Adept Custom Molders' (ACM) can produce injection molded plastic parts from cold runner molds, hot runner molds and insulated runner molds. <P>A few considerations when selecting the system to use include:</P> <UL> <LI><B>Part complexity</B> <LI>Color requirements <LI><B>Physical characteristics</B> of material <LI><B>Type of plastic material to use</B> - virgin or "regrind" <LI>Color changes during production run <LI><B>Single or multiple design</B> production <LI>Volume of parts to be produced <LI><B>Production speed </B>required </LI></UL> <P>Each molding system offers advantages and disadvantages. We can help you select the correct molding system to <B>manufacture your plastic parts as economically as possible</B>. </P> <H3>Cold Runner Molding: The Pros and Cons</H3> <P><A class=norm href="http://www.acmolders.com/cold-runner-mold-acm.htm">Cold runner&nbsp;injection molding is best for manufacturing plastic parts of simple design</A> or when more than one color of the part needs to be produced. Molds are generally less expensive to build and maintain than hot runner or insulated runner molds. <P>With a cold runner mold, the runner (excess material retained in the feed channels) is cooled and ejected with the part. <B>Every cycle, a part and a runner are produced</B>. Waste material must be either disposed of or reground and reprocessed. <H3>Hot Runner Molding vs. Cold Runner Molding</H3> <P><A class=norm href="http://www.acmolders.com/hot-runner-mold-acm.htm">Hot-runner plastic injection molding systems are used when large runs have to be manufactured in highly automated production</A>. Additionally, technological advances enable us to build molds with gates positioned to yield the best quality molded parts.&nbsp; <P>The primary difference between the two systems is that <B>hot runner eliminates the excess material</B> retained in the feed channels of a cold runner mold. This feature: <OL> <LI>Reduces the number of production steps required <LI><B>Saves in material, labor and energy costs</B> </LI></OL> <H3>Hot Runner Molding vs. Insulated Runner Molding</H3> <P>Hot runner molding yields the lowest cost per finished part, but <B>hot runner molds can be very expensive to build</B>. <A class=norm href="http://www.acmolders.com/insulated-mold-acm.htm">Insulated runner molds are an excellent option when a large number of plastic parts need to be manufactured quickly</A>. <P><B>Insulated runner molds are less expensive to build and maintain</B> than hot runner molds, easy to clean and change production colors quickly, and provide faster molding cycles and improved part finishes. </P> <P> <TABLE class="" width="100%" border=0> <TBODY> <TR bgColor=#d9d2c3>
