We have been making for over 60 years
Curved plywood

From the forest to the curved plywood –

Curved plywood manufacturing process

The raw material wood, comes from woods where the cut comes from registered and is always traceable, from cutting in the woods to our factory, moreover more than half of the trunks come from FSC® certified forests.
The production process starts from the trunk. The prerogative of browsing from, to 3C, one more chance for the supply of dimensionally and structurally non-standard elements.
The veneers can have thicknesses and dimensions calibrated on the experimentation of innovative stratifications.
Beech is our mother wood, but we also rob ash-maple-birch-poplar, this and more as needed.

PHASE 1 - LOG STORAGE

The logs are stored and marked on the log yard

^

PHASE 2 - evaporation tanks

The logs are placed in evaporation tanks for a few hours and then debarked and cut to size.

^

PHASE 3 - BROWSE

The dough sheeter produces 5/6 cubic meters of dough per day in different sizes and thicknesses

^

PHASE 4 - evaporation tanks

The automatic cutter obtains the necessary measurements and the material is labeled on the pallet.

^

PHASE 5 - Drying

The raw veneer is introduced automatically into the dryer, at the exit the material reaches the reference humidity degree.

^

PHASE 6 - Magazine browsed

The browsed warehouse is always monitored and a register of inputs and outputs is kept.

^

PHASE 7 - Preparation of the browsed

The veneer is carefully selected by qualified personnel with years of experience, to keep the quality of the final product high.

^

PHASE 8 - spreading

During the gluing phase, the veneer passes through the spreading machines. We only use adhesives with a low formaldehyde content.

^

STEP 9 - stamping

The wet and dry sheets make up the bundle which is introduced into the mould. The molds can be heated with oil or radiofrequency. In our mold warehouse there is a bit of history of the furnishing accessory, ca. 1000 molds are catalogued.

^

STEP 10 - contouring

4 numerically controlled machines with 3-4 and 5 controlled axes and pendulum machining allow us to quickly manage orders. A CAD/CAM programmer prepares the machines at each start of processing.

^

PHASE 11 - testing

The final phase of testing and finishing of the single piece makes use of brushing and sanding machines, however, the manual management of the piece by the operator remains essential.

PHASE 12 - finished product

The finished product is prepared for transport and delivered as needed

How the curved plywood of 3C Colabianchi Srl is produced.

The production process for curved beech plywood begins with the selection of wood from controlled and FSC-certified supply chains , which guarantee sustainable forest management. Once the logs are selected, they are stored and then subjected to evaporation and debarking to remove bark and excess moisture. At this point, the log is peeled to obtain a series of thin sheets, which are cut to size.

The beech plywood sheets are then dried to further reduce moisture content, ensuring greater dimensional stability of the finished product. Once dried, the plywood sheets are glued together using low-formaldehyde glues, ensuring environmental and worker health safety. The next step involves molding the plywood sheets, which are curved using special hot presses to achieve the shape required by the project.

After moulding, the plywood undergoes a contouring phase, where the edges are finished and made more regular. Finally, the product undergoes rigorous testing, which guarantees its quality and resistance. Bent beech plywood is used in many sectors, such as in the furniture and design industries, where its resistance and flexibility characteristics make it a precious and versatile material.
