Frequently Asked Questions

After the deep drawing process, will the wall thickness become thinner?

In deep drawing processes, such as forming a cup shape from a single metal sheet, the wall thickness of the tubular section can be adjusted to be slightly thicker, the same, or thinner. To ensure high product accuracy, it is essential to match the thickness of the steel sheet with that of the tubular section. For instance, it is possible to reduce the thickness 0.6mm sheet to 0.3mm thickness in the tubular section.

What is the difference between deep drawing processed pipes and normal pipes?

With deep drawing technology, we can produce relatively uniform wall thickness around the circumference, with less variation. Due to the work hardening effect, deep-drawn pipes are often harder and more rigid compared to standard SUS304 pipes. We produce various kind of cylinders, pipe-shaped products.

Regarding surface roughness, since it also affects sliding surfaces,
I would like to request that the specified value be based on the data from the machining process.

A.Controlling surface roughness is generally challenging in deep drawing processes. Additionally, the surface characteristics differ between machining and deep drawing (plastic deformation).

Therefore, rather than relying solely on numerical values, it would be better to conduct actual tests to make a proper assessment.
