Ceramic rod needleSpecial ceramic materials mainly developed from high-strength zirconia raw materials: they are drop-resistant, wear-resistant, super strong, super hard, high temperature resistant (fire-resistant), super corrosion-resistant, never rust, and Oxidation, insulation, self-lubricating and other excellent properties!

Introduction to zirconia ceramic rods

Zirconium oxide ceramic needlesThe earliest production used was a type called Wirecenterless that originated from the watch manufacturing industry. Craftsmanship, this is a technology for processing clock shafts. At the beginning, workers manually use wires to make pins. In order to ensure coaxiality and the diameter of the inner hole, wires are inserted into the center of the shaft for processing. Adamant, Kycera and Toto all use This process. The molding methods currently used include dry pressing molding, extrusion molding and injection molding. Dry pressingThe molding equipment process is simple, but the dimensional accuracy of the molded body is low, and the sintered body is difficult to achieve uniform density. ; Extrusion molding is to fully mix ultra-fine PSZ powder with binders and lubricants to make the powder have a certain fluidity, and extrude it through an extrusion nozzle under a certain pressure. Its production efficiency is high. , but the obtained body does not have an optical fiber introduction groove and needs to be machined, which not only increases the production cost, but also easily damages the ceramic body; the injection molding process is currently the most widely used!
Zirconia ceramic rod needle forming process
Ceramic rod pins are first formed by grade pressing or injection molding, and then sintered at high temperature to form a ceramic rod blank, which is then polished, chamfered, finely ground, etc.; the diameter of the ceramic rod pins can be up to 80mm. minimumTo achieve 0.5mm, the length can be more than 450mm, the dimensional accuracy can be accurate to 0.001mm, and the concentricity can be 0.005mm.

Zirconium oxide ceramic rod product features:

Zirconia ceramic needles have excellent properties such as resistance to falling, wear resistance, super strength, super hardness, high temperature resistance (fire resistance), super corrosion resistance, never rust, anti-oxidation, insulation, and self-lubrication! Regardless of the sun or rain ( Even acid rain) or moisture have no effect on the surface and rods. The resistance to ultraviolet radiation and color stability fully reach international gray scale level 4-5. Changes in high temperatures will not affect the properties and appearance of the material. The reasonable combination of flexural strength and elasticity gives ceramic rods high impact resistance. The dense material surface makes it difficult for dust to adhere, making it easier to clean. Ceramic rods also have very good fire resistance properties, they won't melt, drip or explode and remain stable for long periods of time. Ceramic rods are easy to maintain and require no paint or protective coating on the surface or cutting edges.

A. Drop-resistant--our products have this technology and remain intact after being dropped from a high altitude. They are very resistant to drops
B Impact resistance--its structure makes the panel extremely resistant to impact, which has been confirmed by daily actual use
C. Resistant to scratches - making the ceramic rod scratch-resistant and keeping its shape undamaged for a long time
D Wear resistance - Ceramic rods have strong wear resistance and are suitable for places where heavy objects are placed or where frequent cleaning is required
E Easy to clean - tight non-penetrating surface makes it difficult for dust to adhere to it
F Moisture resistance--the water absorption of ceramic plates is comparable to that of glass
G Anti-UV - Ceramic rods are not affected by weather changes, regardless of sun or rain
H Fire resistance--the surface of the ceramic rod has strong protection against burning cigarettes
I Anti-static - Ceramic rods are proven to be anti-static and are ideal for use in dust-free areas
J Chemical corrosion resistance - Ceramic plates have strong chemical corrosion resistance, acid resistance, and toluene oxidation resistance.
