Ceramic insulation<br />

parts<br />

Ceramic parts specially designed for the<br />

plastic industry. Forms a barrier between<br />

the hot and cold parts resulting in reduction<br />

in heat losses. The main benefit from<br />

this is that it will be easier to control and<br />

to get even heat on the heated parts. They<br />

are produced of an material which has<br />

only 7% of the heat conducting capacity<br />

of steel.<br />

The ceramic compression strength is 2100<br />

N/mm 2 , and it is capable of withstanding<br />

temperatures of about 1400°C. Special<br />

design made upon request.<br />

Detaljer av keramik<br />

Materialet har endast c:a 7% av stålets värmeledningsförmåga<br />

varför det med fördel<br />

kan användas för att isolera kalla och varma<br />

detaljer från varandra. Värmeförlusterna<br />

minskar härigenom betydligt och det blir<br />

lättare att styra värmen i den uppvärmda<br />

detaljen.<br />

Materialet har en tryckhållfasthet på 2100N/<br />

mm 2 och en temperaturbeständighet på<br />

1400 °C.<br />

Detaljer med egna mått levereras mot förfrågan.<br />
