Shenzhen Alu Rapid Prototype Precision Co., Ltd.

To get the best CNC prototyping from Shenzhen Alu Rapid Prototype Precision Co., Ltd. (often referred to as Alu Rapid Prototype or Alu Prototype), you need to leverage our specific strengths in aluminum machining and our digital "on-demand" workflow.

As of 2026, we have positioned themselves as a "one-stop" solution in Shenzhen, focusing on high-aesthetic and complex geometry parts for industries like aerospace, medical, and robotics.

1. Optimize Your RFQ (Request for Quote)

Alu Rapid Prototype uses an advanced online quotation platform. To get the most accurate pricing and fast lead times (often as quick as 3 business days), follow these file standards:

File Formats: Provide STEP (.stp) or IGES (.igs) files for 3D geometry. Include a PDF drawing for specific tolerances, thread callouts, and surface finish requirements.

Material Selection: While we handle many materials, we  specialize in aluminum. Specify the exact grade (e.g., 6061 for general use, 7075 for high strength, or 5052 for sheet metal) to ensure they pull from the right stock immediately.

Surface Finish: we are known for "Pure Aluminum" oxidation. If you need color-matched anodizing, provide a Pantone or RAL code upfront.

2. Utilize their DFM (Design for Manufacturability) Support

One of the biggest advantages of working with a precision-focused firm in Shenzhen is our engineering feedback.

Ask for a DFM Review: Before we cut metal, their engineers typically review the file. Ask us: "Can you optimize any internal radii to reduce tool changes?"

Pure Aluminum Breakthrough: If your project involves die casting but requires high-quality color anodizing (which is traditionally difficult with cast aluminum), ask about our specific technological breakthrough in pure aluminum die casting.

3. Precision and Quality Control

Since we operate under ISO 9001:2015 standards, you can hold uss to high-precision benchmarks:

Tolerances: We typically achieve ±0.01 mm to ±0.05 mm. If you have a critical fit, highlight it in your 2D drawing.

Inspection Reports: Explicitly request a First Article Inspection (FAI) or an OQC (Outgoing Quality Control) report. We have in-house CMM (Coordinate Measuring Machine) equipment to verify dimensions against your CAD model.

Comparison of Their Core CNC Services

Pro-Tips for Best Results:

Batching: If you are in the "Beta" prototyping phase, ask for a small batch (e.g., 5–10 pieces). CNC setup costs are high; the unit price drops significantly even between 1 and 5 units.

Surface Post-Processing: Alu Rapid is known for high-aesthetic finishes. If the part is for a trade show or "golden sample," specify Bead Blasting (120 mesh) followed by Type II Anodizing for a premium matte look.
