Ceramic lamp holder&base
Steatite is used to support heating elements in electric heaters, toasters, and ovens.
Steatite is a good high voltage insulator. It holds up under thousands of volts without breaking down.
Steatite ceramic parts are usually small and are formed from dry powder in a compaction press. The parts are then fired in the kiln. Diamond abrasives are used to grind parts to size for high tolerance applications.
Application:
Electric appliance industry / Automotive industry / Mechanical industry
Engineering industry / Electrical heating element industry / LED Lighting Industry
Features
A. 95% alumina or steatite ceramic.heat compression molding, the alumina has been to improved insulation and mechanical strength.
B. The ceramics have no cracks, no burrs, no pinholes, no gaps, and no impurities, surface is smooth, dye absorption is passed.
C. Good insulation and security.
D. Long working life.
E. Precise grinding and polishing, the lighting effect is better.
F. Good quality and competitive price
