not always be in a passive position in the formulation of environmental protection directives. It is necessary to formulate some rules in a targeted manner and rigidly require companies to regulate their operations. This is in line with environmental protection and is also a requirement of the rules of the game.

In addition, economic means must also be used. Nowadays, the implementation of ISO 14000 environmental system certification by enterprises is also placed in front of the fastener companies. To protect the environment and conserve resources has become a hot issue. It is imperative to control the fume (fog) pollution in fastening workshops.

4, improve management. Continuously improving the management level of enterprises and comprehensively strengthening management in sales, R&D, production, storage and transportation are fundamental ways to reduce energy consumption and waste pollution. In recent years, ISO9000 series and ISO14001 quality and environmental management system certification work has been widely carried out in the fastener industry, but this is only a few tools and tools related to management, if you leave the advanced management concepts, management structure and perfect The management system cannot adapt to the needs of sustainable development.

In addition, the training and management of employees is one of the effective ways to comply with environmental protection and prevent occupational hazards. Emergency emergency response drills for emergency environmental incidents should be conducted regularly to provide professional training for employees in occupational protection and to improve the emergency disposal capability of environmental protection systems. Warning signs, etc. are set up in the workplace to enable workers to understand occupational hazards, prevention requirements, harmful consequences, and emergency response measures. Enterprise management managers shall take technical and management measures to prevent, eliminate, or reduce harmful factors in their production, operation, and management, such as selecting low-noise cold heading, stamping equipment, adopting basic earthquake protection, installing shock absorbers, and isolating earthquakes; Local ventilation and detoxification device, replacing highly toxic substances with low-toxicity substances in production, cooling measures: remote-control operation, safety cover, safety distance, self-rescue devices (eyes, gas masks) during accidents; In large places, eye-catching safety signs are set, and if necessary, sound, light, or combination alarm devices are set;

5, to strengthen the management of raw materials. First, we need to adjust and improve supply chain management, environmental design, substitutes and processes, testing and certification, and do point, line, and surface integration. The so-called "point" is to control the content of RoHS-instruction-restricted substances in raw materials and components, purchase raw materials that meet the requirements of the RoHS Directive, and send raw materials that are not known to large-scale third-party laboratories that have credibility and qualifications for inspection; It is to solve the material problems in the RoHS directive of fastener surface coating, corrosion protection and electroplating with the green supply chain; “face” is green design, green material, green procurement, green production process, green consumption, green recycling, from the source Compliance with RoHS directive. In the design and development of high-strength fasteners, in addition to considering the requirements of the manufacturing process on the mechanical properties of the product, it must also be based on the selection of raw materials, material restructuring, manufacturing processes, heat treatment, three waste recycling and other aspects Take full account of energy and environmental issues.

6, the rational use of equipment. To adapt to the increasingly high requirements put forward in energy and environmental protection, it is necessary to transform from the following aspects: (1) High-efficiency and energy-saving multi-position combined cold heading equipment; (2) High-precision online nondestructive testing in production And measuring instruments and equipment; (3) using computer systems to track, monitor and control the entire production process; and (4) use waste treatment technologies and equipment that can truly achieve “zero emissions”.

In addition, the service life of cold heading molds is one of the key items in the manufacture of fasteners and is directly related to energy and environmental protection. The service life of cold heading molds actually has two meanings. One is the economically acceptable standard, namely, the so-called life/price ratio; the other is whether the environmental protection is acceptable. At present, under the circumstances that domestic environmental protection laws and regulations are not yet perfect, some products that are unacceptable in terms of environmental protection may be economically acceptable for the time being. However, in the face of increasing environmental protection pressure, this situation will gradually increase. Variety. The longest life of molds achieved from product technology and application technology is still an important direction of efforts.

The environmental protection production of fasteners is a process that involves the whole body and is closely related to each other. Many key factors such as waste liquid treatment, process flow, production technology, and development planning cannot be ignored. The big events in the world must be done in detail. The achievement of a coordinated development of the fastener industry and environmental protection will affect everyone. The cooperation between the government and enterprises will continue without any problems.
