Description

Technical Field

[0002] The processing process of spring wire is time-consuming and laborious. Generally, the straight wire is wound around a winding rod, and then placed in a baking oven for constant-temperature baking. After the plastic of the wire sheath layer recrystallizes, it is taken out and cooled. Finally, the spring wire needs to be rewound. The electrical sheath used for processing spring wire mostly adopts PU material, which is generally hard.
