Key Differences and Considerations:
-
Hot runners maintain the plastic at a consistent temperature throughout the runner system, minimizing material waste and reducing cycle times. Cold runners, on the other hand, allow the plastic in the runner to solidify, requiring it to be removed and potentially recycled.
-
Cost and Complexity:Cold runner systems are generally less expensive to manufacture and maintain than hot runner systems due to their simpler design.
-
Cycle Time and Efficiency:Hot runner systems typically offer faster cycle times and higher production efficiency due to the consistent temperature and reduced material waste.
-
Material Waste:Cold runners can result in more material waste as the runners solidify and need to be removed, whereas hot runners minimize waste by keeping the plastic molten.
-
Part Quality:Hot runner systems can offer better control over the injection process, potentially leading to higher quality parts with fewer defects.
-
Applications:Cold runner molds are suitable for a variety of applications, especially where cost is a primary consideration and the cycle time requirements are not extremely tight.

What is cold runner in injection molding?
A cold runner injection molding system consists of two or three plates for the mold used to inject plastic through the sprue and feed the runners that lead to parts in the mold cavity. To put it more simply, cold runners are
unheated molds and channels used to inject molten plastic into a mold tool cavity

What is a three plate Mould cold runner?
A three-plate cold runner system is
similar to the two-plate system.
However, the three-plate injection mold is flexible with an additional runner plate
. Furthermore, there is no need to cut the runner from the injection molded part, and the mold does not require an ejection system for part removal.
