Description
In the plastics industry, the mica band heater provides a means of applying heat to any cylindrical machine part, mostly the barrel, end cap, or nozzle of plastic molding equipment. Mica band heater is conductive heaters providing thermal conductivity to the outside steel surface. The heat transfer from the mica band heater to the barrel plays a major role in determining the heater life as well as the efficiency of converting electrical energy into heat for the barrel.
Mica Band heater for Injection Mold is designed and constructed for long, efficient service. The construction design and materials used in custom mica band heater has demonstrated achievement of the necessary long service life for high productivity of plastic molding and extruding machines.
Mica band can be made into many combinations, and are constructed similarly to the Thinband – with the exception of the following:
Mica Bands are available in Strip Styles.
Mica band heaters support up to 900 degrees F. Call or e-mail our engineers to discuss your needs today. If we don't have your heater in stock, we have 1 day, 3 day, and 5 day rush available for quick shipping on custom designs. 10 days on manufactured standard lead-time.
Our heater best mica bands suppliers have local stock and factory stock of several designs of mica band heaters ready to ship!! If one of the stock units will not work for you, we can supply an assembly stock unit to cover your application needs in 1, 3, 5, or 10 days.
Designed For Trouble-Free Service
Our band heater disign is the result of many years research,development and testing for a reliable mica insulated band heater that can perform at higher operating temperatures(up to 480 ℃),essential to process high temperature resins,providing long,efficient service for today's high productivity of plastic extruders,injection and blow molding machines.
The solutions when the plastic injection machine band heater do not work.
1.Check the power is normal or not, if the power is off or the voltage is too low,the mica band heater will not work.
2.Check the band heater itself is damaged or not,or check the connection is normal or not,these factors will also influence the heating.
3.Promise the operation is right ,to check if the temperature setting of plastic inspection machine is right.
Promise the clearness of the band heater for plastic injection machine.

Installation and Operation
To maximize performance of the band heater, follow these instructions:
• Do not bend 1 piece heaters
• To provide close contact with heating surface, tighten clamping bands while taping aroundthe outside of band heaters. After heat-up, occasionally re-tighten the clamping band.• Match the wattage of band and strip heaters as closely as possible to avoid excessive on/offcycling.
• To tighten post terminals, bottom nut should be held in place while tightening top nut (toavoid putting stress on terminal).
• Avoid spilling oils, grease, water or molten plastic on leadwires, post terminals or ends ofheaters.
• Do not pull on leadwires with a force exceeding 15 lbs.
Application
Terminal Choice
Good efficiency
Good lifetime (mean time to failure)
Mica band heaters are great low cost heaters
Easily customized and quickly manufactured
They are easy to maintain and under proper care will last for years
PS&E mica-type band heaters have several advantages over other types of band heaters. What makes them the most used heater in the plastics industry is the combination of reasonable high-watt density capabilities, reasonably high temperature capabilities (900° F), their efficiency, lifetime expectancy and low cost.
