Materials include aluminium, stainless steel, titanium, polycarbonate, acetal and medical plastics. Particularly specialised in sealing faces and surfaces visible to the end customer. ### CNC Milling - [CNC Milling](https://claro.co.uk/cnc-milling/): 3, 4 and 5 axis milling plus horizontal 5 pallet machining. 5 axis technology is used for complex parts, enabling completion in two settings for repeatable accuracy. The 5-pallet horizontal machine offers accuracy and repeatability at a commercial cost for medium- and high-volume repeating requirements. CNC milling tolerance of +/- 0.01mm. Materials include aluminium, plastics, acetal, stainless steel, super duplex and titanium. All machines are fully maintained and checked for positional accuracy. ### 3D Printing - [3D Printing](https://claro.co.uk/3d-printing/): Uses the Markforged Mark Two, a continuous carbon fibre reinforcement printer with 0.1mm layer height and 3 axis movement. Enables production of complex and intricate parts in hours. Used to produce prototypes prior to volume batches at low cost to get products to market faster and identify design flaws early. ### Mechanical Design Service - [Mechanical Design Service](https://claro.co.uk/mechanical-design-service/): Over 35 years of experience in designing and manufacturing a wide range of products across subsea, audio, medical and laser sectors. Services include a full design service, design input and an engineering drawing service. Products designed include electronic housings, fishing reels, turntables and zone two computer housings for oil rigs. The aim is to ensure products are cost-effective to manufacture, with costs designed out at this key stage. ### Mechanical Assembly - [Mechanical Assembly](https://claro.co.uk/mechanical-assembly/): Parts are fully machined, anodised, plated, painted and then assembled by a team of time-served precision engineers. Assemblies include instrumentation and medical equipment. Assemblies are closely checked upon completion and, where requested, tested for performance. The service reduces customers' purchasing workload by supplying one line item rather than multiple, reducing admin and inventory, shortening in-house lead time, and freeing up space and capital. ### Quality Assured - [Quality Assured](https://claro.co.uk/quality-assured/): Two Mitutoyo CNC Coordinate Measurement Machines used for complex and critical part inspection, ensuring repeatability and reliability.
