The casting takes place in machine or hand-moulded shapes made out of pit-iron sand, the frame out of clay, which lend necessary strength. Cores are inserted for cavities. An advantage to this process is the relatively easy and cost-effective production of the casting model, which in addition can quickly be changed. Because of this, it is particularly well suited for prototype production, complex units and for smaller and medium production runs. <br>  </td> </tr> <tr> <td align="left" width="17" valign="top"><img src="/images/quadrat.gif" width="6" height="6" alt="Kokillenguss" border="0" vspace="6"></td> <td valign="top" class="text10"> <span class="text10g"><strong>Chill Casting</strong></span><br> With chill casting, permanent moulds from heat resistant steel or from cast iron with flake graphite are used. These chill-moulds have a high durability. Cavities and undercuts are produced by metal cores (so-called gates). Core made out of sand ("mixed chill-moulds") and moulds with a bottom part made out of metallic material and a top made out of sand ("half chill-moulds") can be inserted. Chill casting is particularly suitable for medium to larger runs. </td> </tr> </table> </td> </tr></table> </body>
