Custom Product Manufacturing

Custom product manufacturing helps industrial design companies turn innovative ideas into real prototypes and products.

You need a contract manufacturer you can trust, with expertise in both materials and the manufacturing process—a manufacturer with a commitment to quality.

In other words, you need SealWerks. As custom plastic products manufacturers, we’ve
developed products for medical, industrial, government, and military applications with
exacting standards of quality.

Your Custom Manufacturer

Our deepest expertise is in flexible containment as well as inflatable and protective products.

We can manufacture:

Lifting cushions and bladders
Flexible fluid reservoirs
Medical collection bags
Uniquely configured air bladders
Flexible bellows and way covers
Gel-filled therapy pads

Before you commit to a full manufacturing run, we can help you with product prototyping and design consulting. Use your prototype to test and refine designs. Once you’re satisfied, we can deliver a full production run.

Heat Sealing and RF Welding

Using heat sealing or RF welding we can connect tubes, hoses, and other special features into plastic and plastic-coated products. Both processes create strong bonds to form a durable, air-tight, and leak-proof seal without the use of added chemicals. These qualities make heat-sealing and RF welding ideal for medical products.

We can use these processes to connect tubes or hoses to air bladders or medical collection
bags. Tubes inserted into the material become part of the design, adding functionality to the
product.

Thermoforming and Vacuum Forming

Thermoforming or vacuum forming are ideal for food service and medical devices. By heating and shaping plastic on a mold, we can create custom cushions, trays, bins, or medical imaging equipment covers and cases.

Industrial Sewing for Product Finishing

One of our specialties is heavy-duty sewing to finish welded and heat-sealed products. We can add grommets, velcro tabs, zippers, or other fasteners to a wide range of materials and products. Ideal for protective covers, bags and cases, or cushions.

Materials In Custom Manufacturing

Quality product design starts with the right material. Our materials engineers have expertise in the following materials:

Low-density polyethylene (LDPE)
Polypropylene (PP)
Polyethylene (PE)
Acrylonitrile-Butadiene-Styrene (ABS)
Polyethylene terephthalate (PET / Polyester)
Kydex
Thermoplastic polyurethane (TPU)
TPU Coated Nylon / Polyester
DEHP free PVC

Our materials engineers stay up to date with the newest materials to help you make the right choice for your product. We take into account product use, durability, budget, and regulatory guidelines to meet your needs.
