Cap torque for induction sealers
Aug 17th, 2009 | By Mark Plantier | Category: Operating TipsFor induction sealers to successfully seal containers proper cap torque is critical. It is estimated that over 80 percent of all induction sealing problems are related to torque issues.
Induction sealers rely on cap torque to provide the consistent down pressure to hold the induction seal in place during the heating and sealing process. Operations that cap by hand must be careful to ensure adequate cap torque.
The chart below provides the reccommended torque requirements for induction sealing containers of various sizes.
For more information on factors that can affect the success of your induction sealer please read the White Paper Achieving a Perfect Seal Every Time.
