Based on their different usage, Chain Lock and V lock are designed variously to maintain the optimized mechanical properties and work life, thus make it fit with the chain in G100(Grade D)。 倚天屠龙记纪晓芙 纪晓芙扮演者是谁 纪晓芙谁演的 雪梨影院

All designs of chain connector are made by CAD; the infinity element are abstracted to have stress analysis and optimal study 。
All the raw materials are specially purchased from England with careful choice, in which alloy properties and dimension are strictly controlled, so it is no doubt the chain connector can be used in rough condition. Each lot of raw material are through metallographic examination and labeled against their composition and physical appearance.
All the fined forgings are made in Premier Stampings, England, they are treated by means of intermediate frequency heating, The heating temperatures are controlled with infrared rays, this will help prevent rough grains and oxidized decarburization
All the parts are through CNC machining, each half link are machined and formed only with one fixture and one time setting, therefore, the accurate dimension are realized by this way.
5、 Heat treatment
Epson air controlled furnaces are employed to process the heat treatment to lead the consistent treatment result and avoid oxidized decarburization.
Each pair of chain connectors are tested with the load 2.5 times over its capacity-and have flaw detection to maintain its safety during their serving period.
7、 Quality Archive
Each chain connector has their unique label which can be traced back to its any former manufacturing chapter.
