(chapter I)

This article talks about the history of a very important stamper in the soap field: six faces soap stamper. The next article will talk about how Soaptec has improved the design and productivity of this kind of stampers

Stamper HEXA

The characteristic Marsiglia soap cubic shape is one of the ancient and traditional soap shapes still in the market. As was used to do once, all faces (or at least four) are usually engraved, together with the logo and the producers name, with the TFM content as a quality sign.

As well as still being present in European markets, where has become symbol of purity and quality, cubic soap is also the predominant soap shape in such African countries.

Hexa 5.0 is nowadays the most developed machine that produces this type of soaps.


Traditionally the market used to offer two different types of machines for named “six faces soap” or “cubic soap” production: both projects were as old as the product was.

First machine was also called “artichoke” and it used to close the mould with some cams. This concept required an incredible sturdiness, as time went by production costs became incompatible with production gains and with new technologies requirements.

Second machine, used to close the stamp with a ring that get levis closer to its perimeter. This system was more favourable and offered, from a conceptual point of view, some advantages in terms of force-saving. Although the improvement, soap charge and discharge from and to the stamp were made by soap/soap contact: piece of soap ready for stamping pushed the already-stamped-soap out of the machine, so the quality of the final product was affected.

Furthermore, machines movements required huge openings on both sides of the machine so it was possible to see the movement of its internal components . Soap got into the machine and used to cause oil condensation so they were several maintenance and lubrication problems too.

Although this defects, considering the better price compared with competitors machines and thanks to a relative planning “simplicity”, the machine became the principal mean of six faced soap production. The producer of this machine tried to improve it without any appreciable result.

As time went by other laundry soaps and other means of production were developed: two faces stampers, cutters with engraving rolls… the six faces stamper was slow, relatively expensive, not user-friendly and difficult to maintain, and it used to produce a relatively bad-made soap, which caused an important decrease in the production and in the sales of Marsiglia soap.

Soaptec's HEXA

The HEXA was projected in this context, at the beginning of 2000 and following Soaptec philosophy: reliability, flexibility, few maintenance and ergonomics. Soaptec goal was to design a machine capable to produce up to 60 soaps/min and to produce an excellent quality soap. We made it.

In the next article we will explain how does HEXA works and which are its particularities.
