As a semi-automatic, straight line, six spindle machine, the SK600 Cap Tightener & Retorquer can handle all standard cap torquing applications. It is perfect for tightening Pumps and Trigger Sprayers where automatic insertion of the pumps and triggers is not feasible. When used after an induction sealer, the retorquer ensures that caps are properly torqued. The machine is also available as a Press-On Capper. As your business grows, you can upgrade the Tightener to a fully automatic Capper.
