A Wire Annealing and Tinning Machine is a specialized piece of equipment used in the wire and cable industry for the annealing and tinning of wires. It combines the processes of wire annealing and wire tinning into a single machine, providing an efficient and streamlined solution for wire preparation.
The Wire Annealing process involves heating the wire to a specific temperature and then slowly cooling it to relieve internal stresses, improve its ductility, and enhance its mechanical properties. Annealing is particularly beneficial for wires that have undergone drawing or other mechanical processes, as it helps to restore their flexibility and reduce brittleness.
1. Description:
Application: Wire annealing and tinning machines are used for softening copper wire and applying a hot tin coating.
Wire Diameter Range: These machines are designed to handle a specific range of wire diameters, typically between 0.1mm and 0.4mm.
Equipment Picture: The search results did not provide a specific equipment picture, but you can refer to the manufacturer's website or contact them directly for more information.
Technical Parameters: The technical parameters of a specific wire annealing and tinning machine model include the inlet diameter, pay-off bobbin size, take-up bobbin size, maximum wire number, storage tank capacity, maximum speed, and heating method.
2. Production Process:
The production process of tinned copper wire using an annealing and tinning machine typically involves the following steps:
Pay-off: The copper wire is pulled from a pay-off bobbin, and its surface should be smooth and round.
Annealing: The copper wire is heated to a specific temperature to soften it, which improves its elongation properties.
Pickling: The wire is cleaned with a pickling solution to remove any impurities and ensure good adhesion between the tin layer and the copper wire.
Tinning: The wire is passed through a tin furnace, where it is coated with a layer of molten tin.
Cooling: The tinned wire is cooled using air or water cooling methods to solidify the tin coating.
Take-up: The tinned wire is wound onto a take-up bobbin at a controlled speed.
