Dongguan Yuhuana Togafitiga Tekonolosi Co., Ltd. Na faia i le 1998, o se gaosiga, suʻesuʻe ma atiaʻe, faʻatau ma le tautua i se tasi o pisinisi ma faʻatonuga i le tasi o pisinisi ma fefaatauaiga. It is mainly committed to the research and development and customization of non-standard hardware fasteners, as well as the production of various precision fasteners such as GB, ANSI, DIN, JIS, ISO, etc.

The laboratory is equipped with a complete range of testing equipment: 1. Vickers hardness tester and Rockwell hardness tester to ensure the hardness requirements of the product. 2. The torque meter is used to detect and record the torque value of each product to ensure that the product meets the torque value required by customers. 3. O le masini tenisi e faʻaaoga e faʻataʻitaʻi ai le malosi o le tele o se mea poʻo oloa. 4. O le pusaaisa ua faʻaaogaina mo le Hydrogeen o loʻo iai le suʻega o le suʻega e faʻataʻitaʻi pe o le oloa o le dehydrogenin ma puipuia le oloa mai le gagau. 5.x-Ray Free Freecrecence, o le tulaga-auiliiliga o oloa, ae faʻapea foʻi le siosiomaga puipuiga. 6. We also have salt spray testing machine, metallographic inlay machine, metallographic cutting machine, constant temperature and humidity box, friction resistance testing machine, leakage prevention tester, two-dimensional, head percussion table, digital display micrometer, ring gauge, competition gauge, needle depth meter and other testing equipment, each product has undergone strict testing and testing to ensure that the product quality meets and sili atu i le tagata faʻatau faʻamoemoega.

The company has multi-station cold heading machine, two-mode four, three-mode three, three-mode six, four-point cold heading machine, tooth rolling machine, combined tooth rolling machine can make M1-M16 screws. At the same time, there are gasket stamping machines and other equipment, which can produce a variety of different gaskets, elastic pads, flat pads, square pads, etc. The nut cold heading machine can be used as a nut for M2-M16, and the automatic lathe can be used as a knurled nut and an inlay nut. Maualuga-o le le mautonu stamping masini, alualu i luma feoti e mafai ona maua sili atu nai lo 0.1mm, tasi oti e mafai ona maua ai le 3-5m mafiafia sikuea sikuea vaega. The machining center produces precision customized lathe parts, the tolerance requirements can be as small as 0.006mm, the centering machine produces cylindrical lathe parts, and the CNC lathe can produce various precision custom lathe parts. E mafai lava ona matou tuʻuina atu ia te oe i ituaiga o faʻo, kesi, o nati, pulumu vaega, faʻailoga faʻavasega vaega ma isi oloa. O matou o tagata poto masani i le le masani-pito i luga o fofo, maua ai le tasi-taofia-taofia meafaigaluega meafaigaluega a le fonotaga.
