Copper cable manufacturer improves copper wire surface cleanliness and reduces drawing fluid loss by over 20% through WOUCOOL 833Cu

A copper cable manufacturer located in Yangzhou is facing two main problems when using a competitor's drawing solution product: 1. There is a large residue on the surface of the copper wire, which affects the stranded wire and causes color difference in the surface quality after annealing; 2. After using the working fluid for a period of time, there will be a large amount of floating objects on the surface of the tank, resulting in a high consumption of drawing fluid. After consulting with Wenou Company, they switched to Wenou Copper Drawing Cooling Liquid WOUCOOL 833Cu, which significantly improved the surface cleanliness of the copper wire. In addition, WOUCOOL 833Cu has excellent copper soap dispersibility, greatly reducing the surface floating of the working fluid, making the performance of the working fluid more stable, and reducing the amount of drawing fluid by more than 20%.

Challenge

A copper cable manufacturer located in Yangzhou is facing two main problems when using a competitor's drawing solution product: 1. There is a large residue on the surface of the copper wire, which affects the stranded wire and causes color difference in the surface quality after annealing; 2. After using the working fluid for a period of time, there will be a large amount of floating objects on the surface of the tank, resulting in a high consumption of drawing fluid.

Solution

To address these challenges, the manufacturer contacted the European company. Wenou conducted in-depth investigations and research on manufacturers' equipment, water quality, and competitors' products. The analysis suggests that the main reason for the above problems is the poor dispersibility of the copper soap used by the customer in the drawing solution, resulting in a large amount of copper soap aggregation and causing a large amount of floating objects on the surface of the tank solution, which also affects the cleanliness of the copper wire surface.

Wenou recommends the use of WOUCOOL 833Cu to customers. This product is an emulsion coolant used for copper drawing production, with excellent lubrication performance and strong copper soap/copper powder dispersion and settling performance. It has the advantages of long service life and low comprehensive use cost.

achievement

After using WOUCOOL 833Cu, the challenges faced by the manufacturer were effectively resolved. The surface cleanliness of copper wire has been significantly improved, and at the same time, the problems of stranded wire in the subsequent process and color difference of copper wire after annealing have also been significantly improved, which has increased the yield of the product.

The total amount of floating debris on the surface of the tank solution has been significantly reduced, and the amount of wire drawing solution added has decreased by more than 20%. The customer is very satisfied with the performance of WOUCOOL 833Cu. Therefore, they look forward to maintaining a lasting partnership with Wenou.
