135. Hot Runner Systems for Plastic Injection molding

The using of hot runner systems is increasing due to the fact that they provide a more efficient method of plastic molding parts. The cost savings can be substantial, and the part quality is much better than a cold runner system.

With the increasing sophistication of today's plastic molds, the use of a hot runner system is becoming an industry standard. Hot runners offer a great way to maintain uniform wall thickness and eliminate knit lines and flow lines.

Advantages of hot runner systems
Ability to minimize gate vestige
Uniform wall thickness
Lower cycle times
Less waste
Reduction or elimination of knit lines
Great for high cavitations molding
Standardization of components can mean much savings in material and production tooling.
Many large custom molds rely exclusively on hot runners. Cold runners cannot meet the demands.

Maintenance of hot runner systems
Hot runners systems need a new level of expertise on the part of the mold maker. But this does not mean that it is overly complicated. A well designed system is relatively free from maintenance, once it is properly installed.

The leading hot runner system manufacturers have a well-trained team of specialists on hand to assist in the proper installation and operation of the systems. The time cost listening to these specialists is time well spent!

Long term benefits
Even though there is an initial investment with hot runner systems, it is easy to justify the long-term benefits. Without increasing the complexity of product 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.
