Prototype Machining

When you require precision, innovation and rapid turnaround times on machined prototype parts for evaluation and comparison prior to entering into full-scale production, you simply cannot beat the quality and expertise of American Micro Industries’ prototype machining services.

We serve the made-to-order parts and component needs of the aerospace/aviation, automotive, defense, electrical/electronics, marine, medical and technology industries. To ensure we always deliver top quality, we hold our CNC prototype machining to the highest standards while simultaneously striving to be the most responsive manufacturer in our field.

Prototype Machining

During the prototype machining process, we typically work closely with your designers and engineers to produce a low quantity of machined parts — sometimes even just one. During this crucial stage of your product’s realization, it’s essential to get every detail right. That’s why, regardless of the size or intricacy of your part, we'll give your order our full attention so that everything from the material you select to the type of machining we use results in the best possible first piece, which we'll then submit for your inspection and approval.

Based on our more than two decades of manufacturing made-to-order parts, we’re proud to offer a full line of prototype machining services that never sacrifice quality in order to meet your delivery deadlines.

Multiple Material Capabilities

Along with determining the size and application of a prototype part, it’s essential to choose the right material. American Micro Industries offers you one of the widest selections of materials of any manufacturer in the made-to-order parts industry.

The following are some of the materials we regularly use to construct prototypes:

  • Foams: Frequently used to sculpt prototypes for molds, carving foam is capable of holding small details and intricate shapes. Polyisocyanurate is one of the materials most commonly used to make carving foam, which is then offered in varying densities from #2 up to #6. Rigid foam is another classification of foam. It’s prized for its ability to resist heat and moisture, which makes it a prime material for building components and insulation.
  • G10 FR4 : Made of electrical alkali-free glass cloth impregnated with an epoxy resin, G10/FR4 is a popular choice for electrical insulation. Typically produced in sheets, it’s a highly flame-retardant material with noted dielectric stability — even at high humidity. It’s often used in the insulation of mechanical lines and appliance PCBs.
  • Phenolics: Available in sheets, rods, angles and U-channel forms, phenolics are a type of reinforced laminate made from a woven fabric impregnated with a phenolic resin binder. Certain phenolics offer excellent heat and arc resistance. Working with phenolic material requires skill and the latest machining equipment — both of which you can be assured you’ll get with American Micro Industries.
  • Plastics: A cost-efficient alternative to metals and other more expensive materials during the prototype phase, plastics are an affordable material for the fabrication of parts for almost any application. We have vast experience machining plastics of the following types: Acetal, Acrylics, Noryl®, PVC and CPVC, PVDF, Polycarbonate, Polypropylene, Teflon®, UHMW and HDPE — to name just a few.

Variety of Machining Types

Depending on the shape and complexity of your part, the accurate production of a prototype usually involves a form of computer numerical control — or CNC — machining in which the movement of the manufacturing machinery is controlled by computerized software. One of the greatest benefits of CNC prototype parts is that they’re produced quickly yet without losing the slightest detail from computer-aided design (CAD) or GibbsCAM software.

The three major CNC prototype machining options are as follows:

  • CNC milling holds the workpiece stationary while an assortment of drills and cutting tools create the desired shape.
  • CNC turning is a type of automated lathe that spins the workpiece against a cutting edge to produce the desired cylindrical shape.
  • CNC screw machining is much like turning, except screw machining is distinguished by its Swiss-style ability to produce small, intricate pieces — think of tiny components for Swiss watches — to within strict tolerances.
