Life cycle of metal dome is a key point all people concerned, but do you know why each manufacturer has a different result about life cycle? Some even has very big difference?
Do you know which factors will affect the life of metal dome? You will get the answer after read below words.
The first factor: Raw material. As we know, different material of metal dome, with different carbon content, hardness, etc. Thus the metal dome produced will naturally be different. There are mainly two materials of metal dome used in market, SUS301 and SUS304, we mainly use material SUS301. Welcome to visit our blog “what’s the differences between SUS301 and SUS304” and “Comparison of material properties and hardness between SUS301 and SUS304” for more details.
The Second factor: Life test method. Maybe you’ve been in this situation, you ask same metal dome from different supplier, but with different life cycles and you are confused about it. The reason is that when we use different life test method, such the diameter of test probe, material of test probe, test speed, test force to test the metal dome, the result will be different.
For example, under the same test speed and force, tungsten steel test probe has a different test result compared with silicon test probe. It’s easy to guess who has the tougher test conditions.
So the same principle, 1.5 times test force has different test result compared with 1.1 times test force.

The Third factor: The click ratio.When click ratio is too high, the rebound force will more lower, thus the metal dome is easy been sunk after long time pressing, so it is easy to reduce the life of metal dome.
The Fourth factor: Accuracy of assembly. The life is the best when we always press the center of metal dome, but the large deviation of assembly, it will cause us to miss the center of metal dome and reduce the life of metal dome, and also will have other issues.
And the life time are also related with the shape, height of metal dome, tooling produced, and operation habits. Usually round type will have better life than four legs and triangle, higher height with shorter life of metal dome; The more precise the mold, the better the life; If the operator press the dome with excessive force for long time, its will reduce the life of metal dome as well.
