    What's The Project Challenge For The Projects?

    The main challenge is the whole projects including plastic, metal and electronic devices assembly. The product parts appearance requirement is very high, ask us to inspect 100% without any flaw, and aluminum parts ask to make more 7 different anodizing colors without any colors distinction, then assembly with plastic parts. The final assembly that customers offers us the electronic devices for testing out and assembly.

    🔍 100% inspection — zero flaw tolerance on all appearance parts
    🎨 7+ anodizing colors with zero color distinction between batches
    🔧 Full project assembly: plastic + metal + electronic devices

    Our engineering team makes the production feasibility analysis for the project before production, since this is one full project assembly.

    • Plastic parts: We make DFM report, Tooling layout, and mold flow analysis to ensure the 1st shot succeeds.
    • Metal parts: We also make CNC program simulation to ensure tool path planning before production.

    How To Understand and Make The Whole Project?

    First, Creatingtec team conducted a careful design overview to understand the parts and suggest improvements when possible. Then, we make the product DFM and project proposed report for review before production.

    🔨 Fabricating The Prototypes — The first run of prototypes was CNC machined from aluminum in a 5-step process:

    1. CNC Program the Machines and Vacuum casting process.
    2. Engineering Review and Revise The Production Process.
    3. Mount the Workpiece on the Machine and Adjust the Setup.
    4. Monitor Production and All Functions.
    5. Do adjustment the Cutting and Casting Programs When Necessary.

    These practices are typically repeated in any CNC machining project and casting process; the cutting programs used are unique for each part. We had to consider things like machine type, part geometry, tool type, raw material, and steel materials.

    In our prototype workshop, our mechanician will make the prototype succeed, and offers production feasible suggestions.

    How To Develop and Manufacturing Injection Tooling Parts

    Most consumer electronics products include plastic parts, metal parts, and electronic devices — three parts assembled together. At the prototype stage for plastic parts, the product feature is very complex, so we have to use 5-axis CNC machining centers or vacuum casting processes to achieve the required quality. The product appearance includes better finishing, like anodizing, powder coat, silk-screen and more.

    Injection tooling parts require us to further consider the whole process from single part machining, surface coating, and assembly — this is a very complex process.

    📩 When you have consumer electronics and plastic parts inquiries, send your request to our engineering team — whether you need 1pc or more than 100,000pc, we will make the best cost-effective support for you. Tell us your requirement or expectation, and our team will make it happen. You can start a new project now.


    What's The Surface Finishing Can Be Done After CNC Machining and Injection Parts?

    After most of the electronic device parts are CNC machined and plastic tooled, we will provide quality finishing options including anodizing, powder coating, and silk-screen.

    🟦 Support & Cover Parts: CNC machining or Vacuum casting; injection tooling for mass production.
    🔲 Enclosure (Prototype & Low-Volume): 5-axis CNC + hard anodizing for surface protection.
    🏗️ Enclosure (Mass Production): Plastic tooling to complete efficiently at scale.

    Customer's Feedback For Our Electronic Device Parts CNC Machined

    We will ship these parts to our customers for assembling and testing, and will follow each detail for parts function and testing requirements to meet customer expectations. We then receive timely comments for new parts improvement, making each production run more perfect and smooth.
