Product Description
This screw rod is made from 99.5% alumina ceramic materials, the use of dry pressing process makes the rod obtain high density and good flexural strength, resulting in better acid corrosion.
On the threaded portion, we use the machining way to make more precise thread size. The thread out of Such processing will get the same accuracy and with metal thread.
We can manufacture products according to your needs, the more common specification is 271mm, below are some of our existing specification.

- Q:I‘m 25, and I‘m getting braces. And also, I‘m getting married June of next year. so I want clear braces for it, but they‘re more expensive and I know that they don‘t work as well as the metal. But I don‘t see many people my age with metal, I see them all with clear sooo I guess I‘m just wondering what your opinion is- anybody around my age who has braces what do you have? and would you recommend the same?
- If the wheels are fine, keep them until they get too small or too many flatspots.
- Q:HiIm Getting My Braces On Soon and id Like To Here From Anyone Currently in Them Or That Had ThemDo Ceramic Braces Break Easily-er Than Metal?Do Tend To Stain Easily?Does Treatment Time Take Longer in Ceramic Even if i Had Just The 6 Front Top Teeth Ceramic and the Rest Metal?And Last Of All Which is Better In-Ovation Or Damon?Thanks In Advance :)
- You have to go to the Volkswagon dealer. For sure. It has happened to me twice with different makes.
- Q:Our kitchen has an original vinyl floor and we are going to get ceramic tile now. I assumed the vinyl would be removed before installing the tile, but a contractor says we should leave the vinyl installed and just cover it. Anybody know if this is likely to be correct. Please, no guesses. The opinions of people who truly know what they are talking about would be appreciated.
- I'm not a contractor but, I have installed ceramic tile before and it would be foolish in my opinion to put down something that expensive and hard to do with vinyl underneath it because, vinyl is soft and will move and allow the ceramic to break when someone walks over it, Not a good ideal, don't hire this contractor at all.You can find all kinds of information at home centers on how to prepare the floor where you are going to lay the tile and one thing that is expressed from Ceramic Tile manufactures is you should not lay it on vinyl or anything else that has a soft like surface.
- Q:I was in Guangzhou, now need to find a place here to make a small works, with other ordinary glass bottle volume almost, if you count the cost of labor and materials, ceramic materials that are expensive or expensive glass material?
- High raw materials, now glass art price is certainly not low, at least with ceramic nanfenbozhong.In short, there are many other factors that determine the price,The key is you want to show what the state, time is sufficient, the price may not be decisive factor. The basic characteristics of glass is exquisite, clear, delicate, exquisite, (also can make coarse effect), ceramic from fine to coarse, differ in thousands.Conclusion: materials should be determined as needed....
- Q:My ceramics teacher taught us how to make slip by using dry clay + water, but atm i don‘t have dry clay . so i was wondering if anyone knows how to make slip another way? or an easy way to dry out clay quickly :) I don‘t know what kind of clay i‘m using (I‘m a newbie) but it seems standard clay
- There isnt know other way. But if you do have clay it can be any consistancy just not fired.like put in the kilm. Just put clay in a bowl, add water and mix really good ha. :)
- Q:What is the working principle of power ceramics?
- The working principle of electric ceramics is as follows:When the voltage is applied to the piezoelectric ceramic, it will produce mechanical deformation with the change of voltage and frequency. On the other hand, when a vibrating piezoelectric ceramic is produced, an electric charge is produced.According to this principle, when given by the two piezoelectric ceramic or a piezoelectric ceramic vibrator (pressure) form and a metal sheet, called bimorph element, applying a signal, it will emit ultrasonic vibration due to bending. Conversely, an ultrasonic signal is generated when an ultrasonic vibration is applied to the bimorph element. Based on the above action, piezoelectric ceramics can be used as ultrasonic sensors.
- Q:What are the advantages and disadvantages of resin crafts and ceramic arts and crafts?
- Ceramic is more fragile than resin, heavier than resin, good plasticity of resin, resin can make all kinds of strange shapes, ceramic more hard and crisp, in this face to face a little bit worse
- Q:I am looking to both plant some plants in the pots and also use smashed ones for hideouts for fish.What have been your experiences using ceramic pots for planting?orWhat have been your experiences using them as hideouts?
- My ciclids would love them as a hideout. I would probally use them if I didn't have so many rocks to make caves. You can't force your fish to use it - but chances are if your fish like to hide, they would like them. Just make sure to bury any rough edges in the gravel so the fish don't get hurt or sand the edges smooth. You can use new ones and bury them halfway (more or less) in the gravel to make smaller caves. A lot of people use clay pots for their plants so they can move the plants as needed - or simply to put a different planting material in the pots and gravel in the rest of the aquarium.
- Q:What is the thickness of ceramic floor tiles?
- 60O and 0.8 - 1.2cm... 800.1 meters in 1.5 - 2.0cm genuine brick
- Q:ceramic hair irons what they used to manage?
- i had this problem in my truck i baught second hand and after checking alot of stuff i finally found that the airbag had already been deployed soooo i just simply took the dash apart and removed the little bulb that was lighting that airbag symbol. ]
