looked into this once. The problem is that these are made by injecting
plastic into a metal mold under fairly high pressure and temperature ( couple
hundred degrees and PSI )</FONT></SPAN></DIV>

mold has to be strong enough to resist this. It also has to be made so
that it can fit into the molding machine. To get this, you need to spend
several thousand dollars on up depending on the complexity of your
design. </FONT></SPAN><SPAN class=030164318-26032001><FONT

might want to search the web for various plastic companies - see if there might
be an off-the-shelf extrusion or blow molded piece that can be used.
Or change what you are designing to fit something off the
shelf.</FONT></SPAN></DIV>

fabrication<BR><BR></FONT></DIV>

<DIV><FONT color=#000000 size=2>Good afternoon, everyone (please adjust
greeting to your time zone),</FONT></DIV>
<DIV><FONT color=#000000 size=2> How would one go about
commisioning someone to fabricate a number of plastic bowl-shaped cases, or
really any shape someone would want? For example, the case a cell phone sits
in, someone designed that and another guy is making them as we speak. Who are
these people and how do I contact them for a simple, simple half-sphere much
simpler than even the simplest of cell phone cases, and the only thing I would
ask would be flanges to drill screws into. I'm trying to avoid cutting
hundreds of little plastic balls you find at the Chuck E. Cheese Ball Crawl in
half and epoxying the guts into the bottom. Is this type of work tremendously
expensive to have done? </FONT></DIV>
