Practical tips for reducing cycle time without compromising part quality in injection molding.
The Importance of Cycle Time
In injection molding, cycle time is directly tied to profitability. Reducing cycle time by even a few seconds can significantly increase daily output and reduce the unit cost of production.
However, optimization must be balanced with quality requirements to avoid defects such as warpage, sink marks, or short shots.
Cooling Time Optimization
Cooling time typically represents the largest portion of the total cycle time. Optimizing mold cooling channel design (such as conformal cooling) and ensuring adequate chiller capacity can dramatically reduce the time required for the part to solidify.
Machine Upgrades
Upgrading to all-electric machines, like the LK Elettrica series, allows for parallel movements (e.g., ejecting while the mold is opening or plasticizing while cooling), which can shave valuable seconds off every cycle.
