Rapid Tooling
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
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.

Direct Manufacturing
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.



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

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

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.

The table below summarizes the standard tolerances of the parts produced by certified RapidDirect. Tolerances up to .0008” (0.020mm) are available upon request.


Part size / DimensionToleranceAngularity
< 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.
