FAQ Category

All FAQ List

  • Q What are the main factors that affect the price?

    A

    The primary cost drivers are:

    • Material Cost: Type of material and the raw stock size required.

    • Machine Time: Part complexity and total machining time (driven by machine hourly rate).

    • Tolerances: Tighter tolerances increase cost.

    • Surface Finishing: post-processing like anodizing, powder coating, plating, etc.

    • Order Quantity: Higher volumes typically benefit from lower per-unit pricing.

  • Q Do you offer Design for Manufacturability (DFM) analysis?

    A Yes, and we highly recommend it! Our engineers can review your design files free of charge and suggest optimizations to reduce cost, lead time, and improve quality without compromising functionality. This service often identifies significant savings.

  • Q Are there any design requirements?

    A

    Please ensure your design is manufacturable. Key things to consider:

    • Wall Thickness: Avoid very thin walls to prevent vibration or deformation during machining.

    • Internal Corners: Cutting tools are cylindrical, so internal corners will have a radius (fillet), not a perfect sharp edge.

    • Deep Pockets/Holes: Very deep features may require special tools and can increase cost.

    • Engraved Text: Specify the size and depth of any text clearly.

  • Q What files do I need to provide for a quote?

    A

    For the fastest and most accurate quote, please provide:

    • Preferred: 3D CAD model file (e.g., .STEP, .IGES, .XT).

    • Required: 2D engineering drawing (PDF or DWG) with all critical dimensions, tolerances, surface finish requirements, and material spec clearly called out.

    • We also offer reverse engineering services if you only have a physical sample or sketch.

  • Q What level of precision can you achieve?

    A Our standard machining tolerance typically holds ±0.001" to ±0.005" (±0.025mm to ±0.125mm). For critical features and precision components, we can achieve tolerances as tight as ±0.0005" (±0.012mm) using specialized equipment and processes. Final accuracy depends on part size, geometry, and material.

  • Q What materials can you machine?

    A

    We can machine a wide range of materials, including:

    • Metals: Aluminum (e.g., 6061, 7075), Stainless Steel (e.g., 303, 304, 316), Carbon Steel, Brass, Copper, Titanium.

    • Plastics: ABS, PC (Polycarbonate), POM (Acetal/Delrin), Nylon, PEEK, PTFE (Teflon).

    • Contact us if you have a specific material requirement.

  • Q What types of CNC machining services do you offer?

    A We primarily offer CNC Milling (ideal for complex 3D shapes and pockets) and CNC Turning (ideal for cylindrical or conical parts). We also provide CNC Turning-Milling Combination services for complex parts that can be completed in a single setup.

  • Q What is CNC machining?

    A CNC (Computer Numerical Control) machining is a manufacturing process where pre-programmed computer software dictates the movement of factory tools (like mills, lathes, or routers). It efficiently and precisely transforms a digital design file (like a 3D CAD model) into a custom-manufactured part from metal or plastic.

  • Q What is the tooling life for rapid tooling?

    A
    Normally, aluminum molds are good enough for +/- 1,000 shots, while Steel P20 molds can last for +/- 10,000 shots.
     

  • Q How fast can I get the moldings?

    A
    This depends on the size and geometry of the parts. For a common open and shut mold with regular size part such as 300 x 300 x 50 mm, fabrication of tools and moldings can be done within 2 weeks.
     

  • Q Why should I use rapid tooling/injection molding?

    A
    Injection molding is better suited to support larger amounts of samples for functional or market testing, bridge tooling, or low-volume production. If you need parts before a steel tool can be made (typically 6 to 10 weeks with other molders) or your volume requirements don't justify expensive steel production tooling, we can supply production parts to meet your full requirements (up to 10,000+ parts) in 1 to 15 days.
     

  • Q How Long Will Jucheng Precision Prototypes keep the Silicon Mold?

    A
    Silicion molds tend to deform after being kept for a long time, so we will keep them 30 days and then we will dispose them.
