Keep Your Injection Molding Process Stable and Repeatable with Laminar Control
ELK GROVE VILLAGE, IL, October 29, 2021 - One of the best ways a molder can ensure quality parts consistently is by understanding and improving upon the injection speed process.
Shibaura Machine’s all-electric injection molding machines offer a Laminar Control function which helps alleviate issues when running a “pressure limited” process. What is a “pressure limited” process?. When the resin pressure rises during the filling process and reaches the filling pressure setting (PI), shifting from speed control to pressure control. The filling at constant pressure means uncontrolled filling speed creating inconsistencies in the repetition of the deceleration of the speed filling the cavities. The Laminar Control internally records the filling speed deceleration pattern and controls the filling speed so that it follows this pattern. This stabilizes the repeated filling speed when under pressure control.
Laminar Control Improves Shot-to-Shot Repeatability and Part Quality
At a glance, the Laminar Control function takes a snapshot of the injection speed profile of a good shot. The control records the injection speed profile in the internal memory and filling speed is controlled in accordance with that filling speed profile. When controlling the filling speed, the segment start position to the transfer to hold position is divided into 100 filling speed stages. This recreates the curved deceleration pattern shown below.
