metal dome trends of development

Thursday, June 27th, 2013

Since the outbreak of the 2008 world economic crisis, the development of all lines are subject to an unprecedented impact, our metal dome industry is no exception.

Of course, the advent of the economic crisis is also a new opportunity soon. Backward, outdated, inefficient, and so of production lines will be phased out, while turning with the development of innovative, proprietary products. Metal dome industry is the same. Previously the marketing of small metal dome manufacturing plants are based in Shenzhen Huaqiang North of China (most are counterfeit cellphone)  ,but as technology development, and now toward the touch, smart phone development, the marketing was shrinking quickly, many small metal domes factories have been closed during this period.

After the economic crisis, a new pattern emerged. Now metal dome main used in high-end products, such as remote control, headphones, panel switches. Cellphone is mainly for export, intelligent phone are basic to the domestic marketing. Although the current technology is developing, the key switches  turn to touch screen developing, but in many industries still have to use the key switches. Because many of our customers also need the click feeling, metal domes have a good click feeling, no others can instead of.

The emergence of a crisis is also an opportunity to come, we must change our concepts, real-time to adjust our thinking to marketing, so that our company can have sustainable businesses to grow and develop. We also firmly believe that, regardless of how today’s technology development, how the touch screen brings a lot of fun, but the metal dome is also not disappear, because each product has its own advantages, their living space. So this is just want you to find it! ! !

Fingerprint attendance machine is the fingerprint recognition attendance machine,the contact membrane keypad use our metal domes, then what type of the metal dome will used?In generally to use triangle metal dome, with higher force, such as 300-500 grams,the 5-8mm diameter.

Then make the metal dome with adhesive sheet(we call metal dome sheet or dome array), a piece of sheet with the total keys to paste, very convenient and simple. Then the material of transparent is very convenient to assemble.

We have customers are specialized in making fingerprint attendance machine, so the technology is more mature. If you have needs in this area, please feel free to contact us.

The triangle metal domes can be made with adhesive sheet?

Wednesday, April 17th, 2013

The triangle metal domes can be made with adhesive sheet? The answer is that some can do, others can not be done.

Because the triangle metal domes can be divided into triangle metal domes with legs and without the legs two types, metal domes without legs can be made with adhesive sheet (we also call metal dome array). But the metal dome with legs can not be done, this is only we can make the legs inserted into the prined circuit board vias, and then bend on other side, it can be fixed.

The triangle metal domes with adhesive sheet can also be divided into one-key dome array and dome array with many keys, they are suitable for different switches.

If you need to know more details of the triangle metal domes, please feel free to contact us.
