C-Tech is a premium composites manufacturer in Auckland, New Zealand. The experience and expertise we have gained from our successful yacht racing background has supported us to become a preferred supplier to America’s Cup teams, the demanding Superyacht industry, Olympic sailors and Volvo Ocean Race campaigns.

From this, we have developed our composites skills to engineer world winning products beyond the marine industry, expanding into automotive, aerospace and the experimental aviation game changers.


Clean Room

C-Tech has a world class 600sqm high stud positive pressure, humidity and temperature controlled clean room. This infrastructure for our Pre-preg work has increased capacity for production as well as further improving the quality of the manufacturing processes.



C-Tech's pressure and temperature controlled autoclave can cure components up to 15.3m long and 1.44m in diameter in one piece. Max Internal Length: 15.3m Max Internal Diameter: 1.44m Max Temperature: 180°C Max Pressure: 7 bar

5 Axis CNC Router

Our Routech R200 5 Axis CNC router has an XYZ bed size of 5,500mm x 1,500mm x 1,000mm. It is used to machine foam cores, moulds, jigs, prototypes, 2D and 3D sheets and complete post production processing in house. The materials we primarily work with are composites, plastics, timber and tooling board, however we are not limited to just these. C-Tech offers a total post-production service by utilising our partner company Absolute CNC for the manufacture of CNC machined components, including aluminum moulds for proto-type or production runs.


Wrapping Machines

C-Tech has a range of custom built mandrel wrapping machines. The wrapping machines improve quality of laminate consolidation and can handle tubes up to 1200mm in diameter, 15m long.


3D Printing

As additive manufacturing technology rapidly develops C-Tech is keeping up to speed and integrating parts into our products. C-Tech's design capability means we are able to carry out in-house mechanical analysis. Plastic and titanium are most commonly used for short runs, prototypes or complex parts that are impossible to machine. Additive manufacturing is complementary to the services provided by our partner company Absolute CNC.


C-Tech processes over 30,000sqm of Pre-preg fibre each year. We use the latest materials available to satisfy the customers’ mechanical, chemical and heat requirements. Some of the materials used are: - Pre-preg, Carbon fibre, E-Glass, S-Glass and Kevlar - Epoxy and Phenolic resin systems - Standard, high and ultra-high modulus carbon fibres - Metals and alloys including titanium printed components - Core materials including honeycombs and foam

Manufacturing Processes

C-Tech has a well-equipped 2000sqm purpose built factory that was built in 2010 to meet all manufacturing needs. C-Tech's manufacturing processes include: Drawing, design, tool manufacture, mandrel wrapping (male moulding), female moulding, wet laminate, vacuum infusion, oven and autoclave curing, complete fit-out, painting and finishing of products. C-Tech offers a total post-production service by the manufacture of CNC machined components, including aluminium moulds for proto-type or production runs.
