A can manufacturer in Anhui province has successfully solved the problem of black lines and reduced the can breakage rate by 30% by using WOUFORM 48 stamping fluid and WOUFORM 47 can stretching fluid

A Chuzhou can manufacturing enterprise produces aluminum two-piece can bodies and uses a certain foreign brand of punching/stretching liquid. During production, it faces two main problems: firstly, frequent occurrence of black lines, which cannot be covered by light colored ink, resulting in low yield rate; Secondly, the tank breakage rate is relatively high, exceeding 50ppm. Ask Ou to recommend customers to try cup making solution WOUFORM 48/stretching solution WOUFORM 47, which helped customers completely solve the problem of black lines. At the same time, the tank breakage rate has decreased to below 40ppm, with a reduction of even more than 30%.

Challenge

A Chuzhou can manufacturing enterprise produces aluminum two-piece can bodies and uses a certain foreign brand of punching/stretching liquid. During production, it faces two main problems: firstly, frequent occurrence of black lines, which cannot be covered by light colored ink, resulting in low yield rate; Secondly, the tank breakage rate is relatively high, about 50ppm.

Solution

Wenou has gained a detailed understanding of the production process, mold ratio, coolant parameters, and flow rate of the enterprise, and has conducted performance tests on foreign brand products used by customers.

The analysis results suggest that the main reason for the above problems is that the lubricating performance of the cup filling fluid of competitors is weak, resulting in high friction heat release and black stripe problems; The dispersibility of the stretching coolant is weak, which can lead to unstable stretching process. In addition, the friction coefficient of the cup filling liquid is relatively high, resulting in a high breakage rate due to various factors.

WOUFORM 48 cup filling solution uses special polymer esters combined with unique extreme pressure additives, which can form a stable lubricating oil film in the processing deformation zone, reduce friction and heat release, and avoid scratches.

WOUFORM 47 stretching fluid is a fully synthetic product with excellent lubrication and cooling performance, particularly with excellent dispersion and settling properties, which can avoid the formation of agglomerates caused by viscous substances wrapping metal debris, resulting in unstable stretching process.

achievement

After using WOUFORM 48 stamping fluid and WOUFORM 47 can stretching fluid, the challenges faced by the customer were effectively resolved. The black stripe phenomenon has almost disappeared, the yield rate has significantly increased, and the can breakage rate has decreased from over 50ppm to less than 40ppm, or even below 30ppm.

Value created for customers

·Improved product yield and reduced can breakage rate by over 30%

·Improved production efficiency and reduced overall costs
