Brief About Us

CNCProtos offers high-quality services for Rapid Prototyping and short-run manufacturing of production components. CNCProtos is part of an Australian based company - Arptech Pty Ltd - which has been serving the prototyping industry for 20 years. We specialise in CNC machining of plastic and metal components, catering to both individuals and large multinational companies.

We Value Our Clients

Our quality of work and customer service is second to none. That's why our business is built on returning customers with a majority being derived from word of mouth referrals. We work on a simple principle, to make promises which we can only fulfil. Our mission is to produce quality products from creative ideas, to help people succeed.

What's CNC Machining

CNC stands for Computer Numerical Control, referring to a computer "controller" which drives a machine tool. CNC Machining is one of our most widely used services, suitable for smooth, functional and accurate parts directly machined out of industry-grade plastics and metals. Some of the popular materials used by our clients are ABS, PC, Nylon, Acetal, Acrylic, Aluminium, Zinc and Stainless Steel.


CNC Machining in a Nutshell

What is the CNC Machining Process?

CNC Machining is a computerised manufacturing process to form complex shapes directly from 3D CAD models, using specialised software known as computer-aided manufacturing (CAM) which generates the NC machine code which drives the machine tool autonomously. CNC is an acronym for Computer Numerical Control. CNC Machining is a subtractive manufacturing process suitable for producing custom-designed parts by removing excessive material out of solid blocks of raw material.

Why CNC Machining, not 3d Printing?

CNC machining is a subtractive manufacturing process contrary to 3d printing which is an additive manufacturing process. It gives a leading advantage in some cases especially if products are large and bulky means you save a substantial amount of material cost in CNC machining. The main selling point of CNC machined parts is high-accuracy parts without compromising with material properties. Generally, CNC machined parts have a superior surface finish and strength as layering steps are not involved in the machining process.

What type of materials can be used?

There is a wide range of material choices for CNC machining including various grades of Plastics, Metals, Foams, Composites. Some of the common materials we use are ABS, Polycarbonate, Acrylic (PMMA), Acetal (POM), Nylon, PEEK, Glass Filled Nylon, Teflon, HDPE, PP, Chemical Wood, Aluminium, Stainless Steel, Zinc, Brass, Mild Steel.
