[Explanatory Material] What is Barling? (Video Included)

Improved cleanliness and strength!? Here's a summary of the two-birds-with-one-stone processing method 'burring' used for stainless steel containers.

"Burring" refers to a processing technique where a hole is made in a material and the edges of that hole are extended in a cylindrical shape. This technology is generally used to secure screw threads, but at Nitto Metal Industry, it is employed for purposes such as improving the cleanability of containers. In industries such as pharmaceuticals and food, where preventing foreign matter contamination is particularly emphasized, stainless steel containers are often used due to their resistance to rust and hygienic properties. The "cleanability," characterized by the difficulty of dirt accumulation and ease of cleaning, is an important point in equipment selection. The processing technique that demonstrates effectiveness in this regard is the "burring process" that we will introduce here. This document will outline the methods and purposes of burring processing at our company.
