Universal Coil Specifics
The Universal coil from Pillar is fitted at an angle to the conveyor, meaning that the closure and bottle to be sealed pass under the sealing head at an angle. The dwell time and electromagnetic field created are more than sufficient to activate the heat-seal on the foil and form the necessary bond. This method is successful even with more complex caps such as child resistant closures (CRC's).
The fact that customers need only one coil size to seal a wide variety of closures reduces capital and operating costs, eliminates maintenance downtime necessary for coil changes and offers a greater degree of flexibility within the induction process.
In addition to the obvious benefits associated with this flexible approach, all Pillar coils are fitted with an innovative “Quick-Lock” mechanism, enabling easy disconnection and removal from the unit for servicing, a factor made simpler still as the sealing head is totally independent from the power supply.
Pillar is also the only company offering a coil refurbishment service for the repair and servicing of damaged or heavily used sealing heads, further reducing the ownership cost of the induction process on the packaging line.
