I want to eliminate stains caused by seepage from the tapped holes and seams of the zinc plating.
We will introduce a case that was solved using know-how for cleaning the bonding surfaces and preventing seepage from tapped holes.
We would like to introduce a case of a customer who is struggling with seepage from spot welds, bonded surfaces, and screw holes. San Kogyo's zinc plating line consists of two types: an automatic plating line suitable for mass production and a manual line where skilled workers perform plating by hand for each individual item. In the manual line, we have the know-how to clean bonded surfaces and prevent seepage from tapped holes, which allowed us to eliminate the seepage stains that the customer was facing. 【Issues】 ■ The processed iron products are experiencing appearance defects due to seepage from screw holes, causing problems. ■ Although we have requested that screws be inserted in advance to make it difficult for liquid to enter the screw holes, seepage still occurs, resulting in contamination. ■ Liquid also seeps out from the bonded surfaces after plating, leading to stains. ● For more details, please visit our company website and contact us.
