Celina works with customers every day providing them contract fabric welding services. We currently offer four types of welding to our customers: Hot Air, Hot Wedge, Ultra Sonic, and RF (Radio Frequency) Welding.

Celina has the capabilities to weld virtually any thermoplastic material on the market today. Our state of the art equipment and facility enables Celina to be very competitive while manufacturing our customer’s products.

Forsstrom Traveling Gantry Welder

This traveling machine increases efficiency by reducing material handling. The opera¬tor works on the platform behind the ma¬chine and travels with it as it moves along the 5’ x 100’ table. This machine is suitable for large products with long, straight welds. It is also used for products that require multiple welds in a small area. Multiple fabric components can be laid on the table with the welding dies. The programmable RF head travels and completes multiple welds in one pass, maintaining consistent welds via the solid state monitoring controls.

Bar Sealer

The most common RF Welding machine at our facility, the bar sealer is equipped with long straight bars ranging from 1” x 13” up to 2” x 48”. This equipment enables us to do long straight RF welded seams of various widths.

Platen Sealer

These machines have a large 24” x 48” top plate. This large plate allows us to place a variety of different die shapes and sizes between the welding bed and the top plate to achieve endless weld shapes. Common uses include attaching reinforcement patches, multiple-layer paraphernalia such as expansion joints and door ties, and small seals easier to make without using a larger hot air sealing machine.



This machine is a proprietary piece of equipment that has been custom designed to seal up to 13 seams at once. It was developed for high volume large panel production runs in an effort to better meet Celina Industries’ customer quality and delivery requirements. In addition to the multiple sealing capabilities the machine is equipped with an electromagnetic brake system on the unwind stands, computerized programming and an automatic cutter. The M-100 can also apply supplementary reinforcement materials to sections that may be exposed to excessive stress/ wear.


Utilized for large-volume orders, the Turntable Welder has a rotating bottom sealing plate to keep work flow moving. Product can be pre-positioned on areas next to the main weld area, to be moved into the machine as the table spins. Multiple sealers can be moved to utilize a single table, effectively turning the Turntable Welders in an effective multi-sealer.


With a focus on productivity, Celina’s Shuttle RF Welder allows for near constant machine production time. Two welding jigs means twice the work completed; while the machine is using radio frequency to seal materials together, the operator can safely prep the next pieces. The jigs are then swapped, and while the next seal is created the operator is removing the finished material and replacing it with new product.

Hot air welder

This process is used to join thermo plastic industrial fab­rics & films utilizing hot air & pressure. Heat tem­peratures can range from 1000˚ to 1375˚. Heated air comes out of a nozzle directed at a silicone or steel pressure wheel, the combined heat and pressure causing the materials to be sealed together. Machine lengths range from 20’ to 60’, though overall machine length does not limit the size of the product.

Hand Held Heat Sealer

Celina’s employees have been trained to use hand held heat guns. During this process the worker takes the gun which blows hot air out of a nozzle, and places it between the materials they are welding. Then they begin moving down the weld following it with a silicone hand roller. This is a skilled position that takes a significant amount of training.

Hand held Ultrasonic Welder

In addition to radio or high frequency welders, the hand-held Ultrasonic Welder allows us to create small tack welds in a fraction of the time it would take on a full sized machine. Compact and portable, the Ultrasonic Welder increases the efficiency of our assembly process by decreasing part alignment time on our larger welders, and ensuring better product configuration when dealing with multiple layers of materials.


This machine is most effective in creating heat sealed seams, reinforced strips and various lengths of material that can be combined or reinforced. With an automated material roller to collect finished materials onto spools, this machine conveniently creates and stores strips created on it.


The T-100 Miller Welder is a hot air welding machine which specializes in creating circular seals. Its adjustable arm allows for straight seams and also for the creation of rounded tubes for items like air ducts.

SEWN Seam Taper

This machine lets us attach a layer of heat-bonded tape over sewn seams to increase their ability to be water resistant. Waterproofing seams keeps covered products dryer and increases the overall life of the material by not allowing water into the material layers, thus preventing the growth of mold and mildew.
