Dream Lubricating Film is a film with characteristics that make possible continuous handling without any pollution problems. At present, this film is undergoing continuous operation at Hiraguchi Seitan.

Conventionally, the production of this kind of film requires wastewater treatment because the process involves the use of hydrochloric acid and sulfuric acid. Also, 1g of sludge is generated in the conventional production of each 1g of zinc phosphate film, and this must be treated as industrial waste.

In addition, such films are difficult to make "in-line". But in the case of our newly developed lubricating film, simply spaying on oil allows it to permeate into even small gaps, a feature that makes possible continuous handling in manufacturing processes too.

At present, we have completed the development of lubricating films for iron and aluminum, and we are currently developing such films for other metals. Besides significantly simplifying the process of lubricating film production, as a non-polluting method our process also brings significant social and environmental benefits.

We possess versatile technology for stainless steel processing, and we are particularly good at deep drawing and irregularly-shaped product drawing.The basic problem that needs to be solved in order to loosen the forming constraints in deep drawing is the relationship between drawing resistance and material strength. If the material strength is greater than the drawing resistance at the time of processing, even deeper drawing becomes possible. Up to now, it has been possible to raise the drawing ratio to 2.35.

However, Hiraguchi Seitan has made it possible to double the conventional drawing ratio by using an in-house developed lubrication aid.
