 How is soap made?

 Four Steps of Soap Bar Manufacturing:

  1. Batching
  1. Refining, homogenising and extrusion
  1. Cutting
  1. Pressing

Batching Stage

Each bar of soap starts at the batching stage. Our master Batch Makers are responsible for mixing ingredients according to each of our customers formulation specifications. Soap noodles are weighed according to a batch sheet and dispensed into a large mixer.  Colours, fragrances and special additives are added at this stage to the batch.

Refining and Extrusion Stage

All of our soap bars pass through a process of triple milled, also known as French milled. Triple Milling of the soap homogenises and compacts all of the ingredients into ribbons of soap that give the soap bar greater lather and longer life.  After milling the ribbons  pass through the first refiner which is pushed through a mesh screen to further refine the base of any impurities. The soap then passes through a vacuum chamber which extracts air out of the soap to ensure that it is free of air pockets or streaks. In the final extrusion stage, a nose cone heats the soap billet to make it more pliable and perfect for pressing. An extrusion plate dictates the billets shape as it is prepared for the next stage.

Cutting Stage

Soap billets are cut into a shape that will fit the selected die using a Savoncut servo driven cutter with a high degree of accuracy. Cut billets move along on a conveyor belt as they prepare for the pressing stage.

Pressing Stage

At this stage a Stampex press compresses two portions of a soap die together, resulting in excess soap being squeezed out through a parting line around the perimeter of the bar. The unique feature of the press is the double stamp action from the internal gears of the soap press giving greater detail to the embossed images and shape of the soap bar.  All Stampex pressed bars have parting lines, but they can be a high or mid-parting line, depending on the die used and the desired final result. Stampex presses are highly efficient as excess soap is recycled into the soap extruder and  easily reused to make more bars.
