From the moment the huge blocks of raw material enter the factory until the moment the final product is packaged and prepared for shipment, our stones undergo several transformation processes until their ultimate shape is achieved.
The granite blocks extracted by Transgranitos, as well as the blocks acquired in other quarries, are stored in this park, thus constituting our raw material stock.
These blocks are later transformed into one of two production units: granite and marble and limestone.
According to the customer's needs, the blocks are selected and placed in a sawmill for transformation into sheets of different thicknesses.
Oversized blocks, often more than 180cm high, are sawn in just 7 to 8 hours.
We have a sawing capacity of 30,000m² of granite sawing and 7,500m² of marble or limestone per month.
The slabs at this stage can be sold to intermediate product customers, in this case the distribution warehouses.
For transport by truck, they are loaded on iron trestles.
Traveling by boat, in a container, they are loaded on wooden slats.
The slabs are also used for the elaboration of finished work. For this, they are moved to the easel next to the cutting centers.
Robotic dollies load the slab to the cutting machines where they are photographed. The cutting operator consults the parts to be cut in the control panel library and makes the most profitable composition, taking into account possible defects that the sheet presents.
Then, the machine, which works autonomously and by numerical control, makes the cut according to the programmed, whether straight lines, curves, perpendicular or inclined cuts.
At the exit of the machines, the parts are removed with the support of vacuum manipulators and referenced in a permanent ink printer.
For curved parts where the radius of curvature is quite small, we use waterjet cutting.
With an accuracy of tenths of a millimeter we can make any figure on any type of stone.
After being cut and depending on their use, the pieces may need some supplementary finishing, in order to guarantee the effective fulfillment of their function:
For works with special, bulky and three-dimensional pieces, we use machines that cut with diamond wire with several axes of freedom and CNC milling machines that allow, in an autonomous and automatic way, to make any type of shape in the stone.
They are widely used to perform:
In addition to gluing and mechanically fixing parts to each other, there are highly detailed final finishes that can only be carried out manually with the help of small equipment and tools.
For that, we have an area dedicated only to these works, where a team of highly specialized collaborators is present, who we consider authentic sculptors.
In special cases where the customer requires it, it is necessary to place the pieces on a floor of our facilities, in the position where they will later be applied on site.
It serves for verification and validation by the client and for internal control of the performed work.
After rigorous quality control of all parts, they are packed in pallets or wooden boxes with protection that allows safe handling and transport to the customers' premises.
The entire packaging process is carried out at Transgranitos facilities.
We provide all kinds of solutions for civil construction and decorative pieces. We develop tailor-made solutions.
