KS-4000TAS Series

2-station, 4KW, Shuttle Type RF Sealer Clamshell Packaging Machine



Our KS Series two station floor model shuttle type RF sealing machines are ideal for low to medium volume or JIT production.  These units can achieve speeds of up to 8 cycles per minute using one or two operators.  These high-quality, budget friendly RF sealing machines are ideal for start-up operations, cellular manufacturing or back-up equipment.  The KS Series are designed to accept packages that have been assembled off-line to be loaded and unloaded by hand.  The sealing cycle is automatic.  Packages may be sealed and trimmed (tear seal) or sealed only depending on the tooling style purchased.


The operator(s) load the pre-assembled clamshell packages into the sealing fixture which is then rolled between the upper and lower electrode.  The sealing cycle is started automatically when the seal tray reaches the end of its travel.  At the end of the sealing cycle the operator withdraws the tool from between the electrode, unloads the sealing fixture and reloads with another unsealed clamshell package.  A second station is provided at the opposite side of the machine for a second operator to produce packages when the electrodes are vacated by the first operator.  A single operator can work both stations if necessary.
