Integrating heating and cooling into the mold helps improve injection-molding control and flexibility.
An upgradable approach to flow-control technology offers flexibility and could help ease the decision on whether the technology is worth the investment.
Eliminating hesitation marks is easier and more cost-effective with multi-speed hydraulic technology.
Alternative venting valves can help overcome standard mold venting limitations and improve mold performance.
Developing basic cleaning and repair skills among in-house technicians should be the goal of every shop that runs hot runner systems.
For large injection-molded parts, a servo-driven valve gate system can improve surface finish and part performance.
An easy way to get a snapshot of how a mold is operating is to run regular mold scans via a hot runner temperature controller.
Incorporating multiple-gate nozzles means smaller molds, small presses, a balanced fill rate, reduced residence time, temperature control and design flexibility.
Keeping hot runner system costs down is key to efficient injection mold design.
Mold builders and molders should carefully consider hot runner selection, as it dramatically impacts an injection molding system’s speed, quality and uptime.
