Audited Supplier Heat Bonding All bondcoats can be heat bonded, either by oven-heating or by directing hot air on to the wire during winding. In either case, the principle is to heat the winding slightly above the bondcoat's reflow temperature and then cool it below its rated bond strength temperature. Oven bonding is accomplished by heating the coil for a period of time sufficient to obtain uniform heating throughout the winding, followed by a cooling cycle. Heating time is generally 10 to 30 minutes, depending on the size of the winding.
Disadvantages of oven bonding are the longer bonding time as well as the potential need for many winding fixtures. Hot air bonding, though done typically at slower winding speed, has the advantage of the elimination of a secondary bonding operation. This method is cost effective and usually associated with low temperature bondcoats and wire sizes smaller than 34 AWG.
Feature:
Bondcoat uniformity: The distribution and uniformity of the magnet wire bond coat is more consistent and predictable compared to varnish coatings. Most products manufactured utilizing bondable magnet wire, possess greater bond consistency throughout, compared to varnished products. In addition, the finished unit is solidly bonded and may not require any external retaining device, forms, ties, or braces.
1)Imported high quality copper and environmental protection enamel are adopted in the series
of the products to improve tensile strength and uniformity of the film.
2)Stable impedance, uniform diameter, good electrical performance are always kept and
resistance to high-temperature, wear and corrosion have further promoted in order to
guarantee the wonderful effect of bonding and range, bright and clean surface.
3)It fits the harsh environment of special motors and meets the requirements of the times for
it has replaced the varnishing process and improved its environmental protection level.
