Isostatic pressing is our specialty and is used where the size, shape or batch size of components makes dry pressing impracticable or uneconomical. We have a wide range of isostatic mandrels available, offering customers economic manufacture of standard tubular forms, plates, etc. Grinding, lapping, polishing & honing are carried out using diamond abrasives. These techniques are used to obtain tight control of dimensions and surface finishes.
Application:
Alumina ceramic is mainly used in large power equipment, IC MOS tube, IGBT chip heat conducting insulation, high frequency power supply, communication, mechanical equipment, strong current, high voltage, high temperature and other thermal heat insulation parts need products.
Physical properties: high thermal conductivity, high voltage insulation resistance, high temperature resistant, abrasion resistant, high strength.
