CNC Machining Parts Production Process | Jucheng Precision
From CNC Prototypes To Low-volume Production
CNC Prototyping Services | Jucheng Precision
Protorypes
Prototyping is the process of creating a physical model of a product or part, typically using manufacturing techniques such as 3D printing. 
 
The purpose of prototyping is to test and refine the design, and to ensure that the product functions as intended. 
 
Prototyping can help to identify any design flaws or issues that may need to be addressed before moving into production.
CNC Machining Low-volume Manufacturing Services | Jucheng Precision
Low-volume Manufacturing
Low-volume manufacturing is a rapid production method that precedes full-scale production, ranging from 100 to 100,000 units. 
Jucheng Precision is committed to providing high-quality custom parts that strictly meet your design requirements and specifications via vast low-volume manufacturing services, including CNC machining, rapid injection molding, vacuum casting, sheet metal,reaction injection molding, and more. 
Low volume manufacturing allows companies to test their designs and products before investing in large-scale manufacturing, reducing the risk of product failure and financial loss.

How we check your parts?
Parts Drawing Checking | Jucheng Precision
 
Drawings Checking

we will check every item on the BOM like quantity, material, process, and surface finish requirements, and see if they are in accordance with the quotation. Meanwhile, our engineering team will check 3D and 2D drawings to see if there are any design errors, in accordance, with interference, and confirm all the tolerance are okay to be machined.

Meanwhile, DFM will be sent when it is necessary.
Incoming Material Inspection | Jucheng Precision  
Incoming Material inspection

We asked our material supplier to provide certification and paste marks for all the materials. And we will check the materials with Spectrometer to test the material chemical components.
In Processing Checking | Jucheng Precision
 
In processing checking

In this stage, we will go both with visual checking and manual checking.

Our experienced and skillful craftsman will check the parts with 3D drawings. 

We understand that it is very essential to check the parts when machining and avoid time-wasting. If necessary, we can provide you with the first sample when it comes to batch production.
Final Inspection | Jucheng Precision  
Final Inspection

We have 6 well-trained engineers in our QA department.

We can provide inspection reports like 3D scanning reports, Cleanness reports,100% dimensional reports, PPAP, Control Plans, etc.

FAQs

    Q My design is proprietary. How do you protect my IP?

    A We take client intellectual property (IP) extremely seriously. We are happy to sign a Non-Disclosure Agreement (NDA) before discussing your project. All customer files are stored on secure servers with access limited to essential project personnel. Your design will never be shared or used for any other purpose without your explicit permission.

  • Do you offer assembly services?

    Yes. We provide value-added services beyond machining, including cleaning, deburring, press-fit assembly, thread locking, and adhesive bonding, saving you time and simplifying your supply chain.

  • Do surface finishes affect part dimensions?

    Yes, they can. Coatings like anodizing or plating add a layer of material to the part surface, typically measured in microns (thousandths of a millimeter). If your part has critical functional dimensions, inform us beforehand so we can apply a pre-plate dimension compensation during machining.

  • What surface finishing options do you offer?

    We offer a wide range of finishes, including:

    • Anodizing (Type II & III): For aluminum, improves wear and corrosion resistance.

    • Bead Blasting / Sandblasting: Creates a uniform matte texture.

    • Plating: Such as nickel, chrome, or zinc plating for hardness and corrosion resistance.

    • Electroless Nickel Plating: Provides a uniform coating on complex geometries.

    • Passivation: For stainless steel, enhances rust resistance.

    • Painting & Silk Screening: For aesthetic parts.

  • Can I get inspection reports?

    Absolutely. For critical parts, we can provide full inspection reports (including dimensional data and material certifications) upon request for complete transparency.
