Happy Mid-Autumn Festival

Innovaera will closed from Sept.13-Sept.15 for Mid-Autumn Festival.

Mid-Autumn Festival is a traditional festival in China. It used to be as important as Spring Festival is usually celebrated in the Lunar August 15. This festival is to celebrate the harvest and to enjoy the beautiful moonlight.

To some extent, it is like Thanks Giving day in the USA. On this day, people usually get together with their families and have a nice meal. After that, people always eat delicious moon cakes and watch the moon.

The moon is always very round on that day， and makes people think of their relatives and friends. It is a day of pleasure and happiness.

Hope you have a wonderful Mid Autumn festival!

Zirconia ceramics for the production of mobile phone backplanes

With the advent of the 5G era, zirconia ceramics have become the new favorite material for mobile phone backplanes.

By the end of 2018, 154 mobile operators around the world are conducting 5G technology testing or testing, and the number of countries participating in 5G has expanded to 66. With the advent of the 5G era, the mobile phone industry will usher in a new round of changes, and the mobile phone backplane market is facing a reshuffle. Among them, zirconia ceramics stand out in a new round of technical reshuffles.

Advantages of zirconia ceramics as raw materials for mobile phone back sheets.

The 5G era requires faster signal transmission, which is 1~100 times that of 4G. 5G communication will use the spectrum above 3Ghz, and the wavelength of the millimeter-wave is shorter. Compared with the metal backplane, the ceramic backplane has no interference to the signal and has unparalleled superior performance of other materials, which is favored by mobile phone manufacturers.

Comparison and difference between several major mobile phone backplane materials.

	plastic	metal	glass	ceramic
Exterior	bad	normal	normal	Great good
Feel	bad
Coloring difficulty	Simple, can do a variety of surface patterns	Normal, prone to paint peeling	Difficult, general film, coating adds texture	Simple, can do a variety of surface patterns
Weight	Thicker and lighter	The thinnest and lightest	Thicker, heavier	Thickness control is generally
Rigidity	Bad, Plastic deformation is obvious	Normal, have a certain plastic deformation	Good, Poor plastic deformability	Good, Small plastic deformation
Brittleness	normal	good	Bad, But still able to meet the drop test	Significant plasticity enhancement after material modification, meeting the drop test
Hardness/wear resistance	bad	normal	normal	Great good
Heat dissipation	bad	good	Very bad	no effect
Cost	lowest	normal	Higher
Electric porcelain shielding	no effect, Integrated molding	Great impact, need to be cut off with plastic	No effect can be integrated

Among all ceramic materials, zirconia ceramics have the advantages of high strength, high hardness, acid and alkali corrosion resistance and high chemical stability, as well as scratch resistance, no signal shielding, excellent heat dissipation performance, good appearance, etc. Features, therefore become a new type of mobile phone body material after plastic, metal, glass. At present, the application of zirconia ceramics in mobile phones is mainly two parts of the backboard and the fingerprint identification cover.

The advantage of ceramic deburring cutters

Zirconia Ceramic material is ideal for removing the burrs of plastic, metals and rubber. Because it is durable and has high hardness.

Our knife can smooth the edge and remove sprayed points and separation lines from mould halves. Furthermore, it is cabinet and easy to use avoid injury. Different kinds of blades can be replaced so that the cost is effective.

Canpared to traditional steel blades, ceramic blades have many benefits:
1. never rusts, no special oil coating or maintenance
2. light weight
3. stay edge and sharp
4. Very sharp
5. Corrosion resistant
6. non-conductive

Ceramic Metallization Process

INNOVACERA is a leading supplier that makes metalized ceramics. It is used in brazed solutions.

Metallization applies a thin metallic coating to an area of ceramic parts. Innovacera’s metalized ceramics have a superior brazing characteristic. The thin metallic coating includes molybdenum manganese (Mo/Mn) and tungsten (W). After metallic coating, they will be plated with nickel, gold, silver, and so on.

The plating method is electroplating. Depending on the ceramic size and the position of metalized, it will decide to barrel or hang plating.

The Mo/Mn thickness is 10-50um, nickel plating is 2-10um. It is flexible. We can do it according to your request.

As experts in different applications, Innovacera is available to do metalizing on the plate, rod, tube, and complex ceramic bodies.

The material for metallization is available for:
Aluminum Oxide

The benefits of the material:
Low-temperature firing
Fast speed process
Uniform coating, thickness, and density

Applications for metallization products:
Vacuum Interrupter Ceramic Tube
Feedthroughs
Isolator Flanges
Gas Discharge
Electron Tube
X-Ray Tube
Medical Devices
Vacuum Electronic Devices

How to make boron nitride ceramic part?

When we make boron nitride ceramic part, generally we make big billet, our billet max size is 420 * 430 * 220 mm, and then machine it as other small part or customized shape part. In the producing process, we separated powder with graphite mould by graphite paper to make sure there is no reaction between them.

Boron Nitride is easy to machine it, so we can machine it by common tool and we machine it without water or other liquid. We also have precision CNC engraving and milling machine to make high precision part. Generally the best tolerance we make is +/-0.03 mm (small part) or +/-0.05 mm for bigger part.

Our BN part Produce process is as belows: Powder granulation – Put Powder in the graphite mould–Prepare Dry – Hot Press with sintering-Machine.

In the sintering process, the product is Sintering together with hot pressing. Our sintering furnace is pressing is from both the top an bottom that can make the product is more dense and uniform to make sure the quality, some other factory sintering furnace is just pressing from one side only. Our factory total have 9 sets sintering furnace and it was designed by our own engineer who are from the famous university. Our 99% BN ceramic part sintering temperature is 2000℃ and the compound boron nitride sintering temperature is 1850℃。

Innovacera boron nitride part such as ceramic insulator part for furnaces, ceramic crucibles and boats for molten melting, nozzles for powder metal gas atomization and amorphous strips are hot sales products.
