What is Solvent Bonding?

Solvent bonding is a sealing process through which multiple pieces of material are bonded using a strong solvent. The solvent used to bond the materials together works by temporarily softening and dissolving the material.

How proper metal finishing treatments prevents foodborne illnesses in Food Processing and Packaging Plants?

The US Department of Agriculture (USDA) and the Food and Drug Administration (FDA) oversee safe operations at food processing and packaging facilities. These regulatory agencies control the supply of meat, poultry, eggs and other food products.


RF Welding is an electrical process that permanently bonds a select group of like materials together.

Commercial sewing is stitching of large quantities of units in the same configuration.

You should have an image of drawing that conveys as much about the overall construction as possible. Also approximate dimensions.

We can guide you through the design-development process if you can visualize the appearance and functionality of your new product.

When radio frequency welds are done properly, they will remain welded as long as the original material lasts.

Radio Frequency (RF) Welding is a clean process that does not include any additives. RF welded seams will last as long as the product itself lasts.

If your product needs to contain liquid or air and is made from an RF sensitive material, RF welding will work well for your product.
Health Care, medical equipment manufacturing, aerospace and food processing to name a few.
In most cases the material(s) dictate the sealing process. If you are unsure of the best materials, a good starting point is the intended product function.

Solvent bonding is a bonding process through which multiple pieces of like materials are permanently affixed to each other using a chemically compatible solvent.

RF or heat weld 2 sheets of polymer/polymer coated fabric together in the shape/size you want. Weld on one or more ports to connect tubes. The completed unit will be shaped like a flat pillow with protruding seams around the perimeter.
With a straight port welded to a flat surface on the bladder. For larger bladders, a two piece bulkhead fitting with NPT threads may work better.
A safe level of pressure for most bladders constructed from a fabric reinforced material is approximately 15 psi or ~1 Bar. There is substantial latitude of that pressure value with different sizes, constructions and configurations.
We are capable. The items must be completely clean and dry, like new material would be. Typically the cost to repair is more than people think.
Yes, we can. Please be prepared to share information about the intended application and the environment that the product will be subject to.
STEP, DXF or DWG drawing files will work well for us.
We do fabricate plating tank liners. We do not repair plating tank liners.
Bellows can be fabricated with separating zippers or velcro closures for ease of installation or equipment maintenance.
The thinnest material we can work with is .002″ thick.
Some fabrics can be heat or RF welded if they have a heat or RF sensitive coating on them.
Flex cycle life depends on material range of flex and the environment that the item is functioning in. An average flex cycle life for .010″ thick TPU film is approximately 500,000 cycles.
