5 Ways to Reduce Injection Molding Start-Up Scrap with Shibaura Machine’s ECSXIII Series

  • Injection Molding

ELK GROVE VILLAGE, IL, July 15, 2021 - When it comes to improving your injection molding process, reducing scrap at machine start-up is one of the more effective ways to increase efficiency. With costs rising on materials and shortages throughout the industry, optimizing your start-up processes in order to reduce scrap will not only improve production efficiency but decrease your carbon footprint and the associated costs.

The SXIII injection molding machine by Shibaura Machine allows manufacturers a solution to reducing start-up scrap with five easy to use features. By focusing on controlling scrap, manufacturers can better focus on remaining competitive and maximizing their benefits.  

SXIII Injection Molding Machine Features to Reduce Scrap

In order to offer an easier and more effective solution for the reduction of start-up scrap, the team at Shibaura Machine designed these features within the SXIII technology:

  • Dry Cycle Mode: This function is selectable with one button. The machine will run in dry cycle mode to ensure mold movements are correct to minimize start-up cycle interruptions.
  • Dynamic Self Tuning (DST) Press: To ensure the correct tonnage is applied as the mold expands due to thermal expansion, the DST-Press function is put in place. This control allows for the strain gauge on the tie bar to measure actual clamp tonnage and the machine can adjust on-the-fly to maintain the proper tonnage to eliminate short shots and improve venting during start-up. 
  • Start-Up Feature: This easy to navigate interface allows users to utilize a soft start program and have it act consistently. Users can pre-set a certain number of shots at start-up where the machine injects at a lower speed, position, and pressure, while gradually ramping up to production settings. This allows the process to stabilize while minimizing the amount of start-up scrap.
  • Auto Purge: Ensure the material is ready for production by eliminating black specks and degraded material by running the auto purge program prior to start-up. Users can set up this feature to run at the end of production and/or before a new production run.
  • Back Pressure in Manual Mode: This feature helps eliminate the potential for human error and inconsistency, while ensuring the back pressure in auto remains at the right parameter. There is a separate screw back pressure setting for manual mode. This prevents the user from having to change the production back pressure setting for manual purge and having to remember to put it back before running automatic, thereby preventing potential start-up scrap parts.
