Heat and Bend Acrylic Parts

A manufacturer of acrylic developing a method for customers to heat the acrylic prior to bending it into shape.

Poor Quality

Existing metal tubular heaters were causing distortion and stress at the bend area.

Delayed Start Up

The existing metal tubular heaters took too long to reach operating temperature.

Heat Absorption Characteristics

Acrylic absorbs energy best at 1.15, 3.2 and 3.5 microns. The existing metal tubular heaters had a peak wavelength emittance of 3.4 microns and a negligible amount of energy at the 1.15 micron level.

Excessive Energy Consumption

When production stopped, the existing heat source continued to consume energy at in-production rates.
