What’s the metal domes material?

Monday, August 19th, 2013

The metal domes (snap domes) material is general use stainless steel. Stainless steel in various countries, in general, the Japanese SUS301 is used often, but sometimes also use SUS304 material. The difference between these two materials is the chemical composition,304 carbon ratio is higher, but the hardness is note better than 301, so it is generally to use SUS301 to make metal domes (snap dome). Of course, there are some other materials, such as phosphor bronze C5210, One side with silver SUS from Korea.

The proper selection of materials is very improtant for product quality of metal domes(snap domes),if improper selection hardness of the material, it will generally result in “Death KEY” phenomenon (pressing down, then metal dome disappear automatically pops up function).We can’t find out this issue in short-time used and with eyes,we need life test machine and force test machine to test the result.

Our company has a professional production experience, so the choice of materials and incoming detection testing standards will be strictly in accordance with the strict inspection of incoming inspection, so our metal domes(snap domes) have maintained excellent quality.

How to improve metal dome click feeling?

Monday, August 12th, 2013

The customers have one main concerned about the metal dome click feeling , so what’s the relationship with it? How can we improve it?

Metal dome click feeling is not only with relationship with metal dome shape, force, re-force, stroke, etc., but also with the silicone keypad assembly.

1. Adjust the metal dome force and re-force, then increasing metal dome click feeling;
2. Choice higher metal dome stoke;
3. well-designed silicone buttons with metal dome;
4. Assemble metal domes in middle of silicone keypad, the more partial metal dome assembly, the more feel worse.

PCB board mounting metal domes

Wednesday, July 10th, 2013

We supply PCB board mounting metal domes. We have many years of metal domes(snap dome, tactile dome) production experience, and they are widely used in many electronic products,such as membrane switch , the phone keypad, micro-switches, communications equipment, touch switches and other products.

Metal domes have four-leg metal dome(cross shape), triangle metal dome, round metal dome, rectangular metal dome, square shape metal dome and other special shape to choose from. Some models available with legs, legs length ranging from 1mm to 3mm to facilitate mounting on the printed circuit board. Each shape has different sizes and force for customers to choose, the size from 2mm to 20mm, the force from 100 to 800g range.

We also have gold-plated and nickel-plated metal domes to choose from, all made of imported high-quality pre-gold and pre-nickel plating materials: coating uniformity, strong adhesion, good corrosion resistance, suitable for products with higher requires with contact resistance.

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! ! !
