Hot Runner Systems or Injection molding;
The cost savings, when using hot runners can be substantial,
and the part quality is very often much better than cold runner. Usually when
the quantities of the injected molded parts are large enough hot runner systems will
be used and their cost can be verified.
With the increasing improved technology of today's injection
moulding systems, the use of hot runners is becoming an industry standard .
Many applications simply are not possible with the old
standard sprue and cold runner system, and hot runners offer a great way to
maintain uniform wall thickness and eliminate knit lines and flow lines.
What are advantages of hot runner systems?
Less waste
Ability to minimize gate vestige
They create uniform wall thickness
Reduction or elimination of knit lines
Great for high cavitation molding
Often the only method for micro-molding. The center to
center distance of the hot runner tips is as little as 17 mm.
Standardization of components can mean significant savings
in material and manufacturing.
Many large molds rely exclusively on hot runners.

What about the maintenance of hot runners?
Hot runner systems require a new level of
expertise on the part of the mold maker. However, this does not mean that it is
overly complicated or highly specialized. A well designed system is relatively
free
from maintenance, once it is properly installed.
It can, and does happen, that mold makers become frustrated
with these systems and swear that they are too much trouble. This is usually
due to the fact that the system is not properly installed or incorrectly
operated in the molding process.
The leading system manufacturers have a well-trained team of
specialists on hand to assist in the proper installation and operation of the
systems. The time spent listening to these specialists is time well spent!
Are there different types of hot runner systems?
There are almost as many types as there are suppliers! Most
share some common features, however. There are sprue gated systems, valve
gates, tip gates (the most common), and edge gates. Any of the major suppliers
can describe in great detail why their system is the best for your application.
Hot runner systems are some of the most important mold components
What are the benefits on the longer term
Even though there is an small start capital necessary to invest in a hot runner
systems, it is very easy to justify the long-term benefits. Without increasing the
complexity of the design of the mold, a hot runner equipped mold can
significantly reduce costs. Because the hot runner is designed and manufactured
independently, yet concurrently, the lead times are not affected.
Mold makers should always suggest methods forhis customer to reduce molding costs and increase the output of the mold. Being
knowledgeable with various runner systems is a good way to demonstrate an
active role in helping the molders bottom line. This in turn makes the
likelihood of increased business
even greater for the mold maker.
