Considering the cold and dry working environment in most Russian industrial workshops, we optimized the internal structure of this batch of cartridge heaters. The heating core adopts anti-aging nickel-chromium wire, and the lead wire connection uses enhanced sealing technology to prevent dust and cold air from affecting heating stability. Different from standard models, this order contains 8 different customized lengths to fit multi-station packaging equipment of the client. At present, over 60% of the production process is completed, including raw material cutting, wire winding, tube shrinking and high-temperature annealing. Our workshop arranges special personnel to classify and mark different specifications to avoid mixing errors. Semi-finished products are sampled every day to test resistance value and heating performance. After full production, all heaters will pass aging test and be packed with cold-resistant packaging materials, adapting to long-distance transportation and local low-temperature use in Russia.
