Equipment Overview
The Ultrasonic Degreasing Machine for Resistance Wire and Pipes is specifically engineered to remove tenacious oils, drawing compounds, and oxide films from resistance wires and metal pipes prior to powder filling and tube shrinking operations. Resistance wires and pipes used in heating element manufacturing are typically coated with lubricants from drawing processes and may develop surface oxides during storage. These contaminants, if not completely removed, can compromise MgO powder adhesion, create hot spots, and lead to premature failure of finished heating elements. This equipment uses high-frequency ultrasonic waves (28-80 kHz) to generate cavitation bubbles that implode against wire and pipe surfaces, breaking the bond between contaminants and metal without mechanical abrasion or chemical damage.
● Wire and pipe compatibility: Processes resistance wires ranging from 0.1mm to 10mm diameter and metal pipes up to 50mm diameter and 6 meters in length.
● Adjustable ultrasonic frequency: Multiple frequency settings (28kHz, 40kHz, 80kHz) accommodate different material sensitivities and contamination levels.
● Heated degreasing bath: Solution temperature can be controlled up to 80°C to enhance oil emulsification and accelerate contaminant removal.
● Programmable cycle control: Operators can set degreasing duration, temperature, and ultrasonic power according to specific wire and pipe specifications.
This equipment is suitable for degreasing resistance wires and pipes that require high cleanliness standards prior to MgO powder filling, tube shrinking, and final assembly into heating elements and cable systems.
Common Contamination Issues
Resistance wires and metal pipes used in heating element manufacturing are exposed to various contaminants during production and storage. These contaminants, if not properly removed, can lead to product defects, reduced service life, and safety hazards. The Ultrasonic Degreasing Machine for Resistance Wire and Pipes addresses each of these contamination types effectively.
● Drawing oils and lubricants: Residues from wire drawing and tube forming processes that can interfere with MgO powder adhesion, causing uneven heat distribution and hot spots in finished heating elements.
● Oxide layers and scale: Formed during heat treatment, annealing, or extended storage, these oxide films can reduce the bond between resistance wire and MgO powder, compromising insulation performance.
● Rust-preventive coatings: Temporary protective films applied during storage that must be completely removed before powder filling to ensure proper MgO powder adhesion and tube shrinking quality.
● Handling contaminants: Oils and salts transferred from operator handling that can cause localized contamination or corrosion of sensitive heating element surfaces.
● Particulate debris: Microscopic metal fragments and dust from cutting and handling operations that can create electrical shorts or insulation defects in assembled heating elements.
By effectively removing these contaminants, Feihong's ultrasonic degreasing machine ensures that resistance wires and pipes meet the cleanliness standards required for reliable heating element production.
