How It's Made
Sometimes an application calls for tubing to bend around equipment or fit into a certain area. And it may accomplish that just fine on its own. But depending on the type of tubing material being used, it could kink, or excess tubing may get in the way of an operator or other equipment, or it might simply look unprofessional. That's where heat-formed shapes can help.
Custom shapes such as elbows, multiple bends, flared ends, curves and coils can be manufactured. Several types of plastic tubing material can be heat formed including PVC, polyurethane, nylon and fluoropolymer. In most cases both unreinforced tubing and braid reinforced hose may be heat formed. Even short, simple pieces with a single elbow can improve a product. There's no loose tubing to get in the way, and the formed pieces can ease tubing installation.
Here's how it's done: During or after tubing extrusion, pieces are cut to a specified length. The tubing is placed onto special forms to achieve the desired shape. Many forms already exist at NewAge Industries, but new ones can be created to meet customer specifications. The forms with their tubing then go into an industrial oven. The type of material being formed determines the temperature and length of baking time.
Once the forms are removed from the oven, they're placed in a cold water bath to complete the heat-setting process. The formed tubing pieces are then removed from the forms, ready for air drying, packaging and shipping.
