If you are using cold runner systems,
you can continue with technologies a decade old. However, when it comes to
producing simple or complicated, small or large products with fine dimensional
tolerances, superior strength and high quality finish, only hot runner molds
will serve the purpose. There is less wastage, less consumption of energy and
faster, high volume production through this route. The only drawback is that
hot runner molds can be terribly expensive and must be made using the best
design and materials in hot runner technology to perform
reliably and last for a long time.
Hot runner system suppliers are
constantly refining design and manufacturing techniques. You can see this in
the way molds have more cavities than ever packed in to a smaller size. This is
achieved due to advanced in nozzles such as the pin point gate, single tip and
multitip point gates, sequential multi-tips and similar sophistication. Along
the chain there have been improvements in manifold design and construction to
ensure even distribution of heated material. German hot runner heaters have a
reputation for reliability and when used with intelligent temperature
controllers with computerized PLCs, assure high performance. The point is not
to view the components in isolation but to consider that the parts make up the
whole and perfect integration of technology and components define the mold, its
performance, cost and durability.
Competition is intense and only superior, advanced technology from
well-established system designers and manufacturers helps you stay ahead.
Instead of looking to European or American suppliers, look at some Far East
manufacturers who have put it all together in a sophisticated, affordable
package.
