Plastic/Vinyl
Shrink Tubing for Brake Lines
Fostoria's
lab testing capability allowed different oven configurations, power
densities, and designs to be experimented with. Combining this with
their extensive infrared background, Fostoria engineers were able to
develop a design that exceeded all requirements. The
final design incorporated instant on & off T-3 quartz lamps. The
oven requires little heat-up time, responds to process changes
extremely fast, and can be de-energized instantly if needed.
Customized controls and oven circuitry allow the heated footprint of
the oven to be easily modified to match the location of the shrink
tubing. To lower operating costs, the heat sources are de-energized at
areas where shrink tubing is not located. The oven was also divided
into multiple heat zones that utilized SCR power controllers. The
infrared output of each zone is infinitely variable from 0 to 100%
which allows the operator to match the heat output of the oven to the
needs of the product. To
help eliminate air bubbles, Fostoria's engineers angled the infrared
emitters so that the heating began at one end of the brake line and
shrank the tubing continually up the line, creating a consistent
bubble-free finish. A design was also developed that automatically
loaded the brake line from the forming machine onto the infrared oven
conveyor. These features resulted in an oven system which met all the
customer's unique design requirements.

Fostoria
Industries, Inc. was approached by a company that specializes in the
fabrication of metallic and extruded tubing for the automotive market.
This company had a need for an infrared oven to heat shrink tubing on
automotive brake lines. This application presented Fostoria with
several unique challenges:
