Factory Information

Our High Pressure Sodium (HPS) and Ceramic Metal Halide (CMH) lamps produced by Budapest factory, which operates since 1896.
Our ceramic plant close to Budapest factory where we manufacture ceramic products. The plant operates since 2006.
We have many decades experience in powder metallurgy and other ceramic technologies.

About Ceramics Technology

The company has world-class sintering capability in H2 gas (and other gases) at high temperatures. This sintering technology is rare among manufacturers in the EU (in translucent ceramic production). Our doping capabilities and experience maximizes the potential of our products according to the customer’s request. We use high purity 99.99% aluminum oxide to produce our ceramic parts.

Manufacturing process steps

Molding

Feedstock is a preparation process which means mixing the ceramic powder with binding agent.

Injection molding is the method of compaction of ceramic powder fed and injected into a mold cavity by means of a screw rotating in cylinder.

Presintering  means the final white color (green part) compact can be machined to its final shape before sintered. (eg. cutting process). Also called dried part.

SSF sintering is where the dried parts pass through a controlled heating process, and the oxides are chemically changed to cause bonding and densification. The fired part will be smaller by 20-25% than the dried part.

 

Extrusion

Feedstock is a preparation process which means mixing the ceramic powder with binding agent.

Extruder means ceramic can be formed into shapes via extrusion, extrusion is used to produce pipes.

Pre-sintering means the final white color (green part) compact can be machined to its final shape before sintered. (eg. cutting process). Also called dried part.

Sintering is where the dried parts pass through a controlled heating process, and the oxides are chemically changed to cause bonding and densification. The fired part will be smaller by 20-25% than the dried part.

 

Pressing

Spray-drying is a method of producing a dry powder

Press machine means die pressing is the powder compaction method involving uniaxial pressure applied to the powder placed in a die between two rigid punches.
