This process conveniently fits between Vacuum Casting and Thermoplastic Injection Moulding in the prototyping / manufacturing chain. </DIV> <DIV>&nbsp;</DIV> <DIV>This is a cold injection process that does not require pre-heating of moulds or post curing of castings. Larger sized components can be produced and several moulds can be cast consecutively, leading to quicker production times. Tools are made from Silicone, Resin, Model Board or Aluminium, and can yield anything from 50 up to 1000+. This process is mainly used for larger and simpler parts with a typical wall thickness of 2-3mm+. </DIV> <DIV>&nbsp;</DIV> <DIV>As with vacuum casting, a wide range of production simulant materials are available, offering a wide range of properties; rigid or flexible; solid or foamed, with a density as low as 40 kg/m³. Rigid self-skinning materials, where the surfaces are hard and solid enclosing a foam core, can be moulded to produce lightweight but rigid components.</DIV> <DIV>&nbsp;</DIV> <DIV>Rigid and flexible RIM components are extensively used in: Exterior and interior automotive applications Large Machinery Domestic appliances Housings for electrical goods Medical Office furniture Sporting goods Advantages of Rim Casting: Quick manufacture of tooling using RP technology masters or patterns Relatively low tooling costs Tough, durable, flexible and rigid components High quality and large component size High impact strength and dimensional stability Flexibility, low cost high or low volume production Inserts and metal reinforcement can be over moulded into components Good thermal, electrical and sound insulation properties Can be flame retardant to meet UL 94 V0 environmental compliance</DIV> <DIV>&nbsp;</DIV> <TABLE cellPadding=0 width="100%" align=left border=0> <TBODY> <TR> <TD> <DIV align=center><B>news title</B></DIV></TD> <TD width="32%"> <DIV align=center><B>creatime </B></DIV></TD></TR> <TR> <TD> <DIV align=center><A href="http://www.higrademould.com/admin/news/newsen113.htm" target=_blank>How Higrade Mould Controls Its Mould Quality</A></DIV></TD> <TD width="32%"> <DIV align=center>2009-12-29</DIV></TD></TR> <TR> <TD> <DIV align=center><A href="http://www.higrademould.com/admin/news/newsen111.htm" target=_blank>Got to Get Out More</A></DIV></TD> <TD width="32%"> <DIV align=center>2009-12-22</DIV></TD></TR> <TR> <TD> <DIV align=center><A href="http://www.higrademould.com/admin/news/newsen107.htm" target=_blank>How to Improve Hot Runner Installation and Service Ability</A></DIV></TD> <TD width="32%"> <DIV align=center>2009-12-15</DIV></TD></TR> <TR> <TD> <DIV align=center><A href="http://www.higrademould.com/admin/news/newsen106.htm" target=_blank>Higrade Mould moves into new home!</A></DIV></TD> <TD width="32%"> <DIV align=center>2009-12-8</DIV></TD></TR> <TR> <TD> <DIV align=center><A href="http://www.higrademould.com/admin/news/newsen105.htm" target=_blank>An On-Line Hot Runner Justification Tool</A></DIV></TD> <TD width="32%"> <DIV align=center>2009-11-24</DIV></TD></TR> <TR> <TD> <DIV align=center><A href="http://www.higrademould.com/admin/news/newsen104.htm" target=_blank>Facing the Quality Challenges of Large, High-Precision Tooling</A></DIV></TD> <TD width="32%"> <DIV align=center>2009-11-17</DIV></TD></TR> <TR> <TD> <DIV align=center><A href="http://www.higrademould.com/admin/news/newsen103.htm" target=_blank>Something about tolerance and limits </A></DIV></TD> <TD width="32%"> <DIV align=center>2009-11-10</DIV></TD></TR></TBODY></TABLE> <DIV align=left>&nbsp;</DIV> <DIV align=left>&nbsp;</DIV> <DIV align=left>&nbsp;</DIV> <DIV>&nbsp;</DIV></td> </tr> </table> </div></td> </tr> <tr> <td><div align="center"> <table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td width="75%" height="35" align="left"><div align="center">Author:</div></td> <td align="center"><div align="center">Time:2010-1-5</div></td> </tr> </table> </div></td> </tr> </table> </td> </tr> </table></td> </tr> </table></td> </tr> <tr> <td height="63" bgcolor="#EAEAEA"> <table width="98%" border="0" cellspacing="1" cellpadding="1"> <tr> <td colspan="3" height=3></td> </tr> <tr> <td width="5%"><div align="center"><img src="../../images/bottom_block.jpg" width="8" height="35"></div></td> <td width="86%" class="STYLE3_2">Copyright&nbsp;&copy;&nbsp;:Higrade(Qingdao) Moulds &amp; Products Co., Ltd.&nbsp;&nbsp;&nbsp;&nbsp;Add: No.1009,Chongqing Road,Qingdao City,Shandong Prov.,China<BR> Tel:+86-532-84819378&nbsp;&nbsp;&nbsp;&nbsp;Fax:+86-532-84819379&nbsp;&nbsp;&nbsp;&nbsp;Website:<A href="http://www.higrademould.com">http://www.higrademould.com</A>&nbsp;&nbsp;&nbsp;&nbsp;E-mail:<A href="mailto:higrademould@vip.163.com">higrademould@vip.163.com</A></td> <td width="9%"><a href="#" target="_blank"><img src="../../beiannew/logo.gif" width="31" height="32" border="0"></a><a href="http://218.57.19.118/" target="_blank"><img src="../../beiannew/01.gif" width="28" height="35" border="0"></a></td> </tr> </table> </td> </tr> <tr> <td height="10" bgcolor="#FFFFFF"></td> </tr> </table> <table width="1003" border="0" cellspacing="0" cellpadding="0"> <tr> <td><div align="center"></div></td> </tr> </table> <!-- End ImageReady Slices --> </body> </html>
