Our advanced manufacturing facilities include a wide range of thermoplastic injection molding solutions for many types of plastic parts, including processes for Hot Runner Systems and Cold Runner Systems.
Each runner system offers advantages and disadvantages. Choosing the system to employ depends on the requirements of the part to be produced. A few of the considerations include:
The primary difference between the two systems is that hot runner eliminates the excess material retained in the feed channels of a cold runner mold. This feature reduces the number of production steps required and saves in material and energy costs.
Furthermore, hot runners use only 100% virgin resins; no reprocessed or “re-grind” material is added. This is an important feature for specific applications where regrinding can cause the material to yellow, or detracts from the material properties, such as clarity in light pipe or lens production, where long-lasting transparency is a specific requirement.
Hot runner systems shoot melted material directly into individual cavities. Hot runner is a more expensive process than cold runner systems, almost always used for large volume production of thermoplastic injection molding parts, or multiple part production using multi-cavity molds and stack-molding technology.
Hot-runner systems are almost always used when large runs have to be manufactured in highly automated production. Additionally, technological advances enable us to build molds with gates positioned to yield the best quality molded parts.
Hot runner molds are usually connected to needle valve nozzles, which are activated with precise computer-controlled timing. This allows for a number of advanced processes, including:
Primary advantages of hot runner systems include:
There are, however, a few disadvantages to hot runner systems that need to be considered:
