Hiraguchi Seitan has successfully created a special lubricating film, free of pollution issues and capable of withstanding continuous handling. Their Dream Lubricating Film is constantly in use at Hiraguchi Seitan.

In the past, hydrochloric acid and sulfuric acid were used, which required special treatment. For each gram of zinc phosphate film produced, 1 gram of sludge resulted. The sludge became industrial waste.

Removing the sludge is also a problem for the assembly line. With the lubricating film Hiraguchi Seitan has developed, the oil is simply sprayed onto the film and it penetrates through fine holes that are provided. The film can be continuously handled on the manufacturing line.

Film development is complete for iron and aluminum, though efforts continue for other metals. Not only does this lubricating film simplify processes, it is beneficial to the environment because of the pollution it saves.

Hiraguchi Seitan has many technologies for working with stainless steel, and is particularly skilled at deep drawing and drawing odd-shaped objects.

The basic issue when trying to extend the formability limit of deep drawing is the relationship between the drawing resistance and the strength of the material. If the material strength overcomes the drawing resistance, a deeper draw can be carried out. Conventionally, the drawing ratio has been no greater than 2.35.

Using their lubricant, however, Hiraguchi Seitan has made it possible to double the drawing ratio.
