PRESSES – STAMPERS  mod USN

An absolutely unique soap stamping concept. Definitively the most important innovation in soap machines of this decade. Once again the innovative spirit of Binacchi & co has led to a milestone patent:  the de-flashing plate is incorporated into the lower die and generates compacted scraps that are easily recycled in the plodder. In addition the lower die is stationary i.e. does not rotate or move at all). 

The advantages of this solution are countless. Just to mention the most important ones. Dies change-over is easier and faster

Rotating joints for coolant are eliminated and much more refrigeration can be applied.

Higher soap quality due to higher stamping pressures and thin partition line.

The faster models of USN are based on ultimate Binacchi Mechatronic Design: all machine timings are no longer obtained by inflexible mechanical cams but utilizing servomotors and "motion" software. This permits to always find the optimal settings for your soap and your operating conditions guaranteeing you high working efficiency and maximum soap quality. Cam boxes or other delicate mechanical equipment are no longer used with consequent easier machine maintenance.

The USN presses also benefit of VVD variable Volume Dies: It is a unique patented system allowing to adjust the stamped soap bar weight, typical problem caused by product density variation. The VVD allows to adjust the position of the bottom section, simply by turning a hand wheel. In this way the volume can be changed ± 2 grams approx. Saving 2g per bar in a line producing 300 bpm – 24 h/day means 160 ton/year of “giveaway” soap will be avoided with a saving in the area of 150.000 Euro / year.

In case of banded soap, moreover, the system is even capable to produce soaps with different weights without changing the die set, simply by modifying the height of bands.

The Binacchi USN presses are designed to stamp all shapes of banded and bandless soap with a “flash stamping” system but upon request Binacchi can supply Die Box mechanism with no overflashings production, utilized for big laundry soaps and to press casted transparent soaps (see photo). 

Various models are available for capacities up to 800-1000 bars/min.

STAMPING CYCLE DESCRIPTION

It consists of one lower fixed half-die over which a soap billet (slug) is deposited by vacuum cups. The other half-die comes down to press soap bars. Soap overflashings are compacted inside the special patented profiles, shaped in the inferior dies, and fall down onto the recycle conveyor in a very compact form, avoiding the typical problems of soap recycle. The half-die raises leaving stamped bars in the bottom half-die from where they are removed by a set of vacuum cups.
