Description
|
|
The MI Band is a high performance
heater. Its performance and name are derived from Watlow's exclusive
mineral insulation material that has much higher thermal conductivity
than the mica and hard ceramic insulators used in conventional
heaters.
A thin layer of the "high" Thermal conductivity used
to MI material is electrically insulate the element wire from
the inside diameter of the heater sheath. A thicker, "low"
thermal conductivity layer backs up the element wire, directing
the heat inward towards the part that is being heated. The result
is more efficient heat transfer... a performance solution that
lowers element wire temperatures and increases heater life

Features
|
|
- Heater operating temperatures to
1400F (760 C)
- Watt densities to 230 W/in2
(35.6 W/cm2) available on small
diameter nozzle bands
- Watt densities to 100 W/in2
(15.5 W/cm2) available on large
diameter barrel bands
- Operating temperatures to 1400F (760C) make it possible to
safely melt even the newest resins, like PEEk, Teflon®, Ultem®
and Zytel®.
- Higher watt densities than any other band contribute to faster
heat-up and through-put to increase productivity High thermal
Conductivity of MI and low mass construction give almost instant
response to temperature control This performance solution eliminates
thermal lag and temperature overshoot associated with ceramic
knuckle heaters.
- Stainless steel cover as well as side fold design resist
contamination by overflow of plastic or other free-flowing materials.
- Side folds turn to the inside diameter rather than the outside
diameter.
- Permanently attached clamp bars eliminate cumbersome
clamping straps, which makes installation easier.
