A shaped heating tube is a heating device made of high-temperature resistant stainless steel or quartz as the base material, filled internally with resistance wire and crystalline magnesium oxide powder, which transfers heat through the resistance wire's electrified heating. Its core features include:

Structure and Materials
?Metal Material?: Typically made of 304 stainless steel or 316L stainless steel, with an embedded spiral resistance wire and an outer layer filled with crystalline magnesium oxide powder for good thermal conductivity, supporting dry heating conditions. ?
?Quartz Material?: Made of quartz tubes with an integrated resistance heating element, featuring efficient infrared radiation characteristics, capable of directly heating target objects in a vacuum environment. ?
Performance Characteristics
?High Efficiency and Energy Saving?: Metal materials offer high thermal efficiency, while quartz materials achieve an electrical conversion rate of up to 80%, with fast startup (reaching full power within 5 seconds). ?
Durability?: Average lifespan exceeds 5,000 hours, supporting high temperatures (up to 900°C) and rapid cooling. ?
Flexible Application?: Supports custom non-standard structures such as Z-type, W-type, and spiral shapes, suitable for liquid heating, mold temperature control, plastic processing, and other fields. ?
Main Applications
?Industrial Heating?: Used for heating oils, water, chemical media, as well as temperature control in hot press molds. ?
Special Processing?: Suitable for equipment such as coating drying tunnels, PET bottle blowing machines, and photovoltaic sintering furnaces.
