Pieces

The pieces of molded pulp are generated, as its name implies, molded fiber paper and cardboard; that they are suspended in an aqueous emulsion ...

The molds are dipped in the emulsion and by removing them with vacuum the solid fibers are deposited on the surface, copying the mold shape. Then the pieces are transfered from the mold and dried with an oven. From the moulding process, the pieces have the characteristic of being mainly laminar and understood conceptually as shells. The pieces need to unnest from the mould; meaning it must respect minimum angles for removal.

The volume is generated by working with the surface, therefore, the strength of the parts is increased with its thickness. This is an intricate surface, having greater resistance than a flat surface. The pieces may have different thicknesses, ranging from 0.8mm to 10 or 15mm.

Molds

Molds or tooling are relative and proportionately more affortable than EPS molds. They can be made of aluminum, bronze, brass or plastic, depending on the quantities ...

they are needed and the life expectancy required. They are made from laminated bloque machining or cast solid. It consist mainly on two parts: a forming mold where the fibers are placer and another mold part which extracts the molded part and places it in the drying oven are deposited. The manufacturing time of the molds varies according to the size and complexity of the part, but it is estimated in the order of 30 to 45 days.

Machines

Our manufacturing technology was designed exclusively to meet the diverse requirements of our customers. Because of its unique design, it allows us to produce ...

a wide variety of shaped pieces, sizes and volumes of relatively from low to high production scales, in comparison with other manufacturers. We are capases to process up to 450kg of material per hour, allowing us to comply with production to the demand of our customers.
