Mingrui offers you a wide range of production facilities like
extrusion, injection moulding, pressing and casting. Depending on
product geometry and quantities, we will choose the suitable
technique for your products.For the final finishing of the parts we
use CNC machining centres, equipped with diamond tools in order to
meet high accuracies.
Our aim is to offer the ideal solution for any application. Our
engineers therefore offer custom solutions that range beyond our
existing product portfolio. With our well-equipped industrial
development facilities, we produce innovations that can be rapidly
commercially exploited.
Main Features:
1) High hardness.
2) High heat resistance: alumina ceramic has excellentthermal
stability,which means that it is widely used in areas where
resistance to high temperatures is essential.
3) Good wear resistance: alumina ceramic is the material of choice
for alumina wear parts.
4) High electrical resistivity: alumina is an electrically
insulating material.
5) High corrosion resistance: it is insoluble in water and only
slightly soluble in strong acid and alkaline solutions. Good
chemical stability of alumina leads to high corrosion resistance.
Company Introduction
Mingrui ceramic manufacture and provides alumina ceramic components
for a wide range of application like Mechanical Equipment,
Electronic & Electrical, Oil Drilling, Medical, Chemical Industry
etc. According to actual application and customer's requirement,
the purities vary from 95%-99.7% and the forming methods will be
different. The forming methods applied in our plant include dry
pressing, isostatic pressing, injection moulding, extrusion
moulding. With experienced engineers and talented workers, we are
confident to offer high quality, high precision, complex components
for customers worldwide.
Mingrui Ceramics has years of experience designing and developing
technical ceramic solutions for a wide variety of applications and
industries.Wear And Corrosion Resistant Ceramic Shaft Chemical
