What is RF Sealing? How does it work?
RF Welding ( Radio Frequency Welding ) machinery usually called
RF Heat Sealers are used to bond a variety of plastics. A RF
Sealer operates similarly to a standard kitchen microwave oven.
When the RF is applied it excites or agitates the polarized
molecules in the plastic causing heat. When pressure is applied
to the plastic the molecules of the two layers flow together. The
resulting bond is usually stronger than the individual layers of
material. RF Welders and Sealers usually operate at 27.12MHz.
What are RF Sealers primarily used for?
The Packaging Industry uses RF Welding to bond ClamShell and
Blister Packages. The Medical industry use RF Sealers to make
Blood Bags, IV Bags, Pressure Cuffs and many other similar
products. In the Automotive Industry RF sealers are used to make
the Roll-out Luggage Compartment Covers and to RF weld the vinyl
"Toe" and "Heal" pads found at the feet of the Automobile Carpet.
RF is used in many industrial application to make items such as
vinyl construction road signs

What do you need to know before you buy a New or Used RF
1. Your materials must be compatible with RF Sealing. Not all
materials respond to RF Heat Sealing. Check the "add link to
materials compatibility chart "
2. Next you'll need to consider sizing the RF Sealers power supply.
RF Sealers are sized in Kilowatts. The most common sized RF
Heat Sealer is 10KW and 12KW units. The basic rule of thumb is
that a RF Sealer can weld approximately 3 to 5 square inches per
Kilowatt. Therefore, theoretically a 10KW RF Sealer can weld
between 30 and 50 square inches of seal area. However, there
are loss factors at work so get assistance from someone who has
experience sizing RF Sealers or RF Dies and RF Tooling.
3. The RF Sealer 's press size is the next area to consider. The
physical size of the press directly relates to the size of the item(s)
being RF Sealed. If you need to RF Seal a blister or clam shell
package you'll need a press size that is large enough to cover that
blister or clam shell package at least once. The presses are
described by the size of the press plate that the RF Tooling or RF
Die mounts to. The most common size press is 20" x 30". Some
materials require preheating. Not all RF Sealers have this
capability, but in most cases heaters can be retrofitted to an
existing press. So you'll need to know if the material you using
4. Finally, you'll need to consider the material handling system for
your RF Heat Sealer. Some RF Sealing equipment have large
turntables or shuttle systems mounted directly the RF Sealer 's
frame. The turntables rotate automatically allowing a multiply
operators access to loading and unloading stations called Nesting
Plates (lower half of a RF Die set). Most shuttle units require the
operator to manually index the shuttle in and out of the RF press
area. However, some RF shuttle units are power by air cylinders.
Here again we recommend getting assistance from a professional
experienced in RF Sealers or RF Tooling / RF Dies.
