Description of zirconia ceramic fixture:
Zirconium oxide (Zirconia) offers low thermal conductivity, superb
wear resistance, excellent fracture toughness, outstanding low
friction coefficient, exceptional resistant strong acid & alkali,
and great high-temperature resistance, strong hardness, electrical
insulation, these make zirconia ceramic as a very important
technical raw material of structural parts used in various
machinery, electrical, electronic, engineering fields.
With high fracture toughness to resistant crack, it's an ideal
machinable advanced ceramics. Our facility is capable of machining
a variety of complicated ceramic parts with a very high accuracy
dimension through fine grinding, lapping, CNC machining, laser
cutting and so on.
These zirconia structural ceramics are widely used to wear ceramic
fixtures, the ceramic plunger in fluid metering, ceramic valve seat
in the pump, ceramic shaft/bearing, ceramic wire guides in the
textile machinery industry.

Manufacturing flow chart of technical ceramic parts
We have in-housing comprehensive manufacturing types of equipment,
including forming, sintering, CNC machining,
precision grinding, laser cutting and so on, it helps us to control
the quality very well, also it greatly benefits cost control.
Packaging proposal and transportation solutions
1. We will keep the ceramic parts inside the inner package to be
fixed without moving, then it will prevent them from collision each
other,
to avoid any cause any chippings during transportation.
2. In addition, the inside of the outer carton will be filled with
sufficient protective kinds of stuff.
