Our advantage

精密不锈钢材料

Material

Our Metal Dome is usually made of 304 stainless steel. This material has a low carbon content (0.08%) and high oxidation resistance. The thickness of the material is 0.06mm, 0.08mm, 0.10mm and 0.12mm respectively; the hardness of the material is between Hv-380 and Hv-420. Japanese imported stainless steel.
  
模具

Mold

We have three sets of molds for each shrapnel size to meet the different pressure requirements of our customers and the different thickness and hardness of our materials. The standard pressure range of our products is 100g to 600g. We can also produce other types of shrapnel with pressures outside the standard range according to individual customer requirements.
寿命

Life cycle test

Our Metal Dome life test results are stable, with a maximum of 1,000,000 cycles of shrapnel life. When testing the life of the shrapnel, it should be noted that the material and condition of the shrapnel plane, the design of the test head, and the pressure applied when pressing the shrapnel may affect the test results.
