Finishes
RapidDirect provides surface finishes on all CNC parts, including anodizing, electroplating, bead blasting, polishing, brushing, powder coating, and painting.
Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc.
Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.
Powder coating forms a durable, wear resistant and corrosion resistant layer on the surface of parts. Powder coating can be used to apply colors to parts and is compatible with any metal.
Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.
Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.
Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. Most commonly applied to aluminum.
Painting the surface of a part improves its aesthetic appearance and can provide brand recognition to consumers. In addition, painting can have a protective effect on parts.
Tolerance
Standard tolerances are shown in the table below; we can work with you to achieve tighter values as needed.
| Part size / Dimension | Tolerance | Angularity |
|---|---|---|
| < 12’’ (30 mm) | ± .005’’ (0.125 mm) | ±0.5° |
| < 24’’ (60 mm) | ± .010’’ (0.250 mm) | ±1.0° |
| < 36’’ (90 mm) | ± 1/64’’ (0.400 mm) | ±1.0° |
Tips: Tighter tolerance are examined on a case by case basis with your technical drawings.
Applications
Rapid Tooling
Our CNC machining service is ideal for rapid tooling and can be used with almost any material. At RapidDirect, we specialize in the production of high quality tools used in injection molding and other tooling applications.
Rapid Prototyping
CNC Machining is ideal for prototyping applications for a number of reasons: it is compatible with a broad range of cost-effective materials, it produces precise parts and prototype turnaround times are rapid. We work with our customers to design and produce prototypes that meet their manufacturing requirements and quality standards.
End-Use Production
CNC Machining is commonly used for end-use production because of its precision, high-quality finishes and broad material compatibility. At RapidDirect, we offer customers a range of end-use materials, including plastics, aluminium and brass. We also provide the option to work with custom raw materials.
Quality Reports & Certifications
Full dimensional report
Details of all required part dimensions accompany the part, giving you peace of mind that the part will function and fit as designed.
Material certification
We provide material certification with our products, providing traceability to material characteristics.
First part verification
We can ship two sets of parts to the customer for verification on your request. Once the parts have been validated, we can move into full production.
