OnPak is an ultrasonic clam shell sealer that seals clam shells quickly and safely using ultrasonic waves. It is simple and easy to operate. Just turn on the machine, set the timer dial, and spot weld using the hand set. No warm up time needed. Easy to operate.
Ultrasonic is the 'higher technology' relative to constant heat sealers. With constant heat, your sealer has two heating elements that are always on, and the unit has a 'warm-up time' when you first turn it on. As you seal using constant heat in high production environments, you may find that you have to stop to allow the heating elements to regenerate heat. Constant heat also has more of an 'art' to the sealing method, with many sealers only having a 'high' and 'low' setting.
The Onpak ultrasonic sealer sealing points use high frequency vibration that causes the plastic to melt & create a seal. There is no 'warm-up time' for this unit, and after you seal the jaws will begin to cool. The dial on the front adjust how long the jaws vibrate for different types of clamshells.
Note: The manufacturer does not recommend interchanging handsets between bases. Interchanging handsets may lead to product failure that will void all warranties. Warranty is also voided if the handset is closed without a clam shell present to be sealed.
We highly recommend having your clam shells tested before purchase. We enjoy working with our customers, and will make an unlisted YouTube video showing you the results of this machine & your clam shells.
