Using Auto-Purge to Improve Injection Molding Efficiency

  • Injection Molding

ELK GROVE VILLAGE, IL, June 23, 2021 - Molders today are always looking for a way to minimize their losses.  So while purging is often necessary, it makes many molders cringe because this process often means costly waste and lost production time- defeating the purpose of improving their bottom line. 

Automating the purging process can not only save time compared to conventional purging, but makes it possible to extend the time between required maintenance for the mold and improve overall efficiency. The auto purge feature on the V70 controller by Shibaura Machine plasticizes materials newly inserted into the hopper when exchanging materials in the injection molding machine, and automatically performs the operation of purging residual materials in the barrel without changing the production set-up data. 

Dramatically Improve Efficiency

The V70 controller’s auto purge feature helps molders realize several benefits after a purge. Fewer scrap parts, less carbon build-up in the barrel, elimination of color hanging up in the tool, and reducing changeover time means not only less downtime, but a dramatic improvement in efficiency. 

The auto purge feature offers three types of operations to choose from:

  • Program purge mode where purging is performed according to pre-programmed settings;
  • Screw speed purge mode that rotates the screw for the set time;
  • Customized purge mode which is a combination of the four operations of screw advance, charging, rotating in place, and screw retract.

Additionally, the auto purge feature has several options that make it incredibly user-friendly. Molders have the ability to save up to 50 pre-saved programs that can be material specific, utilize a rotate in place feature, and choose from several modes including: cavity purge, shut off nozzle, and valve gate.
