What is a ceramic ring?
The shell of the ceramic ring is machined from zirconia, a material with high mechanical strength and high fracture toughness at room temperature. The coefficient of thermal expansion of zirconia is similar to that of metal, so it is the perfect combination with metal materials. Zirconia grains are relatively refined and can complete high coarseness processing; zirconia has excellent biocompatibility and is also widely used in the biomedical industry, such as ceramic teeth.
Ceramic rings can be customized in various colors, such as black and white, yellow, blue, and green, and can be made into diamond cut and diamond rings according to demand, so ceramic has become one of the common materials in the jewelry ring industry.
What is a semi-ceramic resin ring?
The semi-ceramic resin ring is based on a ceramic zirconia shell, which is concave in the middle. Craftspeople mix epoxy resin liquid, then pour the liquid into the groove, and wait for the resin to cure to get a beautiful semi-ceramic resin ring.
Ceramic rings or semi-ceramic resin rings may be displayed in personal or industrial production, such as DIY and CNC machining.
What are the advantages of ceramic rings?
The ceramic ring is resistant to aging, constant yellowing, and high temperatures. It is also highly hard and not easy to break. Ceramic rings are not only used in the jewelry industry but also as raw materials for smart rings, such as RFID rings and smart health rings.
The ceramic ring and metal ring are compared; the ceramic ring weight is very light, and the skin is perfect, so it will not sting hands.
Compared with wooden rings, ceramic rings have high production efficiency. However, the process is more than wooden rings; it can achieve automated production, and most wooden rings can only be handmade or semi-automated production, which means that the accuracy of ceramic rings is much better than that of wooden rings, wooden rings are not water resistant, easy to leave water stains.
The appearance of a ceramic ring is more innovative than that of other rings as long as there are drawings that can be processed to achieve the desired look.
What are the disadvantages of ceramic rings?
The main disadvantages of ceramic rings are high hardness and complex processing, so the output is low. The price of ceramic rings is much higher than that of metal rings (except precious metals), and the scrap rate is high because it requires higher accuracy than metal and wood. But for the semi-ceramic resin ring, because of the lack of a shell, we use epoxy resin material as a substitute; epoxy resin material has the advantages of mass and appearance customization diversification, so the mass jewelry ring market also loves the semi-ceramic resin ring.
