Hardware industry development is on the right track Wan Guan actively participates in standard setting

It is understood that consumer electronics products are mainly vacuum coated on plastic substrates, requiring high bonding strength of the vacuum coating layer and stable and reliable performance. Therefore, the bonding strength of the vacuum coating layer has become one of the important indicators of vacuum coating technology. Vacuum coating product performance and service life.

Guan enterprises won the "standard" again. On September 16th, the “Standard Test Method for Vacuum Technology Bonding Strength of Vacuum Technology” drafted by Dongguan Jinsheng Precision Components Co., Ltd. (hereinafter referred to as “Jinsheng”) was held and is expected to be passed by the end of 2011. Previously, Dongguan enterprises have led the development of a number of international standards, national standards, and local standards.

At present, there is no uniform test method for the strength of vacuum coating layer in China. Under the current technical conditions, the backbone enterprises of vacuum coating production both at home and abroad are referring to and borrowing paint test standards. “It is difficult to be accepted as a norm between customers, vendors, and companies.” Zhang Xuezhang, the person in charge of Jinsheng, said that this has affected the technological progress of the entire industry to a certain extent, and the development of corresponding national standards is a top priority. Once the standard comes out, After that does not mean that the technical threshold will be improved, mainly to improve the technical level of the industry.

The formulation of the "Test Method" national standard was proposed by the State Bureau of Machinery Industry. Jin Sheng was responsible for the drafting. Hefei University of Technology, Shenyang Vacuum Technology Research Institute and other organizations participated in the drafting. Zhang Xuezhang introduced that in September 2009, Jinsheng Co., Ltd. began to prepare for the preparation of the “Test Method”, which is expected to be approved by the end of 2011 and approved by the AQSIQ.

Dongguan enterprises "winning the standard" is now the trend of fire

Prior to Jinsheng, Shengyi Technology became the forerunner in China's development of two IEC international standards for printed circuit products, and it was the first time that Dongguan companies had led the development of international standards.

At the beginning of 2010, two National Standards Examination and Approval Meetings, “Toughened Glass for Furniture” and “Natural Stone for Furniture,” led by the Dongguan Municipal Quality and Technical Supervision Standards and Codes, were convened to finalize the review of the two national standards. The first local standard "Guangdong Provincial LED Street Lamp Local Standard" formulated by Qinshang Optoelectronics Co., Ltd. has been officially implemented last year.

In terms of alliance standards, Dongguan has successively formulated and issued 11 coalition standards including Chang'an metal molds, Hengli plastic molds, and Dao rice flour, and industry alliance standards such as Dao and Humen cables will be released soon.

After working on local standards, Qinshang Optoelectronics became the first company to get a demonstration project of “high-power LED street lights” in Guangdong Province, and obtained the right to install more than 20,000 LED street lamps, which is five times before the establishment of local standards. . In 2013, the output value of vacuum coating-related products will reach 130 billion, and Jinsheng Co., Ltd., as the national standard maker, must have great potential.

Guide Ring

Guide Ring is a mechanical seal, also known as a guide ring. It is usually made of metal or plastic and used to support and position pistons or rods. Guide Ring has excellent wear resistance and corrosion resistance, which can effectively reduce leakage and friction, thereby extending equipment life. Guide Ring is widely used in the hydraulic, pneumatic, mechanical, and automotive industries as an important mechanical seal.


The classification of Guide Ring can be divided by material, structure, and purpose. According to material classification, Guide Rings are mainly divided into metal Guide Rings and plastic Guide Rings. Metal Guide Rings are usually made of metals such as copper, iron, and stainless steel, which have high strength, wear resistance, and high-temperature resistance; The plastic Guide Ring is usually made of polytetrafluoroethylene (PTFE), nylon, polyimide and other materials, with good corrosion resistance and low friction coefficient.


According to structural classification, Guide Rings are mainly divided into unidirectional Guide Rings and bidirectional Guide Rings. A unidirectional guide ring can only withstand pressure in one direction and is typically used in hydraulic and pneumatic systems; The bidirectional guide ring can withstand bidirectional pressure and is typically used in the mechanical and automotive industries.


According to usage classification, Guide Rings are mainly divided into piston Guide Rings and rod Guide Rings. The piston guide ring is usually used to support and position the piston, preventing friction and leakage between the piston and the cylinder liner; The rod guide ring is used to support and position the rod, preventing friction and leakage between the rod and the seal.


In summary, Guide Ring is an important mechanical seal with a wide range of applications. Guide Rings with different materials, structures, and uses have their own characteristics and advantages. Choosing the appropriate Guide Ring can effectively improve the performance and lifespan of the equipment, reduce maintenance costs and failure rates.
