c2i has a MAKA 5-axis milling machine of 6 x 3 x 1.5 m and can make models of up to 22 m long by turning the parts. We produce patterns/models or tools directly into tooling block material. We also trim carbon-fibre or glass-fibre components for external companies and can design and make the trimming jig in-house. We also have a new 3-axis 1.5 x 0.8 x 0.7 m CNC machine for metal tooling.

c2i can accept 3D models of different formats such as IGES or STEP and then program the milling path using CATIA V5 CAD/CAM software. This program is automatically transferred to our 5 axis milling machine. This process allows us to build patterns and/or tools of about 0.1 mm accuracy per meter and is suitable for aerospace, automotive, marine, rail, sports, medical, architectural, product design and other industries.

c2i also has experience in the production of tooling using more traditional methods. Here, c2i receives 2D component drawings and produces the pattern using wood, pastes and fillers and polishes to high quality surface finish. Despite the lack of dimensional accuracy of this method compared to the 5 axis milling approach, the lack of 3D computer models or the need for large, simple shaped tools without tight dimensional tolerances can make the traditional approach more cost-effective.

Once the pattern is produced we produce moulds using wet lay-up, resin infusion or prepreg, however, until planned investment into autoclaves only out of autoclave prepregs.
