What are the best materials for automotive applications?

· Nylon

Suitable for 3D-printing of high fidelity prototypes and parts, nylon materials are used in SLS and Multi-jet fusion to make parts that are highly durable, workable, chemical, and temperature resistant. Nylon materials may be mixed with fillers to improve mechanical properties. It is widely used for making bushes, cams, bearings, gears, and weather-proof coatings.

· Thermoplastics

Thermoplastics can be excellently finished to make parts that are functional and attractive. Choose from Acetal, PEEK, Polycarbonate, ABS, Polyamide, Polyethylene, Polyurethane, etc to make bumpers, dashboards, seating applications, lighting, linings, covers, headlamps, and more.

best materials

· Liquid silicone rubber (LSR)

Liquid silicone rubbers are low-viscosity, high-purity elastomers used in liquid injection molding processes to make lens and lighting, gaskets, tubing, actuators, ignition coils, and seals.

· Aluminum

A general-purpose metal that has diverse use in any lightweight application and features that require a high strength-to-weight ratio.

Common Automotive Manufacturing Services

CNC Machining Services

· CNC Machining

First Part use 3, 4, and 5-axis CNC machines to carry out turning and milling operations that make aerospace parts with complex geometries, tight tolerances, and excellent finishes.

Sheet metal fabrication

· Sheet metal fabrication

Sheet metal forming is popular for processing aluminum, steel, and titanium sheets into prototypes and precision parts that work in direct applications. Our sheet metal services can make aircraft wings, blades, rotors, and other lightweight, high-strength components.

· Injection Molding

Injection molding is suitable for making thermoplastic materials into high volumes of interior components and high-performance parts for mechanical, cosmetic, and functional solutions in aircraft and defense systems.

Medical 3D Printing Services

· 3D Printing

Sheet metal forming is popular for processing aluminum, steel, and titanium sheets into prototypes and precision parts that work in direct applications. Our sheet metal services can make aircraft wings, blades, rotors, and other lightweight, high-strength components.

Urethane Casting Services

· Polyurethane Casting

Polyurethane casting serves small production, and quick prototyping of aircraft components for quick testing and pilot runs in production-grade materials. Polyurethane casting is very affordable, with low tooling costs and excellent surface finish.

Die Casting

· Die Casting

Die casting is suitable for the mass production of metal parts like aluminum, zinc, steel, and more. Firstpart die casting services can achieve complex geometries, tight tolerances, thin walls, and excellent dimensional accuracy. Castings for aerospace can also be finished in a wide array of surface textures.

· Aluminum Extrusion

Aluminum extrusion is a production process used to produce aluminum parts by forcing semi-molten aluminum through a shaped opening in a die using hydraulic pressure. The result is an elongated aluminum part with a profile similar to that of the mold.

First part Automotive Post-manufacturing/Finishing Services


Anodizing is primarily used to increase the thickness of the natural oxide layer on your part’s surface. It is prevalent for electronic products made from magnesium, aluminum, and titanium parts. It can be used for decorative, anti-corrosion, heat dissipation, or surface hardness treatments. Anodizing is also very ideal as a priming and painting surface treatment. At First Part, we offer Type 1, 2, and 3 anodizing. We also have chemical film anodizing options.

Hard Coat Anodizing

This process is similar to the anodizing. Hard coat anodizing uses a thicker anodizing thickness to enhance the properties of wear resistance, corrosion resistance and electrical insulation performance of your project.

Chromate Conversion Coating

The Aluminium chromate conversion process is directed at improving the corrosion resistance of wrought, heat-treatable and cast aluminium alloys and also provides an excellent base for subsequent painting or powder-coating services.


The “Alodine” is an international brand name used to describe the Henkel Adhesive Technologies conversion, anodizing and functional coatings that are applicable for use on Aluminium, Magnesium and a host of other non-ferrous alloys. Alodine coatings are excellent for providing improved protection against corrosion and easing paint adhesion on light metals and their alloys. The film can also be conductive.

Black Oxide/ Blackening

The blackening process utilizes black oxide to deliver enhanced rust protection. The process works by creating a conversion coating that works to isolate the air and protect your project.


Our passivation process is one of the best available in the industry. We use high quality passivation methods to add a light coat of protective material, such as a metal oxide, to provide a shell against corrosion on your project.
