Cold wire drawing lines

Machines and wire equipments

General description

Cold wire drawing lines are used to produce cold drawn steel wire in spider reels or coils.

Cold wire drawing lines manufactured by Promostar are complete lines or just single unit able to reduce the diameter of the plain wire by means of multiple reduction steps up to the desired size on the final product, which has to complain to the market.

Drawn steel wire applications are normally for the industrial or agricultural sector for the production of smooth wire, galvanized wire, bright wire, barbed wire, bailing wire, barrier strand, fencings wire, spring wire, nails and tying wire.

Thanks to more than 40 years of experience in the field of process of rolling, we manufacture high performances automatic turn key plants, that are tailor made on the needs of our customers in terms of layout, products sizes, mechanical properties, level of automation and which allow to finally reduce the transformation costs for each tons of steel wire produced.

Our offer is not limited to the construction of machines and equipment. If required, we are also able to supply valid training, technical assistance and consulting to improve the production of the drawing process; These services are the keys to reach the target and maintain it over time in terms of efficiency and performance of the plant as well as in terms of correct mechanical properties of the wire produced.

Final products

Our cold wire drawing lines

The lines for COLD DRAWN WIRE COILS are the followings:

COLD WIRE DRAWING LINE MAIASTAR DV

COLD WIRE DRAWING LINE MAIASTAR DO

Both are multi-pass drawing machines that can do more than one reduction where the total number of the drafts (or reduction) depend on the final wire diameter to produce. The main difference between the two lines is the orientation of the axes on the capstans. In the model MAIASTAR DV they are oriented vertically while in the model MAIASTAR DO they are oriented horizontally.

The wire rod, pulled by the high-performances bullblock and controlled by latest technology PLC, is cold rolled by the die drawing boxes or by the rolling cassettes or by a combination of both (one device for each capstan blocks) that reduce the diameter to the desired size improving the mechanical properties and the roundness of the wire.

Depending on the packaging of the final product, at the exit, the machines can be equipped with static coiler deadblock machines that collect the wire on spider reels or with horizontal wire spoolers that collect the wire on fixed or collapsible spools.
