RF Sealing

Sealtech leads the way in RF Sealing by providing skillful engineering, sophisticated manufacturing, and the quality assurance you need.

RF Sealing

Sealtech RF Sealing was founded in the early 70s, to serve the needs of the Nuclear and Recreational Industries. Having a reputation for quality production and exceptional engineering support, Sealtech was purchased by one of their customers in 1983 and moved from Colorado to Tennessee. Now self-contained, PI, Inc expanded Sealtech’s use of RF Sealing and developed additional business in the Medical, Military, Automotive, Aerospace, Safety, and Seating Industries.

“The vibrant collection of items found in this website illustrates the technology of radio frequency welding/dielectric sealing. But if you take each item individually, then this collection represents the experience and expertise you will find at Sealtech.
SealTech RF Sealing
We manufacture products using urethane, vinyl, or other exotic materials for:
– Aerospace/military
– Medical
– Automotive
– Recreation
– Safety and seating uses

We ultimately manufacture products that save lives, sustain life, or make living more pleasurable.

The G-suit we manufacture for the military must function as flawlessly in extreme environments as the medical respiratory bellows in an anesthesiology machine. Whether it’s buoyancy compensators, hydration bladders, lumbar supports, decontamination suits, industrial cooling vests, eye exam chairs, or sonar buoys, Sealtech understands the importance of the product and leads the way in terms of practicality, functionality, and durability.

I invite you to call me and let the Sealtech RF Sealing team bid your project. We fabricate components as small as 1″ x 1″ to large surface welds of 5′ x 12′. We manufacture simple components or respond to the demand for complete product manufacturing requiring contract subassembly work. Whether you have an intricate AutoCAD/CAM file or a rough sketch on a napkin, Sealtech leads the way by providing skillful engineering, sophisticated manufacturing, and the quality assurance you need.”

RF Sealing Capabilities

RF Sealing also known as High Frequency welding or Dielectric Sealing is a method of joining thin sheets of polar thermoplastic material together. It uses high radio frequency (13 to 100 MHz) electromagnetic energy to fuse the materials together on a molecular level. Sealtech offers the following capabilities to their RF welding services.

  • 1″ x 1″ up to 5′ x 12′ RF Sealing Part Capabilities
  • Silk Screening
  • Pad Printing
  • Sewing
  • Product Retail Packaging
  • Thermoforming
  • Part Prototyping
  • In-House Design/Engineering
  • On-Site Tool Room
  • Warehousing Capabilities
  • FDA Certified
  • ISO 9001:2008 Certified

RF Sealing Materials

With over 2o years of RF Welding experience we are well versed in all seal-able materials available. What types of plastic can be RF welded? Plastics that can be welded are called “thermoplastics” which simply means that when properly heated to a sufficiently high temperature, they will soften and therefore can be rf welded together. The most common types of thermoplastics are Polyethylene, Polypropylene, Polyvinyl Chloride (PVC), Polyurethane and Acrylonitrile Butadiene Styrene (ABS).
