Explore how we make your parts—and support what comes next.
Coordinate milling, turning, EDM and grinding around one part drawing, with engineering support through inspection.
3-axis / 4-axis / 5-axis
Choose a larger injection molding batch to help lower unit cost. We store the molded parts free during the product lifecycle and arrange shipments to match your needs. This storage service applies to injection molding batch orders.
Explore injection moldingTwo sets of samples are sent for your testing, and bulk production starts after your approval. This is standard for injection molding and applies to CNC orders of more than 100 units of an individual part.
Multi-axis milling with direct engineering review of tool access, critical fits and inspection requirements.
Cutting, bends, joints and finishing reviewed as a finished enclosure, bracket or assembly rather than separate operations.
FDM, SLA or SLS selected around your prototype test, with the next machining or molding stage discussed when needed.
Turned fits and mating features reviewed together, with milling discussed where the same part needs additional features.
Small prototype batches planned around the master, casting resin and fit checks before a production mold is justified.
Machined brackets, housings, fixtures and prototype components for aerospace applications.

Our Dongguan site covers CNC, injection molding, sheet metal and surface finishing. A CNC factory in Denmark offers a second production option for European customers, with support from our Denmark office. Aria coordinates quality control across in-house work and approved partners.
More than 50 material and finishing partners, with quality control managed internally by Aria.
Watch design review, prototyping and manufacturing in action.
One clear path from your requirements to delivery.
Send your model and drawing, quantities, material, finish and required arrival date. Identify critical dimensions, cosmetic surfaces and any reports you need.
Discuss tool access, geometry, material and tolerances. For prototypes, confirm what needs to be tested; for molded parts, agree tooling and sample requirements.
Agree the price, process, inspection scope and delivery schedule. Keep approved files and design changes as the reference for the order.
Parts are made and specified features checked against the drawing. Follow agreed milestones through production and inspection.
Complete finishing and any assembly, then arrange packaging and shipping documents.
Reference your approved drawing for repeat orders and tell us what has changed.
Two process videos from RapidDirect show machining and resin printing in practice.
See how a CNC machining project moves through production inside RapidDirect's machine shop.
Follow preparation, printing, finishing, and completed parts in an SLA production example.
Agree the critical dimensions and inspection reports before production.
The dimensions, tolerances and cosmetic surfaces that matter to your part.
Measurement and sampling suited to the drawing and manufacturing process.
The reports and documents you have requested for your order.
Advice on CAD drawings, material selection and requesting a quote.
CNC machining materials are the metals, plastics, and composites cut into parts, chosen for strength, cost, and machinability.
Common CAD file formats for CNC machining include STEP, IGES, STL, and DXF, with STEP and IGES ...
Screw bosses in injection molding are raised features used for attaching screws or fasteners in plastic parts.
Plastic shrinkage affects every injection molded part. Learn what causes it, how different materials compare, and how to control it in mold design.
