Seal the Deal

Packaging applications present some unique problems. Among the biggest challenges for Dalton Electric are uneven heating, repeated flexing of the wire / termination and sealing against washdown or product contamination. We have been talking about the advantages of the continuous coil in the Watt-Flex® cartridge heaters, and that comes to play with this concern in a big way.

The flexing and sealing aspects of this application are addressed with our MW transition. The right angle header is welded around on the heater to form a seal. A rigid piece of tubing extends off the header with a specially prepared crimp near its end.

A very flexible cable is used that consists of a twisted pair of wires, each insulated with a primary teflon extrusion. This pair is then over-extruded with a silicone jacket, sealing the wire but allowing great flexibility and resistance to breakage. This wire is terminated and crimped into the tube extending from the header, stabilizing the termination from repeated flexing.

Completion of the sealing process is accomplished by RTV potting the entire header and application of a meltable wall shrink over the entire transition. Packaging problems are generally eliminated with this transition from heater to wire, again reducing your customer's cost of heating.

Friday Funnies

In surgery for a heart attack, a middle-aged woman has a vision of God by her bedside. "Will I die?" she asks.

God says, "No. You have 30 more years to live."

With 30 years to look forward to, she decides to make the best of it. So since she's in the hospital, she gets breast implants, liposuction, a tummy tuck, hair transplants, and collagen injections in her lips. She looks great !!!

The day she's discharged, she exits the hospital with a swagger, crosses the street, and is immediately hit by an ambulance and killed.

Up in heaven, she sees God. "You said I had 30 more years to live," she complains.

"That's true," says God.

"So what happened?"

God shrugs. "I didn't recognize you."
