Have you ever thought about how ceramic cutters are made?These knives are made from the second hard material after diamonds, so it is not surprising that it involves a long manufacturing process.Ceramic kitchen knives and hunting knives are not easy to produce, but it is possible to use the old combinationSchool technology and modern technology.
The manufacturing process starts with raw materials: water, ceramic powder and ceramic grinding balls.The ingredients are mixed in a big drum, like a huge concrete mixer, producing uniform particles of the same size.This device, known as a mill, produces a liquid slurry with a particle diameter of about 1 micron, 1,000 times smaller than a millimeter!
The next stage of manufacture includes a spray dryer that dehydrate the slurry to produce very fine granular powder for filling a specially designed ceramic knife die.Each manufacturer has its own mold to make ceramic hunting knives, ceramic kitchen knives and many other ceramic products.
Once the mold is filled, it will take a lot of pressure at a speed of 1 ton per square centimeter, which will solidify the powder into a very strong knife.This knife is then fired and sintering in a large kiln, like the one you might use in your school ceramics class, but it has to be done at very precise temperatures.
This firing process in the kiln can cause a great contraction, with the blade of the ceramic knife shrinking nearly 75% of its original size and about 50% of its volume.As you can imagine, the shrinkage rate needs to be carefully calculated during the design phase to ensure that the finished product matches the original design specifications.
Once the blade is lit, it uses a diamond wheel to give it a very sharp edge and then connects a handle ready for sale.Ceramic kitchen knives and other blades must be grinded with Diamond wheels because diamonds are the only thing that is harder than ceramics.
If you 've ever seen black ceramic knives, they go through the exact same manufacturing process except for these black onesThe hip blades are made of black zirconium oxide, which makes them stronger and through a type called heat-The equilibrium pressure makes the weaving between molecules closer.
There are many ceramic knife manufacturers today, but due to two very important variables, the hardness of many knives is different: the pressure and heat used in the manufacturing process.Precision is a superior knife, so it is worth buying from the manufacturer who put in time.
As for the sharpness of the blade, it actually depends on the effort and time that is paid during the sharpness process.A high-High quality ceramic knives with careful attention to pressure and heat production can be ground finer without chip risk, while lowDue to the manufacturer's risk of chips and breakage, the high quality knives are not ground very sharp.
Ceramic cutters offer advantages that are not available to conventional steel blades, including superior cutting edges and lighter blades.Thanks to the hardness of the material and these advantages this timeConsuming and expensive manufacturing processes.
