Innovation, Precision and Commitment to Excellence
[Our Technology]
We are supported not only by decades of experience, but also by an infrastructure equipped with state-of-the-art resources, and the obtaining of quality certifications that validate each of our actions.

At Bunker Composites, we see technology as the core of our productive development. The incorporation of cutting-edge processes, the interdisciplinary work of specialized engineers and technicians, and a rigorous control system allow us to meet the highest standards in the international market.

Production process

From the idea to the final product

At Bunker Composites, we carry out a fully integrated production process, adaptable to the requirements of each customer. From the initial design to the delivery of the finished product, we apply carefully designed procedures, which are developed in a 2100 m² plant equipped with the latest generation of technology.

[1]
Initial work
Our technical team works on our own designs or those provided by the client, using software such as AutoCAD, Rhinoceros and CATIA. Through 3D models (renders), precise visual proposals are presented that allow us to validate the geometry, the demoulding angles and the technical requirements of each piece.
[2]
Modeling and prototyping
With the approved design, a physical model is manufactured on a real scale (1:1) in our 3D Machining Center, using CAD-CAM technology. This instance allows you to obtain an exact and functional replica, ready for the development of matrices and molds.

Matrix manufacturing and lamination
Once the model is generated, the production matrix is drawn up. Depending on the type of piece, we apply laminating techniques such as:
‍
- Hand Lay-up
- RTM (Resin Transfer Molding)
- RTM LightSpray-up
- TRV (Vacuum Resin Transfer)

Our installed capacity allows us to produce up to 10 tons per month in fiberglass reinforced plastic (GRP) parts, with processes that can be adapted to the volumes and specifications of each customer.

Machining and finishing
Subsequently, the parts enter a closed sanding and burring sector, where they are machined with precision tools until they strictly comply with the technical drawings. Manual finishing tasks are then carried out and, if necessary, plastic putty is applied to ensure a perfect finish.

Painting and treatment
We have a specialized area of 700 m² dedicated exclusively to painting and curing the pieces, equipped with:

- Ink preparation room
- Thermally controlled spray booth
- Drying room and flash-off
- Curing stove with circulating air

We work with two-component polyurethane paint (2K), ensuring high resistance and a uniform finish.

Assembly, final inspection and improvement
At this stage, the parts are assembled and accessories are incorporated into them according to technical specifications. They then undergo a rigorous final quality control, after which they are packaged or placed in specific delivery devices for shipment.

Every step of the production is recorded. The detected problems are analyzed and documented, making it possible to update the process sheets and permanently optimize each procedure. This approach allows us to consolidate a robust technical track record, which translates into efficiency and predictability.

ISO 9001 Certification

Internationally Certified Quality Management System
[Technology at the service of results]
Each of our processes is designed to deliver quality, repeatability and performance, applying the best industrial practices to high-performance parts.

The ISO 9001 Certification, granted by TÜV Rheinland, one of the most recognized entities in the world, represents an institutional milestone for Bunker composites. This achievement is the result of the constant effort and commitment of all the members of our organization.
