CNC Aluminium Prototypes

The rapid nature of CNC parts for concept prototypes and for function prototype applications is particularly attractive for many NextProto clients. Our company and factory in China offers extensive rapid prototyping services and CNC capabilities to customers in the USA and UK. We can produce very complex prototypes in real engineering grade materials includes PEEK, Polycarbonate, ABS, PMMA, Nylon, Stainless Steel, Titanium and Aluminium. CNC process is capable of producing highly detailed prototype models and is cost-effective in terms of reducing lead times. Our CNC machined parts are typically able to be delivered within 3-7 working days. However for urgent projects it is always worth asking and we can put it on top priority for you. Painting can be done by us in-house according to your RAL or PANTONE references. Textured finish can be also added to the prototype models.

At NextProto, our rapid CNC prototyping service offers significant benefits for jigs and fixtures. When we found NextProto, we started with machining tool steels and aluminium tools. Since then, we also involved Aluminium and steel prototype machining for over 7 years. We have the best suppliers that can offer us anodizing, powder coating as well as alternative surface finishes and heat treatments for metal prototypes no matter just a one-off prototype project. We have many rapid prototyping projects each month using CNC prototypes for functional ergonomic models for automotive and aerospace industries.

Here just one tip about the new 3D Printing and the traditional CNC machining. In contrast to 3D Printing & Additive manufacturing techniques, Computer Numerically Controlled (CNC) machining is a subtractive process that produces parts directly from a 3D digital model. The process involves taking the original 3D CAD model data (preferably in STP or IGS format) and generating a cutter path using the latest CAD/CAM Premium computer-aided manufacturing (CAM) software. The required part originates as a block of raw material and the high-speed milling tool, following the pre-determined cutter path in the CAM software, removes the unwanted material to produce the finished part. NextProto machines in most plastic, steel and aluminium materials. We can build very large plastic parts and sometimes we will need to section it and glue the pieces together. Complex metal parts can be made by combining CNC milling, turning and EDM processes. After the part is milled, we can do sanding, polishing, painting and anodizing to it.
