Why Buyers Use This Manufacturing Route

  • 7075 aluminum machining: Suitable when the design requires a high-strength aluminum alloy and a lightweight machined component; the exact temper and material certificate requirements are project-dependent.
  • Turned geometry with cross-hole features: CNC turning can establish the main rotational features, while drilling, milling, or a second setup can address transverse holes and other non-rotational details.
  • Anodizing and PTFE-based coating coordination: Surface treatment can be planned around appearance, corrosion protection, wear, and friction requirements; coating thickness and masking must be defined on the drawing.
  • Engineering review before production: DFM review helps confirm datums, workholding, tool access, hole locations, edge conditions, and post-treatment allowances.
  • Inspection documentation by request: The documented resources include 6 QA/QC inspectors, 5 testing instruments, CMM measurement capability, 2D measuring instruments, and material/inspection documentation support subject to project requirements.

Product Overview

For a reliable quotation, please identify:

  • Functional mating surfaces and reference datums
  • Critical diameters and the transverse-hole position
  • Any required concentricity, perpendicularity, runout, or positional tolerance
  • Whether the pointed end is functional, decorative, or a lead-in feature
  • Coating coverage, masking areas, coating thickness, and allowable dimensional change
  • Required material condition, inspection report, and packaging method

Product-Specific Selling Points

  • Designed around the actual turned geometry: A stepped cylindrical body with a transverse opening requires more than a simple outside-diameter turning cycle. Engineering review can separate rotational features from cross-hole and secondary-operation requirements, helping the team plan workholding, datums, and inspection points before production.
  • 7075 aluminum with finishing planned as part of the process: 7075 aluminum is identified for this component, while the supplied information also specifies anodizing and a PTFE-based coating. Because both finishing operations can affect appearance and fit, the quotation should define the final condition and identify all surfaces that require masking or post-treatment measurement.
  • Control of mating features starts with the drawing: The cross-hole location, cylindrical diameters, end profile, and any mating shoulder may directly affect assembly. The buyer can identify critical features with datum references and GD&T call-outs. The documented general capability includes ±0.01 mm standard machining tolerance and ±0.005 mm for special areas, subject to geometry and engineering review.
  • Prototype-to-production support: The factory supports rapid prototyping, pilot runs, and production programs. A staged approach allows the buyer to validate fit, surface appearance, coating coverage, and inspection criteria on samples before releasing a larger order.
  • Inspection resources for drawing-based parts: The documented quality system includes incoming material inspection, first-article inspection, in-process or sampling inspection, and pre-shipment inspection. CMM and 2D measurement resources are available, with inspection reports and material certificates available according to the agreed project documentation.
  • One engineering review for multiple process needs: Shenzhen Perfect provides CNC turning, CNC milling, mill-turn machining, sheet metal, injection molding, casting, forging, rapid prototyping, and finishing coordination. If a project includes additional machined or molded components, the team can evaluate a consolidated manufacturing route while keeping each part controlled by its own drawing.
  • Confidential drawing-based OEM/ODM support: Customer drawings and product information are treated as confidential business information. NDAs can be requested before drawing exchange, and document control is used to maintain revision traceability. Any confidentiality commitment should be confirmed in the applicable commercial agreement.

Manufacturing Process and Quality Control

  1. Drawing and DFM review: The engineering team reviews the 2D drawing and 3D model for turning access, cross-hole machining, workholding, tool clearance, sharp edges, datum strategy, coating allowances, and inspection feasibility. If a tolerance appears tighter than the functional requirement, the team can flag the cost and process impact before quotation.
  2. Material verification: The buyer’s specified 7075 grade and temper are confirmed before production. Material certificates or mill test reports can be requested, and the required certificate type should be stated in the RFQ. Lot and documentation requirements should be agreed before material purchasing.
  3. CNC turning and secondary operations: The main rotational profile is planned for CNC turning. Transverse openings, flats, slots, or other non-rotational details may require drilling, milling, or a mill-turn route. The final process depends on the part’s datums and whether the design benefits from a single-setup or multi-setup strategy.
  4. Deburring and edge finishing: Edges and hole intersections are reviewed against the drawing. Unless otherwise specified, the buyer should define allowable burr condition, edge break, chamfer, and cosmetic requirements. Critical sealing or sliding areas should have explicit edge and surface call-outs.
  5. Anodizing and PTFE-based coating: The supplied product information indicates anodizing and a PTFE-based coating. The final quotation should identify the approved treatment supplier or process standard, color, coating thickness, coverage, masking, surface preparation, and dimensional allowance. If the coating is specified for friction or wear, the buyer should provide the relevant test or acceptance criteria.
  6. Dimensional inspection: Inspection planning may include critical diameter measurement, cross-hole position verification, feature location, visual finish inspection, and CMM or 2D measurement where appropriate. The inspection method, sampling plan, report format, and gauge requirements are agreed from the drawing and purchase order.
  7. Final inspection and export packaging: Finished parts are checked against the agreed drawing and surface-treatment requirements before packing. Packaging can be selected according to part finish and transit risk, including individual protection, separators, foam, export cartons, and custom labeling when requested.
