Graphenglass has a large, specialized workforce in composite materials manufacturing, with hands-on experience in transformation, molding, finishing, assembly and production control processes.
The knowledge accumulated on the shop floor and our command of different manufacturing technologies allow us to take on demanding products and series with solidity, repeatability and industrial judgment.
Experience built by manufacturing.

Research with an industrial objective
Graphenglass was founded in Castellón in 2017 with an idea that still defines the way we work, solving technological challenges with series manufacturing in mind from the very start.
Our first years focused on developing technologies for graphene applications, researching how to integrate the material into polymer and mineral matrices in order to carry its properties into real industrial solutions. That work produced proprietary technology protected by US patent 11,807,761 B2, and laid the basis for a very specific understanding of innovation, always oriented toward an industrial objective from the very first moment.
From graphene applications to materials challenges
Over time that experience evolved into a broader field. Today Graphenglass works on solving complex challenges in composite materials, product development and manufacturing processes, particularly where existing solutions are not enough. We start from the requirements of each application and develop the material, the process and the means needed to make it real, all together.
We do not stop at the laboratory or the prototype
What sets us apart is that we do not stop at the laboratory or the prototype. We design taking into account from the outset how a part will be produced, how the process will be controlled, what it will cost and how it can be repeated with quality. This has allowed us to turn our own developments into production processes, components and solutions that can be manufactured in series for demanding industrial applications.
A long tradition in materials, chemistry and industry
Graphenglass is a company deeply tied to Castellón, a region with a long tradition in materials, chemistry and industry. That environment is part of our culture, combining experimentation and engineering with a practical view of the plant, production and the market.
Headquarters at Av. de Valencia, 197, Castellón de la Plana.
Technology and business advance together
The company was founded by Vicente Montesinos and Javier Heredia, whose complementary careers have shaped its development. Vicente brings broad business experience linked to the industry of Castellón, to national technology entrepreneurship and to launching new global ventures. Javier brings a career centered on engineering, materials, product development and industrialization. That combination produces a company in which technology and business always advance together.
At Graphenglass we are drawn above all to problems that do not yet have an obvious solution. We develop new materials, adapt technologies, design processes and create the means needed to manufacture what did not exist before.
