"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.

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 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."

1. Prototype and final tooling drawings are produced from sketches or AutoCAD files by Sealtech draftsmen. These tooling drawing are used to fabricate in-house tooling/dies for production. From there, dies are used to produce a manufactured prototype that is sent to the customer for approval. 3. The most important stage in manufacturing your product is dielectric sealing. Sealtech has machines ranging in size/power from 4KW to 240KW.
2. Once a design has been approved, final tooling drawings are completed and production tooling/dies are made to produce first article sample. Sealtech fabricates selected materials to form products ranging in size from 1" x 1" to 5.5' x 12'. After first article samples are approved by Sealtech's Quality Assurance Department they are submitted for final customer approval. 4. Quality Control operates independent of production, sales, and engineering to provide objective evaluation of materials, processes and finished products. Test data is collected, recorded and compared to customer specifications to provide evidence of product conformance throughout the set up and production process. Sealtech produces Production Process Packages for each product to provide a visual pattern for each stage of production. In this manner, you will be guaranteed the Sealtech excellence in manufacturing at every turn.

We can fill your needs with custom components manufactured from vinyl, vinyl coated nylon, urethane, urethane coated nylon,
ethyl vinyl acetate or other exotic materials.

Sealtech has the engineering, manufacturing, and quality assurance to carry your project from concept to consumer.

We specialize in RF sealing, RF welding, dielectric sealing, dielectric welding, heat sealing, and heat welding.

SEALTECH leads the way
