Technically reliable, environmentally friendly and clean is the need for fastener development

In the past 10 years, the rapid development of China's fastener industry has made China a part of the world's factories. It can be said that the world's most famous traders have found their OEMs through China, but due to the extensive operation of most fastener companies, energy and environmental issues are getting more and more attention.

Fastener enterprises should pay attention to technological transformation, continuously improve the level of fastener manufacturing, save energy, protect the environment, and take the road of sustainable development.

1. Technological advancement

The technology of fastener manufacturing involves a wide range of surfaces. At present, the formation of domestic fastener products is mainly in the two categories of "thermoforming + (auxiliary cutting) + thread processing" and "cold molding + (auxiliary cutting) + thread processing". Automatic forming cold heading is the main production method.

The biggest difference between domestic and foreign is that the precision of the equipment used is different, the control level, additional function efficiency, reliability, etc., many companies have purchased multi-function bolts and nut cold heading machines, from four-mode four-rush to six-mode six-rush Cold heading machine, relatively high price, but value for money. The manufacture of shaped parts and high-precision parts does reflect the improvement of the technical level.

After the automatic multi-function cold heading machine has become the mainstream equipment of the global fastener industry, a new round of equipment innovation at home and abroad is bound to be in the pipeline or a new equipment update will arrive at some time.

The cleanliness of finished fasteners is an important project. Finished products other than electroplated fasteners must be clean and clean, fully utilize ultrasonic cleaning, aqueous solution cleaning, complete the cleaning of fastener products, and then transfer to blackening, phosphating, and oiling.

2. Less pollution free emissions

The state has put forward higher and stricter requirements for environmental protection and emissions of enterprise production. The drawing process must consider renovating and renovating the old equipment, and at the same time increase investment in purchasing high-tech equipment without pollution, improving production and surrounding environment. The phosphorus saponification liquid is recycled, and the waste acid liquid is collected to reduce or avoid the emission of harmful gases and create a green production environment.

3. Production process control is stable and reliable
The whole process system control is performed on the cold forming process, the heat treatment quenching and tempering, and the carburizing process. Due to the high efficiency of the cold heading machine and the large production capacity of the continuous belt belt furnace, the special automatic inspection equipment is used to sort out the irregularity, cracking, product miscellaneous and unqualified products, which not only can guarantee the quality of the finished product, but also save manpower and material resources. To simplify the subsequent surface treatment, the comprehensive economic benefits are very obvious.

4. Equipment maintenance
In the fastener manufacturing process, the stability and reliability of the equipment is an important condition to ensure the stability of the product quality. At present, there are many manufacturers of cold heading machines and continuous belt belt furnaces at home and abroad, and important components are selected and manufactured according to their respective standards, which brings a lot of inconvenience to the maintenance and maintenance of users. In order to provide convenience to users and promote the promotion and application of high-tech and high-efficiency equipment, it is recommended that equipment manufacturers establish spare parts warehouses in various places (main fastener production bases) to provide rapid technical support and guarantees to reduce users' worries.

Since July 1, the export tax rebate rate for fastener products has been reduced from 13% to 5%. For fastener companies with very limited added value, firstly, improve the manufacturing quality and reduce the cost of tooling. Secondly, reduce The cost of producing excipients increases the added value of the product “open source and thrifty”. It can be seen that the fastener equipment is technically reliable, and environmental protection and cleanliness is the first priority, especially in terms of energy saving and economical operation cost. To this end, in the context of building a conservation-oriented society, fastener companies should invest in a new round of equipment technology climax.
