The technique has evolved from the production of combs and buttons to major consumer, industrial, medical, and aerospace products.</P> <P>In 1868, perhaps in response to a request by billiard ball maker Phelan and Collander, John Wesley Hyatt invented a way to make billiard balls by injecting celluloid into a mould. By 1872, John and his brother Isaiah Hyatt patented the injection moulding machine. The machine was primitive yet it was quite suitable for their purposes. It contained a basic plunger to inject the plastic into a mould through a heated cylinder.</P> <P>Revolutionizing the plastics industry in 1946, James Hendry built the first screw injection moulding machine with an auger design to replace Hyatt's plunger. The auger is placed inside the cylinder and mixes the injection material before pushing forward and injecting the material into the mould. Today, almost all injection moulding machines use this same technique.</P> <P> <TABLE class="" width="100%" border=0> <TBODY> <TR bgColor=#d9d2c3> <TD bgColor=#f0f0f0 height=30> <DIV align=center><STRONG>news title</STRONG></DIV></TD> <TD bgColor=#f0f0f0 height=30> <DIV align=center><STRONG>creatime </STRONG></DIV></TD></TR> <TR> <TD bgColor=#f9f9f9 height=30> <DIV align=center><A onmouseover="javascript:this.style.cssText='CURSOR: hand;'" style="CURSOR: hand" href="http://www.higrademould.com/admin/news/newsen125.htm" target=_blank>Choosing the Correct Molding System</A></DIV></TD> <TD width="33%" bgColor=#f9f9f9 height=30> <DIV align=center>2010-2-22</DIV></TD></TR> <TR> <TD bgColor=#f9f9f9 height=30> <DIV align=center><A onmouseover="javascript:this.style.cssText='CURSOR: hand;'" style="CURSOR: hand" href="http://www.higrademould.com/admin/news/newsen123.htm" target=_blank>the direction of China s mold industry and prospect analysis</A></DIV></TD> <TD width="33%" bgColor=#f9f9f9 height=30> <DIV align=center>2010-2-9</DIV></TD></TR> <TR> <TD bgColor=#f9f9f9 height=30> <DIV align=center><A onmouseover="javascript:this.style.cssText='CURSOR: hand;'" href="http://www.higrademould.com/admin/news/newsen122.htm" target=_blank>the future prospects of the die&amp;mold</A></DIV></TD> <TD width="33%" bgColor=#f9f9f9 height=30> <DIV align=center>2010-2-2</DIV></TD></TR> <TR> <TD bgColor=#f9f9f9 height=30> <DIV align=center><A onmouseover="javascript:this.style.cssText='CURSOR: hand;'" style="CURSOR: hand" href="http://www.higrademould.com/admin/news/newsen120.htm" target=_blank>How to Use Hot Runner Solutions to Help Your Customer</A></DIV></TD> <TD width="33%" bgColor=#f9f9f9 height=30> <DIV align=center>2010-1-25</DIV></TD></TR> <TR> <TD bgColor=#f9f9f9 height=30> <DIV align=center><A onmouseover="javascript:this.style.cssText='CURSOR: hand;'" href="http://www.higrademould.com/admin/news/newsen119.htm" target=_blank>Hot Runner Selection</A></DIV></TD> <TD width="33%" bgColor=#f9f9f9 height=30> <DIV align=center>2010-1-17</DIV></TD></TR> <TR> <TD bgColor=#f9f9f9 height=30> <DIV align=center><A onmouseover="javascript:this.style.cssText='CURSOR: hand;'" href="http://www.higrademould.com/admin/news/newsen115.htm" target=_blank>Mould business  Quality is first important</A></DIV></TD> <TD width="33%" bgColor=#f9f9f9 height=30> <DIV align=center>2010-1-12</DIV></TD></TR> <TR> <TD bgColor=#f9f9f9 height=30> <DIV align=center><A onmouseover="javascript:this.style.cssText='CURSOR: hand;'" href="http://www.higrademould.com/admin/news/newsen114.htm" target=_blank>What is RIM</A></DIV></TD> <TD width="33%" bgColor=#f9f9f9 height=30> <DIV align=center>2010-1-5</DIV></TD></TR> <TR> <TD bgColor=#f9f9f9 height=30> <DIV align=center><A onmouseover="javascript:this.style.cssText='CURSOR: hand;'" href="http://www.higrademould.com/admin/news/newsen113.htm" target=_blank>How Higrade Mould Controls Its Mould Quality</A></DIV></TD> <TD width="33%" bgColor=#f9f9f9 height=30> <DIV align=center>2009-12-29</DIV></TD></TR> <TR> <TD bgColor=#f9f9f9 height=30> <DIV align=center><A onmouseover="javascript:this.style.cssText='CURSOR: hand;'" href="http://www.higrademould.com/admin/news/newsen111.htm" target=_blank>Got to Get Out More</A></DIV></TD> <TD width="33%" bgColor=#f9f9f9 height=30> <DIV align=center>2009-12-22</DIV></TD></TR> <TR> <TD bgColor=#f9f9f9 height=30> <DIV align=center><A onmouseover="javascript:this.style.cssText='CURSOR: hand;'" 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="33%" bgColor=#f9f9f9 height=30> <DIV align=center>2009-12-15</DIV></TD></TR></TBODY></TABLE></P></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:higrade</div></td> <td align="center"><div align="center">Time:2010-3-1</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;
