MATERIALS
CNC Machining materials
We machine a wide range of metals, engineering plastics, and specialty materials available through our manufacturing network.
Aluminum
Lightweight, corrosion resistant, and easy to machine. The default choice for brackets, housings, and fixtures.
Stainless Steel
Corrosion resistance and strength for hardware, shafts, and parts exposed to harsh environments.
Carbon & Alloy Steel
High strength and wear resistance for load-bearing components and tooling.
Titanium
Exceptional strength-to-weight and biocompatibility for aerospace, motorsport, and medical parts.
Brass & Copper
Excellent machinability and conductivity for electrical and fluid-handling components.
Engineering Plastics
Delrin, Nylon, PEEK, PC, and ABS for lightweight, chemical-resistant, and insulating parts.
SURFACE FINISH
Surface finish options
Choose from a variety of finishing processes to match your project’s performance, durability, or aesthetic requirements.
As Machined
Parts are left with visible tool marks and no additional surface treatment. Ideal for functional prototypes or internal components where appearance isn’t critical.
Polished
Removes fine tool marks and smooths surfaces to a semi-gloss or gloss finish. Common for consumer-facing parts and aesthetic prototypes.
Sandblasting
Applies a matte, uniform texture by blasting the surface with fine abrasive media. Great for reducing glare and evening out surface imperfections.
Anodizing
An electrochemical process that increases corrosion resistance and allows for vibrant color finishes (commonly used for aluminum).
Powder Coating
A durable colored finish applied electrostatically and cured with heat. It resists wear, corrosion, and UV exposure, making it an excellent choice for outdoor or high-use parts.
Electroplating
A metallic coating applied through an electrochemical process. It adds corrosion resistance and aesthetic appeal and is commonly used for chrome, nickel, and gold finishes.

FAQ
Questions, answered
Have a question that is not answered here? Contact our engineering team directly and we will get back to you quickly.
What file types do you accept?
We accept major 3D CAD formats, including STEP, IGES, SolidWorks, Parasolid, and STL. PDF and DXF drawings are also helpful for communicating dimensions, tolerances, materials, and finish requirements.
How fast can parts be made?
Timing depends on the process, material, quantity, and complexity of your parts. Quotes are typically provided within 24 hours. Prototype orders may be completed in as little as 1 to 10 business days, while larger production orders may require additional time.
Can you hold tight tolerances?
Yes. We can hold tolerances as tight as ±0.001 inch on critical features when the material, geometry, and manufacturing process allow it. Include a drawing with your CAD files so our engineering team can review each tolerance requirement.
What industries do you serve?
We support customers across automotive, industrial equipment, consumer products, product development, and other industries that require dependable custom parts. Contact us to discuss the requirements for your application.
Do you offer surface finishing services?
Yes. Available finishes include anodizing, powder coating, plating, polishing, and other options based on the material and manufacturing process. Tell us your appearance and performance requirements when requesting a quote.
What happens after I submit a quote request?
Our engineering team reviews your files, material, quantity, tolerances, and finish requirements. We will contact you if we have questions, then provide clear pricing, estimated timing, and the next steps for production.
