    Our Well-Thought-Through Work Process

    An overview of TY Metal processing line:
    •Once the wire rod delivered to our facility, it's bathed into a coating tank and then baked in preparation for the drawing process
    • When the coated wire rod dried, it'd be put through a series of multi-die wire drawing machines to reduce the diameter till desired
    • The wire can also be annealed to soften it by fed through a furnace where it is heated then quenched in water
    • It may then be drawn again to the exact diameter required by the customer

    Final Processing

    Cold Drawing

    The cold drawing machines have small-diameter dies. They cold-draw wires into close tolerances and improve surface finishes.

    Annealing

    After cold drawing, the annealing heat treatment is needed to restore the material properties. This is done with a continuous annealing and quenching line.

    Pickling

    With acid treatmen, pickling removes high temperature scale produced in heat treatment or hot working. It also removes rust from corrosion or contaminant iron of the steel.

    Skin-passing

    Skin pass forms the wire into appropriate mechanical properties. It is a very light cold-drawing treatment that applies the least amount of reduction. The purposes of skin passing are:

    • Remove surface blemishes
    • Improve the wire shape
    • Achieve the desired mechanical properties

    Final Processing

    The final operations are where wires tailored to customer requirements, including:

    • Coil the wire to the standard or desired weight
    • Apply a clear plastic film to provide protection for further processing by the customer
    • Apply other kinds of surface protection of the coils
    • Special packaging procedure for specific requirements

    Cold Drawing Line

    Wire Drawing Is An Significant Step In Manufacturing Processed Wires.

    Wire drawing is often referred to cold drawing, it is a process of reducing the cross section of a wire by pulling through a die or series of dies. Because of the increasing demands of wire properties, demands of wire drawing machines are also on the rise.

    Annealing Line

    TY Metal's Furnaces Process Wires In High Speed. Annealed To Achieve Optimum Results

    TY Metal's annealing line includes three furnaces, they are state-of-the-art and process wires in high speed. These continuous wire annealing furnaces are essential in our production workflow, they eliminate the lubricants on the wire and anneal the stainless steel wire to certain tensile strength.

    The temperature and power of our furnaces can be completely controlled. To reduce atmosphere, the furnaces are equipped with gas manifolds to allow respective control of each process. TY Metal's furnaces are also furnished with water-cooling tanks to facilitate temperature control and they require minimal maintenance.

    Below is a glance of our continuous wire annealing furnaces.

    Zoned For The Best Performance

    Our wire annealing furnace is heated in multiple zones to fast heat-transfer to the wires and perform consistant temperature. The fume extraction system and covers are set up to increase safety and reduce environmental impact. Each of our continuous annealing furnace includes 3 parts:

    • the combustion chamber, heated by 1 to 3 burners
    • the waste gases that are guided into the entrance of furnace
    • against the heat current, wires going through the furnace

    Because our furnaces are equipped with a wide range control of temperature and speeds, we can obtain different wire tensile strengths. Wires that do not have to be annealed can also be passed through the foundations of the furnace. Wires we processed can go down to 0.8mm diameter with various tensile strengths acheived.

    Efficiently Operated Furnaces

    In order to obtain the best annealed wires with consistent and precise tensile strength, TY Metal is established with the state-of-the-art furnaces. Features of our bright annealing furnaces are:

    • High wire speeds
    • Low operation cost and low consumption
    • State-of-the-art combustion & control 
    • Solidly built for long-standing production
    • Channels are individually adjustable
    • Easy operation — combustion chamber heated by only 1 to 3 burners
    • Approx. 40 to 90kg/mm² tensile strengths can be achieved
    • The entire heating cover can be lifted for combustion chamber maintenance

    Precision Wire Drawing

    We Are Capable Of Drawing Wire Down To Diameters Between 0.8mm And 25mm

    The minimum diameter of wire rod supplied to TY Metal is 5.5mm, and we are capable of drawing wire down to diameters between 0.8mm and 25mm.

    Exceptional wire drawing capbilities and knowledge

    Our production facilities and technical staff have exceptional wire drawing capbilities and knowledge from product specifications to flexible packaging.  With decades of experience of manufacturing wire products, TY Metal has established a holistic knowledge of wire processing and material specifications.

    The quality of the product is determined by the wire drawing production process

    Different grades of steel can be formed into various properties with different processing. The production process affects the quality of the wires and application products.

    Attentively care for each step

    We draw down wire rods until final product meets the buyer's requests for diameter, mechanical properties and surface finish. We attentively care for each step during the production.

    Stages of Our Wire Drawing Process

    Cleaning

    Remove abrasive scale on the surface of raw wire rods.

    Coating

    Apply drawing lubricant onto the surface of the wire to aid cold drawing.

    Pointing

    Because the dies are always smaller than the section of wire, we sharpen the wire ends so it can pass through the drawing dies smoothly.

    Drawing

    The pointed end of the wire passes through the dies and enters a gripping device of the drawing machine. The drawing machine pulls the remaining of the wire to go through the dies. The wire's cross section is reduced and its profile shaped.

    Finished Wire

    The drawn products appeared a bright finish, with desired mechanical properties.

    Multi-Pass Drawing

    To produce the desired shape and tolerances for complex wire profiles, coils may need to be drawn several times. This process let wires draw through smaller and smaller die openings. To increase ductility and remove cold work, wires are usually annealed between each drawing pass.
