In the production line, all the steps are carefully analized, so that way the final product will have a better quality.
Tests of quality are realized in each level.

The raw material is placed in rust-proofing tanks and is then mechanically put into packaging containers.
After further careful inspection these containers are than sealed using the most modern technology. Following this, new samples are taken for additional testing.

The validity date and the series number are printed on each container, as well as on the cardboard packing box, giving the customer all possible information about the product. For ease of re-ordering, the factory maintains all information about each series in its electronic database. In addition, test results are kept on file in our "Testing Samples" room.
By producing products for internationally respected companies such as WURTH, 3M, AC, DELCO, LOCTITE and WD-40, WINNER is active in many countries through the continuing recognition of our products.
