Cartridge Heater for High Temperatures TYPE A (21A3)
A cartridge heater made by the US company RAMA.High-temperature cartridge heater widely used for heating molds.For use at high temperatures, Incoloy is used for the sheath material, an Incoloy end disc is welded to the cartridge heater terminal, and a LavaSeal (special lava seal) is provided on the opening. It has been manufactured in a strictly controlled production process.Continuous sheath surface temperatures of up to 871°C can be maintained in addition to accurate and uniform heating at medium and low temperatures.A wide range of heater diameters are available, from φ6.25 to φ18.95. 332 types are consistently in stock.Customized items of different sizes and shapes can be manufactured within a short delivery time.UL standard products are also available with short delivery times.
[Notes]
· Max. Operating Temperature: 871°C (Heater Surface Temperature)
· Lead wire heat resistance temperature is 200°C.
· The vicinity of the lead wire exit port should be kept at or below 130°C.
· We recommend drilling holes to align the actual product, because malfunctioning heat exchange leading to abnormal heat generation that will shorten operation life occurs when the clearance between the mold hole inner diameter and heater outer diameter increases on heaters with a power density of 20 W/cm² or more.
· Note that the insulating tube easily comes off.
· Do not use the heater while empty in open air. There is a risk of breaking or catching fire due to abnormal heat generation if used with all or part of the heater protruding from the object being heated.
